This week on YOU, host Claire L. Evans digs into blockchain, this trendy new thing everyone seems to be talking about—but that no one really seems to understand. Our guest Saya Iwasaki of Bitski talks about the mysterious origins of blockchain; how it’s being used to protect our money, our information, our art, and our identities; and its potential to change the entire internet—and possibly the world—forever. Artist Mitchell Chan explores the uses and philosophy of blockchain in conceptual art, and Grayson Earle and Maya Binyam talk about using blockchain to make bail.
