The Coinbase Independent Quantum Advisory Council, including researchers from the Ethereum Foundation, Stanford, and other institutions, published a position paper on April 21, 2026, highlighting the risks quantum computers pose to blockchain cryptography. The report emphasizes the need for preventive measures before Q-Day, when quantum computers could potentially compromise current cryptographic systems.
Coinbase has warned that proof-of-stake chains like Ethereum and Solana could face quantum risks, as validator signatures and wallet cryptography may become vulnerable if future quantum computers break current encryption. The advisory highlights potential security concerns, emphasizing the need for blockchain projects to prepare for advancements in quantum computing that could compromise cryptographic protections.
