Project Context Primer

This book focuses on the Nomos Testing Framework. It assumes familiarity with the Nomos architecture, but for completeness, here is a short primer.

• Nomos is a modular blockchain protocol composed of validators, executors, and a data-availability (DA) subsystem.
• Validators participate in consensus and produce blocks.
• Executors are validators with the DA dispersal service enabled. They perform all validator functions plus submit blob data to the DA network.
• Data Availability (DA) ensures that blob data submitted via channel operations in transactions is published and retrievable by the network.

These roles interact tightly, which is why meaningful testing must be performed in multi-node environments that include real networking, timing, and DA interaction.
