BAC-L4-ARCH-103Blockchain architecture
Choosing an execution model
Contracts on a shared chain, an application chain, a sovereign rollup: three answers to one need, with three cost and control profiles.
- Level
- L4 — Blockchain architect
- Duration
- 3 h
- Maintainer
- Chief Blockchain Architect
Learning objectives
- 01Compare the models on cost, control and time to service
- 02Identify the threshold at which a dedicated chain is justified
- 03Plan the migration trajectory between models
Guided lab
Cost all three models for the same use case and find the tipping point.
Independent lab
Design the migration trajectory from a contract to a dedicated chain.
Security angle
Each model shifts security: from application to protocol, or the reverse. Say so explicitly.
Assessment
Costed study with an identified, justified tipping point.
