BAC-L4-XCHAIN-111Interoperable systems engineering
Asset representation across ecosystems
An asset that crosses three chains is no longer the same asset. Tracking its identity, fungibility and risk at every hop.
- Level
- L4 — Blockchain architect
- Duration
- 3 h
- Maintainer
- Chief Blockchain Architect
Learning objectives
- 01Track an asset's identity across several hops
- 02Identify breaks in fungibility
- 03Design an asset acceptance policy for an application
Guided lab
Move an asset across three chains and document its representation at each step.
Independent lab
Write the asset acceptance policy for a cross-border payment application.
Security angle
Accepting a bridged asset means accepting the bridge's risk: the acceptance policy is a security decision.

Acceptance policy assessed on how it handles bridge risk.
