Shrnutí	A zero-knowledge proof is a cryptographic protocol in which a prover can convince a verifier that a statement is true without revealing any additional information beyond the truth of the statement. Introduced by Goldwasser, Micali, and Rackoff in 1985, zero-knowledge proofs have profound applications in authentication, privacy-preserving verification, and blockchain systems.	A digital signature scheme provides authentication, integrity assurance, and non-repudiation of electronically signed documents. Using public-key cryptography (such as RSA, DSA, or ECDSA), the originator signs a message with a private key in a way that any recipient can verify the signature using the originator's public key, proving that the message was created by the claimed author and has not been tampered with.
