[Coinbase Releases Post-Quantum Security Migration Strategy Recommendations for Bitcoin] Coinbase has published an article discussing migration strategies for Bitcoin to address threats posed by quantum computing, recommending the adoption of hybrid transition constructions and flexible output architectures to ensure asset security. Coinbase holds approximately 5% of the global BTC and has already joined the Bitcoin Security Alliance while investing in open-source research. Key recommendations include adopting flexible output architectures such as P2MR or P2TRv2, implementing 1-of-2 hybrid transition constructions, prioritizing support for stateless signature schemes, and requiring candidate solutions to possess MPC (multi-party computation) compatibility.
