摘 要：PoW(Proof of Work)plays a significant role in most blockchain systems to grant an accounting right over decentralized participants and ensure tamper *** hash functions are generally exploited for PoW due to their merits on summering,anti-collision,and irreversibility,they cannot certify that the bookkeeper is exactly the ***,such insistence may lead to abuse or even embezzlement of computing power for the benefit of malicious *** preserve the functionality of PoW but also bind the miners’signing keys with their works,we build a post-quantum PoW scheme by changing the approximate closest vector norm for probabilistic *** from the schemes based on hash functions,our scheme takes signing as the proof of work where signature verification is just the evidence of block *** also presented a method to adjust the difficulty of signing by modifying the probability of generating a correct *** performance of our scheme is also analyzed theoretically and experimentally,which implies its practicability and advantages.
