Gate News 消息,4 月 10 日,StarkWare 研究员 Avihu Levy 发布题为《无需软分叉的量子安全比特币交易》的研究提案,提出一种名为 QSB 的量子安全比特币方案。该方案核心在于用基于哈希的安全假设替代椭圆曲线机制,将安全性建立在哈希原像抗性之上,以此抵御 Shor 算法对比特币的潜在威胁。QSB 方案的显著特点是在比特币现有脚本限制内运行,无需进行共识变更或软分叉即可实现量子安全。不过,QSB 交易超出了标准中继策略限制,无法通过默认网络设置传播,需借助 Slipstream 等服务直接提交给矿工。研究估算,使用云 GPU 生成一笔有效 QSB 交易的成本约为 75 至 150 美元。目前该方案的完整交易组装和广播功能尚未在链上进行实际演示。
