Question 1

What is Espresso?

Accepted Answer

Espresso is a network built to support rollups and other Layer 2 systems by providing shared infrastructure they can rely on for ordering transactions and confirming outcomes. Its goal is to let multiple rollups use the same neutral layer for sequencing and confirmations instead of each rollup running its own isolated setup.

At a high level, Espresso works as a separate network that rollups can connect to. Rollups send information to Espresso so it can:
- **Order transactions** in a way that rollups can use to build blocks deterministically.
- **Confirm and finalise ordering** using a proof-of-stake consensus mechanism so rollups can treat the result as reliable.
- **Help rollups publish or reference data** needed for verification, depending on the integration model.

This separation is intended to reduce duplicated effort across rollups and provide a single place where ordering and confirmations can be coordinated.
