ChainCatcher 消息，据 Decrypt 报道，Coinbase 量子咨询委员会发布报告，呼吁区块链开发者立即开始抗量子迁移准备工作，警告未解决的废弃和易受攻击代币问题可能成为比特币最大的挑战之一。
报告估计，约 700 万枚比特币因公钥暴露和地址重用而容易受到未来量子攻击。尽管目前尚无量子计算机能破解区块链加密，但最早在 2030 年出现相关量子计算机的可能性较大。
报告提出对未迁移至量子安全地址的代币的三种处理方案：设定截止日期后永久冻结或销毁；不做任何处理让用户自行决定；采取折中措施，如限制每区块可移动的易受攻击代币数量，或允许用户预先承诺迁移。
以太坊基金会已成立团队协调后量子安全过渡，Vitalik Buterin 于 2 月制定了量子升级路线图。Stellar 发展基金会周二公布了用户迁移至量子安全加密的路线图。
