Feb 6 · 1 min read · Falcon 后量子签名在 Bitcoin Core 中的的集成和性能实测 Falcon 是一种基于格点（lattice-based）的后量子数字签名方案，特点是签名和公钥大小较小，签名和验证时间较短。 该代码（GitHub repo: bitcoin-falcon）演示了 Falcon-512 在 Bitcoin Core 中作为软分叉的集成和基准测试，并提供了与传统 ECDSA 方案的比较。比较结果显示出了 Falcon 之于当前选择的后量子签名算法（如 SPHINCS+ 和 ML-DSA）...

Jan 23 · 1 min read · Bitcoin Core：增量突变测试提升测试覆盖效率 Bruno Garcia 介绍了他在改进变异测试（mutation testing）方面的工作 。该技术通过向代码库中引入系统性缺陷（变异体 / mutants）来评估测试的有效性：测试失败则变异体“被杀死”，表明测试能够捕获该错误；测试通过则变异体“存活”，说明测试存在缺陷或覆盖不足。 这项工作的目的是提升增量突变测试的效率。Bruno Garcia 在八个公认测试中验证了他的方法并收集反馈，提出针对变异体的改进建议。 比特币的 BIP ...

Jan 9 · 2 min read · 利用盲式联署人建造比特币保险库 开发者 Jonathan T. Halseth 发布了一种使用盲化共同签名者的类保险库方案原型。与传统依赖共同签名者的方案不同，该方案采用了 MuSig2 的盲化版本，以确保签名者对其所参与签名的资金了解尽可能少。 为避免签名者在不明情况下对提交给他们的内容进行盲签，该方案在签名请求中附加了一个零知识证明，用于证明该交易符合预先设定的策略——在这个方案中，策略是一个时间锁。 Halseth 提供了一张展示该方案的流程图，其中包含四笔将被预签名的交易：初始存款交易、...
