# 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.
