Solana Labs co-founder Anatoly Yakovenko has issued a stark warning regarding the quantum safety of Ethereum Layer 2 solutions (L2s). Yakovenko highlighted that these L2s, which rely on ECDSA signatures, are susceptible to quantum attacks, urging users to "abandon all hope." This comes as Solana showcases its Falcon-512 post-quantum signature verification, positioning itself as a leader in quantum-resistant blockchain technology. Ethereum L2s, including popular zkEVM rollups like Arbitrum and Optimism, remain exposed due to their reliance on cryptographic primitives vulnerable to quantum computing. The potential "harvest now, decrypt later" risk could allow future quantum computers to derive private keys, posing a significant threat to fund security. In contrast, Solana is advancing with Falcon-512 implementation, aiming for a phased rollout of quantum-safe verification across its network. As the crypto industry moves towards quantum security, Ethereum plans to achieve quantum readiness by 2029, while other major cryptocurrencies like Algorand and Cardano are also progressing in post-quantum developments. Global regulatory frameworks are pushing for quantum security adoption, with significant infrastructure changes expected by 2035.
