Episode notes

In this block, I sit down with Walter Maffione, who leads the Kaleidoswap team, winner of @Cyphertank

Walter is building Kaleidoswap, a Bitcoin product focused on swaps across Bitcoin layers. We talk about how the project started from a real need, how the team came together through a hackathon, and why interoperability may become one of the most important challenges for the next generation of Bitcoin products.

We also discuss RGB, Lightning, Bitcoin layer 2s, Turin’s growing Bitcoin scene, BitPolito, Satoshi Spritz, Bitcoin Torino, Italy’s first BitDevs, and what it means to actually build and ship in Bitcoin.
