[ANN] Quantum Bitcoin (Q-BTC) | MAINNET LIVE | Post-Quantum PoW (ML-DSA-65)

[qbtc-core]

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:

UPDATE: May 22, 2026 (Bitcoin Pizza Day) - MAINNET IS LIVE & WHITEPAPER V2.0

Sixteen years ago today, classical Bitcoin established its first physical value boundary. Today, we establish its post-quantum survival boundary.

The theoretical blueprint phase is over. The Q-BTC Post-Quantum Mainnet is officially LIVE.

Over the past month, the architecture has been materialized from the ground up into a pure Rust physical implementation. The North American seed nodes (Dallas & Utah) are fully synchronized, and the network is actively hashing via the 128-bit fixed-point ASERTi3-2d continuous difficulty engine.

Core Deliverables Today:

• 100% Open Source Codebase Released: The complete Layer-1 consensus engine, featuring native ML-DSA-65 signatures, Actor-Driven UTXO rollbacks, and compact block routing, is now public.
  
• Official Whitepaper V2.0 Published: Deeply refined mathematical models, introducing the L1 Asymmetric Time-Lock Recovery Game and the ZK-STARKs stateless verification evolutionary roadmap.
  
• Genesis Bootstrapping Concluded: The initial 200-block physical bootstrapping phase is complete. This was executed strictly to calibrate the difficulty engine under live conditions and stress-test the RocksDB I/O against massive lattice signatures. The network has achieved operational equilibrium and is now completely open to global, decentralized PoW participation.
  

Official GitHub Repository (Source Code & Whitepaper V2.0):
https://github.com/Q-Jack-core/quantum-btc

There are no pre-compiled binaries for the masses yet, no VC allocations, no presales, and no complex tokenomics. Just pure, monolithic PoW consensus. True cypherpunks build for the protocol.

To participate: Clone the repository, compile from source (cargo build --release), and let your nodes sync.

Welcome to the quantum age, BoozyTalking.
The genesis block was just the ignition. The network is alive and the target is adjusting. May your hashes be fast.

Welcome! We are building this from the ground up, so it's just pure code right now—no fancy websites.
Mining currently requires running a full node and compiling the Rust code yourself. We'd love to have you onboard if you enjoy tinkering with new open-source protocols. Check the GitHub link in the main post to get started!

Code:

verify_recovery_reveal

is a stub, recovery claims are unverified.
In

Code:

utxo.rs

, the function that's supposed to validate a delayed-recovery claim against the committed

Code:

recovery_hash

does absolutely nothing:

Code:

fn verify_recovery_reveal(&self, tx: &Transaction, input_idx: usize, _target_hash: &[u8; 32]) -> bool {
    // "For the current version, existence of a valid witness for the heir is checked."
    tx.witnesses.get(input_idx).is_some()
}

The

Code:

_target_hash

parameter is ignored entirely. Any attacker who knows a UTXO has a

Code:

RecoveryInfo

field, and waits out the

Code:

activation_height

, can steal those coins by supplying any valid witness at all. The recovery hash commitment provides zero protection. This is a fund theft vector and a disqualifying bug for any mainnet use.
