2025 was my first year working on Bitcoin full time and honestly, it’s been nothing short of incredible. I’m deeply grateful for the people I met along the way, the friendships that grew out of this space, and the inspiring projects I had the privilege to contribute to.
If there’s one thing this year truly taught me, it’s that we’re winning, ladies and gentlemen. Being able to witness this moment firsthand, to build, learn, and grow alongside so many brilliant minds, is something I don’t take for granted.
Feeling excited, humbled, and incredibly stoked to be here for what’s coming next. Happy new years and lots of love to all of you 💜

I think my Bitaxe is broken. It’s been a week and still no block found… pfff
Some vibes, yes. But the wallet part is powered by https://github.com/cashubtc/coco and the UI is shadcn, so there wasn’t much to build left ^^
Spent my Christmas holiday cooking up the most requested npubx.cash feature :>
She decided that she’d like to get up at 3am today. After two hours of reading her favourite stories and some tea, she is fast asleep and I am working on nostr logins 😍
Going to be a tough day, but working in the dark while listening to her breathing is worth every bit of it
Interesting! What client? Working fine for me.
Absolutely! My post was in no way meant to imply that Bitcoin wasn’t the superior money. I just never understood why some people have a hard time understanding it.
Difficulty itself is intersubjective too. Bitcoin objectively does not require any energy to run. These are the rules that we agreed on.
However I do agree that these intersubjective rules anchor Bitcoin in objective reality.
I think I just understood why people have a hard time comparing Bitcoin and Gold. Gold is objective (its value is not, but its existence is), but Bitcoin is an intersubjective thing. In this regard it’s not different from Fiat currency. Bitcoin does not exists outside of our conscious mind.
Of course that is true for many many things and it does not make Bitcoin any less valuable. But somehow thinking about this makes me understand the old and wary folk a bit more.
Sometimes the best gifts are the coincidental ones 🤙🎅🏼
Merry Christmas nostr ❤️
New machine? If so, congrats! Frameworks are the best
I have not haha, will look it up. Someone gifted me one of his books and I just started readin

I have pushed the repositories for my native SwiftUI app CocoCashuApp that I have developed with great inspiration from nostr:npub1mhcr4j594hsrnen594d7700n2t03n8gdx83zhxzculk6sh9nhwlq7uc226 coco-cashu. CocoCashuApp is a native, cross-platform Cashu wallet for iOS and macOS, built specifically for the Swift ecosystem. CocoCashu demonstrates how to build a self-custodial ecash wallet using the CocoCashuSwift library at https://github.com/imyrvold/CocoCashuSwift. The app itself is available at https://github.com/imyrvold/CocoCashuApp.
This looks great! Lots is still mocked, right? I have only quickly glanced over the files, maybe I was looking in the wrong place.
You might want to look into CDK as well. It’s a battle-tested Cashu implementation written in rust and they got Swift bindings too!
Oh yeah! Thank you for reminding me, I always wanted to try Zed. It’s written in Rust, right?
Finally found my favourite AI stack:
nvim + claudecode.nvim
Configure claudecode.nvim to use an external terminal, then I can have Claude running on a second workspace, while diffs are still being rendered in nvim splits. I miss Cursor Tabs, but it’s not too bad actually.
You know my answer! Paying with nuts all day long. 🥜
No more GitHub — publish your git repos on Blossom:
---
cargo install hashtree-cli
cd your_repo
# self is an auto-generated nostr identity (nsec) in ~/.hashtree/keys
git remote add htree htree://self/your_repo
git push htree master
clone:
git clone htree://npub1xndmdgymsf4a34rzr7346vp8qcptxf75pjqweh8naa8rklgxpfqqmfjtce/hashtree-rs
view at files.iris.to e.g. https://files.iris.to/#/npub1xndmdgymsf4a34rzr7346vp8qcptxf75pjqweh8naa8rklgxpfqqmfjtce/hashtree-rs

I believe AI will be actually good for freedom tech: soon everyone will have the resources to create the software they need, not just big tech.
Wow 👀
This is really cool!
Oh noooo… and nostr:npub1a00wj229auzjswlq4s77y4u8eqdx5k9ppatgl8rtv8va65f6mwksum9q3h are on nostr too 😭 seems like they don’t leave me a chance haha 😅
Coco-Cashu has officially moved to the cashubtc Github repository: https://github.com/cashubtc/coco-cashu
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)

coco-cashu can now also handle pre-existing mint quotes, when they are added using the new addExistingMintQuote API.
As a result you can implement a working npub.cash wallet in minutes using coco-cashu and npubcash-sdk 🔥
Cashu.me might have to be opened for NWC to work. Not sure though. nostr:nprofile1qqs9pk20ctv9srrg9vr354p03v0rrgsqkpggh2u45va77zz4mu5p6ccpr9mhxue69uhhyetvv9ujuumwdae8gtnnda3kjctv9uq32amnwvaz7tmjv4kxz7fwv3sk6atn9e5k7tc8ju2t2 might know what’s up
We are actually thinking about selling these at some point. My wife is just getting into it. She is not complete satisfied with the result yet, and she wants to make them perfect before taking money.
Go!

But creating POW that equals a users mobile device on cloud is essentially free
Kicking off the day with a broken starter and waiting for AAA. LFG 🤙
Omarchy v2 is out and it's beautiful! 
I hope for this to become the easiest way to build a Cashu wallet in any typescript environment
