This embodiment includes one main chain, which is defined as a wide area network. The wide area network includes all nodes of the blockchain network; this embodiment also includes multiple A side chain is defined as a local area network that contains at least two nodes that conduct private transactions.
当区块链网络中需要建立局域网时，广域网的第一节点创建成员清单，成员清单中包含成员第二节点及第三节点。利用第二节点及第三节点的公钥对创建的成员清单加密形成消息体，将加密后的消息体在广域网进行广播。广域网所有成员收到广播的消息体即可获知第一节点的创建请求，但由于消息体是利用第二节点及第三节点的公钥进行了加密，因此只有第二节点和第三节点才能解开请求内容进而查看到清单列表获知成员清单中包含的成员，其他节点将忽略该请求，只做记录。第二节点和第三节点查看成员清单并同意后，确认和清单中的所有成员缔结联盟，形成局域网。具体的，以第二节点为例：第二节点通过解密广播的消息体获知创建请求，并同意加入与第三节点创建的局域网，将同意加入局域网的请求提交给第一节点，第一节点收到第二节点的同意请求以后，将第二节点的同意请求追加到局域网账本中，并且将账本同步给第二节点。最终，局域网账本中将包含第一节点，第二节点，第三节点成员的同意请求，局域网创建完成。反之，如果第二节点，第三节点中有成员不同意，该局域网将无效，进行删除，因为后续的所有背书都会失败，则局域网创建失败。此外，第一节点在发送广播后，通过广域网的CA中心签发证书，该证书将作为局域网的根证书。When a local area network needs to be established in the blockchain network, the first node of the WAN creates a member list, and the member list includes the second node and the third node of the member. The created member list is encrypted with the public keys of the second node and the third node to form a message body, and the encrypted message body is broadcast on the wide area network. All members of the WAN can know the creation request of the first node after receiving the broadcast message body. However, since the message body is encrypted with the public keys of the second node and the third node, only the second node and the third node can decode the request. Open the request content and then view the list list to learn the members included in the member list. Other nodes will ignore the request and only record. After the second node and the third node check the list of members and agree, they confirm to form an alliance with all the members in the list to form a local area network. Specifically, take the second node as an example: the second node learns the creation request by decrypting the broadcast message body, agrees to join the local area network created with the third node, submits the request for agreeing to join the local area network to the first node, and the first node receives the request. After the consent request of the second node is received, the consent request of the second node is added to the local area network ledger, and the ledger is synchronized to the second node. Finally, the LAN ledger will contain the consent requests of the first node, the second node, and the third node members, and the LAN creation is completed. Conversely, if there are members in the second node and the third node who disagree, the local area network will be invalid and will be deleted, because all subsequent endorsements will fail, and the local area network will fail to be created. In addition, after sending the broadcast, the first node issues a certificate through the CA center of the WAN, and the certificate will be used as the root certificate of the local area network.
在创建完局域网后，为局域网安装对应的智能合约。本实施例中的智能合约包含两种类型：局域网智能合约、广域网智能合约，局域网的智能合约与广域网的智能合约是独立的智能合约。安装在局域网中的智能合约，交易对手只能包含局域网成员列表中的成员。智能合约必须包含该合约适用的网段编码，一份智能合约不能同时安装在多个网段中。因此，针对创建的局域网，选择预先设定好的局域网类型的智能合约，并根据预先设定的网段编码与智能合约的映射关系，选择与创建的局域网的网段编码相对应的智能合约。After creating the local area network, install the corresponding smart contract for the local area network. The smart contracts in this embodiment include two types: local area network smart contracts and wide area network smart contracts. The local area network smart contracts and the wide area network smart contracts are independent smart contracts. For smart contracts installed in the local area network, the counterparty can only include members in the local area network member list. A smart contract must contain the applicable network segment code for the contract. A smart contract cannot be installed in multiple network segments at the same time. Therefore, for the created local area network, select the smart contract of the preset local area network type, and select the smart contract corresponding to the network segment code of the created local area network according to the mapping relationship between the preset network segment code and the smart contract.
