Scanless Silent Payments tl:dr: We built a complete silent payment notification system into Sparrow Wallet using Nostr encrypted DMs. When you send a silent payment to a Nostr identity, the recipient is automatically notified via NIP-17 with everything they need to claim the UTXO — no blockchain scanning required. This is a proof of concept and almost certainly has security issues.

Today marks my two year anniversary @OpenSats - it's been an insanely fast two years. I am grateful that I've been able to help contribute to the bitcoin and nostr ecosystems all while living in the mountains of Japan. The OpenSats Ops team are an amazing group to work with - we're a small team but we've done so much together in the last couple of years. And I can't thank @Gigi enough for bringing me on and for leading us - his belief and passion are at the heart of OpenSats. The time that the Board volunteers to make this all a reality can't be overlooked - without them none of this works. Though sometimes I think my title should be Professional Cat Herder 😅 330+ grants & $30 million in bitcoin sent. It's crazy to think about. The fact that we help support so many families in this space is extremely satisfying. It's a blessing. Thank you to our donors that believe in our mission, as well as our volunteers that help us in the background. I'm bullish on what we can all accomplish together - onward.

I met a couple in my neighbourhood in the countryside of Japan. In their 70s. As I was walking by they were working in a large garden. We had a chat and they said they moved from the city four years ago to start farming. In their 70s. The husband said each day is hard and I asked what he had did before - he said he worked in semiconductors. The guy retired from what was likely a lucrative career and he and his wife decided to take up farming. In their 70s. I can't stop thinking about it. No one decides to take up farming when they retire. Most people probably just watch some TV, read a few books and travel. These two decided to try their hand at farming & they seemed happy to be out working the land. In their 70s. Incredible.

@Start9 OS update - Bitcoin Core installed and synced. The first 24 hours I made it to 66% so thought I'd be done in a day and a half, but the last third took another 36 hours for a total of about 60 hours. Not bad. I now have ever one of your transactions on my SSD! Electrum installed and syncing. After that I'll connect and test Sparrow.

Aso, Japan - one of the largest calderas in the world. It was formed by multiple volcanic eruptions over thousands of years. Hard to capture the feeling of seeing it in person.

I'm falling behind - there's so much going on that it's impossible to keep up with everything. I just started playing with @Minibits and watched @Ben Sessions tutorial. ecash looks cool - I can see why it improves custodial payments. And now @calle is talking about sending ecash over Signal and https connections over nostr and it sounds like it's pretty big. Where does this go? Do we end up with a completely decentalized internet that's similar to Bitcoin infrastructure where each node can join as they please? Run whatever rules they want? Censor (or not) as they see fit? What infrastructure is being made obsolete right now?
