摘要
Zero-Knowledge Succinct Non-interactive ARguments of Knowledge (zkSNARKs) have been a hot topic lately because they are one of the essential tools for building privacy-preserving blockchain applications. zkSNARKs enable one party (the prover) to prove to another party (the verifier) that a statement is true, without revealing other information apart from the fact that the statement is true. They can be used to empower cryptocurrency transaction privacy, confidential smart contract, identity authentication, supplychain management, private healthcare system, etc.
The journey of investigating zkSNARKs can be traced back to when Goldwasser, Micali and Roacknoff first introduced the zero-knowledge interactive proof system, which enables a prover to convince a verifier that a statement is true, without revealing the witness [GMR89].
Since then, lots of work has been done to make zkSNARK practical. In this presentation, we are going to have an overview of arithmetization, zkSNARK protocol design and implementation.
