BAC-L3-XCHAIN-105Interoperable systems engineering
XCM lab: parachain to parachain
Second comparative lab: messaging under shared security, where transport inherits guarantees the other models must produce themselves.
- Level
- L3 — Infrastructure engineer
- Duration
- 4 h
- Maintainer
- Chief Blockchain Architect
Learning objectives
- 01Establish XCM messaging between two chains
- 02Measure latency, cost and failure rate under the same conditions
- 03Identify what shared security makes unnecessary
Guided lab
Run a hundred measured XCM transfers between two local chains.
Independent lab
Compare the XCM record with the IBC one and account for every structural difference.
Security angle
Here trust rests on the Relay Chain: the assumption is relocated, not removed.
Assessment
Comparative XCM/IBC record with an interpretation of the differences.
