A review paper on architecture of blockchain

Decentralization, persistency, anonymity, and auditability are just a few of the advantages of blockchain. Blockchain applications include a broad range of topics, including cryptocurrencies, financial services, risk management, internet of things (IoT), and public and social services. Although a number of studies have focused on the use of blockchain technology in different application areas, there is yet to be a thorough assessment of the technology from both a technical and an application standpoint. To close this gap, we conducted a thorough blockchain technology study. Other than Bitcoin, blockchain may be utilized in a variety of applications. Blockchain has shown its capacity to disrupt traditional sectors because to its basic characteristics of decentralization, persistency, anonymity, and auditability. This article provides a comprehensive overview of the blockchain. This article, in particular, explains the blockchain taxonomy, analyzes common blockchain consensus algorithms, evaluates blockchain applications, and discusses technical difficulties as well as recent advancements in addressing the issues. Furthermore, this article discusses the future paths of blockchain technology.
