The first time I encountered the Zero-Knowledge Proofs concept, I was amazed by the way of how something can be proved without disclosing the information behind it.

In brief, one party (prover) proves another party (verifier) the truth of some statement without disclosing any secret information.

For instance, a person could prove he is over the age limit without disclosing his entire date of birth in case if it is implemented within the system in such a manner. Mathematics in cryptography allows performing this action.

The proof is checked, while the confidential information is not disclosed.There have been applications of Zero-Knowledge Proofs in the blockchain world too.

Some implementations apply Zero-Knowledge Proofs to prove computations or transactions while restricting the disclosure of data.

Thereby, they enhance privacy as well as help some networks increase efficiency under certain circumstances. Nonetheless, the above-described technology cannot be considered miraculous.

The generation and verification of the proofs may be a computationally intensive process and errors made during their implementation may cause security vulnerabilities.

The proof proves only what it was meant to prove and not everything becomes true automatically because of a proof.

Nevertheless, the most valuable feature lies in finding an optimal balance between proving and hiding.
