Preface

Any idea why I am so much hooked up to Blockchain?

Weird but true, the Universe itself is decentralized in nature and

pretty messed up. There is no single master, no single force, and no

particular nation that can be termed as the most powerful.

The beauty of any emerging technology lies in the fact that nobody is

an expert here. The space is ever changing and evolving manifolds

over the passing years. Even the very mysterious, all-wise father of

Blockchain, Satoshi Nakamoto, has to stay relevant in the market

through regular learning. There was a time when the compact 109

pager “Blockchain from concept to execution” remained a sweetheart

among the Blockchain lovers. Now, the time has come for a fresh

start, and it starts 100 steps ahead from where it ended in the last

version.

Today, the Blockchain comes with many variations, including shared

ledger, distributed ledger, mutable ledger etc. In addition to that,

there are adjoining technologies as the layer-2 set up and low code

environments for smart contracts. Knowing them all and matching to

the individual’s requirement is a must for the future IT industry.

This new version is thoughtfully designed to match the need of the

students and experts alike.

Phase I covers the most widely adopted Blockchains of today. The

first chapter starts from the very basic concepts of Blockchain that

everyone should learn. The remaining chapters of this phase discuss

some of the most popular Blockchains of today.

Phase II further looks over the popular public inter-operable

Blockchains in the market. It also explores the competitive study

between the different public Blockchains and inter-operable

Blockchains.

Phase III illustrates the private permissioned DLTs that are adopted

by the organizations. The final chapter in this phase also comes with

a comparative study to help the reader choose one over the other.
