BAC-L2-TIA-109Celestia and modular blockchains
Rollup architectures
A structured survey of rollups: where computation runs, where disputes settle, where data lives, and who decides the valid chain.
- Level
- L2 — Appchain developer
- Duration
- 3 h
- Maintainer
- Modular Blockchain / Celestia Architect
Learning objectives
- 01Classify a rollup along its four functions
- 02Compare sovereign and settled rollups
- 03Identify who holds fork-choice authority in each case
Guided lab
Classify five production rollups against the four-function grid.
Independent lab
Choose and justify a rollup architecture for a Cameroonian public service.
Security angle
Who can censor, who can freeze, who can exit: three questions to ask of any rollup architecture.
Assessment
Architecture note, assessed on the coherence between constraints and choices.
