In a distributed cloud computing environment, program modules can be located on local or remote computing system storage media including storage devices.

[0032] Figure 1 is a flowchart of a node processing method based on blockchain provided by an exemplary embodiment of the present disclosure. This embodiment can be applied on a blockchain network, such as Figure 1 As shown, the following steps are included:

[0033] Step S100, obtaining block information of the blockchain corresponding to the blockchain network.

[0034] The blockchain network may include multiple nodes, any of which may be a computing device in the blockchain network, such as a laptop, desktop computer, mobile phone, server, etc. In one embodiment, a node in the blockchain network may be a consensus node, which may be used to generate blocks (outgoing blocks) and perform consensus voting on blocks.

[0035] The block information includes: block information, block voting information and indicator information of each block in the blockchain. Among them, each block in the block information is a block that has passed consensus. The block information of each block can be used to indicate the information of generating the block and the process of putting the block on the chain; the voting information of each block is used to indicate the information of the block voted by consensus during the process of putting the block on the chain; the indicator information of each block is used to indicate the information included in the block. In one embodiment, the indicator information of each block includes at least one of the number of transactions in the block, the sum of transaction fees (Gas), and the number of accounts.

[0036] Step S110, based on the block generation information, block generation voting information and indicator information of each block, the contribution quantification information corresponding to the multiple nodes is determined.

[0037] The contribution quantification information is used to represent the quantitative data of the contribution of multiple nodes to the blockchain network. The quantitative data of the contribution of each node can be the value corresponding to the enthusiasm of the node's on-chain behavior in the blockchain network.

[0038] In one embodiment, the contribution quantification information may include the quantified data of each node. The quantified data of the contribution of the node can be determined by the indicator information of the blocks generated by the node, the number of generated blocks, and the on-chain behaviors such as voting for blocks. Exemplarily, the number of blocks generated by each node, the number of votes for voting for blocks, and the number of transactions in the generated blocks can be determined based on the block information, block voting information, and indicator information of each block, and then the sum of the number of blocks generated by the node, the number of votes for voting for blocks, and the number of transactions in the generated blocks is determined as the quantified data of the contribution of the node.

[0039] Step S120: Determine contribution information of each node among the multiple nodes to the blockchain network based on the contribution quantification information.

[0040] Among them, the contribution information of the node is used to indicate the degree of initiative of the node's on-chain behavior in the blockchain network. On-chain behavior may include, for example, at least one of the following: generating blocks (block generation), voting on block consensus, processing transactions, etc. The contribution information of the node is proportional to the degree of initiative of the node's on-chain behavior. Exemplarily, the contribution information of each node may include the contribution value of the node to the blockchain network; the higher the contribution value of the node, the higher the initiative of the node's on-chain behavior in the blockchain network. For example, the higher the contribution value of the node, it may indicate that the node generates more blocks, participates more in consensus voting on blocks, and / or generates higher indicator information in the blocks, etc.

[0041] Exemplarily, the quantified data of the contribution of each node in the contribution quantification information may be determined as the contribution information of the node.

[0042] Step S130, based on the contribution information of each node, determine the weight information of each node in processing blockchain transactions.

[0043] Among them, blockchain things can be used to represent related things corresponding to the blockchain network. Exemplarily, blockchain things can include the distribution of benefits generated by the blockchain, for example, creating a correspondence between preset contribution information and weight information, in which the contribution information is proportional to the benefit information, that is, the higher the benefit information, the greater the corresponding weight information. The weight information of each node can be determined based on the correspondence between the preset contribution information and the weight information, as well as the contribution information of each node. In this example, the block thing is used as an example of benefit distribution. The higher the weight information of the node, the higher the benefit that can be allocated to the node.

[0044] In the embodiments of the present disclosure, by converting the block generation information, block generation voting information and indicator information of each block into contribution quantification information, and determining the contribution information of each node through the quantification information, the contribution information of each node can be determined by comprehensively considering the block generation voting information and block generation information of each node in the blockchain network, as well as the indicator information of the generated block, thereby achieving the quantification of the node contribution information and making the contribution information more accurate and objective.

[0045] Figure 2 is a flow chart of step S110 provided by an exemplary embodiment of the present disclosure. In some optional implementations, such as Figure 2 As shown, step S110 in the embodiment of the present disclosure may include the following steps:

[0046] Step S111, determining the node interaction matrix according to the block generation information, block generation voting information and indicator information of each block.

[0047] The size of the node interaction matrix is ​​N×N, where N is the number of nodes in the blockchain network and N is an integer greater than or equal to 0.

[0048] In one implementation, the value corresponding to each element in the node interaction matrix may be determined based on the block generation information, block generation voting information, and indicator information of each block.

[0049] Step S112, determining contribution quantification information based on the node interaction matrix.

[0050] Among them, the node interaction matrix can be determined as contribution quantification information.

[0051] In some optional implementations, in the disclosed embodiments, the voting information of each block includes the number of votes obtained by the block, and the block information of the block includes the information of the first node and the information of the second node. The first node is used to represent the node that generates the block, and the second node is used to represent the node that voted for the consensus of the block. In one implementation, each node can correspond to one or more second nodes.

[0052] Accordingly, in the embodiment of the present disclosure, step S111 may include: determining element information corresponding to each element in the node interaction matrix according to the information of the first node, the information of the second node, the indicator information and the number of votes corresponding to each block.

[0053] The element information corresponding to the element may include the value of the element in the node interaction matrix.

[0054] In one embodiment, the information of the first node includes the serial number of the first node, and the information of the second node includes the serial number of the second node.

