Blockchain Technology Overview: Architecture, Proposed and Future Trends

Abstract

Blockchain is a decentralized, distributed database that eliminates the need for a reliable middleman, enabling safe and transparent transactions among participants. This technology is rapidly emerging and has revolutionized both financial and non-financial transaction systems, becoming ubiquitous. Its benefits are now compelling banks, industries, and countries to integrate it into their financial, industrial, and government sectors. Initially, it effectively addressed the issues of centralization and double-spending. The article covers the fundamental building blocks of blockchain technology (BT), including the cryptographic techniques used to secure data, the network&s;s consensus mechanism, and smart contract functionality that automates transaction execution. Additionally, the article investigates suggested options for improving BT, such as scalability solutions and privacy-improving technologies. Finally, the study concludes by examining potential future developments in the field, such as decentralized finance, the fusion of artificial intelligence and machine learning, and the introduction of new applications.
