In 2009, an anonymous figure presented the world with an entirely new class of technology, one that has gone on to reshape technology and human collaboration in unprecedented ways. This inflection point, Bitcoin, was designed as a form of digital gold and remains this way today. Yet, Bitcoin did not open the doors of cryptocurrency to the world-Ethereum did, and while Bitcoin is a currency, Ethereum is a technology-a new way of doing things in an increasingly digital world. Less than a decade since inception, Ethereum has grown to a half-trillion dollars and one-hundred million unique addresses, and continues to push innovation through novel standards, massive scale, and an ever-widening community. Into the Ether is a testament to the story and workings of Ethereum, blockchain, smart contracts, and decentralized finance, and introduces a comprehensive set of knowledge on all things related to the technology and ideas that power the Ethereum ecosystem. For novices, beginners, and enthusiasts alike, Into the Ether is here to help you figure out exactly what all this crypto stuff is, why it matters, and how to benefit from it, all viewed through the Ethereum revolution.
