[0001] This specification relates to the field of computer software technology, and in particular to a method, apparatus, electronic device, and storage medium for improving blockchain consensus efficiency. Background Technology

[0002] At the physical level, the transaction throughput of a blockchain network depends on the block production and packaging efficiency of nodes within the network. Many factors influence this efficiency. For example, verifying each transaction in the blockchain transaction list relies on the efficiency of broadcasting the transaction content. After block production and packaging, the consensus speed depends on whether the packaging node can broadcast the block quickly enough to other consensus nodes, allowing them to verify the new block. Therefore, improving the efficiency of blockchain consensus by enabling faster broadcasting of transactions or new blocks when selecting consensus nodes for transaction broadcasting or block production is a pressing technical problem.

[0036] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0037] The following section provides a detailed explanation of a blockchain consensus efficiency improvement scheme presented in this manual, using specific examples.

[0038] Example 1

[0039] This invention focuses on how to improve the efficiency of blockchain consensus by broadcasting transactions or new blocks more quickly when selecting consensus nodes for transaction broadcasting or block production. Generally, the transaction throughput of a blockchain network depends on the efficiency of the network nodes in packaging blocks at the physical level. Many factors influence block production, including the efficiency of broadcasting transaction content, which depends on the efficiency of each transaction in the block's transaction list. After a block is packaged, the consensus speed depends on whether the node that packaged the block has a sufficiently fast enough efficiency to broadcast it to other consensus nodes to achieve consensus on the new block. Therefore, if the blockchain network nodes can sort their consensus node list based on factors such as block propagation efficiency and consensus efficiency, the efficiency of block packaging and verification consensus can be improved to some extent. This principle can be compared to the PageRank principle of web search engines. When using a search engine, the results show that web pages with higher reputation rank higher in search results. A web page's reputation is calculated based on the number of times it is cited by other web pages and the reputation of the citing web pages themselves.

[0040] Therefore, the node ranking technology solution in this invention is used as the ranking basis for the node ranking table. The principle of node ranking is that the higher a node's reputation, the higher it is selected to send transactions / block broadcasts. Taking the PBFT consensus algorithm as an example, this algorithm requires the number of nodes participating in consensus voting to be approximately (2f+1) / (3f+1) of the total number of nodes, which is about 2 / 3. Therefore, as long as about 2 / 3 of the nodes can respond and process quickly, the network can be guaranteed to process transactions quickly and with high quality continuously. Figure 1 The illustration shows a method for improving blockchain consensus efficiency according to an embodiment of the present invention. When a node broadcasts a transaction or a new block, the order in which the nodes to which it is connected are sorted according to a dynamically maintained node reputation ranking table. The method includes:

[0041] S1: Based on reputation value, establish a node ranking table to sort multiple consensus nodes in the blockchain.

[0042] Optionally, the fields of the node ranking table include at least a unique identifier for the consensus node, a reputation score, and / or a sort number. Specifically, improving the consensus efficiency of a blockchain network cannot be achieved by improving the efficiency of a single node; therefore, all consensus nodes participating in the blockchain need to establish such a node ranking table.

[0043] S2: Determine the basis for scoring the reputation value of the current consensus node, and score the reputation values ​​of other consensus nodes connected to the current consensus node.

[0044] Optionally, the reputation score is based on factors including node connection response speed, failure rate, historical voting rate, staking token value, and / or other node scoring information. Specifically, the reputation score criteria need to be selected in conjunction with the specific consensus protocol. For example, when the consensus protocol is BFT, node connection response speed can be used as the scoring criterion; the faster the response speed, the higher the reputation score and the higher the ranking. When the consensus protocol is POW, historical voting rate can be used as the scoring criterion; the higher the historical voting rate, i.e., the more times a node participates in block production consensus voting, the higher the reputation score and the higher the ranking. When the consensus protocol is POS, staking token value can be used as the scoring criterion; the higher the staking token value, the higher the reputation score and the higher the ranking. Node failure rate and reference to other node scoring can also be used; for node failure rate, fewer failures result in a higher reputation score and a higher ranking. The scoring information for other nodes includes a node ranking table and the scoring criteria.

[0045] S3: Update the node ranking table of the current consensus node based on the reputation score.

[0046] Optionally, the node ranking table of the current consensus node is updated based on the reputation score, including a higher score for a higher ranking.

[0047] S4: Periodically send the scoring information of the current consensus node to other consensus nodes. The scoring information includes at least the node ranking table and the reputation score criteria. Specifically, the reason for periodically sending the node ranking table and reputation score criteria of the current consensus node to other consensus nodes is that the node's ranking table and scoring criteria can be provided as a reference to other nodes. If the receiving node and the sending node have the same consensus protocol, the same node performance, or are connected to the same or similar consensus nodes, they can refer to the sending node's node ranking table and scoring criteria. This can improve the efficiency of the node in calculating the node ranking table and save computing resources.

[0048] Optionally, the scoring information of the current consensus node is periodically sent to other consensus nodes, including sending the scoring information of the current consensus node when the current node initiates a connection heartbeat probe with other consensus nodes.

[0049] S5: Based on the node ranking table, determine the multiple consensus nodes that will participate in the consensus vote.

[0050] like Figure 2 As shown, another implementation of the blockchain consensus efficiency improvement method according to an embodiment of the present invention further includes:

[0051] S6: After a preset period, the current node clears its node ranking table so that it can rebuild the ranking table. Specifically, the ranking table lifecycle is set to periodicity. Each node's own ranking table reaches a certain block production cycle. This cycle can be used as a blockchain protocol parameter or as a node-defined configuration. For example, the ranking table is cleared after every n blocks are generated, so that newly added nodes have a fair chance to compete and avoid the possibility of centralized malicious activity caused by a fixed number of nodes producing blocks.

[0052] It should be noted that the solutions of this invention are applicable to peer-to-peer interconnected blockchain networks. Regardless of the design of the blockchain protocol's economic model or the choice of consensus algorithms for blockchain nodes, they can optimize the network layer. Thus, among all interconnected nodes in the network, those with higher reputation values ​​are prioritized for transaction processing, ensuring the quality of the communication network. Therefore, it should be understood that any application scenario that satisfies the solution of this invention by constructing a node ranking table and forming node ranking tables for each node based on the blockchain protocol and different consensus algorithms of different blockchain nodes conforms to the technical features and protection scope of this invention.
