基于区块链的数据处理方法及相关设备Blockchain-based data processing method and related equipment

技术领域technical field

本公开涉及区块链技术领域，具体而言，涉及一种基于区块链的数据处理方法、节点设备、终端设备、电子设备及计算机可读介质。The present disclosure relates to the technical field of block chains, in particular, to a data processing method based on block chains, node devices, terminal devices, electronic devices, and computer-readable media.

背景技术Background technique

区块链是分布式数据存储、点对点传输、共识机制、加密算法等计算机技术的新型应用模式。在分布式的节点系统中，由节点竞争获得当前处理数据的权力，作为区块生成节点；生成的区块再经过其他节点的验证确认后，再进行存储。上述运行机制使得区块链中记录在区块内的数据几乎不可能被篡改。Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In a distributed node system, nodes compete to obtain the right to process data as block generation nodes; the generated blocks are verified and confirmed by other nodes before being stored. The above operating mechanism makes it almost impossible for the data recorded in the block to be tampered with in the blockchain.

在业务场景中，常常出现业务方对幂等性的要求。例如，在支付场景中，用户购买商品后支付，支付扣款成功，但结果返回时网络异常导致用户以为未成功支付，一旦用户重复提交支付请求后，会发生针对同一笔订单进行第二次扣款的情况。In business scenarios, business parties often require idempotency. For example, in the payment scenario, the user pays after purchasing the product, and the payment deduction is successful, but when the result is returned, the network exception causes the user to think that the payment has not been successful. Once the user submits the payment request repeatedly, a second deduction will occur for the same order. payment situation.

在实际场景中，由于区块链响应延迟，可能出现业务方重复提交同一个业务的多笔交易请求，由于时间戳不一致等导致每笔交易的hash(哈希)值不一致，但是业务参数一致，区块链识别为多笔不同的业务请求，导致幂等性问题。幂等性是指分布式环境下，用户对于同一操作发起的一次或多次请求的结果是一致的，不会因为多次点击而产生副作用。In actual scenarios, due to the delayed response of the blockchain, the business party may repeatedly submit multiple transaction requests for the same business. Due to inconsistent timestamps, the hash (hash) value of each transaction is inconsistent, but the business parameters are consistent. The blockchain identifies multiple different business requests, leading to idempotency issues. Idempotency means that in a distributed environment, the results of one or more requests initiated by the user for the same operation are consistent, and there will be no side effects due to multiple clicks.

因此，需要一种新的基于区块链的数据处理方法、节点设备、终端设备、电子设备及计算机可读介质。Therefore, a new blockchain-based data processing method, node device, terminal device, electronic device, and computer-readable medium are needed.

本公开实施例所涉及的区块链(blockchain或block chain)是一种分布式数据存储、点对点(Peer to Peer，P2P)传输、共识机制、加密算法等计算机技术的新型应用模式，其本质上是一个去中心化的数据库，是一串使用密码学方法相关联产生的数据块，每一个数据块中包含了一批次网络交易的信息，用于验证其信息的有效性(防伪)和生成下一个区块。区块链可以包括区块链底层平台、平台产品服务层以及应用服务层；区块链可由多个借由密码学串接并保护内容的串连交易记录(又称区块)构成，用区块链所串接的分布式账本能让多方有效记录交易，且可永久查验此交易(不可篡改)。其中，共识机制是指区块链网络中实现不同节点之间建立信任、获取权益的数学算法，即共识机制是区块链各网络节点共同认可的一种数学算法。The blockchain (blockchain or block chain) involved in the embodiments of the present disclosure is a new application mode of computer technologies such as distributed data storage, point-to-point (Peer to Peer, P2P) transmission, consensus mechanism, and encryption algorithm. It is a decentralized database, which is a series of data blocks associated with cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate next block. The blockchain can include the underlying platform of the blockchain, the platform product service layer, and the application service layer; the blockchain can be composed of multiple concatenated transaction records (also known as blocks) that are connected and protected by cryptography. The distributed ledger connected by the block chain allows multiple parties to effectively record transactions, and this transaction can be permanently verified (not tamperable). Among them, the consensus mechanism refers to the mathematical algorithm that realizes the establishment of trust between different nodes and the acquisition of rights and interests in the blockchain network, that is, the consensus mechanism is a mathematical algorithm commonly recognized by all network nodes of the blockchain.

如图1所示，本公开实施例提供的基于区块链的数据处理系统可以包括区块链网络100及多个终端设备，图1中以包括三个终端设备为例，分别为第一终端201、第二终端202和第三终端203。其中，第一终端201、第二终端202和第三终端203可用于从区块链网络获取交易数据(包括交易请求或者执行交易请求后生成的交易数据)，或向区块链网络上传交易数据。As shown in Figure 1, the blockchain-based data processing system provided by the embodiment of the present disclosure may include a blockchain network 100 and multiple terminal devices. In Figure 1, three terminal devices are taken as an example, respectively the first terminal 201, a second terminal 202 and a third terminal 203. Among them, the first terminal 201, the second terminal 202 and the third terminal 203 can be used to obtain transaction data (including transaction requests or transaction data generated after executing transaction requests) from the blockchain network, or upload transaction data to the blockchain network .

如图2所示，图1实施例中的区块链网络100中可以包括多个节点设备101，多个节点设备101可以是指区块链网络中各个客户端，区块链网络100是指用于进行节点设备101与节点设备101之间数据共享的系统。每个节点设备101在进行正常工作时可以接收到交易数据，并基于接收到的交易数据维护该区块链网络100内的共享数据。为了保证区块链网络100内的信息互通，区块链网络100中的每个节点设备101之间可以存在信息连接，节点设备101之间可以通过上述信息连接进行信息传输。例如，当区块链网络100中的任意节点设备101接收到交易数据时，区块链网络100中的其他节点设备101便根据共识算法获取该交易数据，将该交易数据作为共享数据中的数据进行存储，使得区块链网络100中全部节点设备101上存储的数据均一致。As shown in Figure 2, the blockchain network 100 in the embodiment of Figure 1 may includemultiple node devices 101, themultiple node devices 101 may refer to each client in the blockchain network, and the blockchain network 100 refers to A system for sharing data betweennode devices 101 andnode devices 101 . Eachnode device 101 can receive transaction data during normal operation, and maintain shared data in the blockchain network 100 based on the received transaction data. In order to ensure the intercommunication of information in the blockchain network 100, there may be an information connection between eachnode device 101 in the blockchain network 100, and information transmission may be performed between thenode devices 101 through the above information connection. For example, when anynode device 101 in the blockchain network 100 receives transaction data,other node devices 101 in the blockchain network 100 will obtain the transaction data according to the consensus algorithm, and use the transaction data as the data in the shared data It is stored so that the data stored on allnode devices 101 in the blockchain network 100 are consistent.

其中，区块链网络100中的节点设备101、第一终端201、第二终端202和第三终端203可以为任意的电子设备，包括但不限于手机、平板电脑、笔记本电脑、掌上电脑、智能音响、移动互联网设备(mobile internet device，MID)、POS(Point Of Sales，销售点)机、可穿戴设备(例如智能手表、智能手环等)；还可以是一台独立的服务器、或由若干台服务器组成的服务器集群、或云计算中心。Among them, thenode device 101, the first terminal 201, the second terminal 202 and the third terminal 203 in the block chain network 100 can be any electronic devices, including but not limited to mobile phones, tablet computers, notebook computers, palmtop computers, smart Audio, mobile Internet device (mobile internet device, MID), POS (Point Of Sales, point of sale) machine, wearable device (such as smart watch, smart bracelet, etc.); A server cluster composed of several servers, or a cloud computing center.

对于区块链网络100中的每个节点设备101，均具有与其对应的节点设备标识，而且区块链网络100中的每个节点设备101均可以存储有区块链网络100中其他节点设备101的节点设备标识，以便后续根据其他节点设备101的节点设备标识，将生成的区块广播至区块链网络100中的其他节点设备101。每个节点设备101中可维护一个如下表1所示的节点设备标识列表，将节点设备名称和节点设备标识对应存储至该节点设备标识列表中。其中，节点设备标识可为IP(Internet Protocol，网络之间互联的协议)地址以及其他任一种能够用于标识该节点设备的信息，表1中仅以IP地址为例进行说明。其中N为大于或等于1的正整数。For eachnode device 101 in the blockchain network 100, there is a corresponding node device identifier, and eachnode device 101 in the blockchain network 100 can storeother node devices 101 in the blockchain network 100 The node device identification ofother node devices 101 in order to subsequently broadcast the generated block toother node devices 101 in the blockchain network 100 according to the node device identifications ofother node devices 101. Eachnode device 101 may maintain a node device identifier list as shown in Table 1 below, and store the node device name and the node device identifier in the node device identifier list correspondingly. Wherein, the node device identifier can be an IP (Internet Protocol, a protocol for interconnection between networks) address and any other information that can be used to identify the node device. Table 1 only uses the IP address as an example for illustration. Wherein N is a positive integer greater than or equal to 1.

区块链网络100中的每个节点设备101均存储一条相同的区块链。区块链由多个区块组成，每一个区块包含了前一个区块的加密散列(可以用默克尔树(Merkle tree)算法计算的散列值表示)、相应时间戳以及交易数据，这样的设计使得区块内容具有难以篡改的特性。Eachnode device 101 in the blockchain network 100 stores the same blockchain. The blockchain consists of multiple blocks, and each block contains the encrypted hash of the previous block (which can be represented by the hash value calculated by the Merkle tree algorithm), the corresponding timestamp and transaction data , such a design makes the block content difficult to tamper with.

参见图3，区块链由多个区块组成，创始块中包括区块头和区块主体，区块头中存储有交易数据特征值、版本号、时间戳和难度值，区块主体中存储有交易数据；创始块的下一区块以创始块为父区块，下一区块中同样包括区块头和区块主体，区块头中存储有当前区块的交易数据特征值、父区块的区块头特征值、版本号、时间戳和难度值，并以此类推，使得区块链中每个区块中存储的区块数据均与父区块中存储的区块数据存在关联，保证了区块中交易数据的安全性。Referring to Figure 3, the blockchain is composed of multiple blocks. The genesis block includes a block header and a block body. The block header stores transaction data characteristic values, version numbers, timestamps, and difficulty values. The block body stores Transaction data; the next block of the genesis block takes the genesis block as the parent block, and the next block also includes the block header and block body. The block header stores the transaction data characteristic value of the current block, the parent block’s The block header feature value, version number, timestamp and difficulty value, and so on, make the block data stored in each block in the blockchain related to the block data stored in the parent block, ensuring Security of transaction data in blocks.

在生成区块链中的各个区块时，参见图4，区块链所在的节点设备在接收到交易数据时，对交易数据进行校验，完成校验后，将交易数据存储至内存池中，并更新其用于记录交易数据的哈希树；之后，将更新时间戳更新为接收到交易数据的时间，并尝试不同的随机数，多次进行特征值计算，使得计算得到的特征值可以满足下述公式：When generating each block in the blockchain, see Figure 4. When the node device where the blockchain is located receives the transaction data, it verifies the transaction data. After the verification is completed, the transaction data is stored in the memory pool , and update the hash tree used to record the transaction data; after that, update the update timestamp to the time when the transaction data is received, try different random numbers, and perform eigenvalue calculations multiple times, so that the calculated eigenvalues can be satisfy the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))＜TARGET (1)SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))＜TARGET (1)

其中，SHA256为计算特征值所用的特征值算法；version(版本号)为区块链中相关区块协议的版本信息；prev_hash为当前区块的父区块的区块头特征值；merkle_root为交易数据的特征值；ntime为更新时间戳的更新时间；nbits为当前难度，在一段时间内为定值，并在超出固定时间段后再次进行确定；x为随机数；TARGET为特征值阈值，该特征值阈值可以根据nbits确定得到。Among them, SHA256 is the eigenvalue algorithm used to calculate the eigenvalue; version (version number) is the version information of the relevant block protocol in the blockchain; prev_hash is the block header eigenvalue of the parent block of the current block; merkle_root is the transaction data ntime is the update time of the update timestamp; nbits is the current difficulty, which is a fixed value for a period of time, and will be determined again after a fixed period of time; x is a random number; TARGET is the threshold of the feature value, the feature The value threshold can be determined according to nbits.

这样，当计算得到满足上述公式的随机数时，便可将信息对应存储，生成区块头和区块主体，得到当前区块。随后，区块链所在节点设备根据区块链网络100中其他节点设备的节点设备标识，将新生成的区块分别发送给其所在的区块链网络100中的其他节点设备，由其他节点设备对新生成的区块进行校验，并在完成校验后将新生成的区块添加至其存储的区块链中。In this way, when the random number satisfying the above formula is calculated, the information can be stored correspondingly, the block header and block body are generated, and the current block is obtained. Subsequently, according to the node device identifiers of other node devices in the blockchain network 100, the node device where the blockchain is located sends the newly generated blocks to other node devices in the blockchain network 100 where it is located, and the other node devices Verify the newly generated block, and add the newly generated block to its stored blockchain after the verification is completed.

图5示意性示出了根据本公开的一个实施例的基于区块链的数据处理方法的流程图。本公开实施例所提供的方法可以由任意具备计算处理能力的电子设备处理，例如上述图2实施例中的任意节点设备101。Fig. 5 schematically shows a flowchart of a blockchain-based data processing method according to an embodiment of the present disclosure. The method provided by the embodiments of the present disclosure may be processed by any electronic device with computing processing capability, for example, anynode device 101 in the above-mentioned embodiment of FIG. 2 .

图5实施例中，以所提供的方法应用于区块链网络100中的节点设备101为例，区块链网络100中部署智能合约，该智能合约可用于维护交易执行表，该交易执行表中用于记录历史上执行成功的交易的相关信息，以用于对重复接收到的针对同一业务的交易请求进行去重，防止同一业务被重复执行，保证幂等性。In the embodiment of Fig. 5, taking the provided method applied to thenode device 101 in the blockchain network 100 as an example, the smart contract is deployed in the blockchain network 100, and the smart contract can be used to maintain the transaction execution table, the transaction execution table It is used to record the relevant information of successfully executed transactions in history, so as to deduplicate repeatedly received transaction requests for the same business, prevent the same business from being executed repeatedly, and ensure idempotency.

其中，智能合约，是一种旨在以信息化方式传播、验证或执行合同的计算机协议，可以执行某个合约的条款，通过部署在共享账本上的用于满足一定条件时而执行的代码实现，根据实际的业务需求代码用于完成自动化的交易，例如查询买家所购买的物流状态，在买家签收货物后将买家的电子货币转移到商家的地址；当然，智能合约不仅限于执行用于交易的合约，还可以执行对接收的信息进行处理的合约。智能合约允许在没有第三方的情况下进行可信交易，这些交易可追踪且不可逆转。Among them, a smart contract is a computer protocol designed to disseminate, verify or execute a contract in an informatized manner. It can execute the terms of a contract and implement it through code deployed on a shared ledger that is executed when certain conditions are met. According to actual business needs, the code is used to complete automated transactions, such as querying the logistics status of the buyer's purchase, and transferring the buyer's electronic currency to the merchant's address after the buyer signs for the goods; of course, smart contracts are not limited to execution. The contract for transactions can also execute the contract for processing the received information. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible.

