The physical qubit threshold required to break secp256k1 is dropping faster than anticipated.However, mere algorithmic substitution is insufficient. In existing PoW networks, Shor's algorithm doesn't just threaten static addresses; it transforms the 10-minute mempool confirmation delay into a lethal attack surface for quantum front-running.
I have published the architectural blueprint for
Quantum Bitcoin (QBTC).
Core Implementations:- Consensus Layer: Full deprecation of ECDSA. L1 integration of NIST-certified ML-DSA (Module-Lattice-Based Digital Signature).
- Mempool Isolation: A base-layer Commit-Reveal scheme. Initiators broadcast a hashed intent (SHA256(PK || Tx_data || Salt)) first, revealing the ML-DSA signature only after block priority is secured.
- State Paradigm: 4MB PQ-SegWit architecture with an evolutionary roadmap towards ZK-STARKs state compression for polylogarithmic stateless verification.
- Genesis: A monolithic PoW architecture. Independent genesis block. Strict 21,000,000 supply cap. No cross-chain trust assumptions.
This is not a localized patch; it is an architectural reconstruction for the post-quantum epoch.
The whitepaper (PDF & Markdown with SHA-256 checksums) is officially open-sourced on GitHub:
