Hi HN,I’ve been working on a blockchain design that takes a different approach to the 51% attack problem. Instead of making attacks instantly expensive through hardware or capital (as in traditional systems), it makes them structurally slow to execute, which in turn makes them costly and difficult to sustain over time.The core idea is simple: (1) Each node/identity is limited to ~1 hash/sec in the Proof-of-Work process, regardless of hardware (2) Remove parallel mining advantages (no work is sharable) (3) Shift influence toward sustained persistent participation rather than raw hashpower (4) Make generating sybil identities (in bulk) slow, costly, and difficult.I’ve built a browser-based MVP demonstrating the capped PoW model (as a reference implementation): https://grahambell.io/mvp/Proof_of_Witness.htmlThere’s also a short demo here (Capped PoW) : https://youtu.be/i5gzzqFXXUk?si=y_Pv5ZDv9SGhRFjYWebsite: https://grahambell.io/Curious whether the approach sounds interesting, or immedia...