区块链上的智能合约是在区块链上可以被交易触发执行的合约。智能合约可以通过代码的形式定义。Smart contracts on the blockchain are contracts that can be triggered by transactions on the blockchain. Smart contracts can be defined in the form of code.

以以太坊为例，支持用户在以太网网络中创建并调用一些复杂的逻辑。以太坊作为一个可编程区块链，其核心是以太坊虚拟机(Ethereum Virtual Machine，EVM)，每个以太坊节点都可以运行EVM。EVM是一个图灵完备的虚拟机，通过它可以实现各种复杂的逻辑。用户在以太坊中发布和调用智能合约就是在EVM上运行的。实际上，EVM直接运行的是虚拟机代码(虚拟机字节码，简称“字节码”)，所以部署在区块链上的智能合约可以是字节码。Taking Ethereum as an example, it supports users to create and call some complex logic in the Ethereum network. As a programmable blockchain, Ethereum has an Ethereum Virtual Machine (Ethereum Virtual Machine, EVM) at its core, and each Ethereum node can run the EVM. EVM is a Turing-complete virtual machine through which various complex logic can be realized. Users publish and call smart contracts in Ethereum that run on the EVM. In fact, EVM directly runs the virtual machine code (virtual machine bytecode, referred to as "bytecode"), so the smart contract deployed on the blockchain can be bytecode.

本公开实施例中的任意一个智能合约可以通过以下方式部署到区块链网络上，但本公开并不限定于此。用户将一笔包含创建智能合约的交易(transaction)发送到区块链网络后，各节点均可以在EVM中执行这笔交易。其中，交易中的From字段用于记录发起创建智能合约的账户的地址，交易的Data字段的字段值保存的合约代码可以是字节码，交易的To字段的字段值为一个null(空)的账户。当节点间通过共识机制达成一致后，这个智能合约成功创建，后续用户可以调用这个智能合约。Any smart contract in the embodiments of the present disclosure can be deployed on the blockchain network in the following manner, but the present disclosure is not limited thereto. After the user sends a transaction including the creation of a smart contract to the blockchain network, each node can execute the transaction in the EVM. Among them, the From field in the transaction is used to record the address of the account that initiated the creation of the smart contract, the contract code saved in the field value of the Data field of the transaction can be a bytecode, and the field value of the To field of the transaction is a null (empty) account. When the nodes reach an agreement through the consensus mechanism, the smart contract is successfully created, and subsequent users can call the smart contract.

每个智能合约创建后，区块链上出现一个与各个智能合约对应的合约账户，并拥有一个特定的地址。合约代码(Code)将保存在该合约账户的账户存储(Storage)中。智能合约的行为由合约代码控制，而智能合约的账户存储则保存了合约的状态。即智能合约使得区块链上产生包含合约代码和账户存储的虚拟账户。在一个智能合约中可以声明多种成员，包括状态变量、函数、函数修改器、事件等。状态变量是永久存储在智能合约的账户存储(Storage)字段中的值，用于保存智能合约的状态。After each smart contract is created, a contract account corresponding to each smart contract appears on the blockchain and has a specific address. The contract code (Code) will be saved in the account storage (Storage) of the contract account. The behavior of the smart contract is controlled by the contract code, and the account storage of the smart contract saves the state of the contract. That is, the smart contract makes a virtual account containing contract code and account storage generated on the blockchain. Various members can be declared in a smart contract, including state variables, functions, function modifiers, events, etc. The state variable is a value permanently stored in the account storage (Storage) field of the smart contract, which is used to save the state of the smart contract.

在步骤S510中，获取第一请求方的终端设备发送的第一交易请求，所述第一交易请求携带第一业务方标识、第一请求方信息和用于执行所述第一交易请求的第一传入参数。In step S510, the first transaction request sent by the terminal device of the first requesting party is obtained, the first transaction request carries the first business party identification, the first requesting party information and the first transaction request for executing the first transaction request. A parameter is passed in.

本公开实施例中，第一请求方可以是任意业务方，第一请求方的终端设备可以是任意终端设备，在下面的举例说明中，以图1中的第一终端201为例进行举例说明，但本公开并不限定于此。In the embodiment of the present disclosure, the first requesting party may be any business party, and the terminal device of the first requesting party may be any terminal device. In the following examples, the first terminal 201 in FIG. 1 is used as an example for illustration , but the disclosure is not limited thereto.

第一终端201可以向区块链网络100中上传第一交易请求，相应地，区块链网络100中的任意节点设备101均可以接收到第一终端201所发送的第一交易请求。该第一交易请求中可以携带第一业务方标识、第一请求方信息和第一传入参数。The first terminal 201 can upload the first transaction request to the blockchain network 100 , and correspondingly, anynode device 101 in the blockchain network 100 can receive the first transaction request sent by the first terminal 201 . The first transaction request may carry the first business party identifier, first requester information and first incoming parameters.

其中，该第一业务方标识是第一请求方在发送第一交易请求之前生成的，以用于唯一区别该第一交易请求所针对的操作对象的标识，例如，若第一交易请求所针对的操作对象是第一数据集中的某个文件，则第一业务方标识可以是第一请求方在第一终端201上生成的该文件的文件名。再例如，若第一交易请求所针对的操作对象是某笔资产，则第一业务方标识可以是该资产的标识。本公开对第一业务方标识的形式不做限定，只要其能够将第一交易请求所针对的操作对象与其他操作对象唯一区别开来即可。Wherein, the first business party identifier is generated by the first requesting party before sending the first transaction request, so as to uniquely distinguish the identifier of the operation object targeted by the first transaction request. For example, if the first transaction request targets If the operation object is a certain file in the first data set, the first business party identifier may be the file name of the file generated by the first requesting party on the first terminal 201 . For another example, if the operation object targeted by the first transaction request is a certain asset, the identifier of the first business party may be the identifier of the asset. The present disclosure does not limit the form of the first business party identifier, as long as it can uniquely distinguish the operation object targeted by the first transaction request from other operation objects.

该第一请求方信息可以包括任意能够用于唯一区别该第一请求方或者该第一请求方的终端设备的标识，例如第一请求方的用户名，第一请求方的终端设备的网络地址、设备编号等。The first requester information may include any identifier that can be used to uniquely distinguish the first requester or the first requester's terminal device, such as the first requester's username and the network address of the first requester's terminal device , device number, etc.

第一传入参数可以包括为了能够执行该第一交易请求所需要的任意输入参数。例如，若第一交易请求是请求将数量为10的电子资源从账户1转移至账户2，则第一传入参数可以包括第一交易账户和大小为10的第一交易量，第一交易账户可以包括作为第一转出账户的账户1和作为第一转入账户的账户2。The first incoming parameter may include any input parameter required to be able to execute the first transaction request. For example, if the first transaction request is a request to transfer 10 electronic resources from account 1 to account 2, the first incoming parameter may include the first transaction account and the first transaction amount of 10, the first transaction account It may include account 1 as the first transfer-out account and account 2 as the first transfer-in account.

在步骤S520中，调用所述智能合约生成所述第一传入参数的第一传参哈希值。In step S520, the smart contract is invoked to generate a first hash value of the first incoming parameter.

节点设备101可以调用智能合约，采用哈希函数生成第一传入参数的第一传参哈希值。第一传参哈希值是根据第一交易请求传入的第一传入参数计算获得的数据指纹。Thenode device 101 may call the smart contract, and use a hash function to generate a first passed parameter hash value of the first passed parameter. The hash value of the first passed parameter is the data fingerprint calculated according to the first passed parameter passed in by the first transaction request.

本公开实施例中所提及的哈希函数可以采用SHA(Security Hash Algorithm，安全哈希算法)函数，例如SHA256、SHA3等任意一种合适的函数，本公开对此不做限定。The hash function mentioned in the embodiments of the present disclosure may use a SHA (Security Hash Algorithm, secure hash algorithm) function, such as any suitable function such as SHA256 and SHA3, which is not limited in the present disclosure.

在步骤S530中，调用所述智能合约将所述第一业务方标识、所述第一请求方信息和所述第一传参哈希值与所述交易执行表匹配。In step S530, the smart contract is invoked to match the first business party identifier, the first requester information, and the first parameter hash value with the transaction execution table.

在一些实施例中，若交易执行表中记录了历史上执行成功的交易请求的业务方标识、请求方信息、传参哈希值、交易执行结果和交易哈希值，则可以将第一交易请求中携带的第一业务方标识、第一请求方信息和上述步骤计算获得的第一传参哈希值分别与交易执行表中已经记录的各个交易请求的业务方标识、请求方信息和传参哈希值进行比较，查询交易执行表中的业务方标识是否存在与第一业务方标识相同的目标业务方标识，查询交易执行表中的请求方信息是否存在与第一请求方信息相同的目标请求方信息，查询交易执行表中的传参哈希值是否存在与第一传参哈希值相同的目标传参哈希值，若存在与之一一匹配的目标业务方标识、目标请求方信息和目标传参哈希值，则判定为匹配成功，即历史上已经执行过与该第一交易请求相同的业务，可以从交易执行表中获取与目标业务方标识、目标请求方信息和目标传参哈希值关联存储的目标交易执行结果和目标交易哈希值；反之，则判定为匹配失败，即历史上尚未执行过与该第一交易请求相同的业务。In some embodiments, if the business party ID, requester information, reference hash value, transaction execution result, and transaction hash value of the transaction request successfully executed in history are recorded in the transaction execution table, the first transaction can be The first business party ID carried in the request, the first requester information, and the first parameter hash value calculated in the above steps are respectively compared with the business party ID, requester information, and passed data of each transaction request that have been recorded in the transaction execution table. Compare the reference hash value, check whether the business party ID in the transaction execution table has the same target business party ID as the first business party ID, and check whether the requester information in the transaction execution table has the same target business party ID as the first requester information Target requester information, query whether the passed parameter hash value in the transaction execution table has the same target passed parameter hash value as the first passed parameter hash value, if there is a target business party ID, target request Party information and the hash value of the target passed parameters, it is determined that the match is successful, that is, the same business as the first transaction request has been executed in history, and the target business party ID, target requester information and The target transaction execution result and the target transaction hash value are associated with the stored target transaction hash value; otherwise, it is determined that the matching fails, that is, the same business as the first transaction request has not been executed in history.

本公开实施例中，历史上已经执行过与该第一交易请求相同的业务是指，在第一交易请求之前，已经执行过与该第一交易请求所针对的操作对象相同、且针对该操作对象所执行的交易操作也相同的交易请求，同时该之前成功执行的交易请求也是由该第一交易请求的发起者(第一请求方)发起，即该之前成功执行的交易请求的业务方标识与第一业务方标识相同，请求方信息与该第一请求方信息相同，传入参数和该第一传入参数(这里是通过判断传参哈希值与该第一传参哈希值相同来确定的)，当上述三个参数存在任意一个不一致时，则可以确定历史上尚未执行过与该第一交易请求相同的业务。通过在交易执行表中关联记录已经成功执行的交易的业务方标识、请求方信息和传参哈希值，从而可以针对相同业务的多笔交易请求区分出来，满足幂等性要求，防止同一笔业务被重复执行，保证交易执行的安全性和可靠性。In the embodiments of the present disclosure, the same business as the first transaction request has been executed in history means that, before the first transaction request, the same operation object as the first transaction request has been executed, and for the operation The transaction operation performed by the object is also the same transaction request, and the transaction request that was successfully executed before is also initiated by the initiator of the first transaction request (the first requester), that is, the business party ID of the transaction request that was successfully executed before The same as the first business party ID, the requester information is the same as the first requester information, the incoming parameter and the first incoming parameter (here by judging that the passed parameter hash value is the same as the first passed parameter hash value determined), when any one of the above three parameters is inconsistent, it can be determined that the same business as the first transaction request has not been executed in history. By associating and recording the business party ID, requester information, and parameter hash value of the successfully executed transaction in the transaction execution table, multiple transaction requests for the same business can be distinguished, meeting the idempotency requirements, and preventing the same The business is executed repeatedly to ensure the safety and reliability of transaction execution.

在另一些实施例中，若交易执行表中记录了历史上执行成功的交易请求的业务方标识、平台方标识、请求方信息、传参哈希值、交易执行结果和交易哈希值，则节点设备可以根据第一业务方标识(例如这里用a表示)给第一交易请求所针对的操作对象分配一个第一平台方标识(例如这里用A表示)，其中，节点设备针对同一操作对象所分配的平台方标识是相同的，节点设备接收到不同的交易请求，但若这些不同的交易请求中的业务方标识是相同的，则生成的平台方标识也是相同的，即平台方标识是根据业务方标识生成的，各个平台方标识也具有唯一性，例如假设第一业务方标识为操作对象为文件1的文件名，则第一平台方标识可以是ABC。然后，节点设备可以将第一交易请求中携带的第一业务方标识、第一请求方信息和上述步骤计算获得的第一传参哈希值、以及节点设备生产的第一平台方标识分别与交易执行表中已经记录的各个交易请求的业务方标识、请求方信息、传参哈希值和平台方标识进行比较，查询交易执行表中的业务方标识是否存在与第一业务方标识相同的目标业务方标识，查询交易执行表中的请求方信息是否存在与第一请求方信息相同的目标请求方信息，查询交易执行表中的传参哈希值是否存在与第一传参哈希值相同的目标传参哈希值，查询交易执行表中的平台方标识是否存在与第一平台方标识相同的目标平台方标识，若存在与之一一匹配的目标业务方标识、目标请求方信息、目标传参哈希值和目标平台方标识，则判定为匹配成功，即历史上已经执行过与该第一交易请求相同的业务，可以从交易执行表中获取与目标业务方标识、目标请求方信息、目标传参哈希值和目标平台方标识关联存储的目标交易执行结果和目标交易哈希值；反之，则判定为匹配失败，即历史上尚未执行过与该第一交易请求相同的业务。In other embodiments, if the transaction execution table records the business party ID, platform party ID, requester information, passed parameter hash value, transaction execution result and transaction hash value of the transaction request executed successfully in history, then The node device may allocate a first platform party identifier (for example, A here) to the operation object targeted by the first transaction request according to the first business party identifier (for example, represented by a here), wherein, the node device for the same operation object The assigned platform party IDs are the same, and node devices receive different transaction requests, but if the business party IDs in these different transaction requests are the same, the generated platform party IDs are also the same, that is, the platform party IDs are based on The identification of the business party is generated, and each platform identification is also unique. For example, assuming that the first business identification is the name of the file whose operation object is file 1, the first platform identification can be ABC. Then, the node device can combine the first business party ID carried in the first transaction request, the first requester information, the first parameter hash value calculated by the above steps, and the first platform party ID produced by the node device with Compare the business party ID, requester information, reference hash value and platform party ID of each transaction request recorded in the transaction execution table, and check whether the business party ID in the transaction execution table is the same as the first business party ID Target business party ID, query whether the requester information in the transaction execution table has the same target requester information as the first requester information, query whether the passed parameter hash value in the transaction execution table is the same as the first passed parameter hash value For the same target parameter hash value, check whether the platform party ID in the transaction execution table has the same target platform party ID as the first platform party ID, and if there is a target business party ID and target requester information that matches one by one , the hash value of the target passed parameters and the target platform party ID, it is determined that the match is successful, that is, the same business as the first transaction request has been executed in history, and the target business party ID, target request can be obtained from the transaction execution table Party information, target parameter hash value, and target platform party identifier store the target transaction execution result and target transaction hash value; otherwise, it is judged as a matching failure, that is, the same transaction request as the first transaction request has not been executed in history. business.

