Bitcoin Quantum

What Bitcoin Quantum does

Bitcoin Quantum (BTQ) is a post-quantum proof-of-work cryptocurrency project developed by BTQ Technologies. It is implemented as a fork of Bitcoin Core that replaces ECDSA signatures with NIST-standardized CRYSTALS-Dilithium (ML-DSA, FIPS 204), a lattice-based signature scheme resistant to Shor's algorithm. The protocol preserves Bitcoin's core economic properties — 21 million supply cap, halving every 2,100,000 blocks, SHA-256 proof-of-work, UTXO model, and peer-to-peer architecture — while adapting operational parameters (1-minute block times, 8 MB blocks, 16x witness scale factor, BIP-360 Pay-to-Merkle-Root) to accommodate the substantially larger post-quantum signatures and public keys.

The product surface centers on BTQ Core (the reference daemon and CLI), a wallet supporting both ECDSA and Dilithium key types, a public block explorer, a SHA-256 mining pool, and a documentation portal. Notable technical components include a custom OP_CHECKSIGDILITHIUM opcode, automatic signature-type detection for backward compatibility, cryptographic agility to adopt future NIST PQC standards, and native dilithium-bech32 address formats. The MIT-licensed codebase is hosted at github.com/btq-ag/btq-core; the public testnet launched on February 23, 2026 and is producing blocks with visible mining activity.

The project follows a community-led, open-source go-to-market model targeting four segments: quantum-concerned cryptocurrency holders, SHA-256 miners (who can use existing ASIC hardware), blockchain developers building wallets and integrations, and exchanges/custodians preparing institutional infrastructure. Revenue mechanics mirror Bitcoin's — miners earn a 5 BTQ block subsidy (1/10th of Bitcoin's initial reward, reflecting 10x faster blocks) plus transaction fees — but no mainnet revenue exists yet. Distribution is entirely self-serve via GitHub binaries and a public mining pool; no enterprise sales motion is operational. The BTQ Foundation, established in October 2025, coordinates industry-wide post-quantum migration efforts, and mainnet launch is targeted for Q2 2026 following Q1 2026 enterprise pilots.

Revenue model

1. Block Subsidy: Each new block creates 5 BTQ as reward for miners. This is 1/10th of Bitcoin's initial 50 BTC reward, compensating for 10x more blocks at 1-minute intervals. Halves every 2,100,000 blocks (~4 years), maintaining identical emission curve to Bitcoin with 21 million total supply cap.
2. Transaction Fees: Miners earn transaction fees based on weight-based pricing. Dilithium transactions are larger but benefit from 16x witness discount. Fee market provides ongoing miner revenue as block subsidy decreases through halvings.

Core offering

Bitcoin Quantum is an open-source, quantum-resistant proof-of-work blockchain forked from Bitcoin Core. It replaces ECDSA signatures with NIST-standardized CRYSTALS-Dilithium (ML-DSA, FIPS 204) post-quantum cryptography while preserving Bitcoin's 21 million supply cap, SHA-256 mining, and UTXO model. The project delivers a complete protocol stack including node software (BTQ Core), wallets, a block explorer, and a mining pool.

Product overview

Bitcoin Quantum is a quantum-resistant blockchain protocol and cryptocurrency that replaces Bitcoin's vulnerable ECDSA signatures with NIST-standardized Dilithium (ML-DSA) cryptography. The product ecosystem centers on BTQ Core (the protocol software forked from Bitcoin Core), the BTQ Core Wallet (for Dilithium key management and quantum-safe transactions), and BTQ Explorer (for blockchain navigation). Supporting infrastructure includes the BTQ Mining Pool for SHA-256 mining with post-quantum transaction security, all built on the quantum-resistant BTQ cryptocurrency with its 21-million supply cap, 1-minute blocks, and 8MB block size.

Direct peers

• Quantum Resistant Ledger: QRL is the longest-running quantum-resistant blockchain, using XMSS hash-based signatures. It is the most directly comparable project to Bitcoin Quantum in terms of both mission (quantum-resistant cryptocurrency) and architecture (UTXO-style chain with PQC signatures).
• IOTA: IOTA is a distributed ledger that has implemented Winternitz one-time signatures for quantum resistance. It competes in the same quantum-resistant cryptocurrency category as BTQ, though using a DAG-based Tangle rather than a Bitcoin-style blockchain.
• Mochimo: Mochimo is a quantum-resistant cryptocurrency using WOTS+ (Winternitz one-time signatures) on a blockchain similar in structure to Bitcoin. It is a direct functional peer to BTQ as an alternative post-quantum store of value.

Broad incumbents

• Ethereum: Ethereum is the largest smart-contract platform actively researching and roadmapping post-quantum signature migration (via account abstraction and EIP proposals). It represents the most consequential incumbent that could eliminate the need for BTQ if it successfully upgrades.
• Bitcoin: Bitcoin is the parent chain Bitcoin Quantum forks from and the primary incumbent in the 'store of value' cryptocurrency category. BTQ's entire value proposition depends on Bitcoin's inability or unwillingness to adopt post-quantum cryptography, making Bitcoin both the inspiration and the primary competitive threat.
• Solana: Solana is a high-throughput Layer-1 blockchain actively researching post-quantum signature integration (including winternitz-style schemes). It competes for throughput-oriented use cases where BTQ's ~24 tx/sec positioning also plays.

Emerging players

• Cardano: Cardano (via IOG research) has published research on integrating FALCON and other post-quantum signature schemes into its extended UTXO model. It is an emerging competitor pursuing the same UTXO-plus-PQC architectural space as BTQ.
• Chia Network: Chia is an alternative proof-of-work blockchain (using space and time proofs rather than SHA-256) that competes for the same environmentally-conscious, store-of-value crypto positioning as BTQ. It is an emerging peer in the 'next-generation PoW' category.
• Algorand: Algorand has researched and prototyped FALCON post-quantum signature integration for its Layer-1 chain. It is an emerging peer pursuing stateful post-quantum signature migration on a UTXO-style architecture.

Others

• PQShield: PQShield is a post-quantum cryptography company providing PQC software and hardware IP. While not a competing cryptocurrency, it represents the broader PQC ecosystem in which BTQ operates and could be a partner or acquirer of PQC-related IP relevant to BTQ's roadmap.
