Galaxy Digital Commits Up to $5M to Harden Bitcoin Against Quantum Threat

Galaxy's grant program targets the developer gap on post-quantum Bitcoin upgrades before Q-Day timelines compress any further.

Key takeaways

• Galaxy Digital (Nasdaq: GLXY) launched the Bitcoin Quantum Readiness Initiative, committing up to $5 million in developer grants, research publishing, and a new Quantum Advisory Council, with applications open immediately via [email protected].
• The initiative backs the BIP-360 voluntary migration path, funding post-quantum signature scheme integration and wallet migration tooling rather than a coercive protocol overhaul.
• Quantum timelines are compressing: Project Eleven projects a cryptographically relevant machine by 2030-2033, and an estimated 1.7 million BTC already sit in legacy addresses with permanently exposed public keys.

Galaxy Digital, the Nasdaq-listed digital assets firm (GLXY), launched the Bitcoin Quantum Readiness Initiative on Tuesday, committing up to $5 million toward developer grants, a research publishing arm, and a new Quantum Advisory Council aimed at hardening Bitcoin against the arrival of cryptographically relevant quantum computers. First reported by Bitcoin Magazine, the announcement puts institutional capital directly behind the post-quantum upgrade process at a moment when the timeline to a threat keeps moving in the wrong direction.

The framing from Galaxy's own team cuts to it: "There's a gap between the quantum computing world, which is moving fast, and the Bitcoin development world, which is just beginning to engage with post-quantum cryptography in earnest," said Alex Thorn, head of firmwide research at Galaxy. That gap is the problem this program is designed to close.

Three Pillars, One Goal

The grant program is the first and most actionable pillar. Galaxy will fund work on quantum-resistant transaction proposals, post-quantum signature scheme integration, wallet and custodian migration tooling, and formal security audits of proposed code. Grants are judged individually and paid on a milestone basis. Applications open immediately through [email protected].

A research and publishing arm forms the second pillar, with Galaxy Research set to produce analysis of the quantum threat and the developer response for investors, policymakers, and the technical community.

The third pillar is the Quantum Advisory Council. Inaugural members: Barry Sanders, professor and scientific director of Quantum City at the University of Calgary; Damien Bérubé, MIT Sea Grant Knauss Fellow; and Eran Tromer, professor of computer science at Boston University. Sanders said quantum timelines are continuing to compress and that Bitcoin should be no exception to the preparation already underway across governments and industries.

"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.

Why the 1.7 Million BTC Number Matters

Bitcoin's security rests on elliptic curve cryptography. A machine running Shor's algorithm could derive a private key from an exposed public key, forge a signature, and drain a wallet with nothing on-chain to flag the theft. No such machine exists today. But the window is narrowing.

An estimated 1.7 million BTC sit in legacy pay-to-public-key (P2PK) addresses with public keys permanently on-chain. Those coins are the most exposed. A Bitcoiner holding in a modern SegWit or Taproot wallet faces a materially different risk profile than one sitting on a legacy address, and the practical action items are already available: avoid address reuse, don't hold in P2PK outputs. Galaxy's grants don't change those action items, but they fund the tooling that makes migration smoother for custodians and exchanges at scale.

The leading upgrade path is BIP-360 (Pay-to-Merkle-Root, P2MR), a proposal from Hunter Beast, Ethan Heilman, and Isabel Foxen Duke that removes public-key exposure from standard transactions by hiding keys behind a Merkle tree structure. It merged into the Bitcoin Improvement Proposal repository in February 2026, a documentation step, not an activated soft fork. Galaxy's grant program is explicitly oriented around this voluntary migration rail.

That distinction matters. The community split over BIP-361, Jameson Lopp's competing proposal that would enforce a migration timeline with potential invalidation of legacy signatures, remains live. Galaxy's money is flowing toward the non-coercive path. That is a meaningful signal about which approach institutional capital sees as compatible with Bitcoin's property-rights norms.

The Real Bottleneck Is Governance, Not Research

The broader context is active. NIST finalized its first post-quantum cryptographic standards in August 2024. The Trump administration signed Executive Order 14409, "Securing the Nation Against Advanced Cryptographic Attacks," setting a 2030 deadline for federal post-quantum key establishment and a 2031 deadline for post-quantum digital signatures. Project Eleven projects a cryptographically relevant quantum computer by 2030-2033. The pieces are assembling.

Here is the honest framing on the thesis: Galaxy's up to $5 million buys developer time and review capacity. It does not buy a consensus mechanism or a faster soft fork activation. Bitcoin's decentralized governance has no corporate sponsor that can force a timeline. The actual bottleneck, node operator and miner signaling for any BIP-360-class upgrade, is untouched by this grant program. If the grants produce funded developers shipping reviewed code and working wallet migration tooling within 18 months, the initiative justifies itself. If the $5 million concentrates in advisory council stipends and research PDFs with no shipped implementations and no soft fork activation progress, it doesn't.

Galaxy said it welcomes co-funders and cast the possibility of peers pledging parallel funds as a benefit rather than competition.

What to Watch

The milestone-based grant structure is the right mechanism; it ties disbursement to delivered code, not time served. The signal to watch over the next 12-18 months: whether funded developers produce testable implementations and whether wallet providers begin shipping BIP-360-compatible migration tooling for end users. Soft fork activation signaling from miners and node operators remains the longer-horizon gate. Galaxy's money accelerates the research and tooling layer. The governance layer moves on its own clock.
