Learning objectives
- 01Deliver a tested, governed and documented sovereign chain
- 02Establish and operate a working IBC link
- 03Demonstrate a coordinated upgrade against populated state
Guided lab
Full CI pipeline: build, tests, simulation, network bring-up, IBC channel opening.
Independent lab
Have another team reproduce the chain and its IBC link from the repository alone.
Security angle
Cross-review: module authorisations, supply invariants, slashing parameters, relayer operations.
Assessment
Technical defence, reproduction by the panel, and a live IBC transfer.
