Wall Street firms pledge $15m to shield Bitcoin from quantum risk
Nine major financial institutions have formed a $15 million consortium to fund Bitcoin security research, aiming to preempt a future quantum computing threat that could endanger millions of coins held by investors.
A group of nine financial institutions, including BlackRock, Coinbase, and Strategy, has committed $15 million over three years to establish the Bitcoin Security Consortium. The initiative will fund open-source development and research into post-quantum cryptography to protect the network against future technological advances.
While quantum computers capable of breaking Bitcoin’s cryptographic defenses do not currently exist, the financial stakes of a future breach are immense. Research from CryptoQuant indicates roughly 6.9 million bitcoin could be vulnerable if sufficiently powerful quantum machines are eventually built. For institutional investors holding large bitcoin reserves, this long-term systemic risk requires proactive mitigation.
Defending the network presents a unique logistical challenge due to Bitcoin’s decentralized structure. Upgrading infrastructure across wallets, exchanges, miners, and individual users could take years and demands extensive technical coordination. Developers are already evaluating proposals like BIP 360, which would introduce a new output type to limit public key exposure. Other approaches under discussion involve post-quantum signature schemes and methods to secure coins held in older, already-exposed addresses.
To avoid centralizing control over Bitcoin’s development, the consortium will not actually hold or allocate the $15 million. Instead, member firms will independently direct their capital to chosen developers and research organizations. The group explicitly stated it will not influence Bitcoin governance or take positions on proposed protocol changes.
The consortium plans to publish regular reports tracking the state of Bitcoin security to keep investors and the public informed. “Bitcoin Core developers do incredibly important work,” said Robert Mitchnick, head of digital assets at BlackRock. He added that the group's primary focus is making additional funding available for the network's long-term security.
The initial announcement left several financial details opaque. It did not disclose individual company contributions, the first grant recipients, or how much of the $15 million represents entirely new commitments rather than redirected existing funding. Separately, Galaxy launched a distinct $5 million initiative this week focused on quantum-resistant signatures, wallet migration tools, and security audits. The consortium did not clarify whether Galaxy's separate pledge is included in its $15 million total.
Mike Schmidt, executive director of Bitcoin developer funding nonprofit Brink, will coordinate the consortium’s efforts on a volunteer basis. The broader membership spans traditional finance and crypto-native firms, also including Anchorage Digital, ARK Invest, Block, Blockstream, and Fidelity Digital Assets.
