Description

一种区块链数据的共识方法及相关设备A consensus method of blockchain data and related equipment

技术领域Technical field

本申请涉及区块链技术，尤其涉及一种区块链数据的共识方法及相关设备。This application relates to blockchain technology, and in particular to a consensus method of blockchain data and related equipment.

背景技术Background technique

区块链作为一种按时间顺序存储数据的数据结构，可支持不同的共识机制。共识机制是区块链技术的重要组件，区块链共识机制的目标是使所有的诚实节点保存一致的区块链视图。As a data structure that stores data in chronological order, blockchain can support different consensus mechanisms. The consensus mechanism is an important component of blockchain technology. The goal of the blockchain consensus mechanism is to make all honest nodes maintain a consistent view of the blockchain.

实用拜占庭容错***(PBFT，Practical Byzantine-Fault-Tolerant)是区块链中较为常用的一种共识算法，即服务作为状态机进行建模，状态机在分布式***的不同节点进行副本复制，每个状态机的副本都保存了服务的状态，同时也实现了服务的操作。Practical Byzantine-Fault-Tolerant (PBFT, Practical Byzantine-Fault-Tolerant) is a commonly used consensus algorithm in the blockchain, that is, the service is modeled as a state machine, and the state machine is replicated at different nodes in the distributed system. Each copy of the state machine saves the state of the service and also realizes the operation of the service.

PBFT算法的流程中，设定参与共识的节点总数为N＝3f+1，其中f为潜在的拜占庭(恶意)节点数量，以f＝1，即N＝4节点为例组成的共识网络，如图1所示。在该流程中，包括请求过程(request)、共识过程和响应过程(reply)，其中，共识过程分为pre-prepare、prepare、commit三个阶段，该共识过程具体如下：In the process of the PBFT algorithm, the total number of nodes participating in the consensus is set to N=3f+1, where f is the number of potential Byzantine (malicious) nodes, taking f=1, that is, N=4 nodes as an example of a consensus network, such as As shown in Figure 1. In this process, it includes a request process (request), a consensus process and a response process (reply). The consensus process is divided into three stages: pre-prepare, prepare, and commit. The consensus process is as follows:

从全网节点(节点C、节点0、节点1、节点2、节点3)选举出一个提议节点(节点C)，新区块由提议节点负责生成；其它节点把客户端发来的交易向全网广播，提议节点将从网络收集到需放在新区块内的多个交易排序后存入列表，并将该列表向全网广播；其它节点接收到交易列表后，根据排序模拟执行这些交易。所有交易执行完后，基于交易结果计算新区块的哈希摘要，并向全网广播；如果一个节点收到的2f条来自其它节点发来的摘要都和自己的相同，就向全网广播一条commit消息；如果一个节点收到2f+1条commit消息，即可提交新区块及其交易到本地的区块链和状态数据库，即确认新区块为合法区块。A proposal node (node C) is elected from the nodes of the whole network (node C, node 0, node 1, node 2, node 3), and the new block is generated by the proposal node; other nodes send the transaction sent by the client to the whole network Broadcast, the proposed node will collect multiple transactions that need to be placed in the new block from the network and store them in a list, and broadcast the list to the entire network; after receiving the transaction list, other nodes will execute these transactions according to the ranking simulation. After all transactions are executed, calculate the hash digest of the new block based on the transaction result and broadcast it to the entire network; if a node receives 2f digests from other nodes that are the same as its own, then broadcast one to the entire network Commit message; if a node receives 2f+1 commit messages, it can submit the new block and its transactions to the local blockchain and state database, that is, confirm that the new block is a legal block.

在上述流程描述中可以了解到，PBFT算法的通信复杂度较高，对于n个节点组成的区块链共识网络，每一轮共识过程需要O(n^2)次通信。对于同机房的少数节点组成的网络而言，高通信复杂度所导致的性能问题影响不大，但由于在很多场景下，区块链需要更多的节点参与才能更能体现出公信力和实用价值，因此存在节点数量增长的需求。实验表明，当PBFT算法应用在节点数量大于19的时候，性能会变得明显低下；当节点数量到达31时，共识算法将几乎无法正常工作。It can be understood from the above process description that the communication complexity of the PBFT algorithm is relatively high. For a blockchain consensus network composed of n nodes, each round of consensus process requires O(n^2) communications. For a network composed of a few nodes in the same computer room, the performance problems caused by high communication complexity have little impact, but because in many scenarios, the blockchain needs more nodes to participate in order to better reflect credibility and practical value , So there is a demand for an increase in the number of nodes. Experiments show that when the PBFT algorithm is applied to the number of nodes greater than 19, the performance will become significantly lower; when the number of nodes reaches 31, the consensus algorithm will almost not work properly.

