Coinbase Outlines Bitcoin’s Quantum Security Challenges
Coinbase says preparing Bitcoin for quantum-resistant security will require more than a change to its signature algorithm.

Coinbase has outlined technical and operational challenges Bitcoin would need to address in a transition to quantum-resistant security. The company says it holds roughly 5% of the total bitcoin supply in custody.
Its central point is that replacing Bitcoin’s signature algorithm alone would not be sufficient. Making quantum-resistant protection practical would require addressing broader migration hurdles.
The assessment highlights the complexity of preparing Bitcoin for quantum-computing risks. For a custodian with Coinbase’s stated holdings, that transition would involve both cryptographic changes and operational considerations.
