Abstract :
The paper analyzes the privacy preserving problem for distributed ledgers. It
provides an overview of technologies such as mixers, zero-knowledge proof algorithms, homo-
morphic encryption, secure multi-party computation, anonymous signatures, and hardware
solutions. Advantages and disadvantages of each technology are identified, as well as usage
samples in the existing distributed ledgers. As a result, unsolved problems and prospects for
further research are formulated.
