In this week’s episode, Anna dives back into the Polkadot world with friend and occasional co-host Rob Habermeier from Parity. They cover XCM - the Cross-Consensus Messaging format - and how XCM allows parachains to speak to one another, passing messages through the validators on the relay chain via XCMP Cross-Chain Message Passing.