在现有技术中，实用拜占庭容错***(PBFT，Practical Byzantine-Fault-Tolerant)是区块链中较为常用的一种共识算法，即服务作为状态机进行建模，状态机在分布式***的不同节点进行副本复制，每个状态机的副本都保存了服务的状态，同时也实现了服务的操作。PBFT算法的流程中，设定参与共识的节点总数为N＝3f+1，其中f为潜在的拜占庭(恶意)节点数量，以f＝1，即N＝4节点为例组成的共识网络，如图1所示。在该流程中，包括请求过程(request)、共识过程和响应过程(reply)，其中，共识过程分为pre-prepare、prepare、commit三个阶段，该共识过程具体如下：从全网节点(节点C、节点0、节点1、节点2、节点3)选举出一个提议节点(节点C)，新区块由提议节点负责生成；其它节点把客户端发来的交易向全网广播，提议节点将从网络收集到需放在新区块内的多个交易排序后存入列表，并将该列表向全网广播；其它节点接收到交易列表后，根据排序模拟执行这些交易。所有交易执行完后，基于交易结果计算新区块的哈希摘要，并向全网广播；如果一个节点收到的2f条来自其它节点发来的摘要都和自己的相同，就向全网广播一条commit消息；如果一个节点收到2f+1条commit消息，即可提交新区块及其交易到本地的区块链和状态数据库，即确认新区块为合法区块。在上述流程描述中可以了解到，PBFT算法的通信复杂度较高，对于n个节点组成的区块链共识网络，每一轮共识过程需要O(n^2)次通信。对于同机房的少数节点组成的网络而言，高通信复杂度所导致的性能问题影响不大，但由于在很多场景下，区块链需要更多的节点参与才能更能体现出公信力和实用价值，因此存在节点数量增长的需求。实验表明，当PBFT算法应用在节点数量大于19的时候，性能会变得明显低下；当节点数量到达31时，共识算法将几乎无法正常工作。为此，本申请实施例提供了一种区块链数据的共识方法及其相关设备，用于简化区块链的共识过程。In the prior art, Practical Byzantine-Fault-Tolerant (PBFT, Practical Byzantine-Fault-Tolerant) is a commonly used consensus algorithm in the blockchain, that is, the service is modeled as a state machine, which is different in distributed systems. The node performs copy replication, and each copy of the state machine saves the state of the service and also realizes the operation of the service. In the process of the PBFT algorithm, the total number of nodes participating in the consensus is set to N=3f+1, where f is the number of potential Byzantine (malicious) nodes, taking f=1, that is, N=4 nodes as an example of a consensus network, such as As shown in Figure 1. In this process, it includes a request process (request), a consensus process and a response process (reply). The consensus process is divided into three stages: pre-prepare, prepare, and commit. The consensus process is as follows: C. Node 0, node 1, node 2, node 3) elect a proposal node (node C), the new block is generated by the proposal node; other nodes will broadcast the transaction sent by the client to the whole network, and the proposal node will The network collects multiple transactions that need to be placed in the new block and stores them in a list, and broadcasts the list to the entire network; after other nodes receive the transaction list, they execute these transactions according to the sorting simulation. After all transactions are executed, calculate the hash digest of the new block based on the transaction result and broadcast it to the entire network; if a node receives 2f digests from other nodes that are the same as its own, then broadcast one to the entire network Commit message; if a node receives 2f+1 commit messages, it can submit the new block and its transactions to the local blockchain and state database, that is, confirm that the new block is a legal block. It can be understood from the above process description that the communication complexity of the PBFT algorithm is relatively high. For a blockchain consensus network composed of n nodes, each round of consensus process requires O(n^2) communications. For a network composed of a few nodes in the same computer room, the performance problems caused by high communication complexity have little impact, but because in many scenarios, the blockchain needs more nodes to participate in order to better reflect credibility and practical value , So there is a demand for the number of nodes to grow. Experiments show that when the PBFT algorithm is applied to the number of nodes greater than 19, the performance will become significantly lower; when the number of nodes reaches 31, the consensus algorithm will almost not work properly. To this end, the embodiments of the present application provide a blockchain data consensus method and related equipment to simplify the blockchain consensus process.

