### **Transaction Submission**

Conla sequencers collect transactions from users and order them into rollup blocks.

### **Transactions Posted to DA Layer**

Conla sequencers continuously publish transactions to the DA layer without waiting for proofs. They receive a portion of gas fees (and MEV) as a reward.

### **Compute State Transition**

Conla full nodes read the DA layer for new transactions and execute the changes to the rollup's state. This provides transaction finality quickly to users.

### **Proof Generation**

Conla verifier monitor the DA layer for transactions. They compete against each other to generate a proof that verifies the rollup's new state and receive a portion of gas fees as a reward.

### **Proof Submission & Verification**

Conla verifier submits a rollup transaction that contains the proof as an argument to TON, which verifies the proof.
