Nine major financial and cryptocurrency companies have launched the Bitcoin Security Consortium, a new initiative dedicated to supporting Bitcoin security research and open-source development. The founding members have pledged a combined $15 million over three years to fund the effort.

According to a report cited by the source, the consortium includes BlackRock, Coinbase, Strategy, Anchorage Digital, ARK Invest, Block, Blockstream, Fidelity Digital Assets, and Galaxy. Collectively, these nine firms span asset management, custodianship, trading, software development, and corporate Bitcoin holdings. Several of the members — including BlackRock, Fidelity, and ARK Invest — now operate spot Bitcoin exchange-traded funds, giving them a direct commercial stake in the network's long-term integrity.

Funding Structure and Governance

The consortium will not manage or distribute any of the committed capital. Instead, each member will independently decide which developers, researchers, and organizations to sponsor. The organization also stated that it will not oversee Bitcoin development or take positions on protocol change proposals.

Robert Mitchnick, BlackRock's head of digital assets, described the work of Bitcoin Core developers as "incredibly important" and said the initiative will channel additional funding into Bitcoin security.

The announcement did not disclose individual contribution amounts, initial grant recipients, or what share of the funding represents new commitments versus repackaged existing efforts.

Quantum Computing Threats Drive Early Preparation

The initiative will also examine risks associated with advances in quantum computing. While quantum computers capable of breaking Bitcoin's encryption do not yet exist, developers have already begun researching protective measures, as network upgrades can take several years to design, coordinate, and implement. The specific concern centers on Bitcoin's use of the Elliptic Curve Digital Signature Algorithm (ECDSA) for transaction signatures, which sufficiently powerful quantum computers running Shor's algorithm could theoretically compromise.

Separately this week, Galaxy announced a $5 million fund dedicated to quantum-resistant signatures, wallet migration tools, and security audits. It remains unclear whether this amount is included in the consortium's $15 million pledge or represents additional funding under Galaxy's own Bitcoin Security Improvement Program.

One proposed upgrade currently under discussion is BIP 360, which introduces a new output type designed to reduce public-key exposure. Other researchers are exploring post-quantum signature schemes and solutions for Bitcoin held in addresses with exposed public keys.

Scale of the Quantum Vulnerability

Research by CryptoQuant, cited by Galaxy, estimates that approximately 6.9 million Bitcoin could be vulnerable to quantum-based attacks. Addressing this exposure will require not only technical solutions but also broad coordination across the Bitcoin ecosystem, a process likely to extend over several years.

Mike Schmidt of Brink will lead the consortium's efforts in a voluntary capacity. The organization plans to publish regular materials on the current state of Bitcoin security research, providing public visibility into the progress being made.

Context and Accountability

Existing organizations such as OpenSats and the Human Rights Foundation's Bitcoin Development Fund already provide grants to open-source Bitcoin developers, and Bitcoin Core has historically relied on a relatively small group of funded contributors supported by entities like Brink and Chaincode Labs. Because Bitcoin has no central company or foundation that employs its core developers, coordinated funding initiatives have taken on particular significance for sustaining protocol maintenance. The consortium's effectiveness will ultimately be measured by the fulfillment of its pledges, with named backers, identified recipients, and verifiable fund deployments serving as indicators of how much capital reaches active research projects.