本实施例中，投票节点获取待确认区块。In this embodiment, the voting node obtains the block to be confirmed.

在一个区块生成周期中，区块链***中的众多节点将通过特定的算法选择出提议节点(Proposer)和投票节点(Validators，也称为验证人节点)，即在区块链中参与共识的角色包括两类：提议节点与投票节点，提议节点负责收集交易、打包区块和验证投票信息；投票节点负责验证区块和给有效的区块进行投票。本步骤中，投票节点可以通过区块链***中获取得到提议节点发送给该投票节点的待确认区块，也可以是接收提议节点发送的待确认消息进一步生成待确认区块，还可以是其他的获取方式，具体此处不做限定。In a block generation cycle, many nodes in the blockchain system will select proposal nodes (Proposer) and voting nodes (Validators, also known as validators) through specific algorithms, that is, participate in consensus in the blockchain There are two types of roles: the proposal node and the voting node. The proposal node is responsible for collecting transactions, packaging blocks and verifying voting information; the voting node is responsible for verifying blocks and voting for valid blocks. In this step, the voting node can obtain the block to be confirmed sent by the proposal node to the voting node through the blockchain system, or it can receive the message to be confirmed sent by the proposal node to further generate the block to be confirmed, or other The method of obtaining is not limited here.

202、投票节点对待确认区块进行投票；202. The voting node votes for the block to be confirmed;

本实施例中，投票节点可以使用聚合签名算法对待确认区块进行投票签名，得到签名信息。In this embodiment, the voting node can use the aggregate signature algorithm to vote and sign the block to be confirmed to obtain signature information.

具体的，该投票节点可以对该投票信息进行合法性验证，当该投票节点确定该投票信息通过合法性验证的时候，则该投票节点使用聚合签名算法对待确认区块进行投票签名，得到签名信息。Specifically, the voting node can verify the legality of the voting information. When the voting node determines that the voting information passes the legality verification, the voting node uses the aggregate signature algorithm to vote and sign the block to be confirmed to obtain the signature information .

此外，在本方案的实际应用过程中，可以使用常用的聚合签名算法参与其中，例如EC-Schnorr多重签名算法、BLS签名算法、Gamma签名算法或者是其他的聚合签名算法参与其中，此处不做限定。In addition, in the actual application process of this scheme, you can use common aggregate signature algorithms to participate in it, such as EC-Schnorr multi-signature algorithm, BLS signature algorithm, Gamma signature algorithm, or other aggregate signature algorithms. limited.

203、投票节点向提议节点发送签名信息；203. The voting node sends signature information to the proposing node;

本实施例中，投票节点在步骤202得到签名信息之后，将该签名信息发送至提议节点，以使得该提议节点得知该投票节点对该待确认区块进行投票，即得知该投票节点认可该待确认区块。In this embodiment, after obtaining the signature information in step 202, the voting node sends the signature information to the proposing node, so that the proposing node knows that the voting node has voted on the block to be confirmed, that is, knows that the voting node approves The block to be confirmed.

具体在方案的实施过程中，该签名信息还可以包括待确认区块的区块头的哈希值，其中，待确认区块的区块头的哈希值用于标识该签名信息对应的区块信息，即标识该签名信息与该待确认区块存在对应关系。Specifically, during the implementation of the solution, the signature information may also include the hash value of the block header of the block to be confirmed, where the hash value of the block header of the block to be confirmed is used to identify the block information corresponding to the signature information , That is, it indicates that the signature information has a corresponding relationship with the block to be confirmed.

204、提议节点判断是否达到预设值；204. The proposing node judges whether the preset value is reached;

本实施例中，提议节点判断接收到的所述签名信息的数量是否达到预设值，若是，则执行步骤205，若否，则执行步骤208。In this embodiment, the proposing node judges whether the quantity of the received signature information reaches a preset value, if so, execute step 205, and if not, execute step 208.

