Security interaction method, excitation method and transaction system for manager-free blockchain transaction

Abstract

The invention discloses a security interaction method, an excitation method and a transaction system for administrator-free blockchain transaction. The quality of a blockchain-based transaction systemcan be improved from two aspects of security at the same time. Firstly, in a buyer registration stage, a homomorphic encryption algorithm is introduced, and batch efficient signature verification ina verification stage is realized on the premise of ensuring key security. And in addition, in the consensus achievement stage, the tasks are sorted by adopting a reputation-based incentive mechanism,so that the waiting time of high-reputation buyers is shortened, and the transaction speed is increased. Finally, in the reputation updating stage, the reputation values of all the nodes are quantitatively evaluated periodically, and the reliability of the transaction system is improved.

Description

technical field [0001] The present invention relates to a secure transaction system, in particular to a secure interaction method, an incentive method and a transaction system for blockchain transactions without a manager. Background technique [0002] The traditional centralized trading system has centralized power when solving smart service transactions, and there is a problem of abuse of power by the centralizers. However, the trading system that cancels the manager will cause malicious transactions and untimely transactions due to the lack of administrators, which will lead to The reliability and security of the trading system are threatened. How to design a distributed sub-center service transaction model, break through the key technologies under the distributed architecture to ensure the security and reliability of transactions. [0003] Blockchain refers to a series of innovative general-purpose technologies based on cryptography principles rather than central nodes....

Problems solved by technology

[0005] The existing incentive mechanisms mainly include reciprocity mechanism, e-money-based mechanism and reputation mechanism. Since the reciprocity mechanism requires the establishment of a long-term reciprocal relationship, the commonly used e-money-based mechanism requires a trusted center, which is not suitable for no-manager trading systems. , so the reputation mechanism is adopted; however, the existing unclear incentive methods are vulnerable to attack
