Cryptocurrency is revolutionizing the global financial system and shaking up our perception of trust. Joseph Lubin, co-founder of Ethereum, says the digital currency’s open-source, decentralized system is the opposite of what we’re used to — a bank-led financial system built in backrooms. “It’s a new kind of trust foundation for the planet,” he says. In a conversation with Gillian Tett, US editor at large of the Financial Times, Lubin talks about the difference between Ethereum and Bitcoin, what Ethereum is doing about its carbon footprint, whether the system is vulnerable to cyber criminals, and why people should trust it. The conversation is wide-ranging and meant for for crypto neophytes and seasoned investors alike.
