Solana Co-Founder Warns of Quantum Threat to Bitcoin by 2030

At the All-In Summit 2025, Anatoly Yakovenko, co-founder of Solana, issued a significant warning to the Bitcoin community. He highlighted the possibility of a quantum computing breakthrough by 2030 that could compromise Bitcoin's current cryptographic security measures. According to Yakovenko, the existing signature schemes could become obsolete, opening doors for forgery of transactions and wallet compromises.

To mitigate this looming risk, Yakovenko proposed migrating Bitcoin to a quantum-resistant signature scheme. However, such a change would require a hard fork—an update that fundamentally alters Bitcoin's protocol. He emphasized that there is a roughly 50/50 chance that quantum computers could break current protections within five years, raising urgency.

Contrasting this view, experts like Adam Back, CEO of Blockstream, and Peter Todd, a Bitcoin Core contributor, expressed skepticism. They argue that current quantum technology is not yet capable of threatening Bitcoin's security and that the threat may be distant rather than immediate.

This debate underscores the evolving challenges blockchain networks face with advances in technology.
