An experimental promo video for Arké about how bitcoin is a bit like a public park. Working on the app is fun, but man do I sometimes need creative side quests when Claude rattles on and on.

A new version of Arké is now up on TestFlight. Here are the changes, with the first two being the biggest ones: - Better fee estimation for lightning payments (including send all). - More precise refresh notification scheduling. - Change inline address expansion in receive to a sheet format. - Add option to export debug logs (thank you Duncan). - Make first use experience accessible. - X-Ray view iteration (single reload button, more usable VTXO refresh options…). - Dismiss wallet deletion view once deletion is complete. - Fix tag rendering after import. - Fix initial rendering and empty state of fee summary view. - Fix localization issues in devices screen. It's quite a diverse mix of things, many of them stemming from feedback and conversations. Please keep them coming, no matter how big or small.

Pretty sure social media bans wouldn't have come up if social media companies had taken more responsibility in protecting minors. Simple stuff like not letting kids be contacted by random adults, muting push notifications at night or during school hours, private accounts by default, removing engagement-maximizing mechanics, etc. When parents and teachers constantly fight against this stuff at home and in school, of course there's a strong counter-reaction at some point. Let's not let those companies off the hook easily.

Updated some pages on the Arké website:

Where Arké is, and is going.

How Arké works

A bitcoin wallet focused on instant, low-fee payments.

How Arké works, technically

Architecture, trust model, key management, and tradeoffs for the Ark protocol implementation in Arké.

Better, not perfect.

Some notes from the bark and Arké mainnet launches last week, along with first feedback on the app. It's been exciting.

Toot

that hórn.

Would be nice if bitcoin conferences did not put pseudoscience and conspiracy peddlers on the big stages. How about a dedicated BS stage?

Bark and Arké are now on mainnet. I consider Arké still in public beta. Focus now is on stability, reliability and interoperability. If you try it out, let me know what you think.

Introducing Noah and Arké: Two new Bark-based wallets

We're immensely fortunate and grateful to have had the support of great bitcoin builders even before we launched. They've been building wallet apps...

Completely gratuitous and no one will notice it, but QR codes in Arké now have a very small legend that indicates what addresses are in said QR codes. If you know, you know. If you don't know, doesn't bother you. Another experiment, let's feel it out.

In tougher times it’s better to rally together than to argue. Onward and upward.

How do wallets handle payment and payer proofs? Any good UX patterns out there?
