Nine financial and technology companies have pledged a combined $15 million over three years to fund bitcoin security research and developer work, forming the Bitcoin Security Consortium with post-quantum cryptography as its first priority.
The consortium brings together Strategy, BlackRock, Coinbase, Galaxy, Fidelity Digital Assets, Anchorage Digital, ARK Invest, Block and Blockstream. Its members span bitcoin custody, asset management, payments, infrastructure and trading services, giving the initiative backing from companies whose businesses rely on the network remaining secure and operational over long time horizons.
According to the group’s joint statement, the consortium will support organizations already working on bitcoin’s technical defenses rather than directing the network’s development. Brink executive director Mike Schmidt will coordinate day-to-day work in a volunteer role.
Each member will distribute its own pledged money independently to projects and organizations it chooses. That structure avoids creating a central treasury with authority over bitcoin development, while allowing firms to align their grants around common security priorities.
Quantum preparedness leads the initial agenda
The group’s first area of focus is research into post-quantum cryptography: cryptographic systems designed to withstand attacks from sufficiently powerful quantum computers.
Bitcoin’s current security model relies on public-key cryptography. In normal use, a holder signs a transaction with a private key, while the corresponding public key allows the rest of the network to verify that signature. A large enough quantum computer could theoretically use algorithms such as Shor’s algorithm to derive private keys from exposed public keys, undermining cryptographic assumptions used by bitcoin and many other digital systems.
The consortium said quantum computers capable of breaking contemporary cryptography may still be years away. Its decision to fund work now reflects the difficulty of changing security systems in a global network where software must be designed, reviewed, tested and adopted across wallets, custodians, miners and other infrastructure providers.
Bitcoin protocol changes are especially slow by design. The network has no central operator that can impose an upgrade on users, and security-sensitive changes typically face lengthy technical review before software providers and node operators choose whether to adopt them. Research completed well before a threat emerges would give developers more time to evaluate options without making rushed changes to bitcoin’s consensus rules.
The consortium stated that it will not participate in bitcoin protocol governance, endorse particular protocol modifications or claim to represent the open-source development community. That limitation addresses a longstanding concern around corporate involvement in bitcoin: firms can fund technical work, but bitcoin’s rules remain subject to voluntary adoption by its distributed users and operators.
Corporate funding adds to Galaxy’s quantum program
Galaxy has already launched a separate Bitcoin Quantum Readiness Initiative, committing up to $5 million for developer grants and research related to post-quantum tools. The company’s program and the new consortium both place quantum resilience alongside more immediate bitcoin security work rather than treating it as a distant theoretical issue.
Funding can support several stages of preparation, including cryptographic research, wallet design, migration tools and testing environments. A future shift to quantum-resistant signatures would involve more than changing code in Bitcoin Core. Wallet providers and custodians would need safe ways to move funds into addresses using updated protections, while users would need clear guidance on managing keys and avoiding preventable loss during any migration.
The risk is uneven across bitcoin holdings. Public keys are revealed when funds are spent from many common address types, creating a possible target if quantum computers become capable of deriving private keys quickly enough. Coins held in addresses where a public key has not yet been exposed present a different technical profile. Any practical response would therefore need to account for bitcoin’s variety of address formats, wallet practices and long-dormant holdings.
Project Eleven, a quantum-computing security firm, previously estimated that about 6.9 million BTC could be exposed if cryptographically relevant quantum computers arrive around 2030. Such forecasts depend heavily on assumptions about hardware progress, error correction and the speed at which a machine could perform a useful attack, leaving the timeline uncertain by several years.
Public-sector quantum programs could widen available research
The consortium’s launch follows a wider push to develop quantum technology and quantum-resistant encryption. In June, the U.S. administration issued executive orders intended to accelerate domestic quantum-computing capacity and require federal agencies to complete a transition to post-quantum cryptography for high-value systems by 2031.
Bitcoin was not named in those orders, and federal migration plans do not determine how the open-source network will respond to quantum risks. They could nevertheless expand technical expertise, standards work and implementation experience around post-quantum systems that bitcoin developers may later assess.
For the nine consortium members, the immediate commitment is relatively modest compared with their combined scale, but its structure is more consequential than a one-off grant. It ties several major bitcoin-facing firms to a three-year funding effort while explicitly preserving the independence of protocol development.
The initiative also puts practical pressure on the industry to prepare for a transition that may take longer than the underlying threat takes to arrive. Research into quantum-resistant signatures, safe wallet migration and compatibility with existing bitcoin infrastructure would need to mature before the network could make an informed decision about any eventual upgrade.
