Deep Tide TechFlow News, February 19 — According to Decrypt, Coinbase CEO Brian Armstrong stated in a CNBC interview that quantum computing will not “break blockchain,” but is a “very solvable issue,” and pointed out that the industry has enough time to upgrade encryption standards.

Armstrong revealed that Coinbase has established a Quantum Computing Advisory Committee, including quantum expert Scott Aaronson, cryptographer Dan Boneh, Ethereum researcher Justin Drake, and others. The committee regularly communicates with major blockchains to develop post-quantum cryptography migration pathways. The committee will release risk assessment reports and migration strategies.

The article notes that although quantum computers could theoretically crack current public key encryption (such as SHA-256 used for Bitcoin private keys), current quantum machines are far from posing a threat, and upgrading encryption is relatively easy. Vitalik Buterin urged developers not to delay adopting quantum-resistant cryptography; Solana has tested quantum-resistant signatures on its testnet; Bitcoin developers are advancing proposals like BIP 360 to reduce quantum exposure pathways; the Ethereum Foundation also prioritizes post-quantum security as a strategic goal.
