Bitcoin’s security may need an upgrade sooner than many expect, according to Anatoly Yakovenko, co-founder of Solana.

Speaking at the All-In Summit 2025, Yakovenko warned there is roughly a 50/50 chance of a major quantum-computing breakthrough within the next five years and urged the Bitcoin community to start shifting to quantum-resistant signatures now.

Quantum Risk On A Short Timeline

According to reports, Yakovenko argued that advances in quantum hardware — helped along by rapid progress in AI — could reach a point where current cryptography used by Bitcoin becomes vulnerable by about 2030.

He recommended migrating away from Bitcoin’s existing signature scheme, ECDSA, toward algorithms designed to resist quantum attacks.
