Bitcoin giants unite with $15M plan to fight quantum threat Strategy, BlackRock, Coinbase and six other companies have formed the Bitcoin Security Consortium to fund work on Bitcoin’s long-term security. - Nine major firms pledged $15 million over three years to support Bitcoin security research worldwide. - Post-quantum cryptography leads the consortium’s agenda, although no capable attack system currently exists anywhere. - Members will fund chosen developers independently without directing Bitcoin’s protocol changes or its open-source community. The founding members pledged a combined $15 million over three years for developers, researchers and organizations working on the network. The other members are Anchorage Digital, ARK Invest, Block, Blockstream, Fidelity Digital Assets and Galaxy. Brink Executive Director Mike Schmidt will coordinate the group’s daily work as a volunteer. Each company will choose where to direct its own funding rather than pay into one shared pool. Consortium targets Bitcoin’s long-term security The consortium named post-quantum cryptography as its first area of focus. This field develops methods designed to resist attacks from classical and quantum computers. Bitcoin currently relies on elliptic curve cryptography to prove ownership and authorize transactions. Large-scale quantum computers cannot break Bitcoin’s cryptography today. However, a powerful enough machine running Shor’s algorithm could derive a private key from an exposed public key. An attacker could then try to move funds from a vulnerable address. Researchers still disagree on when such a machine could exist. “As long-term holders, we have every incentive to see Bitcoin remain secure for generations,” said Strategy CEO Phong Le. BlackRock global head of digital assets Robert Mitchnick also said the member firms will make more funding available for Bitcoin Core developers and long-term security work. Members will not control Bitcoin development The group said it will not develop or direct Bitcoin’s protocol, endorse specific changes or speak
