According to CoinMeta, Vitalik emphasizes that Ethereum's long-term value comes from decentralization, privacy, and security. As the Ethereum ecosystem gradually returns to the mainnet, the acceleration of mainnet scaling and the reduction in costs have prompted ENS and others to revert to L1, increasing the operational pressure on independent L2. Synthetix adopts a hybrid architecture, with L1 for asset custody and off-chain matching to improve speed and trust. L1 and L2 will restructure the balance; L2 will not disappear. The mainnet needs to strengthen execution, liquidity, resistance to censorship, and economic security.
