Vitalik talks about Ethereum positioning, Rollup capacity expansion, centralized sequencer and future roadmap

PANews February 19th news, 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", and emphasizes that decentralization and censorship resistance are Ethereum The core of 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 ones are suitable for L2. He warned that "everything is put in L2" may weaken ETH's store of value and trading medium status, while also having difficulty coping with the demand for cross-L2 operations.

Regarding the centralized sequencer, Vitalik believes that it has the advantages of preventing rush, providing instant confirmation, and reducing the difficulty of applying the link, 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 currently no ETH 3.0 concept, but L1 optimization (improving Gas Limit, Stateless Verification, enhancing cross-L2 interoperability and Blob expansion) is still advancing. He pointed out that the problem of insufficient L1 transaction fees for L2 paying L1 should not be viewed in the short term, and it is expected that as the Blob target increases from 3 to 128, the L1 fee contributed by L2 may reach 256,000 ETH per year.
