开发者白帽解锁 2016年 ICO 合约百万美元资产
深潮 TechFlow 消息，6 月 01 日，据 The Block 报道，安全研究员 Florent 利用白帽漏洞成功解锁了 2016年 HongCoin ICO 合约中被锁定近十年的约 1,003枚 ETH（价值约 200 万美元）。该合约因旧版 Solidity 语言缺乏溢出保护，导致退款功能长期失效。Florent与 HongCoin 团队合作，通过管理员函数重置持仓余额完成解锁，整个过程历时约一周。目前 48 名原始投资者可申领解冻资金，已有两人共领取 96.5枚 ETH，并自愿向 Florent 支付白帽奖励。Florent 表示，此次解锁纯属技术探索，未收取任何费用或佣金。
