Description

Learn Blockchain Programming with JavaScript begins by giving you a clear understanding of what blockchain technology is. You’ll then set up an environment to build your very own blockchain and you’ll add various functionalities to it. By adding functionalities to your blockchain such as the ability to mine new blocks, create transactions, and secure your blockchain through a proof-of-work you’ll gain an in-depth understanding of how blockchain technology functions. As you make your way through the chapters, you’ll learn how to build an API server to interact with your blockchain and how to host your blockchain on a decentralized network. You’ll also build a consensus algorithm and use it to verify data and keep the entire blockchain network synchronized. In the concluding chapters, you’ll finish building your blockchain prototype and gain a thorough understanding of why blockchain technology is so secure and valuable. By the end of this book, you'll understand how decentralized blockchain networks function and why decentralization is such an important feature for securing a blockchain.

There is more than I was expecting to understand and it gently guides you through the making of a blockchain with the full comprehension of what you are doing. There is some error that in my opinion is what makes it even more fun. It can get pretty complicated for a beginner like me but if you are smart enought you will accept the challenge with a smile

I thought the description of how the blockchain works was very good, but if your going to teach someone about the programming aspect of it you need to make sure that your code is correct. So far, I have already found 3 errors in the code that he is showing in the book. What’s also confusing is that the code he has on GitHub is a bit different than what he is showing in the book. It took me over an hour to figure out that it wasn’t my fault it was his. As a programmer this is frustrating. :(

I found this book overall good for getting up to speed on how the blockchain works. The only thing i didnt like about it was it doesn't go into digital signatures and signing transactions. I found that in other books. Apart from that i think its a great intro into beginning to understand how blockchains work. Best way to have a deeper understanding is to get your hands dirty in code. Recommended.

Really badly written and outdated javascript for 2021. Please read mastering bitcoin if you want to create a blockchain from scratch.

Spent over an hour going in circles trying to get the promised code examples. Between Pakt Pub and Github, totally confusing and just didn't work. A pity, the book looks to be quite good.
