Paradigm CTO states that the issue of cross-chain interoperability has been resolved, but Vitalik emphasizes that the "no degradation principle" still needs to be met.

Wu Shuo learned that Paradigm CTO Georgios Konstantopoulos posted on X stating that cross-chain interoperability at the infrastructure layer has been resolved. The core issues lie in: excellent integration at the wallet layer; excellent arbitrage at large scale; and low latency at large scale. He believes issue 1 is a front-end technology problem, while issues 2 and 3 are market-making technology problems. Ethereum founder Vitalik Buterin replied that cross-chain interoperability must achieve the same censorship resistance, trustlessness, and intermediary-free characteristics as intra-L2 operations, adhering to the "no degradation principle," meaning the new mechanism must retain the core properties of $ETH transfers on L1.
