Vitalik: L2 cross-chain needs to achieve L1 level censorship resistance, trustlessness, and no intermediaries

ChainCatcher message, Ethereum co-founder Vitalik Buterin responded to Paradigm CTO Georgios Konstantopoulos's point on the X platform that "cross-chain interoperability has been solved at the infrastructure level," stating that it is only considered "truly solved" when cross-L2 operations can match the censorship resistance, trustlessness, and non-intermediary nature of native ETH transfers on L1.

Vitalik referred to this as the "no-regression principle," emphasizing that new systems must retain the core attributes of the original system; otherwise, they cannot be regarded as sufficiently complete.