本公开实施例中，历史上已经执行过与该第一交易请求相同的业务是指，在第一交易请求之前，已经执行过与该第一交易请求所针对的操作对象相同、且针对该操作对象所执行的交易操作也相同的交易请求，同时该之前成功执行的交易请求也是由该第一交易请求的发起者(第一请求方)发起，即该之前成功执行的交易请求的业务方标识与第一业务方标识以及平台方标识与第一平台方标识相同，请求方信息与该第一请求方信息相同，传入参数和该第一传入参数(这里是通过判断传参哈希值与该第一传参哈希值相同来确定的)，当上述四个参数存在任意一个不一致时，则可以确定历史上尚未执行过与该第一交易请求相同的业务。通过在交易执行表中关联记录已经成功执行的交易的业务方标识、请求方信息、传参哈希值和平台方标识，一方面，可以针对相同业务的多笔交易请求区分出来，满足幂等性要求，防止同一笔业务被重复执行，保证交易执行的安全性和可靠性；另一方面，通过业务方标识和平台方标识来联合标识交易请求所针对的操作对象，即由多方来维护操作对象的唯一标识，而不是单纯由业务方来维护，可以进一步确定不同交易请求所针对的是同一操作对象，进一步保证交易执行的安全性和可靠性。In the embodiments of the present disclosure, the same business as the first transaction request has been executed in history means that, before the first transaction request, the same operation object as the first transaction request has been executed, and for the operation The transaction operation performed by the object is also the same transaction request, and the transaction request that was successfully executed before is also initiated by the initiator of the first transaction request (the first requester), that is, the business party ID of the transaction request that was successfully executed before The ID of the first business party and the ID of the platform party are the same as the ID of the first platform party, the information of the requester is the same as that of the first requester, and the incoming parameters and the first incoming parameters (here by judging the hash value of the passed parameters and the hash value of the first passed parameter), when any one of the above four parameters is inconsistent, it can be determined that the same business as the first transaction request has not been executed in history. By associating and recording the business party ID, requester information, passed parameter hash value and platform party ID of the successfully executed transaction in the transaction execution table, on the one hand, multiple transaction requests for the same business can be distinguished, satisfying idempotence To prevent the same business from being executed repeatedly, and ensure the security and reliability of transaction execution; on the other hand, the operation object targeted by the transaction request is jointly identified through the business party ID and the platform party ID, that is, the operation is maintained by multiple parties The unique identification of the object, instead of being maintained solely by the business side, can further determine that different transaction requests are aimed at the same operation object, further ensuring the security and reliability of transaction execution.

在又一些实施例中，若交易执行表中记录了历史上执行成功的交易请求的数据实体标识、请求方信息、传参哈希值、交易执行结果和交易哈希值，该数据实体标识是根据已经执行成功的交易请求的业务方标识和平台方标识生成的，例如级联该业务方标识和该平台方标识生成该数据实体标识，或者对该业务方标识和该平台方标识计算哈希值，获得该数据实体标识，本公开对此不做限定，则节点设备可以根据第一业务方标识给第一交易请求所针对的操作对象分配一个第一平台方标识，之后，节点设备可以根据第一业务方平台和第一平台方标识生成第一数据实体标识，该第一数据实体标识的生成方式不做限定，只要能够唯一区别第一交易请求所针对的操作对象即可。然后，节点设备可以将第一交易请求的第一数据实体标识、第一请求方信息和上述步骤计算获得的第一传参哈希值分别与交易执行表中已经记录的各个交易请求的数据实体标识、请求方信息和传参哈希值进行比较，查询交易执行表中的数据实体标识是否存在与第一数据实体标识相同的目标数据实体标识，查询交易执行表中的请求方信息是否存在与第一请求方信息相同的目标请求方信息，查询交易执行表中的传参哈希值是否存在与第一传参哈希值相同的目标传参哈希值，若存在与之一一匹配的目标数据实体标识、目标请求方信息和目标传参哈希值，则判定为匹配成功，即历史上已经执行过与该第一交易请求相同的业务，可以从交易执行表中获取与目标数据实体标识、目标请求方信息和目标传参哈希值关联存储的目标交易执行结果和目标交易哈希值；反之，则判定为匹配失败，即历史上尚未执行过与该第一交易请求相同的业务。In some other embodiments, if the transaction execution table records the data entity identifier, requester information, reference hash value, transaction execution result and transaction hash value of the transaction request executed successfully in history, the data entity identifier is Generated according to the business party ID and the platform party ID of the successful transaction request, for example, cascading the business party ID and the platform party ID to generate the data entity ID, or calculating the hash of the business party ID and the platform party ID Value, to obtain the data entity ID, which is not limited in this disclosure, then the node device can assign a first platform party ID to the operation object targeted by the first transaction request according to the first business party ID, and then the node device can according to The first business party platform and the first platform party ID generate the first data entity ID, and the method of generating the first data entity ID is not limited, as long as the operation object targeted by the first transaction request can be uniquely distinguished. Then, the node device can combine the first data entity identifier of the first transaction request, the information of the first requester, and the first reference hash value calculated by the above steps with the data entity of each transaction request already recorded in the transaction execution table. ID, requester information and the passed parameter hash value are compared to check whether the data entity ID in the transaction execution table has the same target data entity ID as the first data entity ID, and check whether the requester information in the transaction execution table has the same target data entity ID as For the target requester information that is the same as the first requester information, query whether the passed parameter hash value in the transaction execution table has the same target passed parameter hash value as the first passed parameter hash value, if there is a one-to-one matching The target data entity identifier, target requester information and target parameter hash value are determined to match successfully, that is, the same business as the first transaction request has been executed in history, and the target data entity can be obtained from the transaction execution table. The target transaction execution result and target transaction hash value stored in association with the identification, target requester information, and target parameter hash value; otherwise, it is determined that the matching fails, that is, the same business as the first transaction request has not been executed in history .

本公开实施例中，数据实体可以理解为数据集中一类数据对象的个体，比如可以是具体的人、事、物，也可以为抽象的概念、联系等，数据实体标识可以用于唯一区分各个数据实体。In the embodiments of the present disclosure, a data entity can be understood as an individual of a type of data object in a data set, such as a specific person, thing, thing, or an abstract concept, connection, etc., and the data entity identifier can be used to uniquely distinguish each data entity.

本公开实施例中，历史上已经执行过与该第一交易请求相同的业务是指，在第一交易请求之前，已经执行过与该第一交易请求所针对的操作对象相同、且针对该操作对象所执行的交易操作也相同的交易请求，同时该之前成功执行的交易请求也是由该第一交易请求的发起者(第一请求方)发起，即该之前成功执行的交易请求的数据实体标识与第一数据实体标识相同，请求方信息与该第一请求方信息相同，传入参数和该第一传入参数(这里是通过判断传参哈希值与该第一传参哈希值相同来确定的)，当上述三个参数存在任意一个不一致时，则可以确定历史上尚未执行过与该第一交易请求相同的业务。通过在交易执行表中关联记录已经成功执行的交易的数据实体标识、请求方信息和传参哈希值，一方面，可以针对相同业务的多笔交易请求区分出来，满足幂等性要求，防止同一笔业务被重复执行，保证交易执行的安全性和可靠性；另一方面，通过业务方标识和平台方标识来生成交易请求所针对的操作对象的数据实体标识，即由多方来维护操作对象的唯一标识，而不是单纯由业务方来维护，可以进一步确定不同交易请求所针对的是同一操作对象，进一步保证交易执行的安全性和可靠性。In the embodiments of the present disclosure, the same business as the first transaction request has been executed in history means that, before the first transaction request, the same operation object as the first transaction request has been executed, and for the operation The transaction operation performed by the object is also the same as the transaction request, and the transaction request that was successfully executed before is also initiated by the initiator of the first transaction request (the first requester), that is, the data entity identifier of the transaction request that was successfully executed before The same as the first data entity identifier, the requester information is the same as the first requester information, the incoming parameter and the first incoming parameter (here, by judging that the passed parameter hash value is the same as the first passed parameter hash value determined), when any one of the above three parameters is inconsistent, it can be determined that the same business as the first transaction request has not been executed in history. By associating and recording the data entity identifier, requester information and parameter hash value of the transaction that has been successfully executed in the transaction execution table, on the one hand, multiple transaction requests for the same business can be distinguished to meet the requirements of idempotence and prevent The same business is executed repeatedly to ensure the security and reliability of transaction execution; on the other hand, the data entity identification of the operation object targeted by the transaction request is generated through the business party ID and the platform party ID, that is, the operation object is maintained by multiple parties Instead of simply being maintained by the business side, it can be further determined that different transaction requests are aimed at the same operation object, further ensuring the security and reliability of transaction execution.

在再一些实施例中，若交易执行表中记录了历史上执行成功的交易请求的交易执行表唯一键、交易执行结果和交易哈希值，每个交易执行表唯一键是根据对应交易请求的数据实体标识、请求方信息和传参哈希值生成的，以用于唯一区别针对同一数据实体标识所对应的操作对象进行的相同的交易操作，且该相同的交易操作是同一请求方发起的。节点设备可以根据第一交易请求的第一数据实体标识、第一请求方信息和第一传参哈希值生成第一交易执行表唯一键。然后，节点设备可以将第一交易请求的第一交易执行表唯一键与交易执行表中已经记录的各个交易请求的交易执行表唯一键进行比较，查询交易执行表中的交易执行表唯一键是否存在与第一交易执行表唯一键相同的目标交易执行表唯一键，若存在与之匹配的目标交易执行表唯一键，则判定为匹配成功，即历史上已经执行过与该第一交易请求相同的业务，可以从交易执行表中获取与目标交易执行表唯一键关联存储的目标交易执行结果和目标交易哈希值；反之，则判定为匹配失败，即历史上尚未执行过与该第一交易请求相同的业务。In some further embodiments, if the transaction execution table records the transaction execution table unique key, transaction execution result and transaction hash value of the transaction request successfully executed in history, each transaction execution table unique key is based on the corresponding transaction request Generated by the data entity ID, requester information and parameter hash value to uniquely distinguish the same transaction operation performed on the operation object corresponding to the same data entity ID, and the same transaction operation is initiated by the same requester . The node device may generate the unique key of the first transaction execution table according to the first data entity identifier of the first transaction request, the first requester information and the hash value of the first passed parameter. Then, the node device can compare the unique key of the first transaction execution table of the first transaction request with the unique key of the transaction execution table of each transaction request recorded in the transaction execution table, and query whether the unique key of the transaction execution table in the transaction execution table There is a unique key in the target transaction execution table that is the same as the unique key in the first transaction execution table. If there is a matching unique key in the target transaction execution table, it is determined that the match is successful, that is, the same request as the first transaction request has been executed in history. For the business, the target transaction execution result and the target transaction hash value stored in association with the unique key of the target transaction execution table can be obtained from the transaction execution table; otherwise, it is determined that the matching fails, that is, the first transaction has not been executed in history Ask for the same business.

本公开实施例中，历史上已经执行过与该第一交易请求相同的业务是指，在第一交易请求之前，已经执行过与该第一交易请求所针对的操作对象相同、且针对该操作对象所执行的交易操作也相同的交易请求，同时该之前成功执行的交易请求也是由该第一交易请求的发起者(第一请求方)发起，即该之前成功执行的交易请求中存在交易执行表唯一键与第一交易执行表唯一键相同的目标交易执行表唯一键，当不存在与之匹配的目标交易执行表唯一键时，则可以确定历史上尚未执行过与该第一交易请求相同的业务。通过在交易执行表中关联记录已经成功执行的交易的交易执行表唯一键，一方面，可以针对相同业务的多笔交易请求区分出来，满足幂等性要求，防止同一笔业务被重复执行，保证交易执行的安全性和可靠性；另一方面，通过交易执行表唯一键来唯一标记由某一请求方发起的针对某一操作对象的交易操作，该交易执行表唯一键根据对应的数据实体标识、请求方信息和传参哈希值来对应生成，即由多方来维护交易请求的发起者针对操作对象的交易操作的唯一标识，而不是单纯由业务方来维护，可以进一步确定不同交易请求是由相同发起者发起的针对同一操作对象的同一交易操作，进一步保证交易执行的安全性和可靠性。In the embodiments of the present disclosure, the same business as the first transaction request has been executed in history means that, before the first transaction request, the same operation object as the first transaction request has been executed, and for the operation The transaction operation performed by the object is also the same as the transaction request, and the transaction request that was successfully executed before is also initiated by the initiator of the first transaction request (the first requester), that is, there is a transaction execution in the transaction request that was successfully executed before The unique key of the target transaction execution table whose unique key is the same as the unique key of the first transaction execution table. When there is no matching unique key of the target transaction execution table, it can be determined that the same transaction request as the first transaction request has not been executed in history. Business. By associating and recording the unique key of the transaction execution table that has been successfully executed in the transaction execution table, on the one hand, multiple transaction requests for the same business can be distinguished, meeting the idempotence requirements, preventing the same business from being executed repeatedly, and ensuring The security and reliability of transaction execution; on the other hand, the transaction operation initiated by a certain requester for a certain operation object is uniquely marked by the unique key of the transaction execution table. The unique key of the transaction execution table is identified according to the corresponding data entity , the requester information and the passed parameter hash value to generate correspondingly, that is, the initiator of the transaction request maintains the unique identifier of the transaction operation of the operation object by multiple parties, instead of simply being maintained by the business party, which can further determine whether different transaction requests are The same transaction operation for the same operation object initiated by the same initiator further guarantees the security and reliability of transaction execution.

在步骤S540中，将所述交易执行表中与所述第一业务方标识、所述第一请求方信息和所述第一传参哈希值匹配的目标交易执行结果和目标交易哈希值返回至所述第一请求方的终端设备，所述目标交易哈希值与所述第一交易请求的第一交易哈希值不同。In step S540, the target transaction execution result and the target transaction hash value matched with the first business party identifier, the first requester information and the first parameter hash value in the transaction execution table Returning to the terminal device of the first requesting party, the target transaction hash value is different from the first transaction hash value of the first transaction request.