当区块链网络中发起交易请求时，分析交易请求是在广域网中进行还是在创建好的局域网中进行，并将交易请求发送到对应的广域网或局域网中。若交易请求是在广域网中进行，则在广域网中运行广域网智能合约来进行对账本的读写操作，在广域网中运行智能合约和传统的区块链运行智能合约相同，在此不作赘述。When a transaction request is initiated in the blockchain network, analyze whether the transaction request is made in the WAN or in the created local area network, and send the transaction request to the corresponding WAN or local area network. If the transaction request is made in the WAN, the WAN smart contract is run in the WAN to perform the read and write operations of the ledger. Running the smart contract in the WAN is the same as running the smart contract in the traditional blockchain, so I will not go into details here.
若交易请求是在局域网中进行，则在局域网中运行该局域网对应的智能合约来进行对账本的读写操作。具体的，首先在创建好的局域网中各个节点例如第一节点、第二节点及第三节点相互通信后，在各个节点之间进行背书处理，局域网中各个节点将背书结果和该交易请求的交易内容或交易内容中的交易摘要按照预先设定好的相同的格式提交给主链即广域网，广域网对每个交易请求进行验证。验证通过后，广域网获取局域网中各个节点发送的交易内容中的交易摘要，并基于该交易摘要形成第一交易区块追加到广域网账本中，同时，反馈该第一交易区块相关信息至局域网中，该第一交易区块相关信息作为验证通过反馈信息，以反馈“已生成主链区块”的结果给局域网。局域网收到广域网反馈的“已生成主链区块”消息后，确认本次交易验证通过，并根据本次交易内容形成第二交易区块，将第一交易区块相关信息加入至第二交易区块中，最后将第二交易区块追加到局域网账本中，从而成功完成本次交易。具体的，在基于该交易摘要形成第一交易区块时，可对交易摘要进行哈希计算，将计算的结果作为一次新的交易形成广域网的区块，并将该区块以及本次交易请求的局域网编码形成交易体追加到广域网账本中。同时，计算形成的广域网的区块的哈希值，将该哈希值返回给局域网中各个节点，以反馈“已生成主链区块”的结果给局域网。局域网收到广域网反馈的“已生成主链区块”消息后，确认本次交易成功，并将计算的广域网的区块的哈希值作为本次交易的一部分，追加到局域网的交易体中，同时重新计算本次交易的hash，将该交易体追加到局域网账本中。If the transaction request is made in the local area network, the smart contract corresponding to the local area network is run in the local area network to read and write the account book. Specifically, first, after each node in the created local area network, such as the first node, the second node and the third node, communicates with each other, endorsement processing is performed between each node, and each node in the local area network will endorse the result and the transaction requested by the transaction. The transaction summary in the content or transaction content is submitted to the main chain, namely the WAN, in the same format as preset, and the WAN verifies each transaction request. After the verification is passed, the WAN obtains the transaction summary in the transaction content sent by each node in the local area network, and forms a first transaction block based on the transaction summary and appends it to the WAN ledger, and at the same time, feeds the relevant information of the first transaction block to the local area network. , the relevant information of the first transaction block is used as the verification feedback information to feed back the result of "the main chain block has been generated" to the local area network. After the LAN receives the "main chain block has been generated" message from the WAN, it confirms that the transaction verification is passed, and forms a second transaction block according to the content of this transaction, and adds the relevant information of the first transaction block to the second transaction. block, and finally append the second transaction block to the LAN ledger, thus successfully completing the transaction. Specifically, when the first transaction block is formed based on the transaction summary, a hash calculation can be performed on the transaction summary, the result of the calculation can be used as a new transaction to form a block of the WAN, and the block and the current transaction request The local area network code of the form transaction body is appended to the WAN ledger. At the same time, the hash value of the formed WAN block is calculated, and the hash value is returned to each node in the local area network to feed back the result of "the main chain block has been generated" to the local area network. After the LAN receives the "Main chain block has been generated" message from the WAN, it confirms that the transaction is successful, and adds the calculated hash value of the WAN block to the transaction body of the LAN as part of this transaction. At the same time, the hash of this transaction is recalculated, and the transaction body is added to the LAN ledger.
