Initiative Scope and Goals

Galaxy Digital launched the Bitcoin Quantum Readiness Initiative on July 21, 2026, characterizing the quantum threat as a "real but manageable" long-term engineering challenge rather than an imminent existential crisis [Source: https://www.galaxy.com/newsroom]. The initiative commits $5 million in developer grants to fund post-quantum signature schemes and migration tools, positioning the risk as a solvable problem that the network has ample time to address [Source: https://www.theblock.co].
Initiative Scope and Goals
The initiative aims to bridge the gap between quantum computing advancements and Bitcoin's conservative development cycle through three primary pillars:
- Developer Grants ($5M): Funding for quantum-resistant transaction proposals (e.g., BIP-360), post-quantum signature schemes like ML-DSA, and wallet migration tooling [Source: https://bitcoinmagazine.com].
- Quantum Advisory Council: A panel of experts including Barry Sanders (University of Calgary) and Eran Tromer (Boston University) to provide technical guidance [Source: https://www.galaxy.com/newsroom].
- Research & Education: Analysis via Galaxy Research to clarify technical threats for institutional investors and policymakers [Source: https://finance.yahoo.com].
Technical Mechanism of the Threat
The primary threat stems from Shor’s algorithm, which, when run on a sufficiently powerful Cryptographically Relevant Quantum Computer (CRQC), could derive a private key from an exposed public key [Source: https://www.coinbase.com/research].
Bitcoin's vulnerability is concentrated in specific address types:
- Exposed Public Keys: Legacy "Pay-to-Public-Key" (P2PK) addresses and any address that has previously sent a transaction (thereby revealing its public key to the ledger) are vulnerable [Source: https://projecteleven.xyz].
- Hashed Addresses: Modern "Pay-to-Public-Key-Hash" (P2PKH) addresses remain secure until a transaction is initiated, as the public key is hidden behind a quantum-resistant hash until the moment of spending [Source: https://www.coinbase.com/research].
Risk Assessment and Timeline
Galaxy Research and independent analysts identify a significant portion of the Bitcoin supply as "at-risk" if users do not migrate to quantum-resistant standards before CRQCs emerge.
| Metric | Value / Detail | Source |
|---|---|---|
| At-Risk Supply | ~6.65M to 7M BTC (~35% of supply) | [Source: https://www.coindesk.com] |
| Estimated Value at Risk | ~$461B to $470B | [Source: https://www.coinbase.com/research] |
| CRQC Timeline | Expected 2030–2033 | [Source: https://projecteleven.xyz] |
| Regulatory Deadline | December 2031 (U.S. Federal PQC transition) | [Source: https://www.galaxy.com/newsroom] |
Is the Risk Existential?
Galaxy leadership, including CEO Mike Novogratz and Head of Research Alex Thorn, argues the risk is not existential because the network's open development model allows for the implementation of soft forks to introduce quantum-resistant signatures [Source: https://www.theblock.co].
Current progress includes:
- BIP-360: A proposal for quantum-resistant address types that eliminate public-key exposure [Source: https://bitcoinmagazine.com].
- NIST Standards: The initiative leverages 2024 NIST post-quantum standards, with firms like BTQ Technologies demonstrating quantum-safe Bitcoin implementations using ML-DSA as of late 2025 [Source: https://www.galaxy.com/newsroom].
Conclusion: While the threat to ~35% of the current BTC supply is technically valid, Galaxy Digital views it as a manageable engineering hurdle. The "existential" nature of the risk depends on the timely adoption of post-quantum upgrades (like BIP-360) before the projected 2030–2033 window for quantum breakthroughs.