本公开实施例中，若交易执行表中存在与第一交易请求的第一业务方标识、第一请求方信息和第一传参哈希值匹配的目标交易执行结果和目标交易哈希值，则节点设备可以判定之前已经成功执行过与第一交易请求相同的业务，此时，节点设备可以直接将交易执行表中存储的与之对应的目标交易执行结果和目标交易哈希值返回给第一请求方的终端设备，而不会再重复执行该第一交易请求，第一请求方的终端接收到节点设备返回的目标交易哈希值和目标交易执行结果之后，将接收到的目标交易哈希值与在第一请求方的终端设备上生成的第一交易哈希值进行比较，判定目标交易哈希值与第一交易哈希值不同，则可以获知虽然接收到了目标交易执行结果，但该目标交易执行结果不是执行第一交易请求获得的，而是之前已经成功执行的交易请求获得的。In the embodiment of the present disclosure, if there is a target transaction execution result and a target transaction hash value that match the first transaction request's first business party ID, first requester information, and first parameter hash value in the transaction execution table, Then the node device can determine that the same business as the first transaction request has been successfully executed before, and at this time, the node device can directly return the corresponding target transaction execution result and target transaction hash value stored in the transaction execution table to the first transaction request. A requester’s terminal device will not repeat the first transaction request. After the first requester’s terminal receives the target transaction hash value and target transaction execution result returned by the node device, it will receive the target transaction hash value The hash value is compared with the first transaction hash value generated on the terminal device of the first requester, and it is determined that the target transaction hash value is different from the first transaction hash value, and it can be known that although the target transaction execution result has been received, the The target transaction execution result is not obtained by executing the first transaction request, but obtained by a transaction request that has been successfully executed before.

其中，第一交易哈希值是第一请求方的终端设备在生成第一交易请求之后，对第一交易请求进行哈希运算获得的。Wherein, the first transaction hash value is obtained by performing a hash operation on the first transaction request after the terminal device of the first requester generates the first transaction request.

本公开实施例中，节点设备101可接收各个终端设备所发送的交易请求，其中包括第一终端201所发送的第一交易请求，将所接收到的交易请求确定为待上链的交易数据，将待上链的多个交易数据存储至交易池中，并按照一定的顺序从交易池中读取目标交易数据。其中，目标交易数据可以是指上述多个交易数据中的任一交易数据，这里假设目标交易数据包括上述第一交易请求。目标交易数据包括但不限于电子资源转移的交易数据、股权交易数据以及基金交易数据等。此处顺序可包括交易数据被缓存于交易池的时间顺序、交易数据的重要性优先级、交易类型等，这样有利于有序地对各个交易数据进行验证，提高验证的灵活性和准确度。In the embodiment of the present disclosure, thenode device 101 can receive transaction requests sent by each terminal device, including the first transaction request sent by the first terminal 201, and determine the received transaction request as the transaction data to be uploaded, Store multiple transaction data to be chained in the transaction pool, and read the target transaction data from the transaction pool in a certain order. Wherein, the target transaction data may refer to any transaction data among the above-mentioned plurality of transaction data, and here it is assumed that the target transaction data includes the above-mentioned first transaction request. Target transaction data includes, but is not limited to, electronic resource transfer transaction data, equity transaction data, and fund transaction data. The order here may include the time sequence in which the transaction data is cached in the transaction pool, the importance priority of the transaction data, the transaction type, etc., which is conducive to orderly verification of each transaction data and improves the flexibility and accuracy of verification.

在一些实施例中，交易类型可以包括实时性交易类型和非实时性交易类型，实时性交易类型可包括电子资源转移(实时到账)、上链电子证件等等；非实时性交易类型可包括上链新闻数据、用户注册数据等等。节点设备101可以优先读取实时性交易类型的交易数据，然后读取非实时性交易类型的交易数据，这样可以确保实时性交易类型的交易数据能够被实时处理。In some embodiments, transaction types can include real-time transaction types and non-real-time transaction types, and real-time transaction types can include electronic resource transfer (real-time account), electronic certificates on the chain, etc.; non-real-time transaction types can include On-chain news data, user registration data, etc. Thenode device 101 may read the transaction data of the real-time transaction type first, and then read the transaction data of the non-real-time transaction type, so as to ensure that the transaction data of the real-time transaction type can be processed in real time.

在一些实施例中，重要性优先级可以是根据交易数据所属的机构确定的，例如，该交易数据属于行政部门，则该交易数据的重要性优先级比较高；反之，如果该交易数据属于企业或个人，则该交易数据的重要性优先级比较低。重要性优先级用于指示交易数据的重要性、私密性等等，即重要性优先级越高，交易数据的重要性、私密性越高；重要性优先级越低，交易数据的重要性、私密性越低。因此，节点设备101可以优先读取重要性优先级高的交易数据，然后读取重要性优先级低的交易数据，这样确保重要性优先级高的交易数据能够被实时处理，可有效提高交易数据的安全性，避免重要性优先级高的交易数据被泄露。In some embodiments, the importance priority can be determined according to the institution to which the transaction data belongs. For example, if the transaction data belongs to the administrative department, the priority of the transaction data is relatively high; on the contrary, if the transaction data belongs to the enterprise or individuals, the priority of the transaction data is relatively low. The importance priority is used to indicate the importance, privacy, etc. of the transaction data, that is, the higher the importance priority, the higher the importance and privacy of the transaction data; the lower the importance priority, the higher the importance and privacy of the transaction data. The less privacy. Therefore, thenode device 101 can preferentially read the transaction data with high importance priority, and then read the transaction data with low priority priority, so as to ensure that the transaction data with high priority priority can be processed in real time, which can effectively improve the transaction data The security of the transaction data with high importance and priority is avoided from being leaked.

在一些实施例中，节点设备101可以按照交易池中各个交易数据被接收到的时间由先到后的顺序，依次读取各个交易数据，这样可以提高对各个交易数据处理的公平性。In some embodiments, thenode device 101 may sequentially read each transaction data according to the time at which each transaction data is received in the transaction pool, which can improve the fairness of processing each transaction data.

节点设备接收到第一终端201发送的第一交易请求，可以获取该第一交易请求的属性信息，根据该第一交易请求的属性信息验证该第一交易请求的有效性。具体的，验证第一交易请求的有效性可以是指：验证该第一交易请求是否能够被成功执行；如果能够被成功执行，确定该第一交易请求具有有效性；如果不能被成功执行，则确定该第一交易请求不具有有效性。After receiving the first transaction request sent by the first terminal 201, the node device may acquire attribute information of the first transaction request, and verify the validity of the first transaction request according to the attribute information of the first transaction request. Specifically, verifying the validity of the first transaction request may refer to: verifying whether the first transaction request can be successfully executed; if it can be successfully executed, determining that the first transaction request is valid; It is determined that the first transaction request is not valid.

在读取到第一交易请求后，可获取第一交易请求的属性信息，此处属性信息包括为预测执行第一交易请求所需要电子资源的第一数量、第一交易请求的大小、第一交易请求的签名信息、第一交易请求的生成时间等。即第一数量可以是指用户愿意为执行第一交易请求所支付的电子资源的数量。其中，电子资源是指用于购买数字资产的资金，此处的数字资产可包括但不限于：电子票据、游戏资源(如游戏币、游戏装备等)，等等。After the first transaction request is read, the attribute information of the first transaction request can be obtained, where the attribute information includes the first quantity of electronic resources required for predicting the execution of the first transaction request, the size of the first transaction request, the first The signature information of the transaction request, the generation time of the first transaction request, etc. That is, the first amount may refer to the amount of electronic resources that the user is willing to pay for executing the first transaction request. Wherein, electronic resources refer to funds used to purchase digital assets, where digital assets may include but not limited to: electronic bills, game resources (such as game currency, game equipment, etc.), and so on.

从交易池中读取第一交易请求之后，获取用户为预测执行第一交易请求所需要电子资源的第一数量，然后再获取预先存储的实际执行该第一交易请求所需要的电子资源的第二数量，将该第一数量与该第二数量进行对比，若该第一数量大于该第二数量，则确定该第一交易请求具有有效性，即说明用户预测执行第一交易请求所需要的电子资源大于实际执行第一交易请求所需要的电子资源，则第一交易请求执行能成功；若该第一数量小于或等于第二数量，则确定该第一交易请求不具有有效性，即说明用户预测执行第一交易请求所需要的电子资源小于或等于实际执行第一交易请求所需要的电子资源，则第一交易请求执行不能成功，第一交易请求就会执行失败。After reading the first transaction request from the transaction pool, obtain the first amount of electronic resources required by the user to predict the execution of the first transaction request, and then obtain the pre-stored number of electronic resources required for actually executing the first transaction request. Two quantities, compare the first quantity with the second quantity, if the first quantity is greater than the second quantity, it is determined that the first transaction request is valid, that is to say, the user predicts that the first transaction request needs to be executed If the electronic resources are greater than the electronic resources required to actually execute the first transaction request, the first transaction request can be executed successfully; if the first quantity is less than or equal to the second quantity, it is determined that the first transaction request is not valid, that is, If the user predicts that the electronic resources required to execute the first transaction request are less than or equal to the electronic resources actually required to execute the first transaction request, then the execution of the first transaction request cannot be successfully executed, and the execution of the first transaction request will fail.

在一些实施例中，将该第一交易请求的大小与预先设定的交易数据的大小对应的阈值进行比对，若该第一交易请求的大小大于该交易数据的大小对应的阈值，表明第一交易请求中存在冗余数据，第一交易请求的大小不满足条件，则确定该第一交易请求不具有有效性。若该第一交易请求的大小小于或等于该交易数据的大小对应的阈值，表明第一交易请求中不存在冗余数据，则确定该第一交易请求具有有效性。In some embodiments, the size of the first transaction request is compared with a preset threshold corresponding to the size of transaction data, and if the size of the first transaction request is greater than the threshold corresponding to the size of the transaction data, it indicates that the first There is redundant data in a transaction request, and the size of the first transaction request does not satisfy the condition, then it is determined that the first transaction request is not valid. If the size of the first transaction request is less than or equal to the threshold corresponding to the size of the transaction data, indicating that there is no redundant data in the first transaction request, it is determined that the first transaction request is valid.

在一些实施例中，验证该第一交易请求是否具有有效性可以是指：验证第一交易请求的真实性、完整性(即是否被篡改)，如果该第一交易请求是真实的、完整的(即没有被篡改)，则确定该第一交易请求具有有效性；如果该第一交易请求是不真实的、不完整的(即被篡改)，则确定该第一交易请求不具有有效性。In some embodiments, verifying whether the first transaction request is valid may refer to: verifying the authenticity and integrity of the first transaction request (that is, whether it has been tampered with), if the first transaction request is true and complete (that is, not tampered with), then determine that the first transaction request is valid; if the first transaction request is untrue and incomplete (that is, tampered with), then determine that the first transaction request is not valid.

在一些实施例中，节点设备101可获取该第一交易请求对应的公钥，该第一交易请求对应的公钥可以是指上传该第一交易请求的第一终端201的公钥。可根据该第一交易请求对应的公钥对该签名信息进行验证，若验证通过，表明该第一交易请求未被篡改，具有完整性，则确定该第一交易请求具有有效性，若验证未通过，表明该第一交易请求被篡改，不具有完整性，则确定该第一交易请求不具有有效性。In some embodiments, thenode device 101 may obtain the public key corresponding to the first transaction request, and the public key corresponding to the first transaction request may refer to the public key of the first terminal 201 that uploaded the first transaction request. The signature information can be verified according to the public key corresponding to the first transaction request. If the verification is passed, it indicates that the first transaction request has not been tampered with and has integrity, and it is determined that the first transaction request is valid. If the verification is not If the pass indicates that the first transaction request has been tampered with and has no integrity, then it is determined that the first transaction request is not valid.

具体的，在第一交易请求未被上传至节点设备101时，第一终端201可对第一交易请求进行哈希运算，得到第一交易请求的第一交易哈希值，采用私钥对第一交易请求的哈希值进行加密，得到携带第一终端201的签名的第一交易请求，将该第一交易请求和携带终端的签名的第一交易请求一起发送至区块链网络的节点设备101。Specifically, when the first transaction request has not been uploaded to thenode device 101, the first terminal 201 can perform a hash operation on the first transaction request to obtain the first transaction hash value of the first transaction request, and use the private key to Encrypt the hash value of a transaction request to obtain the first transaction request carrying the signature of the first terminal 201, and send the first transaction request and the first transaction request carrying the signature of the terminal to the node device of theblockchain network 101.

相应地，节点设备可以接收第一终端201所发送的该第一交易请求、携带第一终端201的签名的第一交易请求，节点设备可以获取第一终端201的公钥，将该公钥作为该第一交易请求对应的公钥。节点设备对第一交易请求进行哈希运算，得到第一交易哈希值，采用公钥对携带第一终端201的签名的第一交易请求进行解密，得到第三交易哈希值，将第一交易哈希值与第三交易哈希值进行比对，若第一哈希值与第三哈希值不相同，则表明第一交易请求不具有完整性，即第一交易请求被篡改，确定第一交易请求未被验证通过；若第一哈希值与第三哈希值相同，则表明该第一交易请求具有完整性，该第一交易请求未被篡改，确定第一交易请求验证通过。Correspondingly, the node device may receive the first transaction request sent by the first terminal 201 and the first transaction request carrying the signature of the first terminal 201, the node device may obtain the public key of the first terminal 201, and use the public key as The public key corresponding to the first transaction request. The node device performs hash operation on the first transaction request to obtain the first transaction hash value, uses the public key to decrypt the first transaction request carrying the signature of the first terminal 201, obtains the third transaction hash value, and converts the first The transaction hash value is compared with the third transaction hash value. If the first hash value is different from the third hash value, it indicates that the first transaction request does not have integrity, that is, the first transaction request has been tampered with. The first transaction request has not been verified; if the first hash value is the same as the third hash value, it indicates that the first transaction request has integrity, the first transaction request has not been tampered with, and it is determined that the first transaction request has passed the verification .

其中，属性信息中的为预测执行第一交易请求所需要电子资源的第一数量、第一交易请求的生成时间，可用于验证第一交易请求是否能够被成功执行；属性信息中的第一交易请求的大小、第一交易请求的签名信息，用于验证第一交易请求的真实性、完整性(即是否被篡改)。Among them, in the attribute information, the first quantity of electronic resources needed to predict the execution of the first transaction request and the generation time of the first transaction request can be used to verify whether the first transaction request can be successfully executed; the first transaction in the attribute information The size of the request and the signature information of the first transaction request are used to verify the authenticity and integrity of the first transaction request (that is, whether it has been tampered with).

本公开实施例中，若第一交易请求具有有效性，则可以进一步验证第一交易请求是否具有合法性。其中，可以获取该区块链网络中确定该第一交易请求具有有效性的节点设备的数量；若所获取到的数量大于数量阈值(该数量阈值可以根据实际需求进行设置，本公开对此不做限定)，则确定该第一交易请求具有合法性；若所获取到的数量小于或等于该数量阈值，则确定该第一交易请求不具有合法性。In the embodiment of the present disclosure, if the first transaction request is valid, it may be further verified whether the first transaction request is legal. Among them, the number of node devices in the block chain network that determines that the first transaction request is valid can be obtained; if the obtained number is greater than the number threshold (the number threshold can be set according to actual needs, this disclosure does not limit), then it is determined that the first transaction request is legal; if the obtained quantity is less than or equal to the quantity threshold, it is determined that the first transaction request is not legal.

