Problems of developing a decentralized system based on blockchain technology

Abstract

The article discusses the problems of developing distributed ledger systems, which is a new approach to creating databases, the key feature of which is the absence of a single control center. Each node compiles and writes registry updates independently of the other nodes. Unlike distributed databases, each participant in a distributed ledger system stores the entire history of changes and validates the addition of any changes to the system using a consensus algorithm, which mathematically guarantees that data cannot be forged.
