I am not sure the last time I heard so much of a discussion about a technology across governments, organizations, communities, and individuals. Blockchain is a technology that is being discussed and debated at length across the world and organizations, and without a reason. Blockchain is not just a technology that has limited effect on our life. It has and will have widespread ramifications in our lives. The day is not far when blockchain will touch almost each aspect of our activities—whether paying bills, transactions with any organizations, getting salary, identity, educational results, activities, and so on. This is just the beginning, and we have just started to understand the meaning of decentralization and its impact.

I have been working on blockchain for quite some time now and have been a crypto-investor for long. I am a technologist and am completely fascinated by Bitcoin because of the architectural marvel it is. I have never come across such superior thought process and architecture that actually solves not only economic and social problems but solves some technically unsolved problems such as Byzantine general problems and fault tolerance. It solves the problem of distributed computing at large.

Ethereum is built in an almost similar fashion, and I was in awe when I first heard and experienced smart contracts. Smart contracts are one of the greatest innovation to deploy decentralized applications on blockchain and extend it easily with custom logic, policies, and rules.

I have thoroughly enjoyed authoring this book and sincerely hope that you would also enjoy reading and implementing Solidity. I have brought in a lot of my Solidity experience and try to make the maximum out of it. I hope this book makes you a better Solidity developer and a superior programmer.

Do let me know if there is anything I can do to make your experience better with this book. I am all ears, and happy learning!
