Man, DDD is tough :/

Testing npub.cash v2. Pls zap this

Cashu-TS v2.5 released Hey everyone! We just pushed a new version of Cashu-TS through the gates! The most notable feature included is NUT-21/22 Blinded Authentication. Other than that the release includes a great deal of fixes and DX improvements. It also includes PRs from FIVE new contributors! 🔥💜 As always, please try to break it and open an issue if you find anything! https://www.npmjs.com/package/@cashu/cashu-ts

This is going to be fun!

I'll be hosting another Cashu workshop soon! This time, it will be more of a consumer-friendly introduction. If you were attending, what topics would you most like to see covered?

Sneak preview: clipstr - A clipboard manager that lives on nostr! I recently started transitioning from my Macbook to a Linux machine and the only thing I miss is a synchronised clipboard between my devices. This made working on multiple workstations and with my phone a breez! Because I missed this so much I started having a clipboard text file that I synced between my devices using SyncThing, but it was not the real deal. Then I realised that I already work with the perfect syncing layer every single day... nostr! clipstr uses nostr events to your clipboard registry. It can set or get entries and print them to stdout, meaning you can easily pipe them into your OS' native clipboard when desired. Because it is build on nostr, it is easy to add GUI clients or access the registry through a browser. I did not get to polish and release it. But I wanted to share a demo regardless. Wdyt?

I love nostr. Had a massive issue in my day-to-day dev flow. Nostr fixed it. Will Share the Code later today 💜

The most seamless way of internet payments:

Cashu 402

Bitcoin changed my life

Coinbase jumped on the 402 bandwagon... yay! When I talk to people about Cashu they usually ask me: "Why do we need Cashu? We got Bitcoin and Lightning". I used to tell them that Cashu offers a great alternative to custodial Lightning, but with better privacy. While this remains true, my answer today is that Cashu enables new use cases (or simplifies them drastically) where Lightning and Bitcoin struggle. One example are Zaps. NIP-61 Zaps offer a very similar experience and value proposition as NIP-57 Zaps do, but require only a fraction of the implementation overhead. The second example (and inspiration for this post) is HTTP 402. With Cashu, we can streamline payments for requested ressources into a single request. Because Cashu is a bearer asset the whole flow is pretty stateless. It is stupid simple to implement this. While it is definitely possible to make 402 work with other "assets", using Bitcoin / Cashu makes it a breez. This is my favourite thing about Cashu.

GM! Found an issue in almnd that causes subscriptions to not get cancelled properly. Patch is incoming 🫂

If you shuffle a deck of cards you will create a unique combination that has never been created before Numbers at that scale are mind blowing 🤯

How does one become a great software engineer?

The npubcash backend is only ~3300 lines of code… feels kinda weird thinking about how many many hours I have spent working on this

Found this on Reddit. What an amazing idea to visualise Bitcoin outperforming everything! Someone should stamp a seed in a house foundation and sell the first casascius house lmao

Can't stop refactoring. Pls send help

First end-to-end test of npub.cash V2 in Cashu.me succeeded! 🥜💜

I will be hosting multiple Cashu workshops for beginners and intermediates this year. I am fine tuning the slides right now and thought that I could record a free web course using the materials. Would you watch that?
