Embodiment Construction

[0018] Before describing the specific implementation, in order to express the discussed content more clearly, the concept of the characteristics of the finite state automaton involved in the present invention is firstly explained. All transactions in the P2P financial industry can be called deterministic finite state automata (DFSM), and the transaction state machine M is defined as a five-tuple M=(Q,Σ,δ,q0,F), Q={(q0 ,q1,q2,…,qm)}, Q is the set of all states of the transaction state machine; Σ is the set of input events; δ is the set of transition functions δ:Q×Σ→Q; q0 is the initial state value q0∈Q , F is the set of terminal states For the same deterministic finite state automaton, when q0 is the same and the set of Σ input events is the same, the resulting terminal state Fi is also the same, where Fi∈F.

Abstract

The invention provides a P2P finance based blockchain mechanism and consensus algorithm. The method includes the following steps: 1. a step of preparation: selecting a leader and the leader computing a block if the leader receives sufficient transactions; 2. a step of computing the block: and eventually broadcasting the computed block; 3. a step of verifying the consistency between a state root of the block and the head part of the block; 4. a step of storing the block and the transactions; and 5. a step of completing the aforementioned steps: restarting the next turn of computing. The consensus algorithm increases credibility and transaction throughput, and effectively mitigates insufficient speed of transactions of the current block chain.

Description

technical field [0001] The invention relates to a blockchain technology, in particular to a consensus algorithm based on a P2P financial blockchain mechanism. Background technique [0002] In recent years, P2P finance has developed rapidly, but there are also some problems in the development process. The company's credibility is not enough, and customers do not trust the projects brought by the company. This is also a big obstacle in the development of P2P finance. However, the advent of blockchain technology has brought good news to the P2P financial field. Blockchain technology establishes a decentralized consensus mechanism, which combines digital encryption and game theory, so that participants do not need any external In the case of mandatory constraints, a trusted environment of mutual restraint is formed. This trusted environment removes the necessity of centralized authorization and external control, but is precisely based on mutual distrust. Therefore, in this dece...
