You've completed the Zero-Knowledge Proofs module! Let's review what you've learned.
Zero-Knowledge Concept
Prove knowledge of information without revealing the information itself. Privacy + verification together.
Three Properties
Completeness (true → provable), Soundness (false → not provable), Zero-Knowledge (no leaks).
Ali Baba's Cave
Demonstrates interactive ZK: probability of cheating = 0.5^rounds. After many rounds, confidence approaches 100%.
ZK-SNARKs
Tiny proofs (~200 bytes), fast verification. Trade-off: requires trusted setup, not quantum-safe. Used by Zcash, zkSync.
ZK-STARKs
Transparent (no setup), quantum-resistant. Trade-off: larger proofs (50-200KB), slower. Used by StarkNet.
Bulletproofs
No trusted setup, logarithmic size. Great for range proofs (confidential amounts). Used by Monero.
