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 16. Decentralized Applications

Decentralized Applications (DApps) are applications that run across a decentralized network and are not owned or controlled by a centralized authority. They differ from distributed applications primarily in terms of ownership. A distributed application may run on thousands of computers, but those computers and the management of the software running on them are controlled by a central authority—Amazon, Microsoft, and so on. A decentralized application runs on what is typically a peer-to-peer network and is designed in such a way that no one person or organization can control the functioning of the application. A decentralized application does not require a blockchain. There were multiple decentralized applications before blockchain: BitTorrent, Tor, and Mastodon are all decentralized applications that exist without the use of a blockchain.

In this chapter, we are going to cover the following:

  • The major features of a decentralized application
  • The largest...
