Overview of this book

Blockchain applications provide a single-shared ledger to eliminate trust issues involving multiple stakeholders. It is the main technical innovation of Bitcoin, where it serves as the public ledger for Bitcoin transactions. Blockchain Developer's Guide takes you through the electrifying world of blockchain technology. It begins with the basic design of a blockchain and elaborates concepts, such as Initial Coin Offerings (ICOs), tokens, smart contracts, and other related terminologies. You will then explore the components of Ethereum, such as Ether tokens, transactions, and smart contracts that you need to build simple DApps. Blockchain Developer's Guide also explains why you must specifically use Solidity for Ethereum-based projects and lets you explore different blockchains with easy-to-follow examples. You will learn a wide range of concepts - beginning with cryptography in cryptocurrencies and including ether security, mining, and smart contracts. You will learn how to use web sockets and various API services for Ethereum. By the end of this Learning Path, you will be able to build efficient decentralized applications. This Learning Path includes content from the following Packt products: • Blockchain Quick Reference by Brenn Hill, Samanyu Chopra, Paul Valencourt • Building Blockchain Projects by Narayan Prusty

Chapter 15. Ethereum Accounts and Ether Tokens

In the previous chapter, we discussed about Ethereum blockchain, its uses, and how it has shaped the decentralized technology, not for just currency based uses but also for other industry verticals. Further, we learned about development on top of the Ethereum blockchain, using smart contracts.

In this chapter, we will discuss the Ethereum account in detail and also study an ether token; this discussion will help us to better understand decentralized applications. We will also briefly discuss some popular Ethereum tokens and smart contracts. We will also discuss some important topics such as the transaction sub state, the validation of an Ethereum Block, and the various steps involved in the process of block finalization. Following this, we will briefly discuss some disadvantages of an Ethereum-based smart contract and currencies, toward the end of this chapter.

These are the topics which are covered in this chapter:

  • The Ethereum state transition...
