Description
Technical Field
The present invention relates to the field of blockchain technologies, and in particular, to a distributed consensus system and method based on blockchains, a device, and a computer-readable storage medium.
Background
The block chain technology is a distributed account book technology, is jointly maintained by multiple parties, comprehensively uses the technologies of a distributed account book, a chain data structure, point-to-point transmission, a consensus mechanism, a cryptology principle and the like, has the important characteristics of decentralization, openness and transparency, no data falsification, traceability, privacy protection, high autonomy and the like, and is widely applied to multiple fields. In the blockchain network, transactions initiated by different participants must be sequentially written into an account book according to a generation sequence, and how to reach consistency of all nodes on the same transaction proposal in a distributed scene is an important problem that must be considered and solved by the blockchain technology. To achieve this goal, the transaction sequence must be correctly established, and a processing method for dealing with the tampered transaction or the maliciously submitted transaction must be included, and the consensus algorithm is a solution for ensuring the consistency of the distributed system, and the consensus algorithm is a process used in computer science for realizing the consistency of a single data value among distributed processes or systems, aiming at solving the reliability problem of a plurality of unreliable nodes in the distributed network.
The consensus algorithm is the basis for keeping block data consistent and accurate by nodes in the blockchain. In a block chain public chain, a workload certification consensus (POW) mechanism determines a billing weight based on computing power, determines the probability of obtaining the billing weight according to the percentage of the computing power in the total computing power, and a node needs to continuously consume computing power to perform hash calculation so as to find an expected random number. The credit evidence consensus mechanism (POS) determines the accounting right according to the number of held coins and the holding time, and determines the probability of obtaining the accounting right based on the percentage of the number of held coins and the holding time to the total amount of the system. The entrustment interest certification consensus mechanism (DPOS) is a consensus algorithm based on voting, similar to the agent democrasts, and is based on POS. In the block chain alliance chain, the consensus mechanism of Hyperledger Fabric is taken as a representative, and includes the consensus algorithms of Raft, kafka and the like. The consensus mechanism of HyperLegendr Fabric must satisfy both security and activity attributes to ensure consistency between nodes. Where security means that each node guarantees the same input sequence and produces the same output result at each node, the same state change will occur at each node when the node receives the same series of transactions, and the algorithm must be identical to the result of execution of a single node system.
However, the following problems are common to the common recognition mechanism in the current blockchain technology:
1) The resource consumption is serious, and especially the consumption of the PoW consensus algorithm on the power resource is very large;
2) The transaction confirmation time is too long, so that the use scene is severely limited;
3) The transaction processing frequency is low, and the blocking delay of a large number of transactions is easily caused. These problems are also important bottlenecks for restricting the development of block chain technology, and new consensus mechanisms (such as DAG, poA, etc.) are continuously proposed, but the problems that the consensus mechanism faces low efficiency and cannot cope with high concurrency situations in particular are still not fundamentally solved.
