zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is a type of zero-knowledge proof that allows one party (the prover) to prove to another party (the verifier) that a statement is true, without revealing any information about the statement itself.
zk-SNARKs are used in a variety of applications, including privacy-preserving cryptocurrencies such as Zcash, and secure multi-party computation protocols. They are particularly useful in situations where it is important to verify the authenticity of a statement without revealing any sensitive information about the statement itself.
In a zk-SNARK proof, the prover generates a proof that a statement is true, and the verifier can check the validity of the proof without needing to know the specifics of the statement. The proof consists of a small amount of data (called a "proof") that can be easily verified by the verifier, but is infeasible to generate without knowing the specifics of the statement. This allows the prover to prove the authenticity of a statement without revealing any sensitive information about the statement.
zk-SNARKs are based on a branch of mathematics called elliptic curve cryptography, and they rely on advanced mathematical concepts such as polynomial commitments and homomorphic hashes. Despite their complexity, zk-SNARKs have gained widespread adoption due to their efficiency and versatility.
There are several popular libraries for implementing zk-SNARKs in the Rust programming language. Some of the most well-known libraries include:
bellman: This library provides a Rust implementation of the Bellman zk-SNARK library, which is a high-performance library for generating and verifying zk-SNARK proofs.
snarky: This library is a Rust implementation of the libsnark library, which is a C++ library for generating and verifying zk-SNARK proofs. snarky provides a Rust-friendly interface to libsnark and is designed to be easy to use.
jubjub: This library is a Rust implementation of the jubjub curve, which is a curve used in the construction of zk-SNARKs. It provides efficient algorithms for working with jubjub points and scalars, and is used by other libraries as a building block for implementing zk-SNARKs.
zokrates: This is a toolkit for implementing zk-SNARKs and other zero-knowledge protocols in the Rust programming language. It provides a high-level interface for working with zk-SNARKs and makes it easy to write custom zero-knowledge proofs.
These are just a few examples of the libraries available for implementing zk-SNARKs in Rust. There are many other options available, and the choice of library will depend on the specific needs and requirements of your application.
There are several popular libraries for implementing zk-SNARKs in the Go programming language. Some of the most well-known libraries include:
