Vitalik Buterin is the Russian-Canadian programmer who, at age 19, wrote the Ethereum whitepaper and changed what a blockchain could be. He turned a programmable ledger into an idea engine - smart contracts, DeFi, NFTs, DAOs - and then spent years fighting to keep it decentralized. He travels with a single suitcase, posts thousand-word blog essays at 2am, and once cried over a World of Warcraft nerf that indirectly launched a $200B ecosystem.
Kathleen Breitman is the co-founder and CEO of Dynamic Ledger Solutions, the company behind Tezos — the self-amending blockchain that raised $232 million in a 2017 ICO, then the largest in history. A Cornell-educated economist turned crypto builder, Breitman navigated one of the most turbulent governance crises in blockchain history to deliver a live, functioning network. Known for her blunt wit, anti-hype stance, and combative advocacy during the Tezos legal battles, she has become a defining voice in the 'build it or shut up' wing of the crypto world. She is currently building Coase, a software company focused on reducing transaction costs, while serving as a venture partner at Social Impact Capital and writing pointed op-eds for Fortune about crypto culture, women in tech, and the industry's credibility problem.
