BAC-L2-TIA-106Celestia and modular blockchains
Full nodes and bridge nodes
The nodes that store and serve the data light nodes sample — and without which sampling has nothing to sample.
- Level
- L2 — Appchain developer
- Duration
- 3 h
- Maintainer
- Modular Blockchain / Celestia Architect
Learning objectives
- 01Distinguish the roles of the different node types
- 02Deploy a node that serves data to the network
- 03Size storage and bandwidth
Guided lab
Deploy a full node and verify it answers sampling requests.
Independent lab
Size the infrastructure for a node serving a regional developer community.
Security angle
If nobody stores, sampling succeeds and then the data vanishes: retention is an explicit role.
Assessment
Operational node plus a costed sizing note.
