Proof of Stake

After Ethereum creator Vitalik Buterin dropped out of college and launched Bitcoin Magazine, he wrote the Ethereum white paper, which proposed an open source protocol that would take what Bitcoin did for money and do it for everything else: contracts, social networks, and sharing economies. Now, less than a decade later, his idea is valued at about half a trillion dollars, and it is the foundation for the weird new world of NFT artworks, virtual real estate, and decentralized autonomous organizations.

This book is a collection of essays including “On Free Speech,” which creates a whole new standard for free speech and how to protect it; “Prediction Markets: Tales from the Election,” in which Buterin bets on the Trump-Biden election before and after it was decided, and how the prediction markets help explain the political situation today where so many believe Trump won; and the last essay in the book, “Crypto Cities,” where Buterin observes the beginnings already in motion of a future where cities governed through blockchain better serve the public good than governing political institutions do today.
