Важливість блокчейн-технологій у сучасному світі

Abstract

This work is an exploration of blockchain technology as a unique type of database that allows for the addition of information but prevents editing, altering, or deletion. It highlights the structure of a blockchain as a chain of interconnected blocks, as well as the decentralized nature of the system. The text also discusses smart contracts, which are self-executing programs embedded within the blockchain, and their potential for automation, error reduction, and cost savings. Additionally, the paper addresses the challenges of scalability and energy efficiency in blockchain technology, noting various solutions such as layering, sharding, sidechains, and alternative consensus algorithms aimed at improving network performance and environmental sustainability.
