Galaxy Digital launched a Bitcoin Quantum Readiness Initiative today, committing up to $5 million in developer grants to protect the network against quantum computers. The program addresses a gap between rapid quantum computing advancement and Bitcoin's early-stage engagement with post-quantum cryptography, according to Alex Thorn, head of firmwide research at Galaxy. Bitcoin's security relies on elliptic curve cryptography, which a quantum computer running Shor's algorithm could break by deriving private keys from exposed public keys, enabling attackers to forge signatures and drain wallets.
Galaxy Structures Three-Pillar Quantum Defense Program
The initiative operates through three pillars. The grant program funds work on quantum-resistant transaction proposals, post-quantum signature scheme integration, wallet migration tooling, and security audits of proposed code. Galaxy will evaluate applications individually and disburse payments on a milestone basis, with applications accepted immediately at quantum@galaxy.com.
The second pillar consists of a research and publishing arm. Galaxy Research will publish analysis of the quantum threat and developer responses for investors, policymakers, and the technical community.
A Quantum Advisory Council forms the third pillar. The council guides research and evaluates grant proposals. Its initial members are 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, a professor of computer science at Boston University.
"As leaders in the digital assets space, we believe it's important that we help be part of the solution to any potential threat quantum computing poses to Bitcoin," said Mike Novogratz, founder and CEO of Galaxy. Sanders stated that quantum timelines "continue to compress" and that bitcoin should prepare alongside governments and industries.
Quantum Computers Threaten Bitcoin's Cryptographic Foundation
Bitcoin's security rests on elliptic curve cryptography. A machine running Shor's algorithm could break this scheme by deriving a private key from an exposed public key. An attacker with such a tool could forge a signature and drain a wallet, with nothing on-chain to flag the theft. No such computer exists today, yet the Bitcoin Policy Institute has warned that the estimated timeline for one keeps compressing, narrowing the window for network upgrades.
Old and reused addresses face the sharpest risk because their public keys sit exposed on the ledger. An estimated 1.7 million BTC rest in legacy pay-to-public-key addresses, a stash with keys on permanent display.
BIP-360 Proposal Advances Quantum-Resistant Transactions
Defenses under review center on migration to quantum-resistant address types and new signature schemes. BIP-360, a proposal from developer Hunter Beast, removes public-key exposure from standard transactions. The proposal merged into the Bitcoin Improvement Proposal repository this year. BTQ Technologies deployed a working implementation on a quantum testnet.
Bitcoin's decentralized governance turns such changes into a slow process of design, review, testing, and deployment that can span years. The pool of developers working on the problem remains small relative to its scale.
Federal Quantum Deadline Set for 2031
President Trump signed executive orders that advance U.S. quantum work and set a 2031 federal deadline for post-quantum defense. NIST finalized its first post-quantum standards in 2024.
Galaxy said it welcomes co-funders and other stakeholders, and acknowledged that peers may pledge their own funds toward the same goal. The firm cast that prospect as a benefit rather than a rivalry, with an open invitation to institutions and developers who want to join.
FAQ
What did Galaxy Digital launch today?
Galaxy Digital launched a Bitcoin Quantum Readiness Initiative today, committing up to $5 million in developer grants to protect the network against quantum computers. The program includes a grant program, a research and publishing arm, and a Quantum Advisory Council.
Why does Bitcoin face a quantum computing threat?
Bitcoin's security relies on elliptic curve cryptography, which a quantum computer running Shor's algorithm could break by deriving private keys from exposed public keys. An estimated 1.7 million BTC rest in legacy pay-to-public-key addresses with keys on permanent display, making them vulnerable to such attacks.
What is BIP-360 and when did it merge?
BIP-360 is a proposal from developer Hunter Beast that removes public-key exposure from standard Bitcoin transactions. The proposal merged into the Bitcoin Improvement Proposal repository this year, and BTQ Technologies deployed a working implementation on a quantum testnet.
