💡 Web3 Dictionary: SEQUENCERS AS A SERVICE (Sequencer as a Service, Saas) 📦⚡
What is it?
Sequencers as a Service (SaaS) is a model where external, decentralized providers offer Sequencer services for various Layer 2 (L2) solutions, such as rollups or modular blockchains.
Simply put, a Sequencer is a node that collects, organizes, and groups L2 transactions into a single batch, and then sends this batch to the base chain (L1) for finalization. Saas allows a new L2 not to build its own often centralized Sequencer, but to rent it as a decentralized service.
