Due to the features of establishing trust and protecting privacy, succinct non-interactive zero-knowledge proofs are not only widely used in typical cryptography such as public key encryption and signature, but also highly consistent with the needs of trust and privacy in new technology fields such as blockchain and privacy-preserving computation, and is one of the current research hotspots.

The article entitled “An Overview on Succinct Non-Interactive Zero-Knowledge Proofs”, published in Journal of Cryptologic Research in 2022, is a great overview of this research direction. Firstly, this article classifies the existing succinct non-interactive zero-knowledge proofs from the perspectives of information-theoretical proofs and underlying key technologies. Secondly, this article describes the high-level ideas, protocol processes, implementation principles, performance, security and applicable scenarios of each type of succinct non-interactive zero-knowledge proofs in detail. Thirdly, this article summarizes the general construction method and performance evaluation criterion of succinct non-interactive zero-knowledge proofs. Finally, this article points out the current research hotspots and future directions in this field. The article is rich and accurate in content, clear and complete in structure. The literature is well cited, and the charts are well expressed.

It should be pointed out that there are many kinds of succinct non-interactive zero-knowledge proofs currently, with different underlying techniques and performance focus. To an extent there exist some technical barriers. In addition, there are few overviews on this field at home and abroad, lacking a systematic summary. Therefore, the application of succinct non-interactive zero-knowledge proofs has been difficult. It is believed that this overview could provide valuable guides for researchers and technical developers in the fields of zero-knowledge proofs, blockchain, and privacy-preserving computation.
