Crypto financial services firm Galaxy Digital has established a $5 million Bitcoin Quantum Readiness Initiative (BQRI) to fund developers working on defenses against the emerging threat of quantum computing to Bitcoin and other blockchain networks. The program, announced on July 21, 2026, aims to accelerate the development and adoption of quantum-resistant cryptographic standards before the technology advances to the point where it could compromise the security of the Bitcoin network.
Quantum computing represents a paradigm shift in computational power, leveraging quantum mechanical phenomena such as superposition and entanglement to solve certain mathematical problems exponentially faster than classical computers. While still in its early stages, the technology poses a specific threat to the cryptographic algorithms that underpin Bitcoin, Ethereum, and most other cryptocurrencies. Bitcoin relies on two primary cryptographic mechanisms: the SHA-256 hashing algorithm used for mining and the Elliptic Curve Digital Signature Algorithm (ECDSA) used for signing transactions. Quantum computers, once sufficiently powerful, could in theory break ECDSA by solving the discrete logarithm problem and thereby allow an attacker to forge digital signatures. This would enable theft of funds from any address that has broadcast a transaction, exposing the owner's public key.
The Scope of the Threat
Researchers have estimated that as much as 6.9 million bitcoin — worth approximately $461 billion at current prices near $63,400 — could be at risk if quantum computers become capable of breaking ECDSA before mitigations are in place. This figure includes coins stored in addresses that have ever been used to send a transaction (i.e., those with exposed public keys). The threat is not imminent: current quantum computers, such as those developed by Google, IBM, and others, have only a few hundred qubits and cannot break real-world cryptographic systems. However, the timeline for a sufficiently powerful quantum computer — often referred to as a cryptographically relevant quantum computer (CRQC) — is uncertain, with estimates ranging from a decade to several decades. Given the decade-long effort required to upgrade a decentralized network like Bitcoin, early action is essential.
Galaxy Digital, led by founder and CEO Mike Novogratz, has positioned itself at the intersection of crypto finance and institutional adoption. The BQRI will provide grants to developers and researchers working on several key areas: quantum-resistant signature schemes, wallet migration tools and security audits. The fund seeks additional backing from other crypto firms, exchanges, and industry stakeholders to pool resources and speed the adoption of new cryptographic standards. This collaborative approach mirrors earlier efforts in the crypto community, such as the Ethereum Foundation’s post-quantum cryptography research or the Bitcoin Improvement Proposal (BIP) process that has upgraded Bitcoin’s scripting capabilities over time.
Technical Challenges and Ongoing Research
Developing quantum-resistant signatures for Bitcoin is not straightforward. Bitcoin’s protocol has a fixed scripting language and a UTXO model that does not easily support arbitrary signature schemes. Proposals such as Lamport signatures, Winternitz one-time signatures, or lattice-based schemes (like CRYSTALS-Dilithium, recently selected by NIST as a post-quantum standard) must be carefully integrated without disrupting existing wallets, miners, and full nodes. Additionally, any upgrade requires consensus among network participants, a process that can be slow and contentious. The Bitcoin community has historically been cautious about changes to the protocol, preferring conservative upgrades that maintain security and decentralization.
Wallet migration tools are equally important. Even if Bitcoin upgrades to support quantum-resistant addresses, users must move their funds from old (exposed) addresses to new ones. This process requires secure, user-friendly software that prevents loss of funds and minimizes disruption. Galaxy’s initiative will fund projects that build these migration utilities, as well as conduct security audits of proposed cryptographic implementations. The fund will also support educational efforts to inform the broader crypto community about the risks and necessary steps.
Quantum computing is not just a threat to Bitcoin; it also jeopardizes Ethereum, which uses the same ECDSA for its accounts, though Ethereum’s transition to proof-of-stake and its more flexible execution environment may make upgrades slightly easier. Other chains that rely on similar elliptic curve cryptography face the same risks. However, Bitcoin’s larger market cap and more rigid protocol make it a particularly urgent case.
Industry Response and Context
Galaxy’s move is one of the first major industry-backed initiatives specifically targeting quantum readiness for Bitcoin. While academic research and open-source projects have been exploring post-quantum cryptography for years, practical deployment has lagged. In 2024, the Bitcoin network processed over 100 million transactions, and the cumulative value of bitcoin transferred on-chain exceeds $50 trillion. Any vulnerability that allows quantum-powered theft could undermine trust in the entire crypto ecosystem. The BQRI is designed to preempt a crisis by funding development now, rather than reacting after a breakthrough.
The timing of Galaxy’s announcement coincides with increased attention on quantum computing from both the public and private sectors. In 2025, the U.S. National Institute of Standards and Technology (NIST) finalized its set of post-quantum cryptographic algorithms, including CRYSTALS-Kyber for key exchange and CRYSTALS-Dilithium for digital signatures. These standards provide a basis for blockchain upgrades, but adapting them to Bitcoin’s specific constraints remains an engineering challenge. Galaxy’s fund aims to bridge the gap between academic standards and practical deployment.
Some industry observers note that the threat is still distant, but preparing early is prudent. “Quantum computing is a classic example of a low-probability, high-impact risk,” said Dr. Sarah Thompson, a cryptographer at MIT who specializes in post-quantum cryptography, in a recent interview. “The difficulty is that we don’t know when the transition will happen, but we know it will take years to implement on a decentralized network. Starting now is the responsible choice.” Thompson is not affiliated with Galaxy but has advised the BQRI informally.
Galaxy Digital’s Broader Role
Galaxy Digital, headquartered in New York, is a diversified financial services firm serving the crypto sector. It offers trading, asset management, investment banking, and advisory services. The firm went public in 2018 via a reverse takeover of a Canadian shell company and has since grown to manage over $5 billion in assets under management (as of June 2026). Under Novogratz, who previously worked at Fortress Investment Group, Galaxy has been an outspoken advocate for crypto adoption. The establishment of the BQRI aligns with Galaxy’s mission to secure the infrastructure that underpins the crypto economy.
The $5 million fund will be disbursed over a three-year period, with the first round of grants expected to open in August 2026. Applications will be reviewed by a committee that includes technical experts from Galaxy and external advisors. Galaxy is also reaching out to other crypto firms, such as exchanges and wallet providers, to contribute to the fund. If successful, the BQRI could become a central coordinating body for quantum defense efforts across the industry.
While the immediate risk is low, the potential consequences are staggering. A quantum attack that steals even a fraction of exposed bitcoin could cause panic selling, exchange runs, and regulatory backlash. By investing now, Galaxy is betting that prevention is cheaper and more effective than cleanup. Whether other major players will join remains to be seen, but the initiative represents a significant step toward ensuring Bitcoin’s longevity in a post-quantum world.
