WHY DECENTRALIZE SEQUENCERS?

Summary from the TLDR Crypto newsletter

In this article, Ethereum infrastructure company Astria emphasizes the need for decentralized sequencers in rollup protocols over the centralized ones used currently. Although centralized sequencers offer faster transaction validations, they pose risks such as potential invalid commitments and manipulation for the operators' own benefit. To counter this, Astria suggests either a simple leader rotation mechanism or a Byzantine Fault Tolerant consensus algorithm for rollup decentralization, bringing more security and redundancy while avoiding single-party dependency.
