Coinbase Releases Bitcoin Quantum-Resistance Upgrade Recommendations: Calls for Early Planning of a Multi-Year Migration Path

PANews reported on October 13 that Coinbase published a technical discussion article on Bitcoin's post-quantum readiness, stating that Bitcoin needs to proactively address the cryptographic risks quantum computing may pose in the future and recommending that the community begin migration preparations as early as possible.

Coinbase believes that Bitcoin's quantum-resistant upgrade involves not only selecting a new quantum-resistant signature algorithm, but also comprehensively considering block space constraints, full-node verification capabilities, institutional custody needs, ordinary wallet compatibility, and solutions for funds that cannot be migrated. Bitcoin should consider introducing an output structure that supports quantum-resistant signatures and explore hybrid approaches, such as allowing the same funds to have both traditional ECDSA/Schnorr signatures and quantum-resistant signatures as two authorization paths, to achieve a smooth transition.

In addition, Coinbase emphasized that quantum-resistant migration will take many years, and the community should complete preparations before the quantum computing threat actually emerges. For BTC funds that have not been migrated for a long time, have lost private keys, or have exposed public keys, Coinbase believes that solutions still need to be found through governance and technical discussions.