需要说明的是，如果交易池中的交易数据被读取后，可以将被读取的交易数据从交易池中删除，以节省存储空间，可有效存储更多新的交易数据。It should be noted that if the transaction data in the transaction pool is read, the read transaction data can be deleted from the transaction pool to save storage space and effectively store more new transaction data.

如果该第一交易请求具有有效性和合法性，表明该第一交易请求具有完整性、真实性、或者能够被成功执行，且确定该第一交易请求具有有效性的节点设备的数量大于数量阈值，因此，节点设备101可将第一交易请求作为目标交易数据存储至区块链网络的区块(这里称之为第一区块)中。If the first transaction request is valid and legal, it indicates that the first transaction request has integrity, authenticity, or can be successfully executed, and the number of node devices that determine that the first transaction request is valid is greater than the number threshold , therefore, thenode device 101 may store the first transaction request as the target transaction data in a block (herein referred to as the first block) of the blockchain network.

例如，假设节点设备101将第一交易请求存储至区块10001中，区块10001中包括区块头和区块体，区块10001的区块头中包括10000H、10001H、10001T等，其中，10000H代表区块链中区块10000的区块头哈希值，10001H代表区块10001的区块体中交易数据(包括第一交易请求，还可以包括其它交易数据)所对应的哈希值，10001T代表区块10001的区块生成时间戳。For example, assume thatnode device 101 stores the first transaction request in block 10001. Block 10001 includes a block header and a block body. The block header of block 10001 includes 10000H, 10001H, 10001T, etc., where 10000H represents the block The block header hash value of block 10000 in the block chain, 10001H represents the hash value corresponding to the transaction data (including the first transaction request, and other transaction data) in the block body of block 10001, and 10001T represents the block The block generation timestamp of 10001.

在示例性实施例中，所述方法还可以包括：若所述第一交易请求不具有合法性，或者所述第一区块上链失败，则向所述第一请求方的终端设备返回执行所述第一交易请求失败的第一交易执行结果。In an exemplary embodiment, the method may further include: if the first transaction request is not legal, or if the first block chaining fails, returning execution to the terminal device of the first requesting party The first transaction execution result of the failure of the first transaction request.

如果第一交易请求不具有有效性和合法性，表明该第一交易请求不具有完整性、真实性或者不能够被成功执行，或者确定该第一交易请求具有有效性的节点设备的数量小于或等于数量阈值，因此，节点设备101可对第一交易请求进行回滚，可避免将无效的交易数据存储至区块中，有利于节省区块的存储空间，从而保证了区块链中数据的有效性。回滚指的是程序或数据处理错误，将程序或数据恢复到上一次正确状态的行为。If the first transaction request does not have validity and legality, it indicates that the first transaction request does not have integrity, authenticity or cannot be successfully executed, or the number of node devices that determine that the first transaction request is valid is less than or equal to the quantity threshold, therefore, thenode device 101 can roll back the first transaction request, which can avoid storing invalid transaction data in the block, which is beneficial to save the storage space of the block, thus ensuring the data security in the block chain effectiveness. Rollback refers to the act of restoring a program or data to its last correct state after a program or data processing error.

若被读取的交易数据不具有有效性或者合法性，则从该交易池中移除该被读取的交易数据。If the read transaction data is not valid or legal, the read transaction data is removed from the transaction pool.

本公开实施方式提供的基于区块链的数据处理方法，一方面，通过在区块链网络中部署用于维护交易执行表的智能合约，当区块链网络中的节点设备接收到第一请求方的终端设备发送的第一交易请求时，可以根据第一交易请求携带的第一业务方标识、第一请求方信息和用于执行第一交易请求的第一传入参数查询智能合约维护的交易执行表，若判定交易执行表与第一传入参数的第一传参哈希值、第一业务方标识和第一请求方信息匹配，则节点设备可以确定与该第一交易请求相同的业务在此之前已经被成功执行过，此时，节点设备不执行该第一交易请求，而是将交易执行表中所述第一业务方标识、第一请求方信息和第一传参哈希值匹配的目标交易执行结果和目标交易哈希值直接返回至第一请求方的终端设备，从而可以避免节点设备重复执行相同的业务，确保针对相同业务的交易操作不会被重复执行，确保业务执行的幂等性，即通过智能合约维护的交易执行表可以保证存在多笔相同业务提交的多笔不同交易请求并发提交时，也只有一笔业务能够执行成功。另一方面，接收到目标交易执行结果和目标交易哈希值的第一请求方的终端设备，可以通过判定目标交易哈希值与第一交易请求的第一交易哈希值不同来获知与该第一交易请求相同的业务之前已经被成功执行过。The blockchain-based data processing method provided by the embodiments of the present disclosure, on the one hand, by deploying the smart contract for maintaining the transaction execution table in the blockchain network, when the node device in the blockchain network receives the first request When the first transaction request is sent by the party’s terminal device, it can query the smart contract maintained Transaction execution table, if it is determined that the transaction execution table matches the first parameter hash value of the first incoming parameter, the first business party ID and the first requester information, the node device can determine the same transaction request as the first transaction request The business has been successfully executed before, at this time, the node device does not execute the first transaction request, but hashes the first business party ID, first requester information, and first passed parameters in the transaction execution table The execution result of the target transaction and the hash value of the target transaction that match the value are directly returned to the terminal device of the first requesting party, thereby avoiding repeated execution of the same business by the node device, ensuring that the transaction operation for the same business will not be executed repeatedly, and ensuring that the business The idempotence of execution, that is, the transaction execution table maintained by the smart contract can guarantee that when there are multiple different transaction requests submitted by the same business and submitted concurrently, only one business can be executed successfully. On the other hand, the terminal device of the first requesting party that receives the target transaction execution result and the target transaction hash value can know that the target transaction hash value is different from the first transaction hash value of the first transaction request. The first transaction requests the same business which has been successfully executed before.

图6示意性示出了根据本公开的另一个实施例的基于区块链的数据处理方法的流程图。图6实施例提供的方法与上述图5实施例提供的方法之间的区别在于，在上述步骤S510之前，即在获取第一请求方的终端设备发送的第一交易请求之前，所述方法还可以进一步包括以下步骤。Fig. 6 schematically shows a flow chart of a blockchain-based data processing method according to another embodiment of the present disclosure. The difference between the method provided by the embodiment of FIG. 6 and the method provided by the embodiment of FIG. 5 above is that before the above step S510, that is, before obtaining the first transaction request sent by the terminal device of the first requesting party, the method also The following steps may be further included.

节点设备可以在接收到第一终端201发送的第一交易请求之前，已经接收到该第一终端201发送的第二交易请求，且该第二交易请求与第一交易请求携带相同的第一业务方标识、第一请求方信息和第一传入参数，即第一交易请求和第二交易请求是该同一第一请求方先后发起的针对同一业务的相同交易操作。The node device may have received the second transaction request sent by the first terminal 201 before receiving the first transaction request sent by the first terminal 201, and the second transaction request and the first transaction request carry the same first service The party identifier, the first requester information and the first incoming parameters, that is, the first transaction request and the second transaction request are the same transaction operations for the same business initiated successively by the same first requester.

在步骤S620中，调用所述智能合约计算生成所述第一传入参数的第一传参哈希值。In step S620, the smart contract is invoked to calculate and generate a first hash value of the first incoming parameter.

节点设备接收到第二交易请求之后，会利用哈希函数生成第二交易请求携带的第一传入参数的第一传参哈希值。After receiving the second transaction request, the node device will use a hash function to generate a first passed parameter hash value of the first passed parameter carried in the second transaction request.

在步骤S630中，调用所述智能合约将所述第一业务方标识、所述第一请求方信息和所述第一传参哈希值与所述交易执行表匹配。In step S630, the smart contract is invoked to match the first business party identifier, the first requester information and the first passed parameter hash value with the transaction execution table.

节点设备接收到第二交易请求之后，会将第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值与交易执行表进行匹配。具体的匹配方式可以参照上述节点设备将第一交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值与交易执行表进行匹配。After the node device receives the second transaction request, it will match the first business party identifier, first requester information, and first parameter hash value carried in the second transaction request with the transaction execution table. For a specific matching method, refer to the above-mentioned node device to match the first business party identifier, first requester information, and first parameter hash value carried in the first transaction request with the transaction execution table.

在步骤S640中，若所述交易执行表与所述第一业务方标识、所述第一请求方信息和所述第一传参哈希值不匹配，则调用所述智能合约获取所述第二交易请求的第二交易执行结果。In step S640, if the transaction execution table does not match the first business party identifier, the first requester information, and the first parameter hash value, call the smart contract to obtain the first The second transaction execution result of the second transaction request.

本公开实施例中，若交易执行表与第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值匹配，则类似于上述第一交易请求，说明在第二交易请求之前，已经执行过与第二交易请求相同的业务，此时可以直接返回历史上成功执行的与第二交易请求相同的业务的目标交易执行结果和目标交易哈希值，而不需要执行第二交易请求。In the embodiment of the present disclosure, if the transaction execution table matches the first business party ID, first requester information, and first parameter hash value carried in the second transaction request, similar to the above-mentioned first transaction request, the description in Before the second transaction request, the same business as the second transaction request has been executed. At this time, the target transaction execution result and target transaction hash value of the same business as the second transaction request successfully executed in history can be directly returned without the need Execute the second transaction request.

在一些实施例中，交易执行表与第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值不匹配，可以是交易执行表中不存在与第二交易请求携带的第一业务方标识匹配的目标业务方标识，或者交易执行表中不存在与第二交易请求携带的第一请求方信息匹配的目标请求方信息，或者交易执行表中不存在与第二交易请求携带的第一传参哈希值匹配的目标传参哈希值。In some embodiments, the transaction execution table does not match the first business party ID, first requester information, and first parameter hash value carried in the second transaction request. It may be that the transaction execution table does not exist in the second transaction The first business party ID carried in the request matches the target business party ID, or there is no target requester information matching the first requester information carried in the second transaction request in the transaction execution table, or the transaction execution table does not exist in the transaction execution table. The target parameter hash value that matches the first parameter hash value carried in the second transaction request.

在另一些实施例中，节点设备可以根据第二交易请求携带的第一业务方标识生成第一平台方标识，交易执行表与第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值不匹配，可以是交易执行表中不存在与第二交易请求携带的第一业务方标识匹配的目标业务方标识，或者交易执行表中不存在与第一平台方标识匹配的目标平台方标识，或者交易执行表中不存在与第二交易请求携带的第一请求方信息匹配的目标请求方信息，或者交易执行表中不存在与第二交易请求携带的第一传参哈希值匹配的目标传参哈希值。In some other embodiments, the node device may generate the first platform party ID according to the first business party ID carried in the second transaction request, and the transaction execution table and the first business party ID and first requester information carried in the second transaction request If the hash value of the first passed parameter does not match, it may be that there is no target business party ID matching the first business party ID carried in the second transaction request in the transaction execution table, or there is no target business party ID matching the first platform party ID in the transaction execution table. ID matching target platform party ID, or there is no target requester information matching the first requester information carried in the second transaction request in the transaction execution table, or the first requester information carried in the second transaction request does not exist in the transaction execution table The target parameterized hash value that the parameterized hash value matches.

在又一些实施例中，节点设备可以根据第二交易请求携带的第一业务方标识生成第一平台方标识，再根据第一业务方标识和第一平台方标识生成第一数据实体标识，交易执行表与第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值不匹配，可以是交易执行表中不存在与第二交易请求的第一数据实体标识匹配的目标数据实体标识，或者交易执行表中不存在与第二交易请求携带的第一请求方信息匹配的目标请求方信息，或者交易执行表中不存在与第二交易请求携带的第一传参哈希值匹配的目标传参哈希值。In some other embodiments, the node device may generate the first platform party ID according to the first business party ID carried in the second transaction request, and then generate the first data entity ID according to the first business party ID and the first platform party ID, and the transaction The execution table does not match the first business party ID, the first requester information, and the first parameter hash value carried in the second transaction request. It may be that the first data entity ID of the second transaction request does not exist in the transaction execution table. Matching target data entity identifier, or there is no target requestor information matching the first requestor information carried in the second transaction request in the transaction execution table, or the first requestor information carried in the second transaction request does not exist in the transaction execution table The hash value of the target passed parameter that the parameter hash value matches.

在再一些实施例中，节点设备可以根据第二交易请求携带的第一业务方标识生成第一平台方标识，再根据第一业务方标识和第一平台方标识生成第一数据实体标识，再根据第一数据实体标识、第一请求方信息和第一传参哈希值生成第一交易执行表唯一键，交易执行表与第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值不匹配，可以是交易执行表中不存在与第二交易请求的第一交易执行表唯一键匹配的目标交易执行表唯一键。In some other embodiments, the node device may generate the first platform party ID according to the first business party ID carried in the second transaction request, and then generate the first data entity ID according to the first business party ID and the first platform party ID, and then Generate the unique key of the first transaction execution table according to the first data entity identifier, the first requester information and the first parameter hash value, and the transaction execution table and the first business party identifier and first requester information carried in the second transaction request If the hash value of the first passed parameter does not match, it may be that there is no unique key of the target transaction execution table matching the unique key of the first transaction execution table of the second transaction request in the transaction execution table.

在示例性实施例中，调用所述智能合约获取所述第二交易请求的第二交易执行结果，可包括：验证所述第二交易请求的合法性；若所述第二交易请求具有合法性，则生成包括所述第二交易请求的第二区块；将所述第二区块添加至对应的区块链；若所述第二区块上链成功，则调用所述智能合约执行所述第二交易请求；若成功执行所述第二交易请求，则所述第二交易执行结果为成功执行所述第二交易请求。In an exemplary embodiment, calling the smart contract to obtain the second transaction execution result of the second transaction request may include: verifying the legitimacy of the second transaction request; if the second transaction request is legal , then generate a second block including the second transaction request; add the second block to the corresponding block chain; if the second block is successfully linked, call the smart contract to execute the The second transaction request; if the second transaction request is successfully executed, the second transaction execution result is the successful execution of the second transaction request.

第二交易请求的合法性的验证方式可以参照上述第一交易请求的合法性的验证过程。For the method of verifying the legitimacy of the second transaction request, refer to the process of verifying the legitimacy of the first transaction request above.

需要说明的是，虽然本公开实施例以先将具有合法性的交易请求(包括第一交易请求和第二交易请求)上链，然后由节点设备调用智能合约执行上链后的交易请求获得交易执行结果(包括第一交易执行结果、第二交易执行结果和目标交易执行结果)为例进行举例说明，但本公开并不限定于此。It should be noted that although the embodiment of the present disclosure first puts the legal transaction request (including the first transaction request and the second transaction request) on the chain, and then the node device calls the smart contract to execute the transaction request after the chain to obtain the transaction The execution result (including the first transaction execution result, the second transaction execution result and the target transaction execution result) is described as an example, but the present disclosure is not limited thereto.

