BAC-L2-TIA-105Celestia and modular blockchains
Running a light node
The node you can run on a modest laptop that genuinely contributes to the network's security.
- Level
- L2 — Appchain developer
- Duration
- 3 h
- Maintainer
- Modular Blockchain / Celestia Architect
Learning objectives
- 01Launch a light node and sync it
- 02Verify that it is actually sampling
- 03Measure its real bandwidth consumption
Guided lab
Start a light node on a test network and watch its successive samplings.
Independent lab
Measure data consumption over twenty-four hours and assess the real cost in a Cameroonian context.
Security angle
A light node verifies availability, not validity: keep those two guarantees distinct.
Assessment
Running light node plus an annotated consumption record.
