Vitalik: An open decentralized protocol is needed to transfer assets between L2

Odaily News Vitalik Buterin said in a reply to netizens on the X platform that we need an open decentralized (no operator, no management) protocol for quickly transferring assets from one L2 to another L2, and integrating it into the default sending interface of the wallet. But we need to do the basic work first. The biggest user experience problem at present is that L2 projects do not feel "like a unified Ethereum" enough. It is much better than a year ago, but there is still a long way to go before perfection. A simple algorithm: What feels easy on L1 but is difficult to do on L2? Find out the cross-L2 standards/infrastructure. For example: * Token transfer; * ENS; * Key changes in smart contract wallets (individuals and organizations). The above algorithm also applies to security/decentralization. What is good on L1 but far behind on L2? For example: * Light client (if you have an L1 light client, you can prove the L2 state); * Basic reliability (the chain will not stop or have a strange reversal: Ethereum has only had one serious problem in its 9-year history); * Proof system (we need more first-phase rollups).