在其他实施例中，节点设备也可以在验证交易请求具有合法性后，先执行交易请求获得对应的交易执行结果，然后打包交易请求对应的交易执行结果生成新的区块再上链。In other embodiments, the node device may also execute the transaction request to obtain the corresponding transaction execution result after verifying the legitimacy of the transaction request, and then package the transaction execution result corresponding to the transaction request to generate a new block and then upload it to the chain.

在另一些实施例中，节点设备也可以在验证交易请求具有合法性后，将具有合法性的交易请求上链，然后对应的终端例如第二终端202从区块链上拉取该交易请求对应的区块，由第二终端202执行拉取的区块中的交易请求，获得对应的交易执行结果，然后，第二终端202将交易执行结果作为交易数据上传至区块链网络，区块链网络中的节点设备将包括交易执行结果的交易数据打包进区块然后上链。例如，若区块中的交易请求涉及到转账，则第二终端202可以是银行机构。In some other embodiments, the node device may also upload the legal transaction request to the blockchain after verifying that the transaction request is legal, and then the corresponding terminal such as the second terminal 202 pulls the corresponding transaction request from the blockchain. block, the second terminal 202 executes the transaction request in the pulled block to obtain the corresponding transaction execution result, and then, the second terminal 202 uploads the transaction execution result to the blockchain network as transaction data, and the blockchain Node devices in the network pack transaction data including transaction execution results into blocks and then upload them to the chain. For example, if the transaction request in the block involves money transfer, the second terminal 202 may be a banking institution.

在示例性实施例中，调用所述智能合约获取所述第二交易请求的第二交易执行结果，还可包括：若所述第二区块上链失败，或者，所述第二区块上链成功且执行所述第二交易请求失败，则所述第二交易执行结果为执行所述第二交易请求失败。In an exemplary embodiment, invoking the smart contract to obtain the second transaction execution result of the second transaction request may further include: if the second block chaining fails, or, If the chain is successful and the execution of the second transaction request fails, then the execution result of the second transaction is that the execution of the second transaction request fails.

其中，所述方法还可包括：若所述第二交易执行结果为执行所述第二交易请求失败，则回滚所述第二交易请求中成功执行的交易操作；将所述第二交易执行结果返回至所述第一请求方的终端设备。Wherein, the method may further include: if the execution result of the second transaction is that the execution of the second transaction request fails, rolling back the successful execution of the transaction operation in the second transaction request; executing the second transaction The result is returned to the terminal device of the first requesting party.

当在区块链上执行多个交易操作时，可能出现部分交易操作成功、部分交易操作失败的情况，多个交易操作不具有一致性，会降低区块链上交易数据的准确性。When multiple transaction operations are performed on the blockchain, some transaction operations may succeed and some transaction operations may fail. Multiple transaction operations are not consistent, which will reduce the accuracy of transaction data on the blockchain.

区块链具有事务性特点，即当多个交易操作在区块链上执行，且这多个交易操作中部分交易操作执行成功，部分交易操作执行失败时，将执行成功的交易操作进行回滚，使得区块链可以回到执行第二交易请求之前的状态，保证区块链上多个交易操作具有一致性和原子性，避免区块链上出现不准确的交易数据，进而提高区块链的稳定性。The blockchain has transactional characteristics, that is, when multiple transaction operations are executed on the blockchain, and some of the transaction operations in the multiple transaction operations are successfully executed, and some of the transaction operations fail to execute, the successful transaction operations will be rolled back , so that the blockchain can return to the state before the execution of the second transaction request, ensuring the consistency and atomicity of multiple transaction operations on the blockchain, avoiding inaccurate transaction data on the blockchain, and improving the blockchain stability.

具体地，节点设备获取第二交易请求，在区块链上执行第二交易请求对应的至少一个交易操作，当至少一个交易操作中存在任一个操作失败时，对操作成功的交易操作执行回滚处理。下面以至少一个交易操作包括第一交易操作和第二交易操作为例进行举例说明。Specifically, the node device acquires the second transaction request, executes at least one transaction operation corresponding to the second transaction request on the blockchain, and when any operation fails in at least one transaction operation, rollback is performed on the successful transaction operation deal with. The following takes an example where at least one transaction operation includes a first transaction operation and a second transaction operation as an example for illustration.

第一交易操作和第二交易操作可以包括：区块链上的电子资源转移操作，区块链上的消费凭证信息(可以实现消费发票)转移操作，区块链上的鉴权证明操作，区块链上的物流防伪追溯证明操作，以及与区块链相关联的记录表的调整操作等中的至少一个。The first transaction operation and the second transaction operation may include: electronic resource transfer operation on the block chain, transfer operation of consumption certificate information (which can realize consumption invoice) on the block chain, authentication proof operation on the block chain, area At least one of the logistics anti-counterfeit traceability certification operation on the block chain, and the adjustment operation of the record table associated with the block chain.

电子资源或消费凭证信息的转移操作是指将电子资源在区块链上的账户之间进行转移；鉴权证明操作是指将权益证明文件等添加至区块链上(登记)，后续可以从区块链上查询权益；物流防伪追溯证明操作是指商品生产到销售过程都被记录至区块链上，依赖于区块链的数据不可篡改性，保证已销售出去的商品信息被永久记录，实现商品从生产到销售的整个过程都有迹可循；交易记录表的调整操作是指在交易记录表中调整区块链上所有账户的剩余资源量。The transfer operation of electronic resources or consumption certificate information refers to the transfer of electronic resources between accounts on the blockchain; the operation of authentication certification refers to the addition of rights and interests certification documents to the blockchain (registration), and subsequent transactions can be made from Query rights and interests on the block chain; logistics anti-counterfeiting traceability certification operation means that the production and sales process of goods are recorded on the block chain, relying on the data of the block chain cannot be tampered with, ensuring that the information of the sold goods is permanently recorded, The entire process from production to sales of goods can be traced; the adjustment operation of the transaction record table refers to the adjustment of the remaining resources of all accounts on the blockchain in the transaction record table.

例如，第一交易操作是电子资源转移操作，第二交易操作是权益证明文件上链操作，就是用户在区块链上支付一定的电子资源，可以在区块链上保存自己的权益证明文件。又或者，第一交易操作是资源数据转移操作，第二交易操作是商品物流上链操作，就是用户在区块链上支付一定的电子资源，可以在区块链上保存商品的物流轨迹，生产视频等。For example, the first transaction operation is an electronic resource transfer operation, and the second transaction operation is an equity certificate file on-chain operation, that is, the user pays a certain amount of electronic resources on the blockchain, and can save his own equity certificate file on the blockchain. Or, the first transaction operation is a resource data transfer operation, and the second transaction operation is a commodity logistics on-chain operation, that is, the user pays a certain amount of electronic resources on the blockchain, and the logistics track of the commodity can be saved on the blockchain, and the production video etc.

下面以第一交易操作和第二交易操作分别为转移操作和调整操作为例进行说明：The following takes the first transaction operation and the second transaction operation as a transfer operation and an adjustment operation as an example for illustration:

其中，当第一交易操作和第二交易操作中存在任一个操作失败时，对操作成功的交易操作执行回滚处理，可包括：当第一交易操作是操作失败的交易操作，且第二交易操作是操作成功的交易操作时，将第二交易操作作为目标交易操作；当第二交易操作是操作失败的交易操作，且第一交易操作是操作成功的交易操作时，将第一交易操作作为目标交易操作；对目标交易操作执行回滚处理。目标交易操作包括目标交易量和目标交易账户。目标交易账户包括转出账户和转入账户。下面均以第二交易操作为目标交易操作为例进行举例说明。Wherein, when any one of the first transaction operation and the second transaction operation fails, performing rollback processing on the successful transaction operation may include: when the first transaction operation is a failed transaction operation, and the second transaction operation When the operation is a successful transaction operation, take the second transaction operation as the target transaction operation; when the second transaction operation is a failed transaction operation, and the first transaction operation is a successful transaction operation, take the first transaction operation as Target transaction operation; perform rollback processing on the target transaction operation. The target trading operation includes a target trading volume and a target trading account. Target transaction accounts include transfer-out accounts and transfer-in accounts. In the following, the second transaction operation is taken as the target transaction operation as an example for illustration.

例如，假设目标交易操作包括转移操作(第一交易操作)和调整操作(第二交易操作)，转移操作是指在区块链上转移与目标交易量等量的资源数据，调整操作是指在与区块链关联的交易记录表中调整目标交易账户的剩余资源量，交易记录表用于记录区块链上的所有交易账户的剩余资源量。For example, assume that the target transaction operation includes a transfer operation (the first transaction operation) and an adjustment operation (the second transaction operation). The remaining resources of the target transaction account are adjusted in the transaction record table associated with the blockchain, and the transaction record table is used to record the remaining resources of all transaction accounts on the blockchain.

其中，对目标交易操作执行回滚处理，可包括：将存储在目标区块中的目标交易记录进行作废处理，目标区块属于区块链，目标区块是执行转移操作生成的区块；根据目标交易量，在交易记录表中更新目标交易账户的剩余资源量；更新后的目标交易账户的剩余资源量与执行调整操作前的目标交易账户的剩余资源量相同。Among them, performing rollback processing on the target transaction operation may include: invalidating the target transaction record stored in the target block, the target block belongs to the block chain, and the target block is a block generated by executing the transfer operation; according to For the target transaction volume, update the remaining resources of the target transaction account in the transaction record table; the remaining resources of the updated target transaction account are the same as the remaining resources of the target transaction account before the adjustment operation is performed.

例如，如图2所示，假设4个节点设备都会存储一条区块链。如图3所示，区块链中假设已经包括3个区块。For example, as shown in Figure 2, it is assumed that all four node devices will store a blockchain. As shown in Figure 3, it is assumed that 3 blocks have been included in the blockchain.

节点设备获取区块链上的第二交易请求，假设第二交易请求所请求的是从区块链上的账户1(转出账户)向账户2(转入账户)转移数量为10(目标交易量)的电子资源。The node device obtains the second transaction request on the blockchain, assuming that what the second transaction request requests is to transfer an amount of 10 (target transaction) from account 1 (transfer-out account) to account 2 (transfer-in account) on the blockchain volume) of electronic resources.

节点设备判断账户1和账户2是否是区块链上的账户，当前区块链的长度是否达到最大存储容量(即，是否还能再向区块链中写入数据)等等。若判断出账户1和账户2是区块链上的账户，且判断出当前区块链的长度未达到最大存储容量，节点设备可以从交易记录表中获取转出账户的当前剩余资源量，若转出账户的当前剩余资源量不小于目标交易量，则可以生成与第二交易请求对应的目标交易记录。The node device judges whether account 1 and account 2 are accounts on the blockchain, whether the length of the current blockchain reaches the maximum storage capacity (that is, whether data can be written into the blockchain), and so on. If it is judged that account 1 and account 2 are accounts on the blockchain, and it is judged that the length of the current blockchain has not reached the maximum storage capacity, the node device can obtain the current remaining resource amount of the transferred account from the transaction record table, if If the current remaining resource amount of the transfer-out account is not less than the target transaction amount, a target transaction record corresponding to the second transaction request may be generated.

若转出账户的当前剩余资源量小于目标交易量，或者区块链上根本就不存在转出账户或转入账户，说明当前不满足电子资源转移条件，可以确定第一交易操作执行失败，进而说明第二交易请求执行失败，可以停止第二交易请求中其他还未开始执行的交易操作。If the current remaining resource amount of the transfer-out account is less than the target transaction amount, or there is no transfer-out account or transfer-in account on the blockchain, it means that the current electronic resource transfer condition is not met, and it can be determined that the first transaction operation failed, and then Indicates that the execution of the second transaction request failed, and other transaction operations in the second transaction request that have not yet started to be executed can be stopped.

例如，从交易记录表中查询到账户1的当前剩余资源量等于40，因此账户1的当前剩余资源量大于目标交易量10，则从账户1向账户2转入数量为10的电子资源，可以生成目标交易记录：(转出地址：账户1；转入地址：账户2；资源量：10)，第一交易操作执行成功，在区块链上将转移电子资源的目标交易记录存储至区块链上。For example, if it is found from the transaction record table that the current remaining resource amount of account 1 is equal to 40, so the current remaining resource amount of account 1 is greater than the target transaction amount of 10, then transfer 10 electronic resources from account 1 to account 2, you can Generate the target transaction record: (transfer-out address: account 1; transfer-in address: account 2; resource amount: 10), the first transaction operation is successfully executed, and the target transaction record for transferring electronic resources is stored in the block chain chain.

将上述目标交易记录存储至区块体，计算目标交易记录的默克尔根，获取当前区块链的最后一个区块(即第3个区块)的哈希散列值以及当前时间戳，将默克尔根、最后一个区块的哈希散列值以及当前时间戳存储至区块头，将上述区块头以及存储了目标交易记录的区块体组合为目标区块，将新生成的目标添加到区块链中。一旦将目标交易记录添加至区块链上，就证明完成了对电子资源的转移操作，即成功执行了第一交易操作。Store the above target transaction record in the block body, calculate the Merkle root of the target transaction record, obtain the hash value of the last block (that is, the third block) of the current blockchain and the current timestamp, Store the Merkle root, the hash value of the last block and the current timestamp in the block header, combine the above block header and the block body storing the target transaction records into the target block, and store the newly generated target added to the blockchain. Once the target transaction record is added to the block chain, it proves that the transfer operation of the electronic resource is completed, that is, the first transaction operation is successfully executed.

第一交易操作执行成功后，区块链就包括了4个区块，最后一个区块是新生成的目标区块，目标区块中存储了第一交易操作对应的目标交易记录。After the first transaction operation is successfully executed, the blockchain includes 4 blocks, the last block is a newly generated target block, and the target transaction record corresponding to the first transaction operation is stored in the target block.

若判断出账户1或者账户2在区块链上根本不存在，或者判断出当前区块链的长度已经达到最大存储容量，或者判断出账户1的当前剩余资源量小于10，则表明第一交易操作执行失败。If it is judged that account 1 or account 2 does not exist on the blockchain at all, or it is judged that the length of the current blockchain has reached the maximum storage capacity, or it is judged that the current remaining resource of account 1 is less than 10, it indicates that the first transaction Operation execution failed.

第二交易操作可以与第一交易操作可以并行执行，也可以串行执行，即先执行第一交易操作之后再执行第二交易操作，或者先执行第二交易操作再执行第一交易操作，可以根据第一交易操作和第二交易操作之间是否存在依赖关系来确定。The second transaction operation can be executed in parallel with the first transaction operation, or it can be executed in series, that is, the first transaction operation is executed first and then the second transaction operation is executed, or the second transaction operation is executed first and then the first transaction operation is executed. It is determined according to whether there is a dependency relationship between the first transaction operation and the second transaction operation.

若交易记录表中存在转出账户和转入账户，且转出账户的当前剩余资源量不小于目标交易量，根据第二交易请求调整转出账户的剩余资源量和转入账户的剩余资源量。If there are transfer-out accounts and transfer-in accounts in the transaction record table, and the current remaining resources of the transfer-out account are not less than the target transaction amount, adjust the remaining resources of the transfer-out account and the remaining resources of the transfer-in account according to the second transaction request .

