Vitalik: L2 cross-chain needs to achieve L1-level anti-censorship, trustless and intermediary-free features

Odaily News Ethereum co-founder Vitalik Buterin responded to Paradigm CTO Georgios Konstantopoulos's view on the X platform that "cross-chain interoperability has been solved at the infrastructure level" and said that cross-L2 operations can only be considered "truly solved" when they are comparable to ETH native transfers on L1 in terms of censorship resistance, trustlessness, and the lack of intermediaries. Vitalik called this the "no-regression principle", emphasizing that the new system must retain the core properties of the original system, otherwise it cannot be considered complete enough.
