Greenpeace should mine Bitcoin to keep the margin low and save the planet from too profitable miners.

It sounds weird but I have a very compelling reason why we need more Bitcoin mining to save the planet. Been carrying this thought around for a year, can't find anything that can refute it. Maybe it's simply true. View quoted note →

If the hash rate doesn't increase but the price does, Bitcoin may become harmful to grids and compete with other electricity buyers. The only sustainable way forward is to increase the hash rate, decrease the margin of miners, and let them compete like dogs.

Deleted almost 1000 lines of code from Cashu Nutshell and got rid of 2 dependencies – feelsgoodman.gif Keep the foundation simple. Build complicated shit on top.

Halfway through the third book of "Three Body Problem" and I'm already getting anxiety from the prospect of finishing the book. Insane saga, it gets even better after the second half of the second book (thanks nostr:npub1emdtsxly9m68m00x206t574jttp65vk0c2m89ms038q047yz7ylqcac9awfor the tip). What epic science riction do you recommend for me next? The heavier the science, the better!

How do I disable the password protection of my key in Snort? Can't find the setting. @Kieran :)

I've made a list of Cashu libraries and awesome apps for the developers at ECASH HACKDAY 2K23 If you know of a project not in this list, comment below and I'll add it!

Someone posted an image of my encrypted nostr DMs on Twitter. Of course I know that it's possible to see the metadata but I didn't realize how creepy it feels. You can see who I talk to and when. You could deduce my social circles, maybe even real world activity related to my messaging patterns. From now on, I will stop using normal DMs on nostr. The traces they leave is horrifying and you shouldn't use DMs either. *Please do not send me any DMs from your npub if you have something to communicate to me.* Use a random npub or a giftwrap or use a different method or use a different network to reach me. Nostr DMs have always been a complete privacy hell and I urge anyone to realize this and act accordingly. I repeat: DO NOT DM ME. I WONT DM YOU.

Ecash mint without an every-growing database of spent tokens but a comparatively tiny accumulator. Sounds cool but tmk, a perfect accumulator hasn't been found yet. If the accumulator has a false-positive rate like a bloom filter, it would falsely flag unspent ecash as "already spent" effectively randomly buring some few of the user's tokens (you can control how little). It can be improved if the mint shares this accumulator publicly. When wallets want to mint tokens, they could "mine" for secrets that don't trigger a false positive hit with the accumulator. It's still not perfect because the accumulator is likely to change between the mint event and the spend (melt) event - which can again lead to new false positives.

I dream of building a Bitcoin-powered USD ecash system that doesn't rely on third parties to custody the mint's fiat balance but instead uses Lightning DLCs to stabilize the mint's reserves.

Ecash enables censorship resistant custodial wallets.

Today's Bitcoin ETF fiasco made an ETF approval by the SEC even less likely.
