Galaxy Digital announced on July 21, 2026, its quantum readiness initiative launch for the Bitcoin protocol. The organization committed up to $5 million in grants dedicated to open-source developers building post-quantum cryptographic security infrastructure.
The grants will fund upgrade proposals, post-quantum cryptography schemes, and key migration tooling for software wallets and institutional custodians. Additionally, resources will cover formal technical security audits evaluating proposed protocol modifications.
The funding initiative addresses broader structural concerns regarding quantum computing on digital assets and how advanced hardware might eventually compromise traditional public-key encryption models across decentralized networks.
As part of this program, the entity established a quantum advisory council composed of academic research leaders. This body will coordinate research into migration paths capable of protecting unspent outputs against future technological threats.
The advisory 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.
Analysis of the current network attack surface highlights potential vulnerabilities in specific transaction address types. According to analytics provider Glassnode, approximately 30% of Bitcoin supply could face exposure if cryptographically relevant quantum computers emerge.
Glassnode specifies that 10% of the supply is structurally unsafe due to legacy pay-to-public-key output formats. Furthermore, 20% is operationally unsafe due to private key management practices and historical address reuse.
Debates on migration timelines and encryption standards
In August 2024, the US Department of Commerce National Institute of Standards and Technology published its first post quantum encryption standards. These specifications outline digital signature and key exchange algorithms designed for widespread digital implementation.
Timeline expectations for practical quantum hardware capable of breaking current encryption vary significantly among industry researchers. Views range from several decades of operational runway to much shorter implementation timeframes.
In November 2025, Blockstream CEO Adam Back stated that Bitcoin faces no meaningful quantum threat for at least 20 to 40 years. Back noted this timeframe provides adequate space to integrate official cryptographic standards into the network layer.
Despite differing perspectives, determining the precise threat level remains one of the biggest unknowns regarding long-term network security and signature scheme upgrades.
In December 2025, Blockstream Research released a paper proposing a hash-based signature scheme for Bitcoin. The proposal seeks to replace current ECDSA and Schnorr signatures with mechanisms relying exclusively on cryptographic hash functions.
Conversely, wealth management firm Bernstein stated in an April 2026 report that the Bitcoin network has a three to five year window to execute a post-quantum security upgrade.
Grant-funded projects will focus on addressing transaction size overhead and backwards compatibility constraints associated with post-quantum algorithms. Technical evaluations will determine the viability of proposed upgrades.
The advisory council will regularly review developer progress and audit results as proposals move toward potential Bitcoin Implementation Proposals. This systematic evaluation ensures that candidate solutions meet strict security requirements before implementation.