例如，还是假设第二交易请求为：请求将资源量为10的电子资源从账户1转移至账户2，从交易记录表中查询到账户1的当前剩余资源量为40，账户2的当前剩余资源量为20，调整操作即第二交易操作即是在交易记录表中将账户1的剩余资源量调整为40-10＝30，在交易记录表中将账户2的剩余资源量调整为20+10＝30。For example, assume that the second transaction request is: a request to transfer electronic resources with a resource amount of 10 from account 1 to account 2, and it is found from the transaction record table that the current remaining resource amount of account 1 is 40, and the current remaining resource amount of account 2 is The amount is 20, the adjustment operation, that is, the second transaction operation, is to adjust the remaining resource amount of account 1 to 40-10=30 in the transaction record table, and adjust the remaining resource amount of account 2 to 20+10 in the transaction record table =30.

此时，若第一交易操作执行成功，但第二交易操作执行失败，节点设备需要对执行成功的交易操作(即第一交易操作)进行回滚。对第一交易操作进行回滚的具体过程为：由于成功执行了第一交易操作后，对应的目标交易记录1已经被存储在区块链上，因此需要将区块链上的目标交易记录作废，若目标区块中只存储了目标交易记录而没有存储其他交易记录，还可以进一步地将新生成的目标区块设置为无效区块。At this time, if the execution of the first transaction operation is successful, but the execution of the second transaction operation fails, the node device needs to roll back the successful execution of the transaction operation (that is, the first transaction operation). The specific process of rolling back the first transaction operation is as follows: After the first transaction operation is successfully executed, the corresponding target transaction record 1 has been stored on the blockchain, so the target transaction record on the blockchain needs to be invalidated , if only the target transaction record is stored in the target block and no other transaction records are stored, the newly generated target block can be further set as an invalid block.

或者，节点设备根据第二交易请求再生成新的交易请求(称为回滚交易请求)，回滚交易请求中的交易账户以及交易量和第二交易请求中的目标交易账户和目标交易量完全相同，不同之处在于第二交易请求中的转入账户是回滚交易请求中的转出账户，第二交易请求中的转出账户是回滚交易请求中的转入账户。Or, the node device regenerates a new transaction request (called a rollback transaction request) according to the second transaction request, and the transaction account and transaction volume in the rollback transaction request are completely equal to the target transaction account and target transaction volume in the second transaction request. The same, except that the transfer-in account in the second transaction request is the transfer-out account in the rollback transaction request, and the transfer-out account in the second transaction request is the transfer-in account in the rollback transaction request.

例如，第二交易请求为：请求将资源量为10的电子资源从账户1转移至账户2，回滚交易请求为：请求将资源量为10的电子资源从账户2转移至账户1。For example, the second transaction request is: a request to transfer electronic resources with a resource amount of 10 from account 1 to account 2, and the rollback transaction request is: a request to transfer electronic resources with a resource amount of 10 from account 2 to account 1.

节点设备可以执行回滚交易请求对应的交易操作，执行完回滚交易请求对应的交易操作后，所达到的效果等同于对第一交易操作中的转移操作进行了回滚处理。The node device can execute the transaction operation corresponding to the rollback transaction request. After executing the transaction operation corresponding to the rollback transaction request, the effect achieved is equivalent to performing rollback processing on the transfer operation in the first transaction operation.

分析知道，若不对第一交易操作进行回滚，相当于账户2中凭空出现了数量为10的电子资源，或者说在区块链上凭空出现了数量为10的电子资源，这种由于多个交易操作不具有一致性所凭空出现的电子资源，就是区块链上的不正确的交易数据，可见不正确的交易数据会破坏区块链的稳定性。The analysis shows that if the first transaction operation is not rolled back, it is equivalent to the number of 10 electronic resources appearing out of thin air in Account 2, or the number of 10 electronic resources appearing out of thin air on the blockchain. The electronic resources that appear out of thin air due to the inconsistency of transaction operations are incorrect transaction data on the blockchain. It can be seen that incorrect transaction data will destroy the stability of the blockchain.

后续基于区块链统计账户1的剩余资源量和账户2的剩余资源量时，由于第一交易操作是无效区块，且第一交易操作的目标交易记录是无效交易记录，因此遍历区块链中的所有区块时，可以不必遍历目标区块；或者遍历区块链中的所有区块时，可以不将目标区块中的目标交易记录纳入统计范围内。Subsequent statistics on the remaining resources of account 1 and account 2 based on the blockchain, since the first transaction operation is an invalid block, and the target transaction record of the first transaction operation is an invalid transaction record, the block chain is traversed When traversing all blocks in the block chain, it is not necessary to traverse the target block; or when traversing all blocks in the blockchain, the target transaction records in the target block may not be included in the statistical range.

若第二交易操作执行成功，但第一交易操作执行失败，节点设备需要对执行成功的交易操作(即第二交易操作)进行回滚。对第二交易操作进行回滚的具体过程为：If the execution of the second transaction operation is successful, but the execution of the first transaction operation fails, the node device needs to roll back the successful execution of the transaction operation (that is, the second transaction operation). The specific process of rolling back the second transaction operation is:

节点设备获取第二交易请求中的目标交易量，根据该目标交易量在交易记录表中更新目标交易账户的剩余资源量，使得更新后的目标交易账户的剩余资源量与执行调整操作前的目标交易账户的剩余资源量相同。The node device acquires the target transaction amount in the second transaction request, and updates the remaining resource amount of the target transaction account in the transaction record table according to the target transaction amount, so that the updated remaining resource amount of the target transaction account is the same as the target amount before the adjustment operation is performed. The trading account has the same amount of remaining resources.

例如，第二交易请求为：请求将资源量为10的电子资源从账户1转移至账户2，执行调整操作前，账户1的剩余资源量等于20，账户2的剩余资源量等于30，成功执行调整操作后，账户1的剩余资源量等于20-10＝10，账户2的剩余资源量等于30+10＝40，对该调整操作进行回滚处理即是，再将账户1的剩余资源量调整回20:30-10＝20，将账户2的剩余资源量调整回30:40-10＝30。For example, the second transaction request is: request to transfer electronic resources with a resource amount of 10 from account 1 to account 2. Before the adjustment operation is performed, the remaining resource amount of account 1 is equal to 20, and the remaining resource amount of account 2 is equal to 30, which is successfully executed After the adjustment operation, the remaining resource amount of account 1 is equal to 20-10=10, and the remaining resource amount of account 2 is equal to 30+10=40. The adjustment operation is rolled back, and then the remaining resource amount of account 1 is adjusted Back to 20:30-10=20, adjust the remaining resources of account 2 back to 30:40-10=30.

上述可知，虽然第二交易请求执行失败了，对区块链以及区块链上的账户1和账户2来说，相当于回到了第二交易请求未执行之前的状态，即未从账户1转出电子资源，也未将电子资源转入账户2，多个交易操作具有一致性和原子性，能够保证区块链上的交易数据的准确性和完整性。It can be seen from the above that although the execution of the second transaction request failed, for the blockchain and account 1 and account 2 on the blockchain, it is equivalent to returning to the state before the second transaction request was not executed, that is, the transfer from account 1 to The electronic resources have not been transferred to the account 2, and multiple transaction operations are consistent and atomic, which can ensure the accuracy and integrity of the transaction data on the blockchain.

需要说明的是，执行第二交易请求的过程中可以包括多个交易操作(例如，转移操作和调整操作)，只有这多个交易操作都执行成功，才确定该第二交易请求执行成功，反之一旦存在至少一个交易操作执行失败，就确定该第二交易请求执行失败。It should be noted that the process of executing the second transaction request may include multiple transaction operations (for example, a transfer operation and an adjustment operation), and only when all these multiple transaction operations are executed successfully can the execution of the second transaction request be determined to be successful, and vice versa Once at least one transaction operation fails to execute, it is determined that the execution of the second transaction request fails.

当第一交易操作和第二交易操作中存在任一个操作失败时，对操作成功的交易操作执行回滚处理，执行回滚处理可以保证在区块链上的多个操作具有一致性，使得区块链可以回到执行第一交易操作和第二交易操作之前的状态，避免区块链上出现不准确的交易数据，提高区块链的稳定性。When any one of the first transaction operation and the second transaction operation fails, rollback processing is performed on the successful transaction operation. Performing rollback processing can ensure the consistency of multiple operations on the blockchain, making the block The block chain can return to the state before the execution of the first transaction operation and the second transaction operation, avoiding inaccurate transaction data on the block chain, and improving the stability of the block chain.

在步骤S650中，若所述第二交易执行结果为成功执行所述第二交易请求，则将所述第二交易执行结果作为所述目标交易执行结果，并获取所述第二交易请求的目标交易哈希值。In step S650, if the second transaction execution result is the successful execution of the second transaction request, use the second transaction execution result as the target transaction execution result, and obtain the target of the second transaction request Transaction hash.

本公开实施例中，目标交易执行结果中可以包括表明第二交易请求执行成功的指示信息，例如“1”表示第二交易请求执行成功，“0”表示第二交易请求执行失败，但本公开并不限定于此。在另一些实施例中，目标交易执行结果中还可以包括成功执行第二交易请求之后的具体的返回值。In the embodiment of the present disclosure, the target transaction execution result may include indication information indicating that the second transaction request is executed successfully, for example, "1" indicates that the second transaction request is executed successfully, and "0" indicates that the second transaction request fails to be executed, but the present disclosure It is not limited to this. In some other embodiments, the target transaction execution result may also include a specific return value after the second transaction request is successfully executed.

本公开实施例中，对节点设备如何获得第二交易请求的目标交易哈希值不做限定。In the embodiment of the present disclosure, there is no limitation on how the node device obtains the target transaction hash value of the second transaction request.

在一些实施例中，节点设备可以采用哈希函数对第二交易请求进行运算，获得目标交易哈希值。In some embodiments, the node device may use a hash function to perform operations on the second transaction request to obtain a target transaction hash value.

在另一些实施例中，若第一终端201在生成第二交易请求时，对第二交易请求进行哈希运算，得到第二交易请求的第二交易哈希值，并采用私钥对第二交易请求的哈希值进行加密，得到携带第一终端201的签名的第二交易请求，然后将第二交易请求和携带第一终端的签名的第二交易请求一起发送至区块链网络的节点设备，则节点设备在接收到第二交易请求和携带第一终端的签名的第二交易请求后，可以获取第一终端201的公钥，节点设备采用公钥对携带第一终端的签名的第二交易请求进行解密，获得目标交易哈希值。In some other embodiments, if the first terminal 201 performs a hash operation on the second transaction request when generating the second transaction request, obtains the second transaction hash value of the second transaction request, and uses the private key to pair the second The hash value of the transaction request is encrypted to obtain the second transaction request carrying the signature of the first terminal 201, and then the second transaction request and the second transaction request carrying the signature of the first terminal are sent to the nodes of the blockchain network device, the node device can obtain the public key of the first terminal 201 after receiving the second transaction request and the second transaction request carrying the signature of the first terminal, and the node device uses the public key to pair the second transaction request carrying the signature of the first terminal The second transaction request is decrypted to obtain the target transaction hash value.

在步骤S660中，调用所述智能合约将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值关联存储至所述交易执行表中。In step S660, the smart contract is invoked to generate the first business party ID, the first requester information, the first parameter hash value, the target transaction execution result, and the target transaction hash value Value associations are stored in the transaction execution table.

本公开实施例中，在成功执行第二交易请求之后，可以将第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值及其对应的目标交易执行结果和目标交易哈希值存储至交易执行表中，以用于对后续接收到的与第二交易请求针对的是相同业务的交易请求进行去重过滤，防止重复执行，保证幂等性。In the embodiment of the present disclosure, after the second transaction request is successfully executed, the first business party identification, first requester information, first parameter hash value and the corresponding target transaction execution result carried in the second transaction request can be and the target transaction hash value are stored in the transaction execution table, which is used to de-duplicate and filter subsequent received transaction requests for the same business as the second transaction request, to prevent repeated execution, and to ensure idempotence.

在一些实施例中，将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值关联存储至所述交易执行表中，可以是直接将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值存储至交易执行表中，第一业务方标识作为目标业务方标识，第一请求方信息作为目标请求方信息，第一传参哈希值作为目标传参哈希值。In some embodiments, the first business party identifier, the first requester information, the first parameter hash value, the target transaction execution result, and the target transaction hash value are associated and stored in In the transaction execution table, the first business party identifier, the first requester information, the first parameter hash value, the target transaction execution result, and the target transaction hash value may be directly The value is stored in the transaction execution table, the first business party ID is used as the target business party ID, the first requester information is used as the target requester information, and the first passed parameter hash value is used as the target passed parameter hash value.

在另一些实施例中，节点设备可以根据第二交易请求中的第一业务方标识生成第二交易请求的第一平台方标识。其中，将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值关联存储至所述交易执行表中，可以将第二交易请求的所述第一业务方标识、第一平台方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值存储至交易执行表中，第一业务方标识作为目标业务方标识，第一平台方标识作为目标平台方标识，第一请求方信息作为目标请求方信息，第一传参哈希值作为目标传参哈希值。In some other embodiments, the node device may generate the first platform party identifier of the second transaction request according to the first business party identifier in the second transaction request. Wherein, the first business party identifier, the first requester information, the first parameter hash value, the target transaction execution result and the target transaction hash value are associated and stored in the transaction execution In the table, the first business party ID, the first platform party ID, the first requester information, the first parameter hash value, the target transaction execution result and the The target transaction hash value is stored in the transaction execution table, the first business party ID is used as the target business party ID, the first platform party ID is used as the target platform party ID, the first requester information is used as the target requester information, and the first parameter The hash value is passed as the hash value of the target parameter.

在又一些实施例中，节点设备可以根据第二交易请求携带的第一业务方标识生成第一平台方标识，再根据第一业务方标识和第一平台方标识生成第一数据实体标识。将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值关联存储至所述交易执行表中，可以将第二交易请求的第一数据实体标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值存储至交易执行表中，第一数据实体标识作为目标数据实体标识，第一请求方信息作为目标请求方信息，第一传参哈希值作为目标传参哈希值。In some other embodiments, the node device may generate the first platform party ID according to the first business party ID carried in the second transaction request, and then generate the first data entity ID according to the first business party ID and the first platform party ID. Store the first business party identifier, the first requester information, the first parameter hash value, the target transaction execution result, and the target transaction hash value in the transaction execution table , the first data entity identifier of the second transaction request, the first requester information, the first parameter hash value, the target transaction execution result, and the target transaction hash value can be stored in the transaction execution In the table, the first data entity identifier is used as the target data entity identifier, the first requester information is used as the target requester information, and the first passed parameter hash value is used as the target passed parameter hash value.

