With the use of zero-knowledge proof technologies, a group may show its knowledge by sending only a portion of the information—rather than the entire thing—to another group that already possesses it. zk-Snark and zk-Stark are similar in that they both use distinct mathematical formulae to solve the problem of zero-knowledge. But, Snarks and Starks also have major differences.
Similarities and Differences Between zk-SNARK & zk-STARK
Actually, the zk-STARKs and zk-SNARKs are acronyms for these technologies’ functionalities. Other notions are the reason why these two technologies vary from one another as different solutions.
Succinct is defined as “short and concise.” In other words, it stands for demonstrating if anything can be known from a portion of the data rather than the entire data set. For example, instead of creating a complete pattern, three strings are created using the pattern.
The term “non-interactive” denotes the absence of a necessity for ongoing questioning on the part of those who verify the veracity of zero-knowledge proofs. The verifier assumes that the prover has the information without needing to clarify, and there is no interaction between them as soon as the prover enters the required strings in the three boxes.
The Origins of zk-SNARK
The University of California professor Alessandro Chiesa co-authored a paper in which the name “zk-SNARK” was first used to refer to the zkp (zero-knowledge proofs) they created.
Elliptic curves provide the basis of a Snark’s security. It is a fundamental tenet of elliptic curves used in cryptography that it is impossible to determine the discrete logarithm of an elliptic curve element with respect to a chosen point. Snarks are built on this presumption.
Zk-SNARK is used by significant blockchains, including zCash, Aleo, Mina, and Aztec. Each chain uses the zk-SNARK technology in a unique way.
