According to PANews, at the "10th Blockchain Global Summit" held by Wanxiang Blockchain Lab, Ethereum co-founder Vitalik Buterin gave a speech saying that Ethereum has made great improvements in L2, smart accounts, account abstraction, zero-knowledge proof applications and wallet user experience.

He said that Ethereum now looks like 34 or more different chains, and in the future it should be a unified ecosystem, achieved through chain-specific addresses and ERC-7683 (a universal cross-L2 protocol).

In terms of light clients, today Helios is a light client of L1 without L2. In the future, L2 will develop its own merkle proof function in cross-chain contracts and can be used as a general light client.
