Vitalik discusses the positioning of Ethereum, Rollup scalability, centralized sequencers, and future roadmap

PANews reported on February 19th that, according to Vitalik Buterin's response on warpcast, he believes that Ethereum is both a Bitcoin-style decentralized currency and can also become a "world computer," emphasizing that decentralization and censorship resistance are the core of Ethereum's long-term value. Regarding the Rollup route, Vitalik said that the current ETH exchange 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 "everything is on L2" could weaken ETH's position as a store of value and medium of exchange, while also struggling to cope with the need for cross-L2 operations. Vitalik believes that the centralized sequencer has advantages such as preventing front-running, providing instant confirmation, and reducing the difficulty of on-chain applications, but still faces censorship resistance and Decentralization issues. Therefore, he supports solutions based on Forced Inclusion and ZK/Optimistic mechanisms to balance efficiency and Decentralization. Regarding Ether 3.0, Vitalik clarified that there is currently no concept of ETH 3.0, but the optimization of L1 (increasing Gas Limit, Stateless Verification, enhancing cross-L2 interoperability, and Blob extension) is still in progress. He pointed out that the issue of L2 paying insufficient fees for L1 transactions should not be viewed in the short term, and it is expected that with the Blob target increasing from 3 to 128, the annual L2 contribution to L1 fees could reach 256,000 ETH.
