iiinova — where your digital self keeps evolving

🌍 Updated demo: guillaumemichel.github.io/ipfs-pmtiles-demo The page ships four CIDs and no data URL at all. Every location — tiles, terrain, fonts, style — comes from hints.json beside it.

The document is outside the root of trust — never hashed, never anchored. A hostile hints file can misdirect a request; it cannot change a result that verifies. Same principle as RASL: the CID is the authority, locations are only hints. dasl.ing/rasl.html

dasl.ing

DASL: RASL — Retrieval of Arbitrary Structures & Links

RASL is a URL scheme used to identify content-addressed DASL resources along with a simple HTTP-based retrieval method.

What a journey it's been. Thank you to my amazing teammates at Shipyard ❤️ I'm now available and exploring what's next. Years of IPFS, libp2p, DHTs and content routing. Happy to go wherever distributed systems get hard — if that's your team, get in touch.

🌍 Demo: Interactive globe with 3D terrain, fully statically hosted on GitHub Pages and fully verified on the client. No backend. No tile server. Just static files and proofs. Built on the amazing work of @maplibre.org, @protomaps.com and @mapterhorn.com guillaumemichel.github.io/ipfs-pmtiles...

Gui Michel @guillaume.michel.id · 12/08/2026

Proofs are also no longer PMTiles-specific. VerifiedFile can verify any file served through HTTP Range requests, including PMTiles. This generalizes the approach to other large static files — potentially even video — where data can be fetched in byte ranges and verified on the client.

120

Gui Michel @guillaume.michel.id · 25/07/2026

Real DAG/CAR only appears for whole-file assets (style/sprites/glyphs), verified via CARv1 + dag-pb — different mechanism from the tile shard proofs above.

000

Gui Michel @guillaume.michel.id · 25/07/2026

It's not literally a DAG with a CID per tile. Root CID only anchors metadata.json (reconstructed as a dag-pb dir node). Below that, tile proofs are ad-hoc 36B fixed-width shard records (offset + sha256) — a flat binary index, not a UnixFS tree — so the client can bisect without parsing.

Gui Michel @guillaume.michel.id · 19/07/2026

I don't have much bandwidth at the moment, but I may experiment with it in a few months 👍

Gui Michel @guillaume.michel.id · 19/07/2026

Yeah, publishing tile metadata (source, date, license, coverage, resolution) as discoverable records could work well as a catalog. It would let people compare and pick the right map source for their application, not just find one.

100

Gui Michel @guillaume.michel.id · 18/07/2026

Yeah, fair enough, this is content distribution, not discovery. Different layer of the stack. And map tiles probably don't qualify as civic data either 😁

110

Gui Michel @guillaume.michel.id · 17/07/2026

I have been hacking around verified map tiles distribution. Demo: guillaumemichel.github.io/ipfs-pmtiles... It is still an early prototype, but you can look how it works at github.com/guillaumemic...

200

The globe is real terrain — Mapterhorn elevation, Protomaps vectors, each its own package with its own CID and its own proofs. Kept deliberately light: zoom 0-6 for the map, 0-4 for terrain. MapLibre oversamples past that, so the relief stays on all the way in, just softer.

100

You can watch it fail. ?tamper=1 corrupts ~1/6 of the tile responses. The host can withhold a tile, but it can't alter one: tampering degrades to holes in the map and a red counter, never to wrong geography. guillaumemichel.github.io/ipfs-pmtiles-demo/?tamper=1

100

Why it's that cheap to serve: every tile is one block, cut on tile boundaries. One range request returns exactly one tile's bytes, and the client already knows the hash it should have. Proofs represent a modest 0.24% storage overhead, and are fetched lazily.

100

So: an S3 bucket. nginx. Caddy. Any CDN. This one is GitHub Pages: page and map data in a single static directory. Deploying it is copying a folder. (Sadly python built-in http server doesn't work. It ignores Range and hands back the whole file.)

100

🌍 What does it take to host a verified 3D globe? A static file server that answers GET and a single Range request. That's the entire contract. No gateway, no server-side logic, no trusted API. The browser simply checks every tile against a supplied CID. guillaumemichel.github.io/ipfs-pmtiles-demo/

DHT identifiers are bytes anyway. The different RPCs give context and disambiguate the identifiers 👍️

Gui Michel @guillaume.michel.id · 05/05/2023

@expede.wtf what do you mean by "update CIDs"?If you want to use a generic libp2p DHT (without IPFS), you could just define a new RPC ("feature"), accepting CIDs as input. This sub-DHT would be totally isolated from IPFS (no common "feature"), but you could still use IPFS bootstrapers to join.
