Ethereum Founder Vitalik Emphasizes True Cross-L2 Interoperability Must Match Native ETH Transfer Security

Ethereum founder Vitalik Buterin recently addressed the ongoing debate surrounding cross-chain interoperability, emphasizing that current solutions fall short of achieving true decentralization. He argued that unless cross-L2 transactions can match the censorship resistance, trustlessness, and non-intermediated nature of native Layer 1 (L1) Ethereum transfers, the interoperability challenge remains unresolved. This perspective, encapsulated in his so-called “No-Regress Principle,” underscores the necessity for new protocols to maintain the fundamental security and decentralization guarantees inherent to Ethereum’s base layer. Vitalik’s comments highlight the critical importance of preserving these core properties to ensure robust and secure multi-layer blockchain ecosystems, a key consideration for developers and investors navigating the evolving crypto infrastructure landscape.
