What is zk-SNARK and how does it work?

zk-SNARK stands for Zero-Knowledge Succinct Non-Interactive Argument of Knowledge. It is a type of proof construction that allows one party to prove to another party that a given statement is true, without revealing any additional information apart from the statement’s validity. In other words, it enables one party to prove to another that they know a piece of information, without actually revealing the information to the other party.

zk-SNARKs make use of mathematical functions known as elliptic curves to generate the proof of knowledge. The elliptic curve functions are a type of encryption that allows information to be transferred in an encrypted form so that it can only be accessed by the parties involved. The use of these mathematical functions enables zk-SNARKs to achieve a high level of security and privacy.

One of the main applications of zk-SNARKs is in the field of cryptocurrency. It allows for anonymous transactions, as the proof of knowledge can be used to verify the validity of a transaction without revealing the identity of the parties involved. This has led to the development of privacy-focused cryptocurrencies such as Zcash and Monero.

Another potential application of zk-SNARKs is in the field of voting. It could be used to verify the validity of a vote without revealing the identity of the voter, ensuring a high level of privacy and security in the voting process.

History and development of zk-SNARK

The concept of zk-SNARK was first introduced in 2013 by researchers at Massachusetts Institute of Technology (MIT), Johns Hopkins University, and Tel Aviv University.
