Performance Analysis of Cryptographic Hash Functions Suitable for Use in Blockchain

A blockchain, or in other words a chain of transaction blocks, is distributed database that maintains an ordered blocks reliably connect the information contained them. Copies are usually stored on multiple computers and synchronized accordance with rules building which provides secure change-resistant storage information. To build linked lists hashing used. Hashing special cryptographic primitive one-way, resistance to collisions search for prototypes computation hash value (hash message digest). In this paper comparative analysis performance algorithms can be used modern decentralized blockchain networks conducted. Specifically, different desktop systems, number cycles per byte (Cycles/byte), amount hashed second (MB/s) rate (KHash/s) investigated. The allows us choose most suitable candidates systems type blockchain.
