Coinbase report warns quantum computing threat looms

A new report commissioned by Coinbase highlights an emerging threat to cryptocurrency: quantum computing. While current blockchains remain secure, the report, authored by an independent advisory board, warns that future fault-tolerant quantum computers could break existing encryption. The industry must begin preparing now for this plausible, though uncertain, future threat. Transitioning to quantum-resistant cryptography presents significant challenges, including larger data sizes, increased costs, and complex migration processes for wallets and exchanges. The report suggests exploring gradual transition strategies and hybrid systems to ensure future security without compromising current performance.
