I have finally started to gather all my presentations, workshops and podcasts about Cashu. I will try to keep this list updated from now on 😉

Coco RC10 is out for testing, including an API to pause and resume subscription services. This is helpful for environments where the OS will take over and kill processes and sockets (e.g. backgrounding an app on iOS). Read more about this here:

Cashu out of the box

The Bitcoin Forum Ingolstadt was an absolute blast! So many great people, lots of inspiring conversation and as always so much Cashu 🥜💜 Best Bitcoin ice by Beppo Best haircut paid in sats by @Hairtoshi_21 The best memes and giggles (and best in class seed storage) by @npub1r834...wym8 BitBox team rocking their booth 14 hours a day I will be coming back next year 🙌🏻

Someone should build a web of trust service, based on a sophisticated graph based database. The service should tell me immediately which pubkeys are within n hops of me. Then monetize it with Cashu-402

Felt cute, might delete later

If you understand some German you should come to the 3rd Bitcoin Forum in Ingolstadt! Of course I’ll be giving a presentation on Cashu 🥜 and whether it is the next layer on Lightning. ⚡️ We will go into Cashu applications, and how it can extend the Lightning network to allow for new usecases! 🎟️ Tickets: https://copiaro.com/bitcoinforum/lightning-day More information about the event: 👉

A house full of runny noses and a conference ahead in 3 days… time to get out the big guns! Chicken stocks here to safe the day

I caught a cold and could not really concentrate on code for a couple days, but I used the time wisely and have updated most of the documentation around npub.cash v2! Find new docs about deployment and the client side SDK on https://docs.npub.cash! The npubcash-sdk now also contains proper JSdocs annotations for easier use. And now that I fought the fever with docs, lets get back to coding!

Audible, if I were you I’d check my algorithm

FOSS will win 🧡

The new npubx.cash interface driven by coco-cashu is coming along super nice! Pretty much all of the Cashu logic is handled out-of-the-box by coco-cashu and coco-cashu-plugin-npc (which now supports websocket updates too, so payments can be automatically redeemed)

I have not implemented NIP-46 for a while... The UX has certainly come a looong way. This is so smooth!

👀

When I started to work on npubx.cash I thought that this new version would not have a frontend like the old version did. The reason being, that it works best when integrated into a fully persisted and feature complete Cashu wallet. And I did not want to build a full wallet app just for npubx.cash... Well thanks to coco-cashu this has now become a matter of UI design alone. With coco-cashu-core and coco-cashu-plugin-npc you get a full wallet with npub.cash integration out of the box. All that is left is some UI work.

The goal of coco is to give you the “just-works-out-of-the-box” Cashu treatment, while at the same time being modular and extendable. It’s pretty new and early in development, but if you are building an MVP please give it a spin and let me know how it went! 💜 View quoted note →
