The shipping container brought standardization to the way we move goods around the world. Similarly, TCP/IP packets normalized how information transits over computer networks. Today, blockchains remain siloed ecosystems and interoperability is practically non-existent. A new wave of third-generation blockchain protocols aims to change this. In this new paradigm, blockchains communicate natively and value moves seamlessly from one network to another. One of those projects is Cosmos.

We're joined by Ethan Buchman and Sunny Aggarwal of Cosmos. With its recent mainnet launch, we discuss how the network is running and address potential issues relating to governance and centralization of power.
