Problems solved by technology

[0003] The existing workload proof consensus mechanism (Proof of work, PoW) has a high degree of decentralization, but it takes about 10 minutes to generate a block, which is inefficient and cannot meet the data requirements of various applications
[0004] In addition, the consensus mechanism of Delegated Proof of Stake (DPoS) has higher block generation efficiency than PoW, and can generate a block in a few seconds; but the degree of centralization is low

Abstract

The invention relates to a DPoS consensus method and device, and the method comprises the steps: enabling a block chain node to determine a block node group from alternative block node groups througha workload proof mode, wherein the block chain node is any one alternative block outlet node in the alternative block outlet node group; enabling the blockchain node to receive a transaction request sent by a client, wherein the transaction request comprises an initiator address, a receiver address, a transaction amount, a client signature and a timestamp; the block chain node sends the transaction request to any one block outlet node in the block outlet node group; and enabling the block outlet node to receive the transaction, so that the block outlet node verifies and passes the transaction,the verified transaction is placed in a transaction pool, the block outlet node packages the transaction in the transaction pool into blocks in a DPoS consensus mode, and the blocks are linked. On the basis that the decentration degree of the block chain is not reduced, the block output efficiency of the block chain can be improved, and the method and device are suitable for various data chainingscenes.

Description

technical field [0001] This application relates to the field of block chain technology, especially to the DPoS consensus method and its device. Background technique [0002] The distributed consensus algorithm is an important technology to ensure the consistency of the system state in the distributed system, and it is an important basis for the distributed file system and the distributed database. The blockchain uses a distributed consensus algorithm to establish the system state in an environment where there is no central node control and there may be damage to the node, thereby establishing trust. [0003] The existing proof of work consensus mechanism (Proof of work, PoW) has a high degree of decentralization, but it takes about 10 minutes to generate a block, which is inefficient and cannot meet the data requirements of various applications. [0004] In addition, the consensus mechanism of Delegated Proof of Stake (DPoS) has higher block generation efficiency than PoW, ...
