Optimism开发人员：在Optimism上创建ETH的漏洞已被修复:2月11日消息，以太坊二层扩容方案Optimism开发人员表示，一个严重错误已经在本月早些时候完成修复。根据Optimism博客文章中所述，该团队表示相关漏洞是在该项目以太坊客户端Geth分叉中发现的，具体而言，该漏洞可以通过在持有 ETH 余额的合约上反复触发SELFDESTRUCT操作码，导致在Optimism上创建ETH成为可能。该团队表示，根据其分析，除了以太坊数据初创公司Etherscan的一名工作人员意外激活外，该漏洞未被利用，在确认漏洞后几个小时候，Optimism就对该漏洞修复进行了测试并部署到Optimism的Kovan和Mainnet网络（包括所有基础设施提供商）。据悉，发现该漏洞的开发人员Jay Freeman获得了2,000,042美元赏金。[2022/2/11 9:44:31]