其中，广域网对每个交易请求进行验证的具体过程如下：(1)、重新计算每个交易请求的hash，判断局域网的每个请求的hash是否正确；(2)、读取局域网创建时定义好的交易策略，验证交易请求是否符合该定义好的交易策略。Among them, the specific process of verifying each transaction request by the WAN is as follows: (1), recalculate the hash of each transaction request, and judge whether the hash of each request of the local area network is correct; (2), read the definition when the local area network is created The transaction strategy is verified to verify whether the transaction request conforms to the defined transaction strategy.
这样，通过上述方案，在局域网中交易完成以后，主链即广域网中只记录了交易摘要，并没有存储完整的交易体内容，保证了信息的安全。同时，侧链即局域网脱离主链无法单独运行，也无法单独完成交易，保证了安全。In this way, through the above scheme, after the transaction is completed in the local area network, only the transaction summary is recorded in the main chain, that is, the wide area network, and the complete transaction body content is not stored, which ensures the security of information. At the same time, the side chain, that is, the local area network, cannot run independently from the main chain, nor can it complete transactions alone, ensuring security.
本实施例通过区块链网络中所有节点来搭建组成广域网，在广域网中第一节点请求与第二节点、第三节点进行私密交易时，创建由所述第一节点与第二节点、第三节点组成的局域网，并根据预先设定的网段编码与智能合约的映射关系，确定出与创建的局域网的网段编码相对应的智能合约，从而在创建的局域网中运行确定出的智能合约来对账本进行读写操作，完成所述第一节点与第二节点、第三节点的交易。由于是通过基于区块链网络搭建单广域网和多局域网，将需要进行私密交易的部分节点如第一节点与第二节点、第三节点加入至局域网中来完成交易，而不是直接在整个区块链网络中完成交易，因此，不是区块链网络中的每个成员节点都有包含该部分节点私密交易内容的完整交易账本，从而降低了该部分节点私密交易内容的泄露风险，提高了区块链网络中部分节点交易的安全性。In this embodiment, all nodes in the blockchain network are used to construct a wide area network. When the first node requests to conduct private transactions with the second node and the third node in the wide area network, the creation of a network consisting of the first node and the second node and the third node The local area network composed of nodes, and according to the mapping relationship between the preset network segment code and the smart contract, determine the smart contract corresponding to the network segment code of the created local area network, so as to run the determined smart contract in the created local area network. Read and write operations are performed on the ledger to complete the transaction between the first node, the second node, and the third node. Since a single wide area network and multiple local area networks are built based on the blockchain network, some nodes that need to conduct private transactions, such as the first node, the second node, and the third node, are added to the local area network to complete the transaction, rather than directly in the entire block. Therefore, not every member node in the blockchain network has a complete transaction ledger containing the private transaction content of this part of the node, thereby reducing the risk of leakage of the private transaction content of this part of the node and improving the block chain. The security of some node transactions in the chain network.

本实施例通过区块链网络中所有节点来搭建组成广域网，在广域网中第一节点请求与第二节点、第三节点进行私密交易时，创建由所述第一节点与第二节点、第三节点组成的局域网，并根据预先设定的网段编码与智能合约的映射关系，确定出与创建的局域网的网段编码相对应的智能合约，从而在创建的局域网中运行确定出的智能合约来对账本进行读写操作，完成所述第一节点与第二节点、第三节点的交易。由于是通过基于区块链网络搭建单广域网和多局域网，将需要进行私密交易的部分节点如第一节点与第二节点、第三节点加入至局域网中来完成交易，而不是直接在整个区块链网络中完成交易，因此，不是区块链网络中的每个成员节点都有包含该部分节点私密交易内容的完整交易账本，从而降低了该部分节点私密交易内容的泄露风险，提高了区块链网络中部分节点交易的安全性。In this embodiment, all nodes in the blockchain network are used to construct a wide area network. When the first node requests to conduct private transactions with the second node and the third node in the wide area network, the creation of a network consisting of the first node and the second node and the third node The local area network composed of nodes, and according to the mapping relationship between the preset network segment code and the smart contract, determine the smart contract corresponding to the network segment code of the created local area network, so as to run the determined smart contract in the created local area network.

Therefore, not every member node in the blockchain network has a complete transaction ledger containing the private transaction content of this part of the node, thereby reducing the risk of leakage of the private transaction content of this part of the node and improving the block chain. The security of some node transactions in the chain network.
