A Block with Mir

A Block with Mir & Blake Kaufman (Blitz Wallet)

Wed, 27 May 2026 13:00:28 GMT

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"

A Block with Mir & Efrat Fenigson

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 & Jack Mallers

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.
