Ask HN: 1 Hash/Sec paced PoW making 51% attacks impossible – seeking engineers

1•HurairahShamsi•1h ago
I’ve been working on a new Proof-of-Work architecture built around deterministic mining pacing (what I call Capped PoW).

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.

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).

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.

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

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.

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.

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

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.
