Blockchains offer transparency but lack privacy. Zero-Knowledge Proofs (ZKPs) emerge as a game-changer, allowing users to prove they meet certain conditions (e.g., sufficient funds for a transaction) without revealing the underlying information. This enables privacy-preserving transactions, faster scalability, and regulatory compliance on blockchains. ZKPs are already being used in cryptocurrencies like Zcash and have the potential to revolutionize the future of blockchain applications.
