my first hardware project: an offline cashu wallet on an esp32. generate ecash, send it to the esp32 via bluetooth, esp32 decodes the ecash into individual proofs, pick any proof and display it as a QR code for redemption. the esp32 never touches the internet. completely airgapped. just receives tokens, holds them, and displays cashu tokens.

been working on making bitcoin payments boring. it's so much fun.

being a cashu disrespector must be exhausting. so many people building and shipping, new developments constantly. you have to wake up every day and keep fading it. can’t be easy.

gm. check out this episode about the guys who built the transatlantic telegraph cable. they failed over 3 times but remained locked in and eventually succeeded. we really need more people out there working on ambitious, human scaled projects like this.

i want to speak to satoshi nakamoto and tell him i’m doing the best i can, but there’s simply so much to do.

been reflecting on the bitcoin for signal campaign. i want to share why we designed it in the way we did. a lot of bitcoin projects try to get people to come to them. 'latest layer 2/ecash/ark/lightning/spark/liquid!' 'simple wallet!' 'frictionless onboarding!' i think that's not always the best approach. instead of promoting a new app or asking people to meet us, we should try to meet people where they already are and then make the case for bitcoin. millions already use signal everyday so why ask them to go somewhere else for private payments? bring bitcoin to them instead. i want to see more projects try to integrate bitcoin where people already hangout. cashapp nailed this imo. they didn't build a bitcoin app and ask people to come. they integrated bitcoin into a space that people already use to send $ to friends. try to follow that playbook.

i like how this shader reveal and hover effect is turning out.

refreshing to come across a site like this

Pierre Computer Company

i'm convinced the people who majorly move the needle on improving human life are civil engineers, computer programmers, electrical engineers, physicists, structural engineers, medical researchers etc...not politicians, nonprofit workers, or advocacy groups.

“who will run the mints?” i come from piracy/private trackers/ torrents. i know exactly who will: the same type of people motivated to keep torrent trackers alive. a wise man once said: “what the piratebay learned is that in the game of whack a mole, the moles win.”

milton friedman in 1990 on the future development of perfectly private ecash. i appreciate how he describes the push ux of ecash as just like handing someone a dollar bill.

GM. What do you think about these Cashu shirts?

Hello @hal
