Bitcoin Consortium Pledges $15M for Quantum Readiness

Nine major firms commit $15 million to Bitcoin security research

A coalition of nine leading crypto and financial firms has announced a coordinated effort to bolster Bitcoin's long-term security against future threats, with an initial pledge totaling $15 million over three years. The group — calling itself the Bitcoin Security Consortium — will fund research, tools and audits focused on preserving Bitcoin’s cryptographic integrity as the industry braces for potential advances in quantum computing.

The consortium’s founding backers include BlackRock, Coinbase, Strategy, Anchorage Digital, ARK Invest, Block, Blockstream, Fidelity Digital Assets and Galaxy. Brink Executive Director Mike Schmidt has volunteered to coordinate the consortium’s day-to-day activities. Importantly, each firm will direct its own grants rather than contributing to a single pooled fund, preserving independent decision-making about recipients.

Who will receive funding and how it will be distributed

Members said the dollars are targeted at developers, open-source researchers and nonprofit organizations working on Bitcoin Core, wallet security, cryptographic research and other foundational infrastructure. The consortium emphasized it will not dictate protocol changes or speak for Bitcoin developers — instead, funds will support work that the community can independently debate, test and adopt through Bitcoin’s established governance processes.

This decentralized funding model is meant to avoid central control over the protocol while accelerating technical research into long-term defenses for users, exchanges, custodians and institutional holders.

Post-quantum cryptography is the immediate focus

The consortium named post-quantum cryptography (PQC) as its first priority. PQC develops algorithms and signatures designed to withstand attacks from both classical and quantum computers. Today Bitcoin relies on elliptic curve cryptography (ECC) to validate ownership and authorize transactions. While there is no known large-scale quantum computer capable of breaking ECC today, a sufficiently capable machine running Shor’s algorithm could, in principle, derive a private key from an exposed public key and move funds from vulnerable addresses.

Industry and academic researchers continue to debate when such quantum capability might appear. Estimates vary, but the consortium and other participants say proactive investment in migration tools, signing schemes and wallet upgrades will reduce future risks and shorten response times if a threat materializes.

Practical engineering and migration work

Planned funding areas include post-quantum signature libraries, wallet migration systems, security audits, and infrastructure engineering that lowers network exposure. Developers are already exploring technical proposals such as BIP-360, which would add new Bitcoin output types to limit future quantum exposure, and institutional custody providers are testing hybrid signing systems combining classical and post-quantum algorithms.

For example, BitGo and Silence Laboratories completed a simulation incorporating a post-quantum signing system into an institutional custody workflow, illustrating how exchanges and custodians might adopt new cryptography without disrupting large-scale operations.

Estimates of exposed Bitcoin vary

Quantifying Bitcoin at risk depends on definitions and address types. Project Eleven’s Bitcoin Risq List estimated roughly 6.98 million BTC were associated with addresses that reveal public keys as of mid-June 2026. That figure includes older address formats and instances of address reuse. Project Eleven’s baseline projection for a hypothetical “Q-Day” — when a quantum computer could feasibly break current public-key cryptography — sits near 2033, with scenarios ranging from 2030 to 2042.

Other analytics firms use narrower criteria. Glassnode estimated in May that about 1.92 million BTC face structural exposure because their output types reveal public keys by design, and an additional 4.12 million BTC are operationally exposed due to address reuse and wallet practices. Crucially, these trackers do not imply that present-day hardware can steal those coins; they instead aim to quantify potential vulnerability if quantum capability advances.

Government and industry responses

The U.S. government has also accelerated planning: a June executive order directed federal agencies to migrate high-value systems to post-quantum key establishment by the end of 2030 and adopt post-quantum digital signatures by the end of 2031. Private firms are moving in parallel. Galaxy announced a separate Bitcoin Quantum Readiness Initiative with up to $5 million in grants for tools, migration systems, signature research and audits and created an advisory council to guide that work.

Coinbase’s independent advisory board has urged Bitcoin developers to begin planning migration strategies now, while stopping short of endorsing prescriptive rules about legacy or vulnerable coins. The advisory board’s recommendation emphasizes preparedness and technical work prior to any practical threat.

What this means for Bitcoin users and developers

For Bitcoin users, the immediate takeaway is that major custodians, exchanges and institutional holders are taking the quantum threat seriously and allocating resources to mitigate future risk. Users should follow best practices: avoid address reuse, prefer newer output types when possible, and keep wallets updated as post-quantum-safe options are developed.

For developers and the open-source Bitcoin community, the consortium’s funding represents additional resources to accelerate research, audits and code that will be reviewed through existing Bitcoin Core processes. The group has been explicit that it will not propose or impose protocol changes; decisions will remain community-driven.

Next steps and transparency

The Bitcoin Security Consortium said it will publish updates, educational material and technical briefings to inform investors, the media and the public about progress in post-quantum research and other security projects. It has not yet disclosed individual grant recipients, specific contribution amounts by member, or any timeline for protocol upgrades.

As quantum readiness initiatives expand across industry and government, coordinated funding and independent grants could speed development of migration tools, signature research and audits that preserve Bitcoin’s security model. For long-term holders, exchanges and institutional participants, proactive investment today aims to ensure Bitcoin remains resilient across generations of cryptographic change.

The consortium’s pledge is a notable step toward community-aligned preparedness: providing resources while respecting the decentralized process that governs Bitcoin’s technical evolution, and prioritizing research that can be independently evaluated by developers and auditors worldwide.
