BLOCKCHAIN TECHNOLOGIES IN E-SERVICES

Abstract

Blockchain (or blockchain) is a distributed database consisting of blocks of information that are interconnected using cryptographic hashes. Each block contains a set of transactions or other data, as well as a hash of the previous block. Thus, the blocks form a chain where each block contains information about the previous block. One of the main features of the blockchain is its decentralization. Blockchain works on the basis of consensus, which means that network participants must reach agreement on changes to the database. This allows network participants to have a common version of the database and ensures transparency and reliability of data storage and transmission.
