Learn Ethereum - Second Edition

By: Xun (Brian) Wu, Zhihong Zou, Dongying Song

Overview of this book

Ethereum is a blockchain-based, decentralized computing platform that allows you to run smart contracts. With this book, you’ll discover the latest Ethereum tools, frameworks, wallets, and layer 2, along with setting up and running decentralized applications for the complete, end-to-end development experience. Learn Ethereum, 2nd Edition is a comprehensive overview of the Ethereum ecosystem, exploring its concepts, mechanisms, and decentralized application development process. You’ll delve into Ethereum's internals, technologies, and tools, including Ethereum 2.0 and the Ethereum Virtual Machine (EVM), gas, and its account systems. You’ll also explore Ethereum's transition to proof of stake, L1/L2 scaling solutions, DeFi protocols, and the current marketplace. Additionally, you’ll learn about EVM-compatible blockchains, connectivity techniques, and advanced topics such as sharding, off-chain scaling, DAOs, Metaverse, and NFTs. By the end of this book, you’ll be well-equipped to write smart contracts and develop, test, and deploy DApps using various tools, wallets, and frameworks.

Types of smart contract

With the increasing adoption of blockchain-based solutions, more and more organizations are involving developing DApp and smart contracts. There are smart contracts and protocols classified into roughly three categories: Smart Legal Contracts, DAO, and Application Logic Contracts (ALCs).

Let us understand them briefly:

  • Smart Legal Contracts: Smart legal contracts are a type of smart contract. A well-defined smart contract can run automatically in the blockchain. When smart contract logic is a binding legal contract and executing code based on connected terms with a legally enforceable, the correspondent parties need to follow contract legal agreements to satisfy their contractual obligations. Smart legal contracts need to be human-readable and machine-readable agreements that consist of natural language and com-putable components. The human-readable agreement requires all parties involved in contracts to understand and agree with the contract. They...
