Ravencoin 网络正面临一次少见的链上回滚处置。由于关键软件漏洞被利用,网络中出现无效区块,主要矿池正尝试从 8 月 7 日首个异常区块出现前重建链。这意味着过去数日内已完成的部分转账、充值和提现,可能不再被最终承认。

主要矿池重建替代链

链上数据显示,2Miners 和 RavenMiner 两家矿池正在从区块高度 4,487,775 开始重建链。这个区块是漏洞被利用前的最后一个正常区块,而首个异常区块出现在高度 4,487,776,对应时间为 8 月 7 日 15:44 UTC。

在工作量证明网络中,哪条链获得更多算力支持,哪条链通常就会被网络视为有效历史。如果更多矿工跟随这两家矿池,8 月 7 日以来写入链上的部分记录就可能被替换。

近四天交易面临撤销

对普通用户而言,最直接的影响是,周末期间看似已经完成的付款,之后可能从网络认可的历史中消失。Ravencoin 方面提醒交易所和服务商,不要假设被抹去的充值或提现会自动重新出现。

项目方称,部分处于回滚区间内的交易,可能会被重新打包进替代链,但这并不适用于所有记录。Ravencoin 同时建议,在网络最终只剩一个被广泛接受的版本前,交易平台暂停充值和提现操作。

  • 首个异常区块高度:4,487,776
  • 替代链重建起点:4,487,775
  • 风险时间范围:自 8 月 7 日以来的链上记录

交易所暂停 RVN 充提

交易平台已开始采取防范措施。Bitvavo 以漏洞被利用为由,暂停 RVN 充值和提现。韩国交易所 Upbit 则在韩元、比特币和 USDT 市场对 RVN 发出投资警示,并同步停止充值。

Ravencoin 表示,曾要求两家矿池从更靠后的区块高度开始重建,以减少需要回滚的历史范围,但矿池没有接受这一建议。这也显示出,在当前处置过程中,掌握主要算力的矿池对最终链历史有很大影响力,而维护软件的项目方并不能直接推翻矿池选择。

RVN 跌至约 0.0029 美元

受事件影响,RVN 在过去 24 小时下跌约 17%,报约 0.0029 美元,市值降至约 4800 万美元,成交额约 1000 万美元。过去一年,该代币累计跌幅约 77%。

补充信息:这并非 Ravencoin 首次遭遇严重协议问题。2020 年,攻击者曾利用另一处漏洞,铸造出约 3100 万枚超出规则限制的 RVN,随后相关问题才被修复。
