Why Decentralized Sequencers?
Centralization is antithetical to crypto. And yet, today’s rollups almost universally depend on a single sequencer. Centralized sequencers provide fast transaction confirmations and reduce costs by batching and compressing transactions. However, these benefits come at the cost of relying on a single trusted actor for liveness and censorship resistance.
Sacrificing decentralization for an improved user experience is an unacceptable Faustian bargain.
Astria tackles centralization head-on, providing rollups with a decentralized sequencer and even better UX. Astria’s shared sequencer network is a middleware blockchain with its own decentralized sequencer set which accepts transactions from multiple rollups. These transactions are ordered into a single block and written to the base layer without executing them.
