Proof Of Work

A beautifully produced anthology of crypto-artist, writer, and hacker Rhea Myers's pioneering blockchain art, along with a selection of her essays, reviews, and fictions. DAO? BTC? NFT? ETH? ART? WTF? HODL as OG crypto-artist, writer, and hacker Rhea Myers searches for faces in cryptographic hashes, follows a day in the life of a young shibe in the year 2032, and patiently explains why all art should be destructively uploaded to the blockchain. Now an acknowledged pioneer whose work has graced the auction room at Sotheby’s, Myers embarked on her first art projects focusing on blockchain tech in 2011, making her one of the first artists to engage in creative, speculative, and conceptual engagements with "the new internet." Proof of Work brings together annotated presentations of Myers’s blockchain artworks along with her essays, reviews, and fictions—a sustained critical encounter between the cultures and histories of the artworld and crypto-utopianism, technically accomplished but always generously demystifying and often mischievous. Her deep understanding of the technical history and debates around blockchain technology is complemented by a broader sense of the crypto movement and the artistic and political sensibilities that accompanied its ascendancy. Remodeling the tropes of conceptual art and net.art to explore what blockchain technology reveals about our concepts of value, culture, and currency, Myers’s work has become required viewing for anyone interested in the future of art, consensus, law, and collectivity.

The new book from one of TIME's 2021 most influential people Author was in Forbes 30 Under 30 Hall of Fame "A crucial contribution to development of a new technology that will impact all of our lives.” –Laura Shin, host of the Unchained podcast and author of The Cryptopians: Idealism, Greed, Lies, and the Making of the First Big Cryptocurrency Craze “Vitalik Buterin is one of the most influential creators of our generation....Like most of his work, it is sure to become a must-read.”–Camila Russo, author of The Infinite Machine, founder of The Defiant The ideas behind Ethereum in the words of its founder, describing a radical vision for more than a digital currency—reinventing organizations, economics, and democracy itself in the age of the internet. When he was only nineteen years old, in late 2013, Vitalik Buterin published a visionary paper outlining the ideas behind what would become Ethereum. He proposed to take what Bitcoin did for currency—replace government and corporate power with power shared among users—and apply it to everyday apps, organizations, and society as a whole. Now, less than a decade later, Ethereum is the second-most-valuable cryptocurrency and serves as the foundation for the weird new world of NFT artworks, virtual real estate in the metaverse, and decentralized autonomous organizations. The essays in Proof of Stake have guided Ethereum’s community of radicals and builders. Here for the first time they are collected from across the internet for new readers. They reveal Buterin as a lively, creative thinker, relentlessly curious and adventuresome in exploring the consequences of his invention. His writing stands in contrast to the hype that so often accompanies crypto in the public imagination. He presents it instead as a fascinating set of social, economic, and political possibilities, opening a window into a conversation that far more of us could be having. Media scholar Nathan Schneider provides introductions and notes.

This book constitutes the refereed proceedings of three workshops heldat the 20th International Conference on Financial Cryptography and DataSecurity, FC 2016, in Christ Church, Barbados, in February 2016. The 22 full papers presented were carefully reviewed and selected from 49 submissions. They feature the outcome of the Second Workshop on Bitcoin and Blockchain Research, BITCOIN 2016, the First Workshop on Secure Voting Systems, VOTING 2016, and the 4th Workshop on Encrypted Computing and Applied Homomorphic Cryptography, WAHC 2016.
