BAC-L4-ARCH-107Blockchain architecture
Zero-knowledge systems within an architecture
What cryptographic proofs bring to an architecture — confidentiality, verification compression — and their real implementation cost.

- Chief Blockchain Architect
Learning objectives
- 01Distinguish validity proofs from confidentiality proofs
- 02Identify use cases where proving is genuinely justified
- 03Assess generation and verification cost
Guided lab
Verify a supplied proof and measure generation and verification costs.
Independent lab
Determine whether a verifiable-identity use case justifies a proof, with figures.
Security angle
A badly parameterised proof protects nothing: setup assumptions are part of the security model.
Assessment
Feasibility note, assessed on the honesty of its costing.
