Coinbase has officially launched the Bitcoin Security Consortium, bringing together major financial and crypto firms to prepare Bitcoin's infrastructure for the eventual threat of quantum computing. The consortium includes BlackRock, Fidelity Digital Assets, Block, Blockstream, Strategy, Galaxy, Anchorage Digital, and ARK Invest. Together, they have committed a combined $15 million over three years to fund open-source developers, researchers, and organizations working on Bitcoin's long-term security.
Coinbase CEO Brian Armstrong emphasized that while quantum computers do not currently pose an immediate risk to Bitcoin, the time to prepare is now, before fault-tolerant quantum machines become a reality. The company's own Independent Advisory Board on Quantum Computing and Blockchain has concluded that blockchain cryptography will eventually require replacement, though no firm timeline exists.
To that end, Coinbase is building PQ-CoreKMS, a post-quantum key management system that currently safeguards about 99.9% of customer custody assets. Within the next year, the firm plans to deploy an automated signing pipeline using secure enclaves, threshold cryptography, and secret-sharing technologies. Over the following two to three years, it intends to expand multiparty computation capabilities to support lattice-based and other post-quantum signature algorithms. Coinbase is also cataloging every cryptographic system across its business and reviewing Ethereum's post-quantum roadmap for its Layer-2 network, Base.
In parallel, the consortium will co-host a Bitcoin post-quantum working session with Stanford University this August, convening Bitcoin Core developers, researchers, and cryptographers to discuss migration strategies. Coinbase has pledged to dedicate engineering resources to open-source work, including support for proposals like BIP-360 and other Bitcoin migration efforts. The move aligns with broader industry trends—the U.S. National Institute of Standards and Technology (NIST) released updated draft post-quantum cryptography standards in June 2026, aimed at helping agencies and companies adopt quantum-resistant technologies.
