[0032] Figure 1 is a flowchart of a node processing method based on a blockchain provided by an example embodiment of the present disclosure. The present embodiment can be applied to a blockchain network, as shown in Figure 1 The method includes the following steps:

[0033] In step S100, block information of a blockchain corresponding to the blockchain network is obtained.

[0034] The blockchain network can include a plurality of nodes (Node), any node can be a computing device in the blockchain network, etc. The computing device can include, for example, a notebook computer, a desktop computer, a mobile phone, a server, etc. In an embodiment, the node in the blockchain network can be a consensus node, which can be used to generate blocks (block generation) and perform consensus voting on blocks, etc.

[0035] The block information includes block generation information, block generation voting information, and index information of each block in the block chain. Each block in the block information is a block that passes consensus. The block generation information of each block can be used to represent information in the process of generating the block and chaining the block. The voting information of each block is used to represent information of the block being voted by consensus in the chaining process. The index information of each block is used to represent information included in the block. In an embodiment, the index information of each block includes at least one of the number of transactions, the sum of transaction fees (Gas), and the number of accounts in the block.

[0036] In step S110, based on the block generation information, the block generation voting information, and the index information of each block, the contribution quantification information corresponding to the plurality of nodes is determined.

[0037] The contribution quantification information is used to represent quantified data of the plurality of nodes contributing to the block chain network. The quantified data of the contribution of each node can be a value corresponding to the positivity of the on-chain behavior of the node in the block chain network.

[0038] In an embodiment, the contribution quantification information can include the quantified data of each node. The quantified data of the contribution of the node can be determined by the index information of the block generated by the node, the number of generated blocks, and the voting on the block, etc. For example, based on the block generation information, the block generation voting information, and the index information of each block, the number of blocks generated by each node, the number of votes on the block, and the number of transactions in the generated block can be determined, and then the sum of the number of blocks generated by the node, the number of votes on the block, and the number of transactions in the generated block is determined as the quantified data of the contribution of the node.

[0039] In step S120, based on the contribution quantification information, the contribution information of each node in the plurality of nodes to the block chain network is determined.

[0040] The contribution information of the node is used to represent the degree of positivity of the on-chain behavior of the node in the block chain network. The on-chain behavior may, for example, include at least one of the following: generating a block (block generation), voting on a block consensus, processing a transaction, etc. The contribution information of the node is proportional to the degree of positivity of the on-chain behavior of the node. For example, the contribution information of each node can include a contribution value of the node to the block chain network; the higher the contribution value of the node, the higher the positivity of the on-chain behavior of the node in the block chain network. For example, the higher the contribution value of the node, the more blocks generated by the node, the more consensus voting on the block, and / or the higher the index information in the generated block, etc.

[0041] For example, the quantified data of the contribution of each node in the contribution quantification information can be determined as the contribution information of the node.

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

[0043] The blockchain transaction can be used to represent a related transaction corresponding to the blockchain network. For example, the blockchain transaction can include a revenue distribution of the revenue generated by the blockchain, for example, a preset contribution information and weight information corresponding relationship is established, in which the contribution information is proportional to the revenue information, that is, the higher the weight information corresponding to the higher revenue information. The weight information of each node can be determined according to the preset contribution information and weight information corresponding relationship and the contribution information of each node. In this example, the blockchain transaction is taken as an example of revenue distribution. When the weight information of the node is higher, the node can be allocated to a higher revenue.

[0044] In the embodiments of the present disclosure, by converting the block information, block voting information and index information of each block into contribution quantitative information, and determining the contribution information of each node through the quantitative information, the contribution information of each node in the blockchain network can be determined by comprehensively considering the block voting information and block information of each node, and the index information of the generated block. Thus, the quantification of the node contribution information is realized, and the contribution information is more accurate and objective.

[0045] Figure 2 is a flowchart of step S110 provided by an exemplary embodiment of the present disclosure. In some optional embodiments, as shown in Figure 2 Step S110 in the embodiments of the present disclosure can include the following steps:

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

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

[0048] In one embodiment, the value corresponding to each element in the node interaction matrix can be determined according to the block information, block voting information and index information of each block.

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

[0050] The node interaction matrix can be determined as the contribution quantitative information.

[0051] In some optional embodiments, in the embodiments of the present disclosure, the voting information of each block includes the number of votes obtained by the block, and the block information of the block includes information of a first node and information of a second node, the first node being used to represent a node that generates the block, and the second node being used to represent a node that votes for consensus of the block. In one embodiment, each node can correspond to one or more second nodes.

