一种基于投票机制的黑名单公有链解决方案
A Public Chain Solution for Blacklist Based on Voting Mechanism
摘要
Abstract
Cryptocurrencies have become a financial tool used by many criminals in committing crimes.Currently,the research on preventing abnormal funds from circulating within the cryptocurrency system is not effective.Combining smart contract and editable blockchain technolo-gy,a blacklist public chain solution based on a voting mechanism is proposed.The solution first uses smart contract technology to design the voting process of whether to add a fund to the blacklist from a game theory perspective,setting measures of reward and punishment to encour-age participants to choose an honest strategy.Then,for confirmed abnormal funds,the UTXO anomaly degree field is designed,and different processing measures of backtracking or assigning anomaly degrees are used according to the stages of the abnormal funds,utilizing the features of editable blockchain.Experimental results show that the average probability of transactions with the highest anomaly degree being selected in the block packaging process is only 19.5%,and the average probability of transactions originally selected being selected after being assigned the highest anomaly degree decreases to 68.4%.Meanwhile,the probability of transactions with different levels of anomaly degrees being se-lected shows a stepwise decreasing trend.The blacklist public chain solution based on a voting mechanism solves the problem of unreasonable basis for adding records and weak execution in the previous blacklist solutions,effectively preventing the circulation of abnormal funds.关键词
