Coinbase Calls for Immediate Bitcoin Quantum-Resistant Upgrade

What happened: Coinbase published a blog post outlining five technical recommendations for transitioning Bitcoin to quantum-resistant cryptography. The post, authored by Shashank Agrawal, emphasizes the urgency of preparing for quantum computers, referencing Google research that suggests a cryptographically relevant quantum computer could exist by 2029. Coinbase, which holds about 5% of all bitcoin (valued at over $80 billion), recommends flexible signatures, hybrid spending paths, and separating the dormant coins debate from the technical upgrade process.

Why it matters: As one of the largest institutional custodians of bitcoin, Coinbase’s call to action could accelerate community debate and technical development around Bitcoin’s long-term security. The explicit separation of the lost coins debate from the technical upgrade is designed to avoid political deadlock. This intervention underscores the growing institutional concern about quantum threats and the need for proactive, consensus-driven protocol upgrades.
