\"What<\/figure>\n

Rollup sequencers are specialized nodes that are perhaps the most important part of a rollup system. They perform the most crucial functions of a rollup, such as processing and batching together transactions, and submitting those batches to the Ethereum mainnet. <\/p>\n

The following paragraphs offer a closer look at this important technology and its different implementations. To start off, let\u2019s briefly go over the sequencing process.<\/p>\n

Rollup sequencers 101<\/h2>\n

We can think of\u00a0 rollup sequencers as the equivalent of validators in rollup networks, but with additional specialized functions owing to the fact that they operate within a Layer 2 network. So a sequencer is responsible for picking up transactions from a Layer 2 mempool and then processing them to be in a state that is appropriate for submission to the Ethereum mainnet. That process involves verifying and ordering the transactions, then bundling them together, which allows them to be sent to Ethereum via a single transaction. Where applicable (read in ZK rollups) the sequencer also the validity proof for those transactions to Ethereum.<\/p>\n
