006 | Libra, crypto, and the future of humanity

Gianluca and Jared are joined by crypto expert Thomas Tumiel in a discussion about the details of Facebook’s new Libra cryptocurrency. They give a brief primer on the fundamentals of blockchains and cryptography, examine how Libra is implemented (compared to Bitcoin and Ethereum), discuss Facebook’s strategy for rollout, consider possible failure modes, and contrast the dystopian and utopian outcomes of a truly global cryptocurrency.
