[Cryptography] Quantum Bitcoin (Q-BTC): A Post-Quantum PoW Electronic Cash System

[qbtc.core]

I have been researching the operational vulnerabilities of ECDSA against polynomial-time extraction via Shor's algorithm.

In existing networks, the 10-minute mempool propagation latency creates an exploitable window for quantum Replace-by-Fee (RBF) front-running. To close this attack surface at Layer 1, I have implemented a Proof-of-Work electronic cash system that natively integrates the NIST-standardized ML-DSA-65 directly into the consensus path.

To mitigate the inherent ~3.3 KB lattice signature bloat, the node software employs a PQ-SegWit structure, isolating witness data at the RocksDB storage level.

The genesis block has been mined, and the initial peer-to-peer network is now operational. The difficulty is continuously adjusted via a 128-bit ASERTi3-2d algorithm.

I would appreciate any thoughts or critiques from this list regarding the lattice integration and the cryptographic implementation.
