Ravencoin suffers from a consensus vulnerability; major mining pools support alternative chains, and the network faces a risk of deep reorganization in about three days. RVN once fell by over 20%.

Ravencoin 网络披露,共识层漏洞已被利用,部分无效区块自 8 月 7 日起被节点接受。随着主要矿池转向不包含受攻击分支的新链,网络可能出现约三天的深度重组,8 月 7 日之后的部分交易面临被撤销风险。

首个无效区块出现在 8 月 7 日

项目在 X 发布网络通知称,已确认首个已知无效区块出现在区块高度 4,487,776,时间为 2026 年 8 月 7 日 15:44:01 UTC。问题在于,存在漏洞的节点会接受本不应被确认的区块。

Ravencoin 采用工作量证明机制,与比特币类似。按这一规则,获得最多算力支持的链会被网络视为有效主链。因此,这次事件的后续走向,取决于矿池和矿工最终把算力投向哪一条链。

两大矿池支持替代链

通知显示,2Miners 和 RavenMiner 目前控制 Ravencoin 网络的大部分算力,并已宣布挖掘一条不包含被利用分支的链,起点为区块高度 4,487,776 之后。

如果更多矿工跟随这两家矿池,替代链就可能成为新的主链。届时,Ravencoin 网络将出现约三天的深度链重组,过去几天已确认的部分交易记录可能被抹去。

  • 最后一个被视为有效的区块:4,487,775
  • 可能被重组的起始区块:4,487,776
  • 潜在回滚时间跨度:约三天

交易所与用户面临撤销风险

项目方提醒,区块 4,487,775 之后确认的交易都应被视为存在风险。部分受影响交易可能会重新回到内存池,并再次被打包,但这并不保证一定发生。

项目方还特别提示,交易所不应假设被回滚的充值或提现会自动重新出现,或再次获得确认。这意味着,8 月 7 日以来的转账、支付、充值和提现,都可能因主链切换而失效。

开发者称,曾要求矿池考虑采用更靠后的恢复点,以减少对用户、服务商和交易所的影响,但这一请求未获接受。

公告扩散后币价急跌

消息传播后,RVN 迅速走低。报道援引市场数据称,RVN/USDT 当日一度下跌 20.40%,此前自 6 月中旬以来维持的区间走势被打破。

按文中数据,RVN 当前市值约为 4600 万美元,过去数小时内蒸发数千万美元。若从 5 月下旬约 0.0055 美元附近计算,RVN 已较当时高位回落接近一半。
