FIG. 1 is a flowchart of a block chain consensus method based on a share authorization certification mechanism in an embodiment of this application. As shown in FIG. 1, it includes the following steps:

Step S1: Collect node information: Collect the node information of the node, and broadcast the node information to other nodes in the blockchain network that communicate with its own node. The node information contains the node identifier.

Blockchain network is a system based on blockchain technology, also known as distributed ledger technology, is an Internet database technology. It is characterized by decentralization, openness and transparency, allowing each user to participate in maintaining database records. Blockchain network is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and so on. The blockchain network mainly includes a data layer, a smart contract layer, a consensus layer, etc. Among them, the data layer encapsulates basic data and basic algorithms such as low-level data blocks and related data encryption and time stamps, while the low-level data blocks are chained The structure is presented, that is, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a tamper-proof and unforgeable distributed ledger guaranteed by cryptography. Smart contracts are based on these credible, non-tamperable data and can automatically execute some pre-defined rules, terms or algorithms. The consensus layer encapsulates a consensus mechanism. The goal of the consensus mechanism is to enable all nodes to save consistent and effective blockchain data. Different consensus mechanisms are used on the blockchain, which will have different effects on the overall performance of the system while meeting consistency and effectiveness. This step uses a blockchain network based on the share authorization certification mechanism (DPOS consensus mechanism). Any node in the blockchain network must abide by the rules of the share authorization certification mechanism. In this blockchain network, all nodes vote for a certain number of representative nodes, and the representative nodes act on behalf of all nodes to generate blocks and Confirm blocks and maintain orderly operation of the system.

In one embodiment, in step S1, collecting node information of the node, as shown in FIG. 2, includes:

Step S101: Calculate the node resource value: collect the node resource information, which includes the network connection speed, CPU idle rate, and memory idle rate, and add the network connection speed, CPU idle rate, and memory idle rate to obtain the node resource value.

When collecting node resource information, you can monitor the node's network connection speed, CPU idle rate, and memory idle rate through the hook mechanism to obtain node resource information.

In step S102, the node contribution degree is calculated: the number of historical block generations of the node and the total number of block generations of the blockchain network are collected, and the historical block generation number is divided by the total number of block generations to obtain the node contribution degree.

The node contribution degree in this step refers to the proportion of the node in the previous generation of transaction blocks, and the more blocks generated by itself, the greater the node contribution.

All nodes in the blockchain network are preset with a block generation record table. The block generation record table records the node ID, block speed, block pass ID or block failure corresponding to each generated transaction block Logo. Find out the transaction blocks generated by the node identifier of this node from the block generation record table. After removing the transaction blocks of the block failure identification, calculate the number of other transaction blocks to obtain the historical number of block generation of the node. After removing the transaction blocks identified by the block failure identification, the total number of transaction blocks in the block record table is calculated to obtain the total number of blocks generated.

Step S103: Calculate the historical service index: collect the historical block generation speed of the node, calculate the historical average block generation speed, and the historical average block generation speed is the historical service index.

The historical service index in this step refers to the average speed of the blocks in the historical block of the node. Find out the transaction blocks generated by the node identifier of this node from the block generation record table, and after removing the block of the block failure identification, obtain the block generation speed corresponding to the deleted transaction block, and find all the block speeds After the sum, divided by the node's historical number of blocks, the result is the historical service indicator.

In step S104, node information is obtained: the node information includes a preset node identifier, a node resource value, a node contribution degree, and a historical service index.

In order to distinguish the identity of nodes in the blockchain network, after any node is registered in the blockchain network, it will be assigned a unique node identifier for proof of identity. The node information in this step includes not only the collected and processed indexes, but also the node identifier, which is used to distinguish the identity of each node in the subsequent voting.

This embodiment collects node resource values, node contributions, and historical service indicators before voting on all nodes using the share authorization certification mechanism to provide reference data for subsequent voting elections to ensure that the representative nodes that are subsequently voted can be in effect Maximized state.

In one embodiment, in step S1, the node information is broadcast to other nodes in the blockchain network that communicate with their own nodes, including:

Step S111, establishing a connection: establishing a connection with other nodes in the blockchain network through the transmission control protocol TCP protocol.

TCP (Transmission Control Control Protocol) is a connection-oriented, reliable, and transport layer communication protocol based on byte stream. When the node broadcasts, it uses the TCP protocol to perform three handshake. After establishing a connection with other nodes, it sends its own node information to other nodes. The connection establishment process is as follows:

The node first sends a request for a syn message with a flag bit. After receiving the request, the other node sends a syn and flag ack to confirm the connection request; after receiving the request, the node sends ack again to confirm the completion of the TCP connection between the node and other nodes.

