Solana co-founder Anatoly Yakovenko warned that Ethereum Layer 2 networks are not secure against future quantum computing threats due to their reliance on current cryptographic methods like ECDSA. He highlighted risks such as "harvest now, decrypt later," where attackers could collect encrypted data now and decrypt it once quantum computers advance. Solana is proactively integrating post-quantum cryptography, while other blockchains like Ethereum, Cardano, and Ripple are exploring or planning quantum-resistant solutions. This underscores the urgent need for blockchain networks to upgrade security to protect digital assets against emerging quantum threats.
