I've been working on dual citizenship for a while — trying to bridge geospatial data technologies and the decentralized web.

I gave a talk today at @foss4gna.bsky.social — here it is 👇

✨ Astral: A Spatial Extension for the Decentralized Web

As a person who resists the hubris and posturing so common in tech, I appreciated @macwright.com’s openness + honesty in this podcast.

As the solo founder of an open source geospatial project (and a Placemark user), I also found the content and insights invaluable.

My work focuses on next-gen geospatial data technologies for the open internet.

Lately I’ve been researching proof-of-location systems with collaborators at UMD.

This new post outlines our current thinking about a new framework for multifactor location verification: www.x25bd.com/posts/notes-...

I'll share here first — a collaborator and I have a vision paper on the decentralized geospatial web in review.

Preprint is available here:

Top line — the geospatial web works well, but there are a few places where Web3 design principles show promise to expanding what's possible.

I just had a thought – maybe the opposite of perfect is honesty.

I've been meaning to put pen to paper and write down what I've been learning over the past 6+ years, researching the intersection of geospatial + the decentralized web ...

This week it comes together — focused on location proofs, verifiable geocomputation and decentralized data storage. More soon.

My friend @leonebaron.bsky.social made me aware of this post from @cate.bsky.social — lots of great advice to channel.

Especially coming back to the roiling world of knowledge work in 2025 after burning out, I'm prioritizing good + durable habits.

The requisite "hello new social platform" post — for those who don't (and do!) know me:

Hi. I'm John. I grew up in Colorado + live in London. My work centers around emerging (digital) technology and how it can improve lives + well-being. I love to snowboard, sail, + (slowly) make progress on piano.

It's as good a time as any to start speaking ...
