Introduction to Blockchain

Blockchain technology was born with the invention of Bitcoin—a new form of peer-to-peer (P2P) electronic cash—back in 2008. The Bitcoin white paper was released on October 31, 2008 and the first release of Bitcoin came on January 3, 2009. The blockchain space is still a toddler in terms of adoption and the tools available. It has some unique properties that did not exist before in any of the previous systems or software applications. The most important property of blockchain is establishing trust between two or multiple parties without needing any intermediaries, which opens a new era in programming.

Ethereum is one of the implementations of blockchain. Ethereum is an open source, public, and distributed computing platform. On Ethereum, developers can deploy smart contracts written in the Solidity...

Key benefits

Delve into Solidity and understand control structures, function calls, and variable scopes

Explore tools for developing, testing, and debugging your blockchain applications

Learn advanced design patterns and best practices for writing secure smart contracts

Description

Solidity is among the most popular and contract-oriented programming languages used for writing decentralized applications (DApps) on Ethereum blockchain. If you’re looking to perfect your skills in writing professional-grade smart contracts using Solidity, this book can help. You will get started with a detailed introduction to blockchain, smart contracts, and Ethereum, while also gaining useful insights into the Solidity programming language. A dedicated section will then take you through the different Ethereum Request for Comments (ERC) standards, including ERC-20, ERC-223, and ERC-721, and demonstrate how you can choose among these standards while writing smart contracts. As you approach later chapters, you will cover the different smart contracts available for use in libraries such as OpenZeppelin. You’ll also learn to use different open source tools to test, review and improve the quality of your code and make it production-ready. Toward the end of this book, you’ll get to grips with techniques such as adding security to smart contracts, and gain insights into various security considerations. By the end of this book, you will have the skills you need to write secure, production-ready smart contracts in Solidity from scratch for decentralized applications on Ethereum blockchain.

What you will learn

Test and debug smart contracts with Truffle, Ganache, Remix, and MetaMask

Gain insights into maintaining code quality with different tools

Get up to speed with ERC standards such as ERC-20 and ERC-721

Become adept at using design patterns while writing smart contracts

Use MultiSignature (MultiSig) wallets and improve the security of contracts

Use Oracle services to fetch information from outside the blockchain

The book is already way outdated but that's not the real problem, nor is the confusing language, nor the random bits of information that are randomly introduced (without sufficient explanation) at odd times in places where they are not relevant to the topic. The very first rule of publishing a technical book should be not to include any long code the reader should not understand yet at that point, without explaining the code in detail. Pages 64-66 are full of code but the author is like, "look here at these lines in bold" to understand the concept, but those lines are meaningless without the non-bold lines. Trying to read the whole contract is an exercise in frustration because you lack the knowledge at this point, and really what you want is someone to walk you through it. I'm trying to become an expert on Smart Contracts. So do I go further on in the book without understanding the example, or do I spend more time on it than the hour I have already spent? No, I trashed this book and fell back on the Solidity docs online. The last thing I need when learning something new is an confusing book with confusing examples and a lot irrelevant and out of place information everywhere. I could give more examples but this was the one that got me, right in chapter 2. I pride myself on my ability to read poorly-written technical books, so I view my frustrations here as the author's failure.EDIT: Another thing I've realized is that the book often describes topics by mentioning other topics that haven't been explained. For example, in Chapter 2 there are that are described as producing packed bytes. The book mentions packed data multiple times but never explains or defines it, so all you can really do is ignore what they're saying. And then in some cases they give textbook definitions of things that a beginner wouldn't understand, and then they're like "here is an example of how to use it." But the example they give really doesn't give you any idea how or why it would be used. Ultimately, if these things were cut out of the book entirely it would not change the amount of usable information contained in the book, but it would be much easier to read. This is one of those books where it takes FOREVER to get through a section because you're trying really hard to actually understand it, and half the time when you've completed the section you didn't really learn anything at all.EDIT 2: I'm changing my review to one star. There are obvious bugs that are guaranteed to confuse people and waste their time. In Ch. 3 there is an example for child contracts, where the function to create a child contract returns an address. However, in the code it returns a ChildContract type. So this launched me on a search (outside of the book) to figure out why a ChildContract is (or returns) an address. I was going to ask some devs, so I looked for the codebase on Github to show them the example, and I found it. Interestingly, in the same code on Github, that error is not present. So it seems the author is correcting these errors for a future edition. I only wish the author had tested his code a bit and maybe had someone else take a look at this edition before it was published. I wonder how much of my other difficulty wading through the book was due to small errors that I wasn't knowledgeable enough to catch. This poor editing of technical books is becoming the norm in the industry for some reason, even though these kinds of books make a lot of money and absolutely need to be accurate.

sample codes in this book using -> pragma solidity 0.5.3That's pretty old, and library talked in this book like openzeppelin which current name openzeppelin-contracts is too old.So basically you need to learn by yourself with the newest documents github, after that you are able to know what changed.It's a good book to get the knowledge for ethereum in a certain degree, but not to do code work practically.

Poor and incomplete explanations and solidity version is too old. Looks like book was put together too hastily and the the editor did not do a good review or wasn't technical. Going to buy a different book after being frustrated with the first 135 pages.

Alright book. Several lazy/sloppy mistakes, including nonsensical sentences that were just not reviewed prior to publishing. The content is decent, but presented in a very interesting or compelling way. I'd suggest just following online tutorials over buying...
