Galaxy Digital Launches Bitcoin Quantum Readiness Initiative
Insider Brief
- Galaxy Digital has started the Bitcoin Quantum Readiness Initiative, which will allocate up to $5 million for quantum security research, developer grants, and an advisory board.
- The goal of this initiative is to tackle potential quantum computing threats to Bitcoin’s cryptographic framework.
- The program will emphasize post-quantum cryptography research, tools for migration, and partnerships with researchers and Bitcoin developers.
Galaxy Digital has introduced the Galaxy Bitcoin Quantum Readiness Initiative, committing $5 million for developer grants, focused research initiatives, and establishing an advisory board to safeguard Bitcoin’s cryptographic integrity from forthcoming quantum computing threats.
The digital asset company, marked on Nasdaq as GLXY, unveiled a three-part initiative on Tuesday, addressing rising concerns regarding quantum computing advancements and Bitcoin’s lag in adopting post-quantum cryptographic practices.
“There’s a clear disparity between the fast-paced advancements in quantum computing and Bitcoin’s initial approach to post-quantum cryptography,” remarked Alex Thorne, head of research at Galaxy. “Galaxy’s mission is to bridge that gap through insightful research for investors and policymakers, alongside grants that assist developers in tackling the more challenging technical aspects.”
“As a prominent player in the digital asset space, it’s essential for us to contribute solutions to the potential threats that quantum computing presents to Bitcoin,” stated Galaxy’s founder and CEO, Mike Novogratz.
Overview of the Initiative
The initiative unfolds over three focus areas. The first is grant funding, aimed at funding proposals for quantum-proof transactions, post-quantum signature systems, and tools for wallet and custodian migrations. Applications are open immediately.
The second area involves expanding research programs. Through Galaxy Research, the company releases analysis on quantum threats for institutional investors, policymakers, and developers. The third component is a quantum advisory council, which will guide grant decisions and research directions. An initial council member is Barry Saunders, a professor and scientific director of the University of Calgary’s Quantum City, along with Damien Berube, an MIT Sea Grant Knauss Research Fellow, and Elan Tromer, a computer science professor at Boston University.
Saunders pointed out that the timeline for quantum capabilities “continues to tighten,” affecting Bitcoin as well, with preparations already in motion within governments and industries.
The Challenges Facing Bitcoin
Bitcoin’s security relies on elliptic curve cryptography, specifically the secp256k1 curve. The mathematical challenge that ensures ECC’s security (deriving a private key from a public key) proves computationally unfeasible for classical computers. However, with a quantum computer leveraging Shor’s algorithm, this difficulty could vanish.
Urgency around these issues has escalated. In March 2026, a study by Google Quantum AI, the Ethereum Foundation, and Stanford University indicated that the quantum resources necessary to breach secp256k1 might be significantly less than previously thought. Under certain hardware conditions, a quantum computer could theoretically intercept a live Bitcoin transaction and derive a private key in roughly 9 minutes during Bitcoin’s 10-minute block confirmation period. While these are just theoretical calculations based on non-existent hardware, they certainly raise alarms.
This specific attack method, known as an on-spend attack, places Bitcoin’s risk in a different category compared to other crypto threats. When a transaction is broadcast, the public key is briefly visible before finalization. A sufficiently fast, reliable quantum computer could capture that private key during this window and execute competing transactions at higher fees, draining the wallet almost instantly. This scenario requires only a few minutes, unlike needing years of data storage.
The risks aren’t evenly distributed either. Approximately 6.9 million Bitcoins (nearly a third of the total supply) are held in wallets with their public keys already permanently on-chain. According to Google’s research, this includes the initial Pay-to-Public-Key (P2PK) addresses where funds were previously utilized. The public keys for 1.7 million Bitcoins in early P2PK addresses—some associated with Satoshi Nakamoto—have been exposed on the blockchain for more than a decade, unlike financial institutions that regularly renew their encryption keys.
Growing Industry Response
The Galaxy initiative coincides with increased institutional engagement. BitGo has recently introduced quantum risk management features for institutional Bitcoin wallets, including quantum risk scores and revised UTXO selection procedures to minimize key exposure. In its Q2 2026 report, Blockstream pinpointed post-quantum cryptography as a major engineering priority. Project Eleven anticipates Q-Day for quantum potential in 2033, with an optimistic outlook for 2024 and a more cautious one for 2030.
On the protocol front, Bitcoin Improvement Proposals 360 and 361 lay out a plan for migration. BIP-360 suggests a new address format (Pay-to-Merkle-Root) that prevents public key exposure on the blockchain. A paper released in April 2026 by Jameson Ropp and others maps out a three-step migration strategy that could freeze coins in wallets that don’t adapt. Both proposals have sparked considerable debate within the Bitcoin developer community. Modifying Bitcoin’s fundamental protocol necessitates broad agreement among miners, node operators, and developers, often taking years even for less contentious upgrades.
These governance challenges are part of what Galaxy aims to tackle. The company stated that delaying action until quantum computers pose a threat would leave insufficient time for the network’s response. While no cryptographically relevant quantum computers exist at present, Galaxy emphasized the importance of proactive preparation.
From the governmental perspective, President Trump signed two executive orders on June 22, 2026. One aims to expedite U.S. quantum technology advancements, while the other establishes deadlines: December 31, 2030, for federal post-quantum cryptography key establishment and December 31, 2031, for digital signatures.
For organizations managing Bitcoin assets, TQI provides extensive coverage regarding quantum threats to cryptocurrencies and the challenges of transitioning to post-quantum structures, detailing both technical and operational concerns.
