Answer: True
ZK-proofs enable one party to prove knowledge of a secret (e.g., valid transaction) without revealing the secret itself. Applications: privacy-preserving cryptocurrencies (Zcash), identity verification, and confidential smart contracts. Computationally intensive but advancing with zk-SNARKs/zk-STARKs. Critical for privacy and scalability questions.
