Embodiment 1

[0091] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0092] The present invention provides a Byzantine fault-tolerant consensus method applied to alliance chains, comprising the following steps:

[0093] S1: During each round of consensus, according to the private key stored on each consensus node to be selected, the serial number of each consensus node to be selected, the number of the current view and the area generated by the alliance chain in the previous round of consensus The hash value corresponding to the block is calculated to obtain the hash value corresponding to each candidate node;

[0094] The hash value corresponding to the block generated in the previous round of consensus process is the hash value corresponding to the consensus node in the previous round of consensus process.

[0095] Wherein, the S1 is specifically:

[0096] Calculate the hash value corresponding to each node to be selected by preset the first formula;

[0097] Th...

Abstract

The invention provides a Byzantine fault-tolerant consensus method and a terminal applied to a coalition chain. The method comprises the steps of in each round of consensus process, according to the private key, serial number, current view and the hash value corresponding to the block generated in the previous round of consensus process, calculating the hash value corresponding to each selected consensus node, thereby the unique first consensus node is selected; And generating proposal information through the first consensus node and sending the proposal information to each consensus node to be selected respectively; according to the verification passing information corresponding to the proposal information sent by the selected consensus node, generating the identification information andtransmitting the identification information to each selected consensus node respectively; and if the number of verification passing information corresponding to the identification information receivedby the first consensus node exceeds the preset number, executing the next round of consensus. By adopting the scheme, the invention not only improves the consensus performance of the alliance chain,but also ensures the safety of the alliance chain.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a Byzantine fault-tolerant consensus method and terminal applied to alliance chains. Background technique [0002] An important parameter of the VBFT consensus algorithm adopted by Ontology is the PoS (Proof of Stake, PoS) table of the consensus network nodes. During the operation of the VBFT algorithm (Verifiable Random Function Byzantine Fault Tolerance, verifiable random function Byzantine fault tolerance algorithm), all nodes randomly select nodes participating in each round of consensus according to the current consensus PoS table, and the randomly selected nodes complete the corresponding round of consensus Work. [0003] The VBFT algorithm can be considered as an improvement of the traditional BFT algorithm (Byzantine Fault Tolerance, Byzantine Fault Tolerance Algorithm) in the direction of verifiable randomness. In the VBFT algorithm, firstly, based on the verifiab...
