Solana’s Yakovenko Challenges Ethereum L2 Security Model in Public Debate

Solana co-founder Anatoly Yakovenko has questioned the security of Ethereum Layer 2 networks, arguing that multisig dependencies undermine decentralization. His critique, posted on X on October 26, 2025, highlights risks similar to those in cross-chain bridges. Ethereum co-founder Vitalik Buterin responded by affirming L2s benefit from base-layer protection against invalid blocks. The debate centers on whether current L2 designs meet core blockchain security and decentralization standards.
