Show Notes

“If the internet could move value natively… would you use anything else?” I sit down with David Marcus, a true fintech veteran and the co-founder and CEO of Lightspark. You might know him from his time at PayPal, Meta where he led Messenger, or the ambitious Libra/Diem project. Now, he’s on a mission to build the open internet of money—on Bitcoin. We dive into David’s fascinating journey through startups, global payments, and Silicon Valley, before unpacking the philosophy and architecture behind Lightspark. We explore how Bitcoin is evolving beyond store of value into a...

Hello, fanboying here a bit, also think you were the first podcast we to read one of my comments into the consciousness of…anyone. :) as to your 100th episode question. Have you ever thought of an audience shift? I listened to Lyn Alden on Peter Mackormack’s show this week and her message was beautifully adjusted to his new audience. If you wanted to get your message out to another group, like Peter has, who would be your target audience?

This was one of my two favourites podcasts recently. For the same reason. Both guests, Lyn Alden here and Simon Dixon on Coin Stories, were outside of their usual comfort zone, and did great jobs framing things for the audience. It got me thinking how we need to meet people where they are. Cheers

Great episode! Up here in Kitchener, Ontario, Canada we have an active farmers market culture with a strong cash is king culture. I’m wondering if anyone listening here is from my area and would like to help to orange pill these folks? Also the idea of insisting on denominating in Sats; I lived in Mexico for two months once and by the end of that short time I had started to think in Pesos. It doesn’t take long. Cheers

Born in 1972, when I was kid living in Northern Ontario our local am station ran a « virtual » garage sale over the am radio waves every Sunday morning. It was awesome!

Mid and upper models of Flair Espresso maker are plastic free in the brewing areas and around $400-500. Tradeoff is it’s manual but that is just more proof of work. Pair with a metal hot water kettle and you’re all set.

As an educator AI is a tool to first draft output like report card comments, email responses, lessons plans, and unit planning. Essentially it has increased my productivity, reducing my hours, allowing me to spend more time on human interactions with my students and colleagues. Same result as when I started using online testing tools and translation software (second language teacher) as they became more effective over the last 2 decades.

As a teacher AI is a tool to draft my lesson plans, report card comments, and emails. I have ideas around using it for assessment that I have not tested yet. So my hours of work have been reduced, the quality of my Productions has increased, and my pay has remained unchanged.

Want to support the movie but a million sats is tough? Is there a lower tier where we can just buy our own copy?

The « othering » has to be exhausting:) go for a nap gents and when you wake up in that fog of between sleep and awake look for the love. Bang on though about Canada and jail. We have a tradition of shacking up or going to jail around November, or if we are really tough right after Christmas, to avoid the winter, get fed, and not freeze to death.

2 points: Humans fail not gold -Peter Schiff (Exactly-therefore a trustless system takes humans out of the equation for the win and its Bitcoin) And « If I owned all the bitcoin it would be worth nothing; if I owned all the gold I’d be rich » again Peter…would you? If one person owned all the gold I don’t know that I’d want any, anymore, am I missing something here?

This reminds me of the first book I read on blockchains « The Truth Machine ». Always building your reputation, still as anonymous as you choose, and your reputation still has value. Way down the line, but could you imagine a « sorry » button? And a « forgiven » button? Seems people either say nothing for fear of becoming a meme, or hide behind burner accounts, and have no guard rails. Wouldn’t it be nice to feel you could fuck up and make amends?

This is the second or third podcast I’ve heard Saif share this theory and the more I struggle with it the more it is influencing my thinking. This was a sad hard fork. How do we avoid them in the future?

Genuinely enjoying this space, so different than “number go up” 24/7, thank you for that. Question, is there any folklore around the 21 million number? Why did Satoshi decide on 21? Many thanks.

A number of questions…how is Elon less of a ruler, by definition, not trying to be argumentative, and do we not delay the process of embracing the power of decentralization when we speak about the « rulers » we don’t hate like they are somehow better than the ones we do? If Elon wants my support tokenize and dentralize X and buy some of the coins.

    7-10 years…wow…and yes I can see it happening « a little bit at a time, then all at once ». Canada needs to make regulatory decisions that will allow companies like Square to offer Bitcoin as a payment option like they have in the states
