Block chain complex transaction verification method and device based on game model

Abstract

The invention discloses a block chain complex transaction verification method and device based on a game model. The method comprises the following steps: electing verification nodes for processing a to-be-verified transaction to form a committee; carrying out deduction under the chain to obtain the verification difficulty and the final state of the to-be-verified transaction, determining a verification time limit and a deposit limit according to the verification difficulty, adding excitation, and broadcasting the information to a committee; enabling the committee to detect the transaction deposit capacity and the conflict situation, and initializing the voting container if the transaction deposit capacity and the conflict situation succeed and meet the complexity lower limit requirement; enabling the verifier in the container to independently complete verification within the verification period and commit and broadcast the verification result by adopting a cryptography commitment scheme; and after all the verification nodes complete the commitment of the verification result or the verification time is equal to the verification time limit, enabling the committee to clear the commitment verification result of the verification nodes, and carrying out rewards and punishment on the verification nodes according to the clearing result. According to the method, the correctness, universality, consistency, excitation compatibility and public verifiable capability of a verification result are ensured.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a game model-based method and device for verifying blockchain complex transactions. Background technique [0002] With the rapid development of information technology and the Internet, people are no longer satisfied with using a fragile and limited single node to handle various transactions, but building a highly robust distributed network to deploy multiple types of public services with rich functions . However, this process also introduces thorny trust and fairness issues. Blockchain technology stands out with its excellent anti-sybil algorithm and incentive mechanism: this technology screens out reliable nodes to lead the network through computing power proof to resist the invasion of malicious nodes. ;By rewarding valuable virtual tokens to attract node participation and incentivize honest behavior, as a whole, through the organization of an open decentr...

Problems solved by technology

This technology realizes the separation of mining and verification, and replaces the probabilistic consensus with strong consensus to provide a shorter transaction confirmation delay, but it still cannot support the verification of complex transactions. Rational nodes can copy the verification results of other nodes by listening to the channel. Skip validation, which can be exploited by malicious nodes to compromise the security of transaction validation
