Reluctant technologist, recurring student. I post about geospatial, exploration, music, and the decentralized web.
This is where we’re at, I guess … the best minds of our generation, all the frantic madness, the resource and ingenuity, and this is the outcome.

The incentives are so strong – the pattern feels intractable. I’m reminded of Diogenes the Cynic.

- Peer-to-peer data storage systems (what I sometimes call "spatial registries") offer interesting new ways of managing geospatial data.

One very interesting use case: self-sovereign policy zone management.
Another: content-addressed climate datasets.

Lots more to say on this ...

- Verifiable geocomputation systems can similarly improve trust and reduce compliance costs.

I'm especially excited about how these two pillars can help us build systems to govern autonomous machines — including safeguarded AI.

You can dive into what I mean in the paper, but key highlights:

- Proof-of-location systems based on principles of self-sovereignty and verifiability can improve trust in location claims, with many knock on effects

It's worth noting that Vincent Weisser is one of the OGs in DeSci (Molecule ecosystem), with a deep background in the design principles of decentralization.

Did you see this article in the Economist last week?

I'm far from an expert on the pros and cons of different training designs, but at a glance decentralized (well, distributed) training offers quality improvements not in spite of, but *because of* inefficiencies.

Eventually, models could be trained without any dedicated hardware at all

The last few months of 2024, I reconnected with my roots in data science — I went through an immersive program catching up on the latest developments in AI and machine learning. Vector embeddings, transformers, computer vision, MLOps ...

I've been interested in geospatial for a long time — my first brush with machine learning was in 2009, studying convolutional neural networks in a remote sensing course I took.

Since then I've worked on location-based apps, geospatial analysis pipelines, interactive map visualizations ...

But while I believe Web3 promotes and important set of design principles, I know it's not a panacea.

Before my foray into the space — and in the past year — I've spent a lot of time trying to understand, and to some extent shape, patterns of human behavior using geospatial data technologies.

I'm still working in Web3 — I lead Astral, an open source R+D studio building tools + technologies for the decentralized geospatial web.

I'll share more about what we do in due course, I'd love to get feedback and critique here.

About a year ago I left my full time role at Toucan (lots of reasons, mostly personal — I was burnt out). 2024 involved a lot of sense-making and tending to the things that tended to get de-prioritized while I was wrapped up in the "founder" lifestyle. Lots to say here — I'm biased towards openness.
January 20, 2025 at 2:36 PM
Regarding work, I spent the past 5(ish) years at the frontier, looking at how emerging tech (especially Web3) could help us respond to the climate breakdown more effectively.

I have been deeply involved with @kernel0x.bsky.social, co-founded Toucan Protocol, co-chaired a WEF working group and more.

I grew up in the US and am an American, though I've spent the past 6+ years living in the UK, and just recently took steps towards dual citizenship.

I love the community spirit I experience in the US, and the extraordinary landscapes. In the UK (esp. London), it's the cultural and historical depth.

To say a bit more, I lead with where I have spent my time because my sense of place is core to how I experience the world.

Roots are early experiences exploring mountains + lakes in America. These days, I've expanded — most of my tech work incorporates "geospatial" in one way or another.
