BAC-L1-AVAX-101Avalanche
Avalanche architecture
A primary network that secures, application networks that build on it: the structure and what it implies for a builder.
- Level
- L1 — Blockchain developer
- Duration
- 3 h
- Track
- Avalanche
- Maintainer
- Avalanche Lead Architect
Learning objectives
- 01Describe the primary network's role and its three chains
- 02Situate an application L1 within the architecture
- 03Explain what a primary-network validator actually validates
Guided lab
Explore the test network and identify each primary-network chain on screen.
Independent lab
Write a note comparing this model with Polkadot's shared security for the same use case.
Security angle
An application L1 does not automatically inherit the primary network's security: cost out what it must produce itself.
Assessment
Comparative note, assessed on the accuracy of the security model described.
