Coinbase is proactively upgrading its CoreKMS key management system with post-quantum cryptography capabilities ahead of the inevitable arrival of large-scale quantum computers. This strategic shift involves implementing secure enclaves and threshold cryptography to ensure long-term asset security once blockchain protocols adopt compatible schemes. The move underscores that cryptographic migration must begin immediately, regardless of current timelines for functional quantum hardware breaking existing encryption standards.

Coinbase Details Quantum-Resistant Security Steps

Quantum ZeitgeistJuly 23, 20265 min read

Coinbase is preparing for post-quantum cryptography, acknowledging current blockchain vulnerabilities, and has begun building a post-quantum version of its CoreKMS.

Coinbase protects 99.9% of its custodied assets with its CoreKMS key management system and is now prioritizing an upgrade to prepare for the eventual arrival of quantum computing. While the timeline for a large-scale, cryptography-breaking quantum computer remains uncertain, the company established the Coinbase Independent Advisory Board on Quantum Computing and Blockchain earlier this year to proactively address the looming threat. The Board determined that preparation must begin immediately, regardless of when such a computer is built; as they state, “the debate about timelines is largely irrelevant, because…
