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

In this chapter, we've discussed the near-term likely future of blockchain technology. It is impossible to know the future, but from what can be gauged, these are the industry trends and forces shaping the technology as it exists today. For those businesses investigating blockchain, each of these three major trends will act to either encourage blockchain adoption or cause avoidance. We hope that the governments of the world issue clear and well thought out regulation as soon as possible, as well as put in place safeguards to prevent fraud. With this in place, this technological evolution will have more guidance in terms of how to bring blockchain products to market safely and with less risk.

Blockchains, in general, will continue to be applied to different industries. It is unknown what new networks such as EOS and Cosmos will bring to the table, as no major chain has yet had the extensive governance models that these systems seek to provide. If large-scale, decentralized governance...