在再一些实施例中，节点设备可以根据第二交易请求携带的第一业务方标识生成第一平台方标识，再根据第一业务方标识和第一平台方标识生成第一数据实体标识，再根据第一数据实体标识、第一请求方信息和第一传参哈希值生成第一交易执行表唯一键，将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述目标交易执行结果和所述目标交易哈希值关联存储至所述交易执行表中，可以将第二交易请求的第一交易执行表唯一键、所述目标交易执行结果和所述目标交易哈希值存储至交易执行表中，第一交易执行表唯一键作为目标交易执行表唯一键。In some other embodiments, the node device may generate the first platform party ID according to the first business party ID carried in the second transaction request, and then generate the first data entity ID according to the first business party ID and the first platform party ID, and then Generate the unique key of the first transaction execution table according to the first data entity identifier, the first requestor information and the first parameter hash value, and combine the first business party identifier, the first requestor information, the first The reference hash value, the target transaction execution result and the target transaction hash value are associated and stored in the transaction execution table, and the unique key of the first transaction execution table of the second transaction request, the target transaction execution The result and the hash value of the target transaction are stored in the transaction execution table, and the unique key of the first transaction execution table is used as the unique key of the target transaction execution table.

在步骤S670中，将所述目标交易执行结果和所述目标交易哈希值返回至所述第一请求方的终端设备，所述目标交易哈希值与所述第二交易请求的第二交易哈希值相同。In step S670, return the target transaction execution result and the target transaction hash value to the terminal device of the first requesting party, the target transaction hash value and the second transaction requested by the second transaction The hashes are the same.

具体的，在第二交易请求未被上传至节点设备101时，第一终端201可对第二交易请求进行哈希运算，得到第二交易请求的第二交易哈希值。当节点设备将成功执行第二交易请求获得的目标交易哈希值返回至第一终端时，第一终端可以将接收到的目标交易哈希值与第二交易哈希值进行比较，若两者一致，则可以判定本次接收到的目标交易执行结果是成功执行第二交易请求返回的，历史上没有执行过与第二交易请求相同的业务。Specifically, when the second transaction request is not uploaded to thenode device 101, the first terminal 201 may perform a hash operation on the second transaction request to obtain a second transaction hash value of the second transaction request. When the node device returns the target transaction hash value obtained by successfully executing the second transaction request to the first terminal, the first terminal can compare the received target transaction hash value with the second transaction hash value, and if both If they are consistent, it can be determined that the target transaction execution result received this time is returned by the successful execution of the second transaction request, and the same business as the second transaction request has not been executed in history.

图7示意性示出了根据本公开的一个实施例的基于区块链的数据处理方法的流程示意图。如图7所示，可以包括如下步骤。Fig. 7 schematically shows a schematic flowchart of a blockchain-based data processing method according to an embodiment of the present disclosure. As shown in Fig. 7, the following steps may be included.

在步骤S710中，交易提交。In step S710, the transaction is submitted.

本公开实施例中，交易提交可以是指任意终端设备发送给区块链网络中的节点设备的交易请求，可以包括上述的第一终端201发送给节点设备101的第一交易请求和第二交易请求。In the embodiment of the present disclosure, the transaction submission may refer to the transaction request sent by any terminal device to the node device in the blockchain network, and may include the above-mentioned first transaction request and the second transaction request sent by the first terminal 201 to thenode device 101 ask.

任意终端设备发送给区块链网络中的节点设备的交易请求中均指定了业务方标识，例如上述第一交易请求中指定了第一业务方标识，第二交易请求中也指定了第一业务方标识，以用于区分每次交易请求所针对的操作对象是谁。The business party ID is specified in the transaction request sent by any terminal device to the node device in the blockchain network. For example, the first business party ID is specified in the above-mentioned first transaction request, and the first business party ID is also specified in the second transaction request. The party ID is used to distinguish who is the target of each transaction request.

在步骤S720中，区块链核心(Core)710执行重复交易过滤。In step S720, the blockchain core (Core) 710 performs duplicate transaction filtering.

本公开实施例中，区块链网络接收到任意终端设备发送的交易请求后，可以利用智能合约维护的交易执行表对接收到的交易请求进行重复交易过滤，这里的重复交易过滤是指判断当前接收到的交易请求是否在此之前被成功执行过并记录在交易执行表中，防止针对相同业务的交易请求被重复执行。In the embodiment of the present disclosure, after the blockchain network receives a transaction request sent by any terminal device, it can use the transaction execution table maintained by the smart contract to filter the received transaction request for repeated transactions. The repeated transaction filtering here refers to judging the current Whether the received transaction request has been successfully executed before and recorded in the transaction execution table to prevent repeated execution of transaction requests for the same business.

具体地，上述步骤S720可以进一步包括以下由业务合约720执行的以下步骤。Specifically, the above step S720 may further include the following steps executed by the service contract 720 .

本公开实施例中，业务合约720即上述用于维护交易执行表的智能合约。In the embodiment of the present disclosure, the business contract 720 is the aforementioned smart contract for maintaining the transaction execution table.

在步骤S721中，查询交易执行表。In step S721, query the transaction execution table.

节点设备可以调用业务合约720查询交易执行表，以判断当前接收到的交易请求所针对的业务是否在历史上已经被成功执行过。The node device can call the service contract 720 to query the transaction execution table to determine whether the service targeted by the currently received transaction request has been successfully executed in history.

在步骤S722中，返回历史执行成功交易哈希值和业务结果。In step S722, return history execution successful transaction hash value and business result.

若通过查询交易执行表，获知当前接收到的交易请求已经在历史上被成功执行过，则节点设备可以直接向发送该交易请求的终端设备返回历史执行成功交易哈希值和业务结果。If it is known that the currently received transaction request has been successfully executed in history by querying the transaction execution table, the node device can directly return the historical execution successful transaction hash value and business result to the terminal device that sent the transaction request.

例如，当节点设备接收到第一交易请求时，通过查询发现交易执行表中存在与第一交易请求携带的第一业务方标识、第一请求方信息和第一传入参数(或者第一传参哈希值)匹配的目标业务方标识、目标请求方信息和目标传入参数，可以将交易执行表中与目标业务方标识、目标请求方信息和目标传入参数匹配的目标交易执行结果(业务结果)和目标交易哈希值(历史执行成功交易哈希值)返回给第一终端。For example, when the node device receives the first transaction request, it is found by querying that the transaction execution table contains the first business party identifier, the first requester information and the first incoming parameter (or the first incoming parameter) carried in the first transaction request. reference hash value) matched target business party ID, target requester information and target incoming parameters, the target transaction execution result ( business result) and the target transaction hash value (historical execution successful transaction hash value) are returned to the first terminal.

在步骤S723中，执行业务。In step S723, execute the service.

若通过查询交易执行表，获知当前接收到的交易请求没有在历史上被成功执行过，则节点设备可以执行当前接收到的交易请求所对应的业务。If it is learned that the currently received transaction request has not been successfully executed in history by querying the transaction execution table, the node device can execute the service corresponding to the currently received transaction request.

在步骤S724中，若执行成功，则写入交易执行表。In step S724, if the execution is successful, write the transaction execution table.

例如，当节点设备接收到第二交易请求时，通过查询发现交易执行表中步存在与第二交易请求携带的第一业务方标识、第一请求方信息和第一传入参数(或者第一传参哈希值)匹配的目标业务方标识、目标请求方信息和目标传入参数，则节点设备执行该第二交易请求，获得第二交易请求的目标交易执行结果和目标交易哈希值，并将第二交易请求携带的第一业务方标识、第一请求方信息和第一传参哈希值分别作为目标业务方标识、目标请求方信息和目标传参哈希值，将目标业务方标识、目标请求方信息、目标传参哈希值、目标交易执行结果和目标交易哈希值关联存储至交易执行表中。For example, when the node device receives the second transaction request, it is found by querying the transaction execution table that the first business party identifier, the first requester information and the first incoming parameter (or the first Pass parameter hash value) matching target business party identification, target requester information and target incoming parameters, then the node device executes the second transaction request, and obtains the target transaction execution result and target transaction hash value of the second transaction request, The first business party ID, the first requester information and the first parameter hash value carried in the second transaction request are respectively used as the target business party ID, target requester information and target parameter hash value, and the target business party The identification, target requester information, target parameter hash value, target transaction execution result and target transaction hash value are associated and stored in the transaction execution table.

在步骤S725中，若执行失败或者写入交易执行表失败，则进行失败回滚。In step S725, if the execution fails or the writing into the transaction execution table fails, a failure rollback is performed.

例如，若节点设备没有成功执行第二交易请求，或者将执行成功的第二交易请求的目标业务方标识、目标请求方信息、目标传参哈希值、目标交易执行结果和目标交易哈希值关联存储至交易执行表失败，则进行失败回滚，具体的回滚过程可以参照上述实施例。For example, if the node device does not successfully execute the second transaction request, or will execute the successful second transaction request, the target business party ID, target requester information, target parameter hash value, target transaction execution result and target transaction hash value If the associated storage to the transaction execution table fails, the failure rollback will be performed, and the specific rollback process can refer to the above-mentioned embodiment.

在步骤S726中，返回步骤。具体地为，在步骤S727中，返回当前执行成功交易哈希值和业务结果。In step S726, return to step. Specifically, in step S727, the currently executed successful transaction hash value and business result are returned.

例如，若执行成功，且成功地将第二交易请求的目标业务方标识、目标请求方信息、目标传参哈希值、目标交易执行结果和目标交易哈希值关联存储至交易执行表，则向第一终端返回目标交易执行结果(业务结果)和目标交易哈希值(当前执行成功交易哈希值)。For example, if the execution is successful, and the target business party ID, target requester information, target parameter hash value, target transaction execution result and target transaction hash value of the second transaction request are successfully associated and stored in the transaction execution table, then The target transaction execution result (business result) and the target transaction hash value (currently successfully executed transaction hash value) are returned to the first terminal.

图8示意性示出了根据本公开的一个实施例的基于区块链的数据处理方法的流程示意图。图8实施例提供的方法可以应用于与区块链网络通信的终端设备，区块链网络中部署智能合约，智能合约用于维护交易执行表。Fig. 8 schematically shows a schematic flowchart of a blockchain-based data processing method according to an embodiment of the present disclosure.

在步骤S840中，接收所述节点设备返回的目标交易执行结果和目标交易哈希值，其中所述交易执行表中的所述目标交易执行结果和所述目标交易哈希值与目标业务方标识与所述第一业务方标识、所述第一请求方信息和所述第一传参哈希值匹配。In step S840, the target transaction execution result and the target transaction hash value returned by the node device are received, wherein the target transaction execution result and the target transaction hash value in the transaction execution table are related to the target business party identification Match the first service party identifier, the first requester information, and the first passed parameter hash value.

在步骤S850中，确定所述目标交易哈希值与所述第一交易哈希值不同。In step S850, it is determined that the target transaction hash value is different from the first transaction hash value.

图9示意性示出了根据本公开的又一个实施例的基于区块链的数据处理方法的流程图。图9实施例提供的方法与上述图8实施例提供的方法之间的区别在于，在上述步骤S810之前，即在通过第一请求方的终端设备生成第一交易请求之前，所述方法还可以进一步包括以下步骤。Fig. 9 schematically shows a flowchart of a blockchain-based data processing method according to yet another embodiment of the present disclosure. The difference between the method provided by the embodiment of FIG. 9 and the method provided by the embodiment of FIG. 8 above is that before the above step S810, that is, before the first transaction request is generated by the terminal device of the first requesting party, the method can also The following steps are further included.

在步骤S910中，通过所述第一请求方的终端设备生成第二交易请求，所述第二交易请求携带所述第一业务方标识、所述第一请求方信息和用于执行所述第二交易请求的第一传入参数。In step S910, a second transaction request is generated by the terminal device of the first requester, and the second transaction request carries the identifier of the first business party, the information of the first requester, and the 2. The first incoming parameter of the transaction request.

在步骤S920中，通过所述第一请求方的终端设备生成所述第二交易请求的第二交易哈希值。In step S920, a second transaction hash value of the second transaction request is generated by the terminal device of the first requester.

在步骤S930中，通过所述第一请求方的终端设备向所述区块链网络中的节点设备发送所述第二交易请求，以便所述节点设备调用所述智能合约生成所述第一传入参数的第一传参哈希值，若所述交易执行表与所述第一业务方标识、所述第一请求方信息和所述第一传参哈希值不匹配，则成功执行所述第二交易请求，获得第二交易执行结果和第二交易哈希值，将所述第一业务方标识、所述第一请求方信息、所述第一传参哈希值、所述第二交易执行结果和所述第二交易哈希值关联存储至所述交易执行表中，其中所述第二交易执行结果作为所述目标交易执行结果，所述第二交易哈希值作为所述目标交易哈希值。In step S930, the terminal device of the first requester sends the second transaction request to the node device in the blockchain network, so that the node device invokes the smart contract to generate the first transaction request The first passed parameter hash value of the input parameter, if the transaction execution table does not match the first business party identifier, the first requester information and the first passed parameter hash value, then the transaction will be executed successfully The second transaction request is obtained, the second transaction execution result and the second transaction hash value are obtained, and the first business party ID, the first requester information, the first parameter hash value, and the second transaction hash value are obtained.

区块链具有数据永久保存，难以篡改，可追溯的特性。同时区块链以交易为单位，通过交易池对上链请求进行管理，理论上任意提交的交易被执行时间是不可预测的，交易也不能被重复提交执行。同时链上操作均是事务性的，要不然一笔交易的执行全部成功，或者全部失败被回滚，不会出现部分操作失败的情景。Blockchain has the characteristics of permanent data storage, difficult to tamper, and traceability. At the same time, the blockchain takes transactions as units, and manages the on-chain requests through the transaction pool. Theoretically, the execution time of any submitted transaction is unpredictable, and the transaction cannot be repeatedly submitted for execution. At the same time, the operations on the chain are all transactional. Otherwise, the execution of a transaction is all successful, or all failures are rolled back, and there will be no scenario where some operations fail.

本公开实施方式提供的基于区块链的数据处理方法，公开了一种基于区块链智能合约的业务请求幂等性问题的解决方案，通过交易执行表保证存在相同业务的多笔交易并发执行的情况下，也只有一笔业务能够执行成功，能够识别不同区块中包括的交易请求对应相同业务，并确保该相同业务的不同交易请求不会被重复性执行。用户可以根据交易请求中携带的业务方标识进行多次上链重试，而无需关心重复上链提交的问题，确保幂等性。通过幂等性保证，业务方在对接区块链网络时，可以避免因为区块链异步上链特性导致的返回超时，或者回包丢失等错误，可通过指定业务方标识进行多次请求重试，减少业务方的开发接入成本。The blockchain-based data processing method provided by the embodiments of the present disclosure discloses a solution to the idempotence problem of business requests based on blockchain smart contracts, and ensures that multiple transactions of the same business are executed concurrently through the transaction execution table In the case where only one business can be executed successfully, it can identify that the transaction requests included in different blocks correspond to the same business, and ensure that different transaction requests of the same business will not be executed repeatedly. Users can retry multiple times on the chain according to the business party ID carried in the transaction request, without worrying about the problem of repeated on-chain submissions to ensure idempotency. Through the guarantee of idempotence, when the business party connects to the blockchain network, it can avoid errors such as return timeout or lost return packets caused by the asynchronous uplink feature of the blockchain, and multiple request retries can be made by specifying the business party ID , to reduce the development access cost of the business side.
