Coinbase has launched the Bitcoin Security Consortium with several major industry firms to support Bitcoin's long-term security against potential future risks from quantum computing.

The consortium includes BlackRock, Fidelity Digital Assets, Block, Blockstream, Strategy, Galaxy, Anchorage Digital and ARK Invest. Coinbase said the initiative is intended to fund Bitcoin security research and support developers working on future post-quantum migration proposals.

Coinbase CEO Brian Armstrong said quantum computing does not currently pose a threat to Bitcoin. However, he said preparation must begin before fault-tolerant quantum computers become available. The issue matters for Bitcoin because any change to core cryptographic assumptions would require careful technical review, software implementation and broad adoption across a decentralized network rather than a single operator-led upgrade.

Coinbase Advances Post-Quantum Planning

According to Coinbase, the company formed its Independent Advisory Board on Quantum Computing and Blockchain earlier this year. The board concluded that blockchain cryptography will eventually need to be replaced, although the timing remains uncertain.

Coinbase said one of the largest challenges will be coordinating upgrades across decentralized networks and millions of users. For that reason, the company has begun preparing operational systems rather than waiting until the risk becomes immediate.

The company also announced work on PQ-CoreKMS, a post-quantum version of its proprietary key management platform. Coinbase said CoreKMS currently protects about 99.9% of customer assets held in custody.

Within the next year, Coinbase expects to deploy an automated signing pipeline that uses secure enclaves, threshold cryptography and secret-sharing technologies. The company has also begun reviewing every cryptographic system across its business and is assessing Ethereum's post-quantum roadmap for Base.

Consortium to Support Bitcoin Developers

In addition to its internal work, Coinbase will co-host a Bitcoin post-quantum working session with Stanford in August. The event is expected to bring together Bitcoin Core developers, researchers and cryptographers to discuss migration strategies and technical challenges.

Coinbase said it plans to hold additional sessions on a regular basis as development continues. The company also confirmed that it will commit engineering resources to open-source work supporting proposals including BIP-360 and other Bitcoin migration efforts. For proposals affecting Bitcoin consensus or wallet security, sustained open-source review is typically a central part of evaluating trade-offs before any broad deployment.

Members Commit Funding for Security Work

The Bitcoin Security Consortium brings together BlackRock, Fidelity Digital Assets, Block, Blockstream, Strategy, Galaxy, Anchorage Digital and ARK Invest. According to Cryptopolitan, members of the consortium committed a combined $15 million over three years to support developers, researchers and organizations working on Bitcoin security.

Armstrong said researchers, developers, protocols and companies must work together on post-quantum readiness. The consortium did not disclose individual financial contributions or identify the first projects expected to receive funding.
