Ripple CEO Brad Garlinghouse talks with Recode's Kara Swisher about bringing legitimate financial institutions into the formerly-sketchy world of blockchain and cryptocurrencies. In this episode: Garlinghouse's background at Excite@Home, Dialpad, and Yahoo; the "peanut butter manifesto" memo he wrote at Yahoo; moving on to Silver Lake Partners, AOL, and then becoming CEO of Hightail; being recruited to Ripple; the appeal of blockchain and cryptocurrency; working with the banks, not against them; the coming revolution in cross-border transactions; why bitcoin speculators were actually "forward progress"; will there be one cryptocurrency to rule them all?; the "unbanked" people of the world; potential problems facing cryptocurrency; convincing regulators and established banks; why should a big bank like Citi work with Ripple?; who will disrupt the incumbents?; the actual uses of crypto for consumers; and Facebook and tech's responsibility.
