  Abstract

Recently, with the development of blockchain technology, there is a growing interest in preserving the privacy of data and transactions in the blockchain. Since the first blockchain system bitcoin was announced in 2008, the characteristic of blockchain data being public to all has drawn the attention of many people, but this is rather lowering the utilization of blockchain. Accordingly, various types of blockchain privacy-preserving protocols are being studied. Most of these protocols are being studied on the basis of zero-knowledge proof and in a way that minimizes execution time to reduce impact on blockchain systems. When privacy-preserving protocols are applied within blockchain, they can contribute to activating blockchain by providing anonymity as well as reliability and transparency which are advantages of blockchain. In 2019, a variety of privacy- preserving protocols have been presented and applied to the commercialized platform. In this paper, we will analyze the trends and performance of these protocols and describe their future research directions.