具体的，提议节点可以判断在预设时间段内接收到的该签名信息的数量是否达到预设值。Specifically, the proposing node can determine whether the number of signature information received within a preset time period reaches a preset value.

作为一个优选实施例，在这里可以引入PBFT算法的验证机制，即此处提议节点也可以作为投票节点进行参与投票，也可以不参与投票。具体判断过程可以借鉴PBFT算法的认证模式，即该区块链***中一共包括3F+1个节点，F为大于0的自然数以该提议节点参与投票为例，此时本步骤中的预设值为2F，即该提议节点在预设时间段内若接收到2F个节点确定对该待确认区块的签名信息时，即确定签名信息的数量达到预设值，则执行步骤205，若否，则执行步骤208。As a preferred embodiment, a verification mechanism of the PBFT algorithm can be introduced here, that is, the proposed node can also be used as a voting node to participate in voting, or not to participate in voting. The specific judgment process can refer to the authentication mode of the PBFT algorithm, that is, the blockchain system includes a total of 3F+1 nodes, and F is a natural number greater than 0. Take the proposed node to participate in voting as an example. At this time, the default value in this step is 2F, that is, if the proposal node receives 2F nodes within the preset time period to determine the signature information for the block to be confirmed, that is, it is determined that the number of signature information reaches the preset value, then step 205 is executed, if not, Step 208 is executed.

205、若是，则提议节点将签名信息进行聚合；205. If yes, propose that the node aggregate the signature information;

本实施例中，当提议节点在步骤204中确定接收到的所述签名信息的数量达到预设值时，则将该签名信息使用聚合签名算法进行聚合。In this embodiment, when the proposing node determines in step 204 that the quantity of the received signature information reaches a preset value, the signature information is aggregated using an aggregation signature algorithm.

具体的，本步骤与前述步骤202类似，不对聚合签名算法进行限制。具体在方案的执行过程中，可以以EC-Schnorr签名算法为例进行说明，请参阅图5中描述的EC-Schnorr算法实现流程，用户之间的交互可以抽象为4个步骤。第一步，签名节点发送承诺(Commitment)给聚合节点，如图中①所示；第二步，聚合节点发送挑战(Challenge)给签名节点，如图中②所示；第三步，签名节点根据挑战生成回应(Response)，如图中③所示；第四步，聚合节点根据签名节点的承诺及回应生成聚合签名，并且广播聚合签名给所有的签名验证节点，如图中④所示。聚合节点与签名节点之间的多次交互是为了确保每个签名节点是签名所对应公钥的拥有者，防止签名节点作恶。Specifically, this step is similar to the aforementioned step 202, and does not limit the aggregation signature algorithm. In the execution of the scheme, the EC-Schnorr signature algorithm can be taken as an example for description. Please refer to the implementation process of the EC-Schnorr algorithm described in Figure 5. The interaction between users can be abstracted into 4 steps. In the first step, the signing node sends a Commitment to the aggregation node, as shown in ① in the figure; in the second step, the aggregation node sends a challenge to the signing node, as shown in ② in the figure; the third step, the signing node According to the challenge, a response (Response) is generated, as shown in Figure ③; in the fourth step, the aggregation node generates an aggregate signature according to the commitment and response of the signature node, and broadcasts the aggregate signature to all signature verification nodes, as shown in Figure ④. The multiple interactions between the aggregation node and the signature node are to ensure that each signature node is the owner of the public key corresponding to the signature and prevent the signature node from doing evil.

206、提议节点发送聚合签名至投票节点；206. The proposing node sends the aggregate signature to the voting node;

本实施例中，提议节点在步骤205得到该聚合签名之后，将该聚合签名发送至投票节点。In this embodiment, after obtaining the aggregate signature in step 205, the proposing node sends the aggregate signature to the voting node.

207、投票节点确定聚合签名有效；207. The voting node determines that the aggregate signature is valid;

本实施例中，当投票节点确定该聚合签名通过合法性验证时，则确定所述待确认区块有效。In this embodiment, when the voting node determines that the aggregated signature passes the legality verification, it is determined that the block to be confirmed is valid.

