# Spartan: High-speed zkSNARKs without trusted setup
|
|
|
|
|
|
|
|
Spartan is a research project to design high-speed zero-knowledge proof systems, a cryptographic protocol that enables a prover to prove a mathematical statement (e.g., that a given program was executed correctly) without revealing anything besides the validity of the statement.
|
|
|
|
The current repository includes a library that implements
|
|
a zero-knowledge succinct non-interactive arguments of knowledge (zkSNARKs), a type of zero-knowledge proof system with short proofs and verification times. Unlike many other zkSNARKs, Spartan does not require a trusted setup and its security relies on the hardness of computing discrete logarithms (a well-studied assumption). The scheme is described in our [paper](https://eprint.iacr.org/2019/550).
