币界网报道：LAYERZERO completed the largest witch hunt in history, using a strategy similar to the prisoner's dilemma to clean up witch accounts. The campaign lasted for several weeks and encouraged users to report potential witch accounts through a self-reporting program and bounty hunting. During the self-reporting phase, more than 338,000 addresses self-reported, while 3,550 reports were received during the bounty hunting phase. During the event, LAYERZERO also introduced a margin mechanism to improve the accuracy of reports. In the end, the event received a margin of more than 240 ETH, and it is estimated that only 6.67%-13.33% of the addresses will be eligible for airdrops.
