Vitalik Buterin Discusses Advantages And Risks Of Centralized Sequencers

According to Odaily, Ethereum co-founder Vitalik Buterin has highlighted several advantages of centralized sequencers in blockchain technology. He noted that centralized sequencers can prevent issues like frontrunning, offer instant preconfirmations, and facilitate the transition of traditional applications to blockchain by converting servers into sequencers. Buterin emphasized that while centralized sequencers have benefits, they also pose risks. To mitigate these risks, blockchain's decentralized features can be employed. Mechanisms like forced inclusion can prevent sequencers from censoring users, and optimistic or zk-proof systems can ensure sequencers do not alter or violate application rules, such as inflating a token or NFT collection. Despite the potential of centralized sequencers, Buterin cautioned against relying solely on them to address issues. He advocated for a dual approach that includes both centralized sequencers and the capability to conduct transactions directly on Layer 1 or through based rollups. This approach allows for the evaluation of which method is more suitable for different applications. Buterin also stressed the importance of maintaining the ability for ordinary users to send censorship-resistant transactions, underscoring its critical role in the blockchain ecosystem.
