Deep Tide TechFlow News, April 21 — Coinbase's Quantum Computing and Blockchain Independent Advisory Committee released its first position paper stating that sufficiently powerful quantum computers could potentially crack the cryptographic mechanisms used to protect digital assets on mainstream blockchains in the future. However, such devices do not currently exist, and digital assets remain secure for now. The industry should begin preparing for quantum resistance upgrades now.

The document points out that there is no substantial risk to Bitcoin mining, hash functions, and on-chain historical records; the main vulnerabilities are in digital signatures at the wallet level.
Ethereum has proposed a relatively clear migration roadmap, while Solana, Algorand, and Aptos have already begun offering or planning quantum-resistant solutions.