Step S112: Broadcasting: Broadcast the node information to other nodes in the format of a hypertext transfer protocol HTTP request message.

HTTP (HyperTextTransferProtocol, Hypertext Transfer Protocol) is a stateless connection established on TCP. After establishing a TCP connection, other nodes receive the node information sent by the node, and the node information is sent in the format of an HTTP request message. The HTTP request message includes 4 parts, which are the request line, request header, blank line and request body. The request line includes the request method, request URL, and http protocol version, where the request method is GET, POST, HEAD, or PUT, etc., and the request header includes node information, character set, and so on.

In order to ensure the safe and stable transmission of the node information, before the broadcast, the node information can also be encrypted by the private key preset by the node and broadcast to other nodes.

In this step, a TCP connection is established, and the node information of the node is broadcast to other nodes in the format of an HTTP request message. This broadcast method is safe, stable, and fast, and is suitable for the broadcast of the blockchain network.

Step S2: Voting: After obtaining the node information broadcast by multiple nodes in the blockchain network, after voting with the share authorization certification mechanism, the node information will continue to be broadcast to other nodes in the blockchain network that communicate with their own nodes.

Any node in the blockchain network not only broadcasts the node information of its own node to other nodes, but also receives the node information broadcast by other nodes. In this step, before voting on the node, it is not necessary to receive the node information broadcast by all nodes, but After receiving the node resource information of a certain number of nodes, for example, after receiving the node resource information broadcast by 90% of the nodes in the blockchain network, according to the node information, voting is conducted through the voting rules defined by the share authorization certification mechanism.

In one embodiment, step S2, as shown in FIG. 3, includes:

Step S201, screening nodes: after obtaining the node information broadcast by multiple nodes in the blockchain network, performing weighted calculation on each node information to obtain weighting coefficient values, sorting the weighting coefficient values of multiple nodes from high to low, screening M nodes with the highest weighting coefficient values are generated.

The weighting calculation formula of the weighting coefficient value Z _i is as follows:

Z _i = A _i *a+B _i *b+C _i *c

Among them, A _i is the node resource value of the i-th node, B _i is the node contribution of the i-th node, C _i is the historical service index of the i-th node, and a, b, and c are coefficients.

In the weighted calculation formula of the weighting coefficient value Z _i , the coefficients a, b, and c are constants with a value range of 0-1, and a+b+c=1, which can take values of 0.2, 0.5, and 0.3, respectively. .

When filtering out the M nodes with the highest weighting coefficient value, if there are multiple nodes with the same weighting coefficient value, for example, the selected nodes o, p, and q are the M-1, M, and M+1, respectively If the nodes have the same weighting coefficient value, then the node that has received the broadcast among the multiple nodes is selected.

Step S202, automatic voting: automatically vote for M nodes through the share authorization certification mechanism. After the voting is completed, the node information of multiple nodes is continuously broadcast to other nodes in the blockchain network that communicate with their own nodes.

The share authorization certification mechanism is encapsulated in the consensus layer of the blockchain network. Any node in the blockchain network follows the consensus mechanism of the consensus layer. In this step, any node follows the share authorization certification mechanism. Any node All use the same consensus algorithm to automatically vote on the M nodes selected at the consensus layer.

In this embodiment, the weighting coefficient values are calculated for the node information of multiple nodes, and the weighting coefficient values are sorted from high to low, and M nodes with maximum efficiency are selected. As voting nodes, automatic voting is completed through the share authorization certification mechanism. After the voting is completed, the node information of multiple nodes will continue to be broadcast. This point-to-point, one-by-one broadcast method to neighboring points, the propagation speed between nodes is fast, and the security of data transmission is higher. You can also share some hardware and software resources and services without going through intermediate entities, achieving the purpose of decentralization.

In one embodiment, in step S201, after obtaining node information broadcast by multiple nodes in the blockchain network, weighting calculation is performed on each node information to obtain weighting coefficient values, including:

Step S20101: Remove the nodes that have failed in the history of block generation: after obtaining the node information broadcast by multiple nodes in the blockchain network, find out whether there are multiple records of historical block failure records in multiple nodes in the preset block record table. If the node has a history of block failure records, the node is deleted.

If any node fails to generate blocks due to problems such as the failure of the network or consistency verification within a specified time, the representative node election will be directly eliminated.