具体的，此处仍以PBFT为例，当该投票节点收到该聚合签名之后，并验证此聚合签名包含针对当前区块的来自2F+1个节点的合法多重签名，即可认定该待确认区块有效，后续可以提交新区块及其交易到本地的区块链、更新状态数据库或者将该带投票信息添加入交易池排队等待交易等，具体此处不做限定。Specifically, here is still taking PBFT as an example. When the voting node receives the aggregated signature and verifies that the aggregated signature contains legal multi-signatures from 2F+1 nodes for the current block, it can be determined to be confirmed The block is valid, and you can subsequently submit a new block and its transaction to the local blockchain, update the status database, or add the voting information to the transaction pool to wait for the transaction, etc. The specifics are not limited here.

208、若否，则提议节点执行其他操作。208. If not, propose the node to perform other operations.

本实施例中，当该提议节点在步骤204中确定接收到的所述签名信息的数量未达到预设值时，则执行其他操作，即确定该待确认区块未获得区块链***的认可，则该提议节点不执行根据签名信息生成聚合签名的步骤，可直接将该待确认区块进行丢弃，或者是重新提交等待下一轮询过程，还可以是其他的操作，具体此处不做限定。In this embodiment, when the proposing node determines in step 204 that the quantity of the received signature information does not reach the preset value, other operations are performed, that is, it is determined that the block to be confirmed has not been approved by the blockchain system , The proposing node does not perform the step of generating an aggregated signature based on the signature information, and can directly discard the block to be confirmed, or resubmit and wait for the next polling process, or other operations, which are not specifically done here limited.

本实施例中，提议节点接收所述多个投票节点分别发送的签名信息，所述签名信息包括所述投票节点对待确认区块的签名；判断接收到的所述签名信息的数量是否达到预设值；若是，则利用接收到的多个所述签名信息聚合生成聚合签名；将所述聚合签名发送至所述投票节点，以使得当所述投票节点对所述聚合签名通过验证时确定所述待确认区块有效。因此，在区块链的共识过程中生成聚合签名，可以将来自各个投票节点的签名投票进行聚合，简化区块链的共识过程，可以对更多的数据进行共识，从而降低网络中发生阻塞的风险。In this embodiment, the proposing node receives the signature information sent by the multiple voting nodes, the signature information includes the signature of the block to be confirmed by the voting node; it is judged whether the amount of the received signature information reaches a preset value Value; if so, use the multiple received signature information to aggregate to generate an aggregate signature; send the aggregate signature to the voting node, so that when the voting node passes the verification of the aggregate signature, it is determined that the The block to be confirmed is valid. Therefore, generating aggregated signatures in the consensus process of the blockchain can aggregate the signature votes from various voting nodes, simplify the consensus process of the blockchain, and achieve consensus on more data, thereby reducing congestion in the network. risk.

具体可参阅图4的共识流程，从全网节点选举出一个提议节点，新区块由提议节点负责生成。图中节点0为提议节点，其他节点为投票节点。For details, please refer to the consensus process in Figure 4. A proposal node is elected from the nodes of the entire network, and the new block is generated by the proposal node. In the figure, node 0 is a proposal node, and other nodes are voting nodes.

投票节点把客户端发来的交易向全网广播，提议节点将从网络收集到需放在新区块内的多个交易排序后存入列表，并将该列表向全网广播。投票节点接收到交易列表后，根据排序模拟执行这些交易。所有交易执行完后，用自己的私钥对待确认的区块进行签名，然后将签名返回给提议节点。提议节点验证接收到的区块投票签名，如果提议节点收到超过2f个节点的合法签名，则通过多重签名聚合算法，连同自己对区块的签名一起，将签名聚合生成一个多重签名。如果一个节点收到多重签名消息，并验证此多重签名消息包含针对当前区块的来自2f+1个节点的合法多重签名，即可提交新区块及其交易到本地的区块链和状态数据库。The voting node broadcasts the transaction sent by the client to the entire network. The proposed node will collect multiple transactions that need to be placed in the new block from the network and store it in a list, and broadcast the list to the entire network. After the voting node receives the transaction list, it executes these transactions according to the ranking simulation. After all transactions are executed, use your private key to sign the block to be confirmed, and then return the signature to the proposing node. The proposing node verifies the received block voting signatures. If the proposing node receives legal signatures from more than 2f nodes, it will use the multi-signature aggregation algorithm to aggregate the signatures together with its own signature on the block to generate a multi-signature. If a node receives a multi-signature message and verifies that this multi-signature message contains legal multi-signatures from 2f+1 nodes for the current block, it can submit the new block and its transactions to the local blockchain and state database.

