Discover the advanced features of Solidity that will help you write high-quality code and develop secure smart contracts with the latest ERC standards

Key FeaturesDelve into Solidity and understand control structures, function calls, and variable scopesExplore tools for developing, testing, and debugging your blockchain applicationsLearn advanced design patterns and best practices for writing secure smart contractsBook 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 learnTest and debug smart contracts with Truffle, Ganache, Remix, and MetaMaskGain insights into maintaining code quality with different toolsGet up to speed with ERC standards such as ERC-20 and ERC-721Become adept at using design patterns while writing smart contractsUse MultiSignature (MultiSig) wallets and improve the security of contractsUse Oracle services to fetch information from outside the blockchainWho this book is 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.

The application of private international law to electronic consumer contracts raises new, complex, and controversial questions. It is new because consumer protection was not a private international law concern until very recently and e-commerce only became an important commercial activity within the last ten years. E-consumer contracts generate original questions which have not been considered under traditional private international law theories. It is complex because it has to deal both with difficulties raised by consumer contracts and the challenges of e-commerce. Reasonable resolutions to consumer contracts may prove inappropriate in e-commerce, while effective approaches to resolving private international law problems in e-commerce may be improper for consumer contracts. It is controversial because it concerns the conflicting interests of consumers and businesses in a fast-moving commercial environment - a fair balance is therefore hard to achieve. Without proper solutions provided by private international law, consumers will not be confident about purchasing online, and businesses will face unreasonable risk and participation costs in e-commerce. Updated and properly designed private international law rules are essential to the further development of e-commerce. This book aims to provide an answer to the urgent requirement for legal certainty, security and justice in e-consumer contracts. It is primarily concerned with existing approaches to jurisdiction and choice of law issues in e-consumer contracts in the European Community and England, but some typical approaches in other jurisdictions are also examined. Based on the analysis and the comparative study of the existing law, the book seeks to provide a proposal as to what the law should be in order to provide certainty to both parties, to provide reasonable protection to consumers, and to promote the development of e-commerce.

Examining the maximization of consumer protection via the consumer's jurisdiction and law, this volume discusses how to improve the efficiency of juridical protection for consumers who contract with foreign sellers by electronic means and offers recommendations which provide a basis for the consumer to sue in his own jurisdiction and for the law of the consumer's domicile to apply.
