Odaily Planet Daily News Vitalik Buterin replied to netizens on X: "For many years, I have been talking about the need for (L1 and L2) lightweight clients. I think the solution will come when @NoahCitron Helios (or an alternative) makes a convenient javascript library to handle these things that wallets can easily import. In addition, it is important that the L2 configuration (config) is transferred to the chain, because this will make it easier for lightweight client state proof verification functions to become part of the configuration, making universal L2 lightweight clients possible.
