Nine firms, including BlackRock, Coinbase, Strategy, Anchorage Digital, ARK Invest, Block, Blockstream, Fidelity Digital Assets, and Galaxy, have pledged a combined $15 million over three years to fund Bitcoin security research and open-source development. The group announced itself as the Bitcoin Security Consortium on July 23, 2026, with quantum computing threats listed as a core area of focus.
How the money flows, and who controls it
The consortium will not pool or redistribute the capital. Each member decides independently which developers, researchers, or organizations to support. That means no central fund, no committee sign-offs, and no disclosed breakdown of who is contributing what. The announcement named no initial recipients and gave no split between fresh commitments and money already in motion.
Robert Mitchnick, BlackRock's head of digital assets, described Bitcoin Core developers as doing "incredibly important work" and framed the initiative as a way to channel more sustained funding toward security. The consortium also stated it would take no position on protocol change proposals and would not attempt to direct Bitcoin's development roadmap.
Galaxy separately announced a $5 million program focused on quantum-resistant signatures, wallet migration tools, and security audits. Whether that $5 million sits inside the $15 million figure or on top of it has not been clarified, so the real total of new funding remains unknown.
The quantum threat is not here yet, but the clock is already running
No quantum computer capable of cracking Bitcoin's elliptic-curve encryption exists today. Developers are working on defenses anyway, because any meaningful network upgrade can take years to move from proposal to activation. One proposal currently under discussion is BIP 360, which introduces a new output type designed to limit public-key exposure. Researchers are also exploring post-quantum signature schemes and methods for migrating coins held in addresses where public keys are already visible on-chain.
The scale of the problem is significant. CryptoQuant data cited by Galaxy estimates roughly 6.9 million Bitcoin could be vulnerable to a sufficiently powerful quantum attack. Beyond the technical fixes themselves, migrating that much supply would require a level of network-wide coordination that no upgrade in Bitcoin's history has ever had to manage. The consortium's funding is aimed at getting the groundwork done well before that scenario becomes urgent.
