PANews reported on February 19 that according to Vitalik Buterin’s response on warpcast, he believes that Ethereum is both a decentralized currency like Bitcoin and can become a “world computer”, and emphasized that decentralization and anti-censorship capabilities are the core of Ethereum’s long-term value.

Regarding the Rollup expansion route, Vitalik said that Ethereum currently adopts the L1+L2 hybrid model, but it still needs to define which transactions are suitable for L1 and which are suitable for L2. He warned that "putting everything on L2" may weaken ETH's value storage and transaction medium status, and it will also be difficult to cope with the needs of cross-L2 operations.

Regarding the centralized sequencer, Vitalik believes that it has advantages such as preventing preemption, providing instant confirmation and reducing the difficulty of application on-chain, but there are still problems of anti-censorship and decentralization. Therefore, he supports solutions based on forced inclusion and ZK/Optimistic mechanisms to balance efficiency and decentralization.

Regarding Ethereum 3.0, Vitalik clarified that there is no concept of ETH 3.0 at present, but the optimization of L1 (increasing Gas Limit, Stateless Verification, enhancing cross-L2 interoperability and Blob expansion) is still in progress. He pointed out that the problem of insufficient L2 payment of L1 transaction fees should not be viewed in the short term, and it is expected that as the Blob target is increased from 3 to 128, the L1 fee contributed by L2 may reach 256,000 ETH per year.
