Inside Coinbase’s $250 Billion Playbook for Post-Quantum Bitcoin Custody
Coinbase is preparing for a post-quantum future for Bitcoin, with safeguards designed to support various potential signature schemes. The company, which manages $250 billion in assets, is exploring alternatives to Multi-Party Computation (MPC) if Bitcoin adopts a scheme incompatible with MPC, such as hash-based signatures. Coinbase is also researching a fallback architecture using Hardware Security Modules (HSMs) for key management.
