The Trusted Sequencer reads transactions from the pool and decides whether to discard them or order and execute them. Transactions that have been executed are added to a transaction batch, and the Sequencer's local L2 State is updated.
Once a transaction is added to the L2 State, it is broadcast to all other ZK Chain nodes via a broadcast service. It is worth noting that by relying on the Trusted Sequencer, we can achieve fast transaction finality (faster than in L1). However, the resulting L2 State will be in a trusted state until the batch is committed in the Consensus Contract.
