Abstract

The invention relates to a block chain random consensus method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a digital signature and a verifiable random number of each node; Verifying the acquired digital signature and verifiable random number of each node; When the verification is passed, generating an outblock node sequence proposal corresponding to the current node according to the acquired verifiable random number, and synchronizing the outblock node sequence proposal corresponding to each node; Determining a block node sequence according to the node weight value and the block node sequence proposal corresponding to each node; Creating a data block by each node according to the determined outblock node sequence; And adding thecreated data block to the current block chain. According to the method, by verifying the verifiable random number of each node, a consensus is formed for the sequence of the block output nodes, the sequence of the block output nodes of the block chain system within a period of time is determined, communication among the nodes is reduced, and the creating efficiency of the block chain is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a block chain random consensus method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, blockchain technology has emerged. Blockchain technology (Blockchain technology, BT), also known as distributed ledger technology, is an Internet database technology, which is characterized by decentralization, openness and transparency, allowing everyone to participate in database records. The blockchain is a data storage system that is jointly maintained by multiple distributed nodes. Multiple data blocks are connected into a chained data structure, and the data is transmitted and synchronized through a consensus mechanism to ensure the consistency of the data of each node. Node data cannot be modified. In blockchain technology, the consensus mechanism is particularly important. [0003] However, in tradi...
