Ask HN: 每秒 1 哈希算力的 PoW 机制，让 51% 攻击成为不可能——寻找工程师
1 分•作者: HurairahShamsi•5 个月前
我一直在研究一种新的工作量证明（PoW）架构，该架构围绕确定性挖矿节奏（我称之为“受限 PoW”）构建。<p>核心思想是一种协议强制的节奏模型，其中每个被允许的身份都以固定的速率（目前建模为 1 次哈希/秒）推进挖矿过程。节点不是通过原始算力竞争，而是通过确定性的方式推进挖矿过程。<p>更广泛的架构旨在通过持续的基础设施参与（正常运行时间、活跃的网络连接和身份准入限制）使横向扩展在运营和经济上变得昂贵，从而抵消大规模并行挖矿的优势。<p>在这种模型下，安全假设也会发生变化。由于挖矿进度是按被允许的身份来控制的，并且创世身份将被广泛分布，因此获得多数控制权的概率将渐近地趋向于 51%。在有限的时间内，实现传统的 51% 攻击实际上变得不可行。<p>为了验证核心机制，我构建了一个基于浏览器的 MVP，它演示了确定性的 1 次哈希/秒的节奏模型。MVP：https://grahambell.io/mvp/Proof_of_Witness.html 您也可以观看演示视频：https://youtu.be/i5gzzqFXXUk?si=y_Pv5ZDv9SGhRFjY<p>我目前正在寻找对分布式系统、共识机制或协议架构感兴趣的工程师，他们可能希望一起进一步探索构建这个项目。<p>如果该模型成立，下一阶段将是组建一个小型核心团队来完全构建该协议。早期的贡献者将有机会从头开始塑造系统的架构和方向。<p>如果您对这个愿景感兴趣，并且喜欢解决困难的分布式系统问题，请通过电子邮件 hurairah@grahambell.io 联系我，并附上：（1）您构建的一些东西（2）为什么这个问题对您很重要（3）您解决的一个困难的技术问题以及您是如何解决的<p>注意：这还不是一个经过润色的创业推介。我是一个单独的创始人，正在探索一种协议架构，该架构试图解决区块链系统中的中心化压力，我正在寻找认为这个问题值得研究的认真建设者。

I’ve been working on a new Proof-of-Work architecture built around deterministic mining pacing (what I call Capped PoW).<p>The core idea is a protocol-enforced pacing model where each admitted identity progresses through the mining process at a fixed rate (currently modeled as 1 hash/sec). Instead of competing through raw hashpower, nodes advance deterministically through the mining process.<p>The broader architecture aims to neutralize large-scale parallel mining advantages by making horizontal scaling operationally and economically expensive through sustained infrastructure participation (uptime, active network connections, and identity admission constraints).<p>Under this model the security assumptions change as well. Because mining progression is paced per admitted identity and genesis identities would be widely distributed, the probability of acquiring majority control trends asymptotically toward 51%. In finite time, achieving a traditional 51% takeover becomes practically infeasible.<p>To validate the core mechanism, I built a browser-based MVP that demonstrates the deterministic 1 hash/sec pacing model. MVP: https://grahambell.io/mvp/Proof_of_Witness.html You can also watch the Demo video: https://youtu.be/i5gzzqFXXUk?si=y_Pv5ZDv9SGhRFjY<p>I’m currently looking to connect with engineers interested in distributed systems, consensus mechanisms, or protocol architecture who might want to explore building this further together.<p>If the model holds up, the next phase would be forming a small core team to build the protocol fully. Early contributors would have the opportunity to shape the architecture and direction of the system from the ground up.<p>If you’re interested in the vision and enjoy working on hard distributed systems problems, email me at hurairah@grahambell.io with: (1) something you’ve built (2) why this problem matters to you (3) a difficult technical problem you worked on and how you solved it<p>Note: this isn’t a polished startup pitch yet. I’m a solo founder exploring a protocol architecture that attempts to address centralization pressures in blockchain systems, and I’m looking for serious builders who find the problem worth working on.