本申请实施例中，基于图2所述实施例，具体在步骤201投票节点获取待确认区块的过程可以是通过提议节点来实现。下面请参阅图3，本申请实施例一种区块链数据的共识方法的另一个实施例中，基于图2所述实施例，具体在步骤201的执行过程可以包括：In the embodiment of the present application, based on the embodiment described in FIG. 2, the process of obtaining the block to be confirmed by the voting node in step 201 may be implemented by the proposal node. Please refer to Figure 3 below.

301、投票节点获取交易信息；301. Voting nodes obtain transaction information;

本实施例中，投票节点获取交易信息，即各个投票节点获取自身客户端所生成的交易信息。In this embodiment, the voting nodes obtain transaction information, that is, each voting node obtains transaction information generated by its own client.

302、投票节点向提议节点发送交易信息；302. The voting node sends transaction information to the proposal node;

本实施例中，各个投票节点将获取得到的交易信息发送至提议节点，例如，各个投票节点可以通过区块链网络广播的形式进行发送，也可以是直接点对点发送模式进行发送，具体此处不做限定。In this embodiment, each voting node sends the obtained transaction information to the proposal node. For example, each voting node can send it in the form of a blockchain network broadcast, or it can be sent in a direct point-to-point sending mode. Make a limit.

本实施例中，提议节点对在步骤302收集到的交易信息进行排序，得到交易列表。In this embodiment, the proposing node sorts the transaction information collected in step 302 to obtain a transaction list.

作为一个优选实施例，具体在图3对应实施例中引入交易列表之后，步骤205中，当提议节点在步骤204中确定接收到的所述签名信息的数量达到预设值时，则将该签名信息使用聚合签名算法进行聚合，得到聚合签名的过程具体可以将该交易列表引入聚合签名中。As a preferred embodiment, specifically after introducing the transaction list in the embodiment corresponding to FIG. 3, in step 205, when the proposing node determines in step 204 that the quantity of the received signature information reaches the preset value, the signature Information is aggregated using an aggregate signature algorithm, and the process of obtaining an aggregate signature can specifically incorporate the transaction list into the aggregate signature.

具体地，该提议节点模拟执行所述交易列表，得到交易结果；根据所述交易结果生成待确认区块之后，该提议节点对所述待确认区块进行签名，得到第一签名，从而，步骤204中利用接收到的多个所述签名信息聚合生成聚合签名具体包括：将该提议节点的第一签名与步骤203接收到的多个签名信息进行聚合，得到聚合签名。Specifically, the proposing node simulates the execution of the transaction list to obtain the transaction result; after generating the block to be confirmed according to the transaction result, the proposing node signs the block to be confirmed to obtain the first signature, so that the step Aggregating and generating an aggregate signature by using the plurality of received signature information in 204 specifically includes: aggregating the first signature of the proposing node with the multiple signature information received in step 203 to obtain the aggregate signature.

本实施例中，投票节点按照标准流程模拟执行该交易列表，生成交易结果。In this embodiment, the voting node simulates the execution of the transaction list according to the standard process, and generates the transaction result.

306、投票节点生成待确认区块。306. The voting node generates a block to be confirmed.

本实施例中，投票节点根据步骤305得到的交易结果生成待确认区块。In this embodiment, the voting node generates a block to be confirmed according to the transaction result obtained in step 305.

举例来说，待确认区块可以是待确认的区块，该区块中包含上述交易列表中的全部交易；For example, the block to be confirmed may be a block to be confirmed, and the block contains all the transactions in the above transaction list;

本实施例中，具体在方案的执行过程中，投票节点在步骤304获取得到的交易排序列表还包括历史区块信息，还可以增加对步骤305的执行前提条件的判断步骤，下面请参阅图3-1，具体增加的步骤包括：In this embodiment, specifically during the execution of the solution, the transaction ranking list obtained by the voting node in step 304 also includes historical block information, and a judgment step for the execution preconditions of step 305 can also be added. Please refer to Figure 3 below. -1, the specific additional steps include:

307、使用自身数据库判断是否存在与所述历史区块消息匹配的目标数据；307. Use its own database to determine whether there is target data matching the historical block message;

本实施例中，该投票节点使用自身数据库判断历史区块消息是否存在与所述历史区块消息匹配的目标数据，若是，则执行步骤308，若否，则执行步骤309。In this embodiment, the voting node uses its own database to determine whether the historical block message has target data that matches the historical block message, if yes, execute step 308, and if not, execute step 309.

