Mastering Blockchain Programming with Solidity

Introduction to Blockchain

Blockchain technology was born with the invention of Bitcoin—a new form of peer-to-peer (P2P) electronic cashback 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...

Understanding blockchain

A blockchain is a timestamped series of immutable transactions that is managed by a cluster of computers using special computer algorithms. These immutable records are not owned by any single entity. A blockchain is a decentralized P2P network of nodes. Each node in a blockchain shares the same copy of data, also called the digital ledger. Each node present in the network uses the same algorithm to reach a consensus.

A blockchain, by design, is resistant to the modification of data. The ledger can record transactions between two parties in a verifiable and permanent way. Whenever there is a change in the ledger using transactions, changes are distributed to all the nodes, to verify and update their own copy of the ledger. Once a transaction is stored and verified by all the nodes in the network, then it is not feasible...

Introduction to Ethereum

Ethereum was proposed in 2013 by Vitalik Buterin, a cryptocurrency researcher and programmer. The first production release launched in 2015. Ethereum is an implementation of blockchain, and is an open source, public, and decentralized computing platform. Ethereum gained popularity because of its smart contract's features. Developers can program their smart contracts and execute them on the blockchain platform so that the full potential of the blockchain's different properties can be used.

Ethereum is for writing decentralized applications

As discussed before, Bitcoin uses blockchain technology for payments using bitcoins as a currency. Bitcoin also supports a scripting language, with which...

Smart contracts

Nick Szabo coined the term smart contract in 1994. Smart contracts are self-executing contracts. They eliminate intermediaries and allow direct P2P transactions. A smart contract has the power to automatically enforce some obligations. One of the best examples of this is a vending machine: when you need an item from a vending machine, you pay into it and it gives you that item without needing any middleman.

Smart contracts are very different from traditional software programs. Smart contract code is immutable once deployed on the blockchain. Because of this immutable property, we have to think twice before deploying it; otherwise, it could end up with critical flaws in production. A different mindset is required for writing smart contracts. Some smart contracts present in decentralized applications handle the flow of ETH or other ERC20 tokens, which have real...

Introduction to the Solidity language

Solidity is high-level language oriented for smart contracts. It is a Turing-complete language, influenced by C++, Python, and JavaScript.

Solidity is a statically typed language that supports inheritance, libraries, and complex user-defined types. Solidity is a bit different from the other languages; for example, Solidity does not have null values. Variables are initialized with their default values. Solidity also does not have any exception-handling mechanism to propagate exceptions.

Solidity support different data types including uint, int, address, and many more. As developers, we must know that Solidity does not have boundary checks for the uint and int data types. This makes these data types vulnerable to overflow or underflow.

At the time of writing this book, a major release of Solidity, version 0.5.0, has come...

Solidity data types

The Solidity language is statically typed. When writing a contract or library definition, all of the state variables and local variables must have the data type specified along with its declaration. There are many data types supported by Solidity. You can create your own custom type by using the data types supported by Solidity; for example, you can define your complex struct variable.

Solidity also has a support for the var keyword, used for dynamic data type. However, since Solidity version 0.4.20, the var keyword has been deprecated because of security concerns.

If we look at the Java language, it has primitive data types and reference data types. For reference data types, especially for instantiable class, the default value is null while initialization. However, in Solidity, there is no concept of null values. Instead of null, the...

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.

Who is this book for?

This book is for developers and data scientists who want to learn Ethereum, blockchain, and Solidity to write smart contracts and develop production-ready code. Basic knowledge of Solidity is assumed.

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

The book is well structured and written in simple language. The book provides a complete perspective of Solidity language and tools. It consists of- different properties of the blockchain- Ethereum terminologies and concepts with real life examples- how smart contracts are different from other programming language, how should a programmer's mindset needs to be changed for writing smart contracts- usage of Solidity development tools and commands- different Solidity design patterns, different types of security attacksI like the chapters related to ERC standards, Open Zeppelin, ZOS as many tips are provided, There is a chapter which teaches you how to create your own ERC-20 token or cryptocurrency from scratch.Print quality of the book is good. There are some commands in screenshots where text is smaller, but you can read with little bit of focus.

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...

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.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
