A Block with Mir

In this block, I sit down with Walter Maffione, who leads the Kaleidoswap team, winner of the Cypher Tank 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.

In this very special block, I sit down with Giacomo Zucco… Bitcoin educator, entrepreneur, Cypher Tank judge, and, yes, my husband. This conversation is personal, funny, chaotic, and deeply connected to Bitcoin history. We start by looking back at some of the most meaningful “blocks” we have shared together since 2001, both in our personal life and in Bitcoin. Giacomo recalls one of the most important moments: the 2016 meeting in Milan that brought together several Lightning Network startups and implementations. That meeting helped lead to the BOLT specifications, also known at the time as the Milan Protocol, a key moment in the history of Lightning Network interoperability. We also talk about one of our latest adventures together: Cypher Tank. We discuss the origin & the future of Cypher Tank We also reflect on Lugano and the next four years of the Plan ₿ initiative. Giacomo explains what it feels like to be part of a city where Bitcoin is openly supported, where institutions are willing to listen, and where the community has grown from a handful of people to hundreds gathering around Bitcoin culture, education, and entrepreneurship. Finally, the conversation gets more personal and random… As always, of course. This episode is about Bitcoin history, building things before they are perfect, working with your partner, creating formats from scratch, and being part of something much bigger than yourself.

In this episode, I sit down with Preston Pysh, another incredible Bitcoiner who needs no introduction. Funny enough, we recorded this podcast while I was on a very long sabbatical from my own podcast. Now I’m back, and Preston is the one taking a break from his. It’s a beautiful conversation about: how people react when you go all-in on Bitcoin conviction and career change Bitcoin jobs Ego Death Capital Bitcoin education funding Bitcoin founders Bitcoin treasury companies humility in the Bitcoin space open-source thinking and, of course, Lugano! Enjoy! :)

In this episode, we sit down with Blake, the founder of Blitz Wallet and one of the standout builders from Cypher Tank. After placing third out of 149 applicants, Blake became one of the most talked-about participants of the format, not only because of the product, but because of the vision behind it: making Bitcoin easier to use without compromising what makes it powerful. We talk about his journey into Bitcoin, the family values that shaped his mindset, and the surreal moment when Brad Mills personally offered to invest in Blitz Wallet (followed shortly after by Willy Woo). Blake also shares how Blitz Wallet has evolved since Cypher Tank, including new features like Bitcoin gifts, designed to make onboarding smoother, and payment pools, which help groups collect and track funds directly inside the wallet. This is a conversation about Bitcoin, entrepreneurship, user experience, word of mouth, product-led marketing, and building tools that people actually want to use… and of course Italian randomness brought to you by me :) and don't forget: “Simplicity does not mean featureless"

Are you ready for another block? Or maybe even 2 or 3? :) The amazing @efenigson and I had so many topics to discuss! She is a constant personal inspiration to me as a podcaster and a marketing pro I deeply admire. One fil rouge that emerged from our conversation was the importance of professional proof of work. In the Bitcoin world, titles and credentials matter less than your ability to demonstrate value through action, integrity, communication, and authenticity. In Bitcoin, your real résumé is your proof of work. So let’s check it out. You’re not going to regret spending a few blocks joining this conversation.

A Block with Mir is back!!! With one of my favourite people in the space and he doesn't need any intro: JACK MALLERS! Not a new podcast… a comeback, actually. I started this in 2016. 10 years, 3 businesses, 2 kids, and 1 new country later, I promised myself I’d bring it back. 10-minute episodes, on average. Just like a Bitcoin block. Raw interviews. Personal stories. Randomness. Italian accent included. The common thread? My passion for Bitcoiners. Every guest has redefined life, value, and success in their own unique way. Every conversation has been so inspiring. . Subscribe to my podcast and come join us, 24 more episodes are already lined up
