The executor is a service responsible for subscribing to block commitments posted to the L1 contract, applying
transactions to the rollup state, and submitting
[mock proofs](https://github.com/EspressoSystems/espresso-sequencer/blob/main/example-l2/src/prover.rs) to the rollup

contract. Rollups often separate the roles of executor and prover into two distinct services, but this example combines
them for the sake of simplicity.

The rollup API is a REST API that includes a `submit` and `query` endpoint. With the containerized example rollup
running, visit http://localhost:8082/ for API documentation.

The rollup contract stores the most recent rollup state commitment. The contract updates the state commitment when it
receives a valid state transition proof from the executor.
