BAC-L3-TIA-119Celestia and modular blockchains
Connecting a sovereign rollup to the wider ecosystem
A sovereign rollup has no settlement contract to act as its bridge: its connection to the outside world must be designed from scratch.

Learning objectives
- 01Identify the connection options open to a sovereign rollup
- 02Design a light-client-backed bridge
- 03State the trust assumptions of the chosen solution
Guided lab
Design and document your rollup's bridge to an existing chain.
Independent lab
Compare three connection options and justify the chosen one with a risk analysis.
Security angle
The bridge concentrates the whole structure's risk: bridge review is distinct from rollup review.
Assessment
Bridge design peer-reviewed against explicit trust criteria.
