8.1 Introduction

Blockchain initially came into view with the concept of bitcoin (also known as Cryptocurrency) [1–3]. People nowadays consider blockchain as the “Topic of Interest,” as it is immutable and transparent between stakeholders and trusted parties. The introduction of blockchain has inspired a transfer from centralized to decentralized dynamic architecture. Blockchain's decentralized architecture is used by several distributed nodes and each of these nodes contain some cryptographically‐chained transaction records. These transactions are set up in blocks and agree upon some of the common consensus protocols. Because of the chaining of blocks with the distributed protocol, the immutability of the blockchain is ensured. The transparency and immutability make blockchain desirable. Any user can verify the history of the bitcoin transaction and any tampering with it. The work finally states that once the data is added to the chain it cannot be modified. The three main characteristics (transparency, decentralization, and genuine ability) make it a publicly verifiable architecture. Many applications have been planned for blockchain, and many financial experts and scientists are expecting ...
