Solana Co-Founder Warns Ethereum L2s Remain Vulnerable to Quantum Attacks

Solana Labs co-founder Anatoly Yakovenko has highlighted the vulnerability of Ethereum Layer 2 (L2) solutions to quantum attacks. According to Yakovenko, these L2s are not yet quantum safe due to their reliance on cryptographic primitives that are susceptible to quantum computing.

The issue arises from the use of Elliptic Curve Digital Signature Algorithm (ECDSA) signatures and public keys being revealed on-chain during transactions. This creates a potential 'harvest now, decrypt later' risk, where future quantum computers could derive private keys and enable fund theft.

In contrast, Solana has made significant progress in post-quantum cryptography with its Falcon-512 verification suite already deployed in production environments such as Anza and Firedancer clients. The network is expected to continue phasing out vulnerable cryptographic primitives in favor of quantum-safe alternatives.