具体的，该历史区块信息可以为历史区块的全部信息，也可以是历史区块全部信息的哈希值，作为一个优选方案，为了节省网络资源，该历史区块信息还可以是该提议节点数据库中最新n(n为大于0的整数)个区块的哈希值，作为一个优选方案，该历史区块信息可以以区块头的形式存在加载在该交易排序列表信息中，还可以是其他类型的历史区块信息，具体此处不做限定。Specifically, the historical block information can be all the information of the historical block or the hash value of all the information of the historical block. As a preferred solution, in order to save network resources, the historical block information can also be the proposal The hash value of the latest n (n is an integer greater than 0) blocks in the node database. As a preferred solution, the historical block information can be stored in the transaction ranking list information in the form of a block header, or it can be Other types of historical block information are not specifically limited here.

308、若存在，则触发所述根据所述交易结果生成待确认区块。308. If it exists, trigger the generation of the block to be confirmed according to the transaction result.

本实施例中，当投票节点确定自身数据库中存在与所述历史区块信息匹配的目标数据时，则触发执行步骤306根据所述交易结果生成待确认区块。In this embodiment, when the voting node determines that there is target data matching the historical block information in its database, it triggers the execution of step 306 to generate a block to be confirmed according to the transaction result.

具体的，如果投票节点发现待确认区块的历史区块信息中的哈希值与自身数据库中之前的区块是否匹配，若匹配，则说明该投票节点与该提议节点的区块高度一致，可以执行后续的共识流程。Specifically, if the voting node finds whether the hash value in the historical block information of the block to be confirmed matches the previous block in its own database, if it matches, it means that the block of the voting node and the proposed node are highly consistent. The follow-up consensus process can be executed.

309、若不存在，则执行其他操作。309. If it does not exist, perform other operations.

本实施例中，当该投票节点确定自身数据库中不存在与所述历史区块信息匹配的目标数据时，则该投票节点执行其他操作，示例性地，该投票节点可以检查区块高度，如果历史区块信息中的区块高度高于自身数据库中对应的区块高度，那么首先要同步区块；如果不高于自己，那么就不会进行投票。In this embodiment, when the voting node determines that there is no target data matching the historical block information in its database, the voting node performs other operations. Illustratively, the voting node can check the block height, if If the block height in the historical block information is higher than the corresponding block height in the own database, the block must be synchronized first; if it is not higher than yourself, then no voting will be performed.

本申请实施例中，基于图3-1所述实施例，具体在步骤207确定所述待确认区块有效之后，则确定所述自身数据库中的目标数据有效，即该投票节点可以确定自身数据库中与历史区块信息匹配的目标数据也是有效区块。In the embodiment of this application, based on the embodiment described in Fig. 3-1, specifically after the block to be confirmed is determined to be valid in step 207, it is determined that the target data in the own database is valid, that is, the voting node can determine its own database The target data matching the historical block information is also a valid block.

本方案中基于多重签名的共识算法与传统的PBFT算法不同的另一个点在于本方案的共识算法需要一个额外的区块确认前一个区块的绝对一致性。由于网络中消息有丢失或其他异常攻击的情况，单一一轮的共识存在在不同节点之间存在不一致的可能，但对于连续的两个通过共识的区块，在后面的区块达成共识的时候就可以意味着在它之前的区块可以在网络中确认绝对一致，因此共识算法的安全性依然可以得到保证。Another difference between the multi-signature-based consensus algorithm in this solution and the traditional PBFT algorithm is that the consensus algorithm in this solution requires an additional block to confirm the absolute consistency of the previous block. Due to the loss of messages or other abnormal attacks in the network, a single round of consensus may be inconsistent between different nodes, but for two consecutive blocks that pass the consensus, a consensus is reached in the following block Time can mean that the block before it can be confirmed absolutely consistent in the network, so the security of the consensus algorithm can still be guaranteed.
