Galaxy pledges $5M for developers quantum-proofing Bitcoin

COINTELEGRAPH ·

Galaxy Digital has pledged up to $5 million in grants to open-source developers building post-quantum cryptography for Bitcoin. The company also formed a quantum advisory council under its Bitcoin Quantum Readiness Initiative, which it announced Tuesday. The council includes Barry Sanders, professor and scientific director of Quantum City at the University of Calgary; Damien Bérubé, an MIT Sea Grant Knauss fellow; and Eran Tromer, professor of computer science at Boston University. The grants will fund quantum-resistant upgrade proposals, post-quantum cryptography, Bitcoin signature schemes, wallet and custodian migration tooling and formal security audits. Bitcoin’s quantum security is a growing concern, as about 30% of Bitcoin’s supply could be exposed if cryptographically relevant quantum computers emerge, according to analytics provider Glassnode. This includes 10% of the supply considered “structurally unsafe” because of its output type, and 20% considered “operationally unsafe” because of key or address management practices. The timeline for a practical quantum computing breakthrough remains hotly debated. In November 2025, Blockstream CEO Adam Back that Bitcoin faces no meaningful quantum threat for at least the next 20 to 40 years. Back said this gives the network ample time to adopt the post-quantum cryptography standards approved by the US Department of Commerce’s National Institute of Standards and Technology (NIST). In August 2024, NIST published three post-quantum cryptography standards for key establishment and digital signatures. The standards include key exchange, digital signature and hash-based signature algorithms that could underpin future post-quantum migrations across industries, including potential Bitcoin upgrades.

Wealth management company Bernstein said in an April report that Bitcoin has about three to five years to prepare for a post-quantum security upgrade.