[0055] The element information corresponding to each element in the node interaction matrix can be determined in the following manner: for each block, the element corresponding to the block in the node interaction matrix is ​​determined based on the serial number of the first node and the serial number of the second node corresponding to the block; the element information corresponding to the element is determined based on the indicator information and / or the number of votes.

[0056] Each block may correspond to at least two elements in the node interaction matrix. Specifically, the elements corresponding to each block in the node interaction matrix include: in the node interaction matrix, the element corresponding to the sequence number of the second node as the row number and the sequence number of the first node as the column number, and the element corresponding to the sequence number of the first node as the row number and the sequence number of the second node as the column number.

[0057] For the element corresponding to the number of the second node as the row number and the number of the first node as the column number, the value of the element in the node interaction matrix can be added to the indicator information of the block to obtain the element information of the element, and the element information of the element is used to update the value of the element in the node interaction matrix; for the element corresponding to the number of the first node as the row number and the number of the second node as the column number, the value of the element is added to the quotient of the indicator information of the block divided by the number of votes to obtain the element information of the element, and the element information of the element is used to update the value of the element in the node interaction matrix;

[0058] Exemplarily, assume that the serial number of the first node corresponding to block i is n, and the serial number of the second node is m, that is, block i is generated by the first node, and the second node votes on the consensus of block i, where n, m and i are all integers greater than or equal to 0, and m and n are both less than or equal to N.

[0059] The elements corresponding to block i in the node interaction matrix include the elements in the mth row and nth column of the node interaction matrix, and the elements in the nth row and mth column. For the element in the mth row and nth column, the value of the element in the node interaction matrix plus the indicator information of block i (element information) is used as the value of the element in the node interaction matrix; for the element in the nth row and mth column, the value of the element in the node interaction matrix plus the indicator information of block i divided by the value of the number of votes (element information) is used as the value in the node interaction matrix.

[0060] In an optional implementation, in the embodiment of the present disclosure, step S120 may include: determining contribution information of each node according to the rank vector of the node interaction matrix.

[0061] The rank vector of the node interaction matrix can be solved and used as the contribution information of the node. Exemplarily, the rank vector of the node interaction matrix is ​​a 1×N matrix, and the value of each element in the matrix is ​​the contribution information of the node with the same sequence number as the element.

[0062] Figure 3 is a flow chart of step S130 provided by an exemplary embodiment of the present disclosure. In some optional implementations, such as Figure 3 As shown, step S130 in the embodiment of the present disclosure may include the following steps:

[0063] Step S131, sorting each node based on the contribution information of each node.

[0064] Among them, the nodes can be sorted in order from largest to smallest according to the contribution information.

[0065] Step S132, based on the ranking of each node, determine the weight information of each node.

[0066] The weight information of each node may be set in order of the node ranking from front to back, that is, the node with a higher ranking is assigned a larger weight information, and the sum of the weight information of each node may be set to 100%.

[0067] In an optional implementation, in this embodiment, the blockchain transaction includes at least one of the following: voting, profit distribution, block sorting, and reputation evaluation. The blockchain network can be a consortium chain network.

[0068] Among them, the weight information of each node in voting, revenue distribution, block sorting and reputation evaluation can be determined according to the contribution information of each node, that is, the greater the contribution information of the node, the higher the weight information in voting, revenue distribution, block sorting and reputation evaluation; the higher the weight information of the node in voting, revenue distribution, block sorting and reputation evaluation, the more votes the node obtains in voting, the higher the revenue allocated in revenue distribution, the higher the ranking in block sorting and the higher the reputation evaluated in reputation evaluation.

[0069] Figure 4 It is a schematic diagram of a blockchain network provided by an application example of the present disclosure. Figure 5 It is a schematic diagram of block information and node interaction matrix provided by an application example of the present disclosure.

[0070] In this application example, Figure 4 As shown, the blockchain network includes 4 nodes, namely n1, n2, n3 and n4, and the sequence numbers of the 4 nodes are 1, 2, 3 and 4 respectively. Figure 5 As shown, the blockchain corresponding to the blockchain network includes 8 blocks. From left to right, the 1st to 8th blocks are generated by nodes n1, n2, n3, n4, n1, n3, n4, and n1 respectively.

[0071] In this application example, the third block is taken as an example. The block generation node (first node) of the third block is n3, and the nodes that vote for it are n3, n1 and n4 (second nodes). That is, the block generation information of the third block includes: the serial number 3 of the block generation node n3 and the serial numbers 3, 1 and 4 of the voting nodes n3, n1 and n4 (second nodes).

[0072] A node interaction matrix of size 4×4 may be created, in which the initial value of each element is 0. The elements corresponding to the third block in the node interaction matrix include: the element in the third row and third column, the element in the first row and third column, the element in the fourth row and third column, the element in the third row and third column, the element in the third row and first column, and the element in the third row and fourth column. For each of the elements in the third row and third column, the element in the first row and third column, and the element in the fourth row and third column, the value of the element in the node interaction matrix plus the indicator information of the third block may be updated as the value of the element in the node interaction matrix; for the element in the third row and third column, the element in the first row and the element in the third row and fourth column, the value of the element in the node interaction matrix plus the quotient of the indicator information of the third block divided by the number of votes of the third block may be updated as the value of the element in the node interaction matrix. For each block, perform the operation of the third block, then solve the rank vector of the node interaction matrix, and determine the contribution information of each node through the rank vector. Among them, the element in the third row and the third column is calculated twice, and the final value (element information) of the element in the third row and the third column is the sum of the values ​​calculated twice, that is, the node information of the element is the value of the element in the node interaction matrix plus the value obtained by the indicator information of the third block, and the sum of the values ​​obtained by dividing the quotient of the indicator information of the third block by the number of votes of the third block.