[0052] Correspondingly, in the embodiments of the present disclosure, step S111 can include: determining the 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 index information and the number of votes corresponding to each block.

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

[0054] In one embodiment, the information of the first node includes a serial number of the first node, and the information of the second node includes a 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, determining the element corresponding to the block in the node interaction matrix based on the serial number of the first node and the serial number of the second node corresponding to the block; and determining the element information corresponding to the element according to the index information and / or the number of votes.

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

[0057] For the element corresponding to the serial number of the second node as the row number and the serial number of the first node as the column number, the value of the element in the node interaction matrix is added to the index information of the block to obtain the element information of the element, and the value of the element in the node interaction matrix is updated with the element information of the element; for the element corresponding to the serial number of the first node as the row number and the serial number of the second node as the column number, the value of the element is added to the quotient value of the index information of the block divided by the number of votes to obtain the element information of the element, and the value of the element in the node interaction matrix is updated with the element information of the element;

[0058] For example, it is assumed 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 for consensus of block i, where n, m and i are integers greater than or equal to 0, and m and n are less than or equal to N.

[0059] The element corresponding to the zone block i in the node interaction matrix includes an element in the mth row and the nth column of the node interaction matrix, and an element in the nth row and the mth column of the node interaction matrix. For the element in the mth row and the nth column, a value obtained by adding a value of the element in the node interaction matrix to a value (element information) of the index information of the zone block i is taken as the value of the element in the node interaction matrix; for the element in the nth row and the mth column, a value obtained by adding a value of the element in the node interaction matrix to a value (element information) of the index information of the zone block i divided by the number of votes is taken as the value in the node interaction matrix.

[0060] In an optional implementation, in the embodiment of the present disclosure, the step S120 can include: determining the 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 the rank vector is taken as the contribution information of the node. For example, 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 FIG. 1 is a flowchart of the step S130 provided by an exemplary embodiment of the present disclosure. In some optional implementations, as shown in FIG. 1, the step S130 in the embodiment of the present disclosure can include the following steps: Figure 3

[0063] The step S131 sorts each node based on the contribution information of each node.

[0064] The nodes can be sorted in descending order of the contribution information.

[0065] The step S132 determines the weight information of each node based on the sorting of each node.

[0066] The weight information of each node can be set in the order from front to back according to the sorting of the nodes, that is, the node sorted in the front is allocated with larger weight information, and the sum of the weight information of all the nodes can be set to 100%.

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

[0068] ​The weight information of each node in voting, income 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 of the node in voting, income distribution, block sorting and reputation evaluation, and when the weight information of the node in voting, income distribution, block sorting and reputation evaluation is higher, the node obtains more votes in voting, is allocated higher income in income distribution, is sorted earlier in block sorting, and is evaluated higher reputation in reputation evaluation.

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

[0070] In the present application example, as shown in Figure 4 , the block chain network includes four nodes, n1, n2, n3 and n4, and the serial numbers of the four nodes are 1, 2, 3 and 4 respectively. As shown in Figure 5 , the block chain corresponding to the block chain network includes eight blocks, and the first to eighth blocks are generated by nodes n1, n2, n3, n4, n1, n3, n4 and n1 in order from left to right.

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

[0072] A 4*4 node interaction matrix can be created, and the initial value of each element in the node interaction matrix is 0. The elements corresponding to the third block in the node interaction matrix include the element in the third row and the third column, the element in the first row and the third column, the element in the fourth row and the third column, the element in the third row and the third column, the element in the third row and the first column, and the element in the third row and the fourth column. For each of the element in the third row and the third column, the element in the first row and the third column, and the element in the fourth row and the third column, the value of the element in the node interaction matrix is updated to the value obtained by adding the index information of the third block to the value of the element in the node interaction matrix. For the element in the third row and the third column, the element in the third row and the first column, and the element in the third row and the fourth column, the value of the element in the node interaction matrix is updated to the value obtained by adding the index information of the third block to the quotient of the index information of the third block divided by the number of votes of the third block. The operation on the third block is performed on each block, and then the rank vector of the node interaction matrix is solved, and the contribution information of each node is determined 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 of the two calculations, that is, the node information of the element is the sum of the value obtained by adding the index information of the third block to the value of the element in the node interaction matrix and the value obtained by dividing the index information of the third block by the number of votes of the third block.