In this step, the preset block generation record table is searched to find the corresponding node identifiers of the obtained multiple nodes. Is there a block failure identification in the block generation record table? If it exists, it is considered that the node corresponding to the block failure identification exists History record of block failure.

Step S20102: Calculate the weighting coefficient value: perform weighted calculation on the node information of multiple nodes after excluding the historical block failure records to obtain the weighting coefficient value.

Because the nodes of the historical block failure records do not need to calculate the weighting coefficient values, before calculating the weighting coefficient values, the nodes of the historical block failure records are removed to reduce the calculation power.

In this embodiment, for the nodes that have failed to generate blocks in history, the election of representative nodes is directly eliminated, which ensures the fairness of the voting election and improves the quality of subsequent representative nodes.

Step S3, generate representative nodes: arrange the votes of all nodes from high to low, obtain the top N nodes with the highest number of votes, define the N nodes as representative nodes, and update the node IDs corresponding to the representative nodes to the rotation accounting table , Broadcast the billing table in turns to all nodes in the blockchain network.

A consensus algorithm for screening representative nodes is preset in the consensus layer of the blockchain network. This consensus algorithm is the same as the rules for screening representative nodes defined by the share authorization certification mechanism in the prior art, for example:

dlist_i = get N delegates sort by votes

The above code is to automatically obtain the voting results of all nodes in the blockchain network, and automatically define the top N nodes with the highest number of votes as representative nodes. The value of N in the consensus algorithm can be preset and can be set proportionally, such as 10%. For example, when there are 1000 nodes in the blockchain network, 100 representative nodes are selected. It can also be set according to the coefficient, such as N=101, and 101 representative nodes are selected through this step. N nodes are selected as representative nodes, and the representative nodes have the right to take turns accounting according to the turn-by-turn accounting table, and the accounting process is the process of generating transaction blocks.

After filtering out N representative nodes, the node identifiers corresponding to the N representative nodes are also written into a preset rotation accounting table. In order to facilitate subsequent consistency verification through the rotation accounting table. In order to ensure the safety and reliability of the consistency verification, after all the node IDs of the N representative nodes are written into the rotation accounting table, the N node IDs in the rotation accounting table are also randomly sorted:

dlist_i=shuffle(dlist_i)

After the above random ordering, the final rotation accounting table is obtained, and the rotation accounting table is broadcast to all nodes in the blockchain network, so that the nodes can be used for subsequent consistency verification of the transaction block.

Step S4, block generation and verification: obtain transaction information, generate transaction blocks for the transaction information, broadcast the transaction blocks to other nodes in the blockchain network; receive transaction blocks broadcast by other nodes, and agree on the transaction blocks Verification, when the verification is passed, the transaction block will be signed and broadcast to other nodes in the blockchain network, the transaction block will be stored, and the node identification, block generation speed and block passing identification corresponding to the transaction block will be stored It is recorded in the block generation record table, otherwise the node identification and block failure identification corresponding to the transaction block are recorded in the block generation record table.

When any representative node that obtains the right to take turns accounting automatically receives the transaction information, the transaction information is generated into a transaction block, and the transaction block is also broadcast. The representative node not only completes the transaction block work, but also performs the consistency verification work. Among them, the consistency verification of the transaction block includes:

When the received transaction block has been signed by N nodes, it is automatically defined as verified; otherwise, the block header information in the transaction block is obtained, and the block header information contains the node identifier, and the node identifier and the rotation accounting table The order of the representative nodes is compared to determine whether it is the turn of the representative node corresponding to the current node ID to generate a block. If it is, it is determined that the verification is passed; otherwise, it is determined that the verification fails.

The consistency verification in this step is that the node checks whether the block header information of each block produced is consistent with the order of the rotation accounting table to ensure consistency. When the two are consistent, the private key preset area of the own node is used. The block header is signed to prove that the transaction block is verified. If the block verification is inconsistent, the node does not sign the transaction block. When the transaction block cannot satisfy the verification of M nodes, the next representative node automatically obtains the transaction information and regenerates the block.

This embodiment is based on the blockchain consensus method of the share authorization certification mechanism. By collecting the node information of all nodes in the blockchain network, when voting for the nodes, the node information is used as important voting data, combined with the DPOS consensus mechanism, the election A certain number of representative nodes are used as subsequent block generation and verification nodes. Using node information as important voting data, the elected representative nodes can all be in a state of maximum efficiency, ensuring the fairness of each node. Combined with the DPOS consensus mechanism, it guarantees node security and prevents the blockchain network from being maliciously attacked.
