Description
Technical Field
The invention relates to the technical field of block chains, in particular to a PBFT (basic block Fourier transform) improved consensus algorithm of a block chain.
Background
The block chain technology is a distributed account book technology and is based on the common integration of a P2P protocol, an asymmetric encryption algorithm, a consensus mechanism and a distributed storage technology; the block chain carries out transaction information transmission and point-to-point transmission among the nodes by means of a P2P protocol, the security and reliability of the transaction information in the transmission process are guaranteed by means of an asymmetric encryption algorithm, the consistency of block chain link point accounts and the stable generation of new blocks are guaranteed by means of a consensus mechanism, and the transaction information is stored by means of a distributed storage technology.
The consensus algorithm is a core algorithm of the blockchain consensus mechanism, and the blockchain consensus mechanism can also be said to be formed by the consensus algorithm, for example, the consensus algorithm commonly used by the public chain includes: workload certificates (POW), rights certificates (POS), and shares rights certificates (DPOS), etc., various algorithms have both their advantages and their disadvantages.
The PBFT consensus algorithm is a consensus algorithm for selecting the bookkeeper based on a union chain, and the flow of the PBFT consensus algorithm is as follows:
(1) and a master node is elected from the nodes of the whole network, and the new block is generated by the master node.
(2) Each node broadcasts the new transaction to the whole network, and the main node sorts and stores a plurality of transactions which are collected from the network and need to be placed in the new block into a list and broadcasts the list to the whole network.
(3) After each node receives the transaction list, performing transaction according to sequencing simulation; and after all transactions are executed, calculating the hash abstract of the new block based on the transaction result, and broadcasting the hash abstract to the whole network.
(4) If the digests received by one node from 2f (f is the tolerable number of malicious nodes) other nodes are the same as the digests received by the other nodes, a commit message is broadcasted to the whole network.
(5) If a node receives 2f +1 commit messages, it can formally submit new tiles and its transactions to the local tile chain and state database.
Each block of the PBFT consensus process is generated by a unique master node, so there is no possibility of forking; however, in the algorithm, too many network messages need to be transmitted in the two stages of steps 3 and 4, which will cause a large network overhead; therefore, the performance of the current PBFT consensus algorithm-based blockchain system is not high.
