Vitalik: L2 cross-chain needs to achieve L1 level anti-censorship, trustlessness, and no intermediary characteristics.

In a ChainCatcher message, Ethereum co-founder Vitalik Buterin responded to Paradigm CTO Georgios Konstantopoulos's statement on the X platform that "cross-chain interoperability has been resolved at the infrastructure level," stating that it can only be considered "truly resolved" when cross-L2 operations can match L1 native ETH transfers in terms of censorship resistance, trustlessness, and the absence of intermediaries. Vitalik referred to this as the "no-regression principle," emphasizing that the new system must retain the core attributes of the original system; otherwise, it cannot be considered sufficiently complete.
