Espresso's shared sequencer provides a novel approach to transaction ordering and sequencing, offering a potential alternative to native Layer 2 (L2) sequencing. In L2s, sequencers play a critical role in deciding the order of transactions, and this power can sometimes lead to centralization risks. Espresso's shared sequencer aims to decentralize this responsibility, allowing for more equitable transaction ordering across multiple chains. The approach could reduce MEV extraction and improve fairness in transaction processing. However, the effectiveness of this model will depend on whether it can scale efficiently, avoid bottlenecks, and maintain low latency. It also needs to integrate well with existing L2 infrastructure. If successful, Espresso’s shared sequencer could be an appealing option for developers looking for a more decentralized sequencing solution.
