Banafa Ahmed. Introduction to Blockchain Technology

River Publishers, 2023. — 53 p. — ISBN: 978-87-7022-160-3.This book explores the fundamentals and applications of Blockchain technology. Readers will learn about the decentralized peer-to-peer network, distributed ledger, and the trust model that defines Blockchain technology. They will also be introduced to the basic components of Blockchain (transaction, block, block header, and the chain), its operations (hashing, verification, validation, and consensus model), underlying algorithms, and essentials of trust (hard fork and soft fork). Private and public Blockchain networks similar to Bitcoin and Ethereum will be introduced, as will concepts of Smart Contracts, Proof of Work, and Proof of Stack.Blockchain is an emerging technology that can radically improve transaction security in banking, supply chain, and other transaction networks. It’s estimated that Blockchain will generate $3.1 trillion in new business value by 2030. Essentially, it provides the basis for a dynamic distributed ledger that can be applied to save time when recording transactions between parties, remove costs associated with intermediaries, and reduce risks of fraud and tampering.The classical definition of Blockchain is that it is “a distributed database existing on multiple computers at the same time. It constantly grows as new sets of recordings, or ‘blocks’, are added to it. Each block contains a timestamp and a link to the previous block, so they form a chain”, but the best definition of Blockchain according to MIT is cryptography + human logic. If the internet is all about providing connectivity, Blockchain is all about enabling trust.This book is for everyone who would like to have a good understanding of Blockchain Technology and its applications and its relationship with business operations including C-Suite executives, IT managers, marketing and salespeople, lawyers, product and project managers, business specialists, and students. It’s not for programmers who are looking for codes or exercises on the different platforms of Blockchain.What is Blockchain?
