Zero-knowledge proofs (ZKPs) are cryptographic methods that allow one party (the prover) to demonstrate knowledge of certain information to another party (the verifier) without revealing the actual data. This powerful technology ensures privacy and security in digital interactions. ZKPs are widely used in blockchain, authentication, and financial systems, enabling trust without exposure of sensitive details. For example, a user can prove they know a password or have sufficient funds without disclosing the actual password or account balance. By minimizing data leakage, ZKPs strengthen confidentiality, reduce fraud risks, and are becoming a cornerstone of modern digital security and decentralized applications.