进一步的，在一可选的实施例中，如图4所示，图4为本发明基于区块链的交易方法一实施例中局域网各节点的背书及验证示意图。例如，创建好的局域网中各个节点包括A1、A2、A3节点，在局域网的A1、A2、A3节点之间进行背书处理。其中，主链和侧链网络可达，侧链每个节点A1、A2、A3节点将背书结果和交易内容，按照相同的格式提交给主链。主链对每个交易请求进行验证。验证过程如下：Further, in an optional embodiment, as shown in FIG. 4 , FIG. 4 is a schematic diagram of endorsement and verification of each node of the local area network in an embodiment of the blockchain-based transaction method of the present invention. For example, each node in the created local area network includes A1, A2, and A3 nodes, and endorsement processing is performed between A1, A2, and A3 nodes in the local area network. Among them, the main chain and the side chain network are reachable, and each node A1, A2, A3 of the side chain submits the endorsement result and transaction content to the main chain in the same format. The main chain verifies each transaction request. The verification process is as follows:
(1)、重新计算每个交易请求的hash，判断侧链的每个请求的hash是否正确；(1) Recalculate the hash of each transaction request to determine whether the hash of each request of the side chain is correct;
(2)、读取侧链创建时定义好的交易策略，验证交易请求是否符合该定义好的交易策略。(2) Read the transaction strategy defined when the side chain was created, and verify whether the transaction request conforms to the defined transaction strategy.
如图5所示，图5为本发明基于区块链的交易方法一实施例中第一交易区块的生成示意图。主链将侧链提交的交易内容中的交易摘要进行hash计算，将计算的结果，作为一次新的交易，形成主链的区块即第一交易区块。将该第一交易区块追加到主链中。交易体中还包含了本次交易的侧链编码。同时，将结果反馈给侧链，作为侧链验证的一个环节，以反馈“已生成主链区块”的结果给局域网。As shown in FIG. 5 , FIG. 5 is a schematic diagram of generating a first transaction block in an embodiment of the blockchain-based transaction method of the present invention. The main chain performs hash calculation on the transaction summary in the transaction content submitted by the side chain, and uses the calculation result as a new transaction to form the block of the main chain, the first transaction block. Append the first transaction block to the main chain. The transaction body also contains the side chain code of this transaction. At the same time, the result is fed back to the side chain, as a part of the side chain verification, to feed back the result of "the main chain block has been generated" to the local area network.
如图6所示，图6为本发明基于区块链的交易方法一实施例中第二交易区块的生成示意图。侧链除了内部成员之间的策略需要满足以外，还需要得到主链“已生成主链区块”的消息后，才认为本次交易成功。将主链提交的第一交易区块的hashcode即主哈希码作为交易的一部分，追加到交易体中，同时重新计算该次交易的hash即交易哈希值，将该交易追加到侧链中，形成第二交易区块。As shown in FIG. 6 , FIG. 6 is a schematic diagram of generating a second transaction block in an embodiment of the blockchain-based transaction method of the present invention. In addition to satisfying the strategy between internal members, the side chain also needs to get the message that the main chain "main chain block has been generated" before the transaction is considered successful. The hashcode of the first transaction block submitted by the main chain, that is, the main hash code, is added to the transaction body as part of the transaction. At the same time, the hash of the transaction, that is, the transaction hash value, is recalculated, and the transaction is added to the side chain. , forming the second transaction block.
如前所述，交易完成以后，主链中只记录了交易的摘要，并没有存储完整的交易体内容，保证了信息的安全。同时，侧链虽然节点少，但是能得到整个主链的支撑，降低了攻击的可能。而且，侧链脱离主链后，由于无法得到主链的“已生成主链区块”的消息反馈，所以，侧链脱离主链无法单独运行即无法完成交易，保证了安全。As mentioned above, after the transaction is completed, only the summary of the transaction is recorded in the main chain, and the complete transaction body content is not stored, which ensures the security of information. At the same time, although the side chain has fewer nodes, it can be supported by the entire main chain, reducing the possibility of attacks. Moreover, after the side chain is separated from the main chain, since the message feedback of the "main chain block has been generated" of the main chain cannot be obtained, the side chain cannot operate independently from the main chain, that is, the transaction cannot be completed, ensuring security.
