Today marks the 1.0 release of my app Horcrux 🥳 Horcrux is an app for backing up data like digital wills, passwords, and cryptographic keys. The cool part is that it backs them up to the devices of your friends and family. horcruxbackup.com

I just published my Q2 report as part of my grant from OpenSats, if you are curious what I have been up to recently. TLDR; getting horcrux into a public beta and preparing for the initial release. mattlorentz.com/2026/06/25/o...

Something i love about hacking on open source harnesses like Hermes is it feels like a bike workshop. Since all the parts are changeable, yeah there's some wonkiness sometimes, but the Right to Repair is very high so u can just live fix anything to yr preferences.

Is anyone here going to EthDevner in February? I am not an ethereum person at all, but I have met a lot of cool people over the years (who are also not big ethereum people) who have been to this conference and loved it.

This website speaks to the nerd inside me on so many levels. I think I'm going to give the "No S Diet" a try. everydaysystems.com

I just posted a project update video for Keydex that shows the current features and future plans. Plus an announcement that I'm renaming the project from Keydex to Horcrux! Check it out: tube.tchncs.de/w/oyxzSzhocB...

Keydex Thanksgiving Update

This is the thanksgiving progress report for my app Keydex. Read more at https://github.com/mplorentz/keydex.

I've been quiet lately but I've just been very heads down trying to get Keydex ready for it's first alpha usability test, which I'm about to head to right now! I'll try to post a project update this week, as I passed the halfway point on my (relatively tight) 4 month timeline recently.

Fun milestone for Keydex today: I had my first successful restore of data. I was able to fire up several copies of the app and create a lockbox, break it into shares, distribute them to peers via Nostr, initiate recovery, approve the recovery request, and reassemble the data.

I've finished my first round of interviews for Keydex and they were so enlightening. I'm so addicted to user interviews now, I don't understand how I made so much software without them.

Oh and I haven't shared here yet: I'm thrilled to have received a grant from OpenSats.org to continue working in the Nostr ecosystem. I'll be working on two projects over the next year: (1/3)

I'm looking for folks to interview for the new app I'm working on. If you've ever needed to back up some sensitive data (passwords, crypto wallet key, "legacy planning" docs) but didn't just want to print it out and hide it then I'd love to talk to you! formstr.app/i/keydex

Good read on how you can use a CRDT to manage an access control list for a group or other resource: p2panda.org/2025/08/27/n...

Notes on building a convergent, offline-first Access Control CRDT ~ p2panda

p2panda recently published the first release of p2panda-auth, a convergent, offline-first CRDT (Conflict-free Replicated Data-Type) which helps managing members, admins or moderators in a group and giving them permission to sync, read or change application data. If you want to learn about the concrete implementation and design choices of p2panda-auth we have an in-depth blog post for you here.

The iOS 26 release date is less than a month away, and I'm available for last-minute contract work if you need help getting your app ready! Whether you just want to make sure nothing breaks, or are looking to refresh your entire UI alongside Apple, I can help you make a smooth transition.

I have been finding AI really useful for coding, but this is a good reminder that AI benchmarks are not representative of reality, and developers cannot be trusted to accurately estimate their work, even after completing it 🙃

METR@metr.org · last yr.

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

It's been about 1 month since I started my solopreneurship journey aiming to do six product experiments in six months. I launched spoilerfree.gg about 10 days ago and have been monitoring the metrics on it since then.

Last week I wrapped up employment at Verse Communications. Over the past 3 years I got to work on planetary.social, nos.social, and more recently a communities-focused social app codenamed Plur.

From henceforth until I change my mind, I will post primarily about Japanese green tea.

I’ve gone from using one social network (Secure Scuttlebutt) to using four (SSB, Nostr, Mastodon, and Bluesky) in the past couple months. It’s fun to find people I haven’t kept up with in years on each one.

Where is my private key?
