Overview of this book

Blockchain and Hyperledger are open source technologies that power the development of decentralized applications. This Learning Path is your helpful reference for exploring and building blockchain networks using Ethereum, Hyperledger Fabric, and Hyperledger Composer. Blockchain Development with Hyperledger will start off by giving you an overview of blockchain and demonstrating how you can set up an Ethereum development environment for developing, packaging, building, and testing campaign-decentralized applications. You'll then explore the de facto language Solidity, which you can use to develop decentralized applications in Ethereum. Following this, you'll be able to configure Hyperledger Fabric and use it to build private blockchain networks and applications that connect to them. Toward the later chapters, you'll learn how to design and launch a network, and even implement smart contracts in chain code. By the end of this Learning Path, you'll be able to build and deploy your own decentralized applications by addressing the key pain points encountered in the blockchain life cycle. This Learning Path includes content from the following Packt products: • Blockchain Quick Start Guide by Xun (Brian) Wu and Weimin Sun • Hands-On Blockchain with Hyperledger by Nitin Gaur et al.

Chapter 13. Ethereum Fundamentals

Ethereum is an open source public blockchain and is considered to be an alternative coin to Bitcoin. A Canadian cryptocurrency researcher and programmer, Vitalik Buterin, proposed the idea in late 2013. Founded by an online crowdsale that took place in the middle of 2014, the platform went live at the end of July 2015. The DAO event in 2016 led to a hard fork, resulting in a split into Ethereum (ETH) and Ethereum Classic (ETC).

In this chapter, we cover the following topics about Ethereum:

  • Overview of Ethereum
  • Basic concepts such as ether, ERC20 tokens, smart contracts, EVM, gas, accounts, and oracles
  • The Ethereum performance issue and ongoing efforts to address the issue, such as PoS, Casper, Plasma, and Sharding
