为了便于理解本申请，现对本申请涉及到的相关要素进行描述。In order to facilitate the understanding of the present application, the relevant elements involved in the present application are now described.
区块链技术blockchain technology
区块链技术，也被称为分布式账本技术，是一种由若干台计算设备共同参与“记账”(即记录交易数据)，共同维护一份完整的分布式数据库的新兴技术。由于区块链技术具有去中心化(即没有中心节点)、公开透明、每台计算设备可以参与数据库记录、并且各计算设备之间可以快速的进行数据同步的特性，使得区块链技术已在众多的领域中广泛的进行应用。Blockchain technology, also known as distributed ledger technology, is an emerging technology in which several computing devices jointly participate in "bookkeeping" (that is, record transaction data) and jointly maintain a complete distributed database. Since blockchain technology has the characteristics of decentralization (that is, no central node), openness and transparency, each computing device can participate in database records, and fast data synchronization between computing devices, blockchain technology has been used in Widely applied in many fields.
区块链网络可包括多个区块链节点。区块链节点为具有通信功能以及存储功能的设备，如存储有区块链的设备。为了便于描述，本申请采用节点表示区块链节点。也就是说，本申请涉及到的节点均可用于表示区块链节点。A blockchain network may include multiple blockchain nodes. Blockchain nodes are devices with communication functions and storage functions, such as devices that store blockchains. For ease of description, this application uses nodes to represent blockchain nodes. That is to say, all the nodes involved in this application can be used to represent blockchain nodes.
每一个节点既可接收信息，也可生成信息。不同的节点之间通过维护一个共同的区块链来保持通信。具体的，在区块链网络中，任一节点可以根据客户端发送的与交易相关的数据生成新的区块，并以广播的形式通知其他节点，其他节点可以对这个区块进行验证。当区块链网络中的所有节点达成共识后，新的区块就可以被添加到区块链中。Each node can both receive information and generate information. Different nodes maintain communication by maintaining a common blockchain. Specifically, in the blockchain network, any node can generate a new block based on the transaction-related data sent by the client, and notify other nodes in the form of broadcast, and other nodes can verify the block. When all nodes in the blockchain network reach a consensus, new blocks can be added to the blockchain.
节点分为共识节点和普通节点。共识节点具有出块和投票权限，交易由共识节点排序并打包成块，共识完成后即被确认为合法区块。普通节点没有出块和投票权限，其他方面和共识节点相同。可以同步区块链上所有的原始数据，接受交易数据并向其他节点广播。普通节点的管理，是指普通节点的添加与删除，通过修改配置文件中连接的节点列表来实现。新的普通节点接入网络，必须连接已经在区块链网络内的节点。Nodes are divided into consensus nodes and ordinary nodes. Consensus nodes have the authority to produce blocks and vote. Transactions are sorted and packaged into blocks by consensus nodes. After the consensus is completed, they are confirmed as legal blocks. Ordinary nodes do not have block production and voting rights, and are the same as consensus nodes in other respects. All original data on the blockchain can be synchronized, transaction data can be accepted and broadcast to other nodes. The management of ordinary nodes refers to the addition and deletion of ordinary nodes, which is realized by modifying the list of connected nodes in the configuration file. New ordinary nodes accessing the network must connect to nodes already in the blockchain network.
本申请中的节点可以理解为处理单元。在一种实现方式中，节点可以为物理设备，例如服务器或终端设备。在另一种实现方式中，节点可以为虚拟计算机；虚拟计算机为所有类型的虚拟化设备中软件虚拟出来的运行环境的统称，该概念包括虚拟机、容器。在其他实现方式中，节点可以为进程(process)或者线程(thread)；线程是操作系统能够进行运算调度的最小单位，线程被包含在进程之中，是进程中的实际运作单位；进程是计算机中的程序关于某数据集合上的一次运行活动，是系统进行资源分配和调度的基本单位。A node in this application can be understood as a processing unit. In an implementation manner, a node may be a physical device, such as a server or a terminal device. In another implementation manner, the node may be a virtual computer; a virtual computer is a general term for an operating environment virtualized by software in all types of virtualization devices, and the concept includes virtual machines and containers. In other implementations, a node can be a process or a thread; a thread is the smallest unit that the operating system can perform operation scheduling, and a thread is included in a process, which is the actual operating unit in the process; a process is a computer The program in is about a running activity on a data set, and is the basic unit for the system to allocate and schedule resources.
区块链的划分Blockchain division
目前，区块链按照部署方式可以分为：公有链、私有链、联盟链。At present, blockchain can be divided into: public chain, private chain and alliance chain according to the deployment method.
公有链是指全世界任何设备都可读取的区块链，或者是任何设备都能参与交易的共识验证过程的区块链。A public chain refers to a blockchain that can be read by any device in the world, or a blockchain that any device can participate in the consensus verification process of transactions.
私有链是指访问权限控制较为严格的区块链。A private chain refers to a blockchain with strict access control.
联盟链，也称共同体区块链(consortium blockchains)，是指其共识过程受到预选节点控制的区块链。在联盟链中，只针对存储有该联盟链的节点开放全部或部分功能，联盟链中的各个节点可以基于需要定制读写权限、查询权限等。Consortium chains, also known as consortium blockchains, refer to blockchains whose consensus process is controlled by pre-selected nodes. In the consortium chain, all or part of the functions are only open to the nodes that store the consortium chain, and each node in the consortium chain can customize read and write permissions, query permissions, etc. based on needs.
智能合约(smart contract)smart contract
智能合约本质是能跑在区块链上的代码，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。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。一个智能合约是一套以数字形式定义的承诺(promises)，包括合约参与方可以在上面执行这些承诺的协议。数字形式意味着合约不得不写入计算机可读的代码中。这是必须的，因为只要参与方达成协定，智能合约建立的权利和义务，是由一台计算机或者计算机网络执行的。智能合约建立的具体过程包括：达成协议、合约执行、生成计算机可读的代码。The essence of a smart contract is code that can run on the blockchain. It is a computer protocol designed to spread, verify or execute contracts in an informational manner. Smart contracts allow for trusted transactions without third parties, which are traceable and irreversible. A smart contract is a set of promises defined in digital form, including agreements on which contract participants can implement these promises. The digital form means that contracts have to be written in computer-readable code. This is necessary because as long as the parties reach an agreement, the rights and obligations established by the smart contract are executed by a computer or computer network. The specific process of establishing a smart contract includes: reaching an agreement, contract execution, and generating computer-readable code.
区块(block)block
在区块链技术中，交易数据以电子记录的形式被永久储存下来，存放这些电子记录的文件我们称之为“区块”。In blockchain technology, transaction data is permanently stored in the form of electronic records, and the files storing these electronic records are called "blocks".
区块是按时间顺序一个个先后生成的，每一个区块记录有它在被创建期间发生的所有交易，所有区块汇总起来形成一个链式的记录合集。由于不同区块链网络中，节点的吞吐率不同，因此，在不同区块链网络中，区块的大小可能也不同。Blocks are generated one by one in chronological order, and each block records all transactions that occurred during its creation, and all blocks are aggregated to form a chain record collection. Due to the different throughput rates of nodes in different blockchain networks, the size of blocks may also be different in different blockchain networks.
交易(transaction)transaction
本申请涉及到的交易，是指用户通过任一节点创建，并发布数据至区块链的分布式数据库中的过程。The transaction involved in this application refers to the process that the user creates through any node and publishes the data to the distributed database of the blockchain.
该交易存在狭义的交易以及广义的交易之分。There are transactions in the narrow sense and transactions in the broad sense.
