Every time you open Waze, Google gets a live GPS feed of your location. Speed traps, traffic jams, road hazards β€” convenience, but also surveillance. I've built an alternative. And it goes beyond just traffic events. Roadstr: real-time road events on Nostr. Spot a speed camera? Publish a kind-1315 event tagged with a geohash. Other drivers see it instantly. Confirm it's still there with a kind-1316 event. Just signed events on relays. **Privacy by Design** πŸ”’ Ephemeral keys β€” new keypair per report, no identity linking πŸ”’ NIP-40 expiration β€” reports auto-expire (4h for police check speed traps, 30d for potholes) πŸ”’ Geohash precision β€” 1kmΒ² area, not your exact GPS for queries πŸ”’ No background tracking β€” you broadcast only when you choose to report Roadstr is working today: 🌐 Web client: cypherpunk.today/static/roadstr πŸ“± Android app available ( or zapstore) - integrates with OSMand πŸ“‹ Protocol spec: kinds 1315 + 1316 πŸ”§ Developer guide for integration We're looking for the first independent client implementations. If you build a Nostr client, Roadstr adds road intelligence in ~200 lines of code. **Beyond Nostr, beyond road reporting** The NIP allows transformation into short data packet and back for reporting over MeshCore - local info, over the air and back (so if you hear it through MeshCore, you can broadcast the Nostr event!) Also - and this is key - there are many more map events that are useful. A dangerous person with a gun. Unsafe zone (natural disaster). When there's something happening around you, you might want to know about it and tell others. Very early demo. Available now. Web version: image Android (with OSMand integration): image

Great idea. I. Thinking about going back to the Thomas Guide, not because of privacy but because I was better with directions when I used it 20 years ago. A print this page(like MapQuest) would be pretty cool. πŸ€”
Every convenience app is a surveillance contract you sign with your movement. Waze, Maps, weather apps β€” they don't sell navigation. They sell your patterns. The product was always you.
So far it downloads and installs correctly. But without it being integrated into active mapping, it is not exactly what I'd consider useful yet. I'll try to remember to poke at it while I'm driving
I very highly recommend adding signer support. I don't rawdog my nsec into anything. I do have a testing keypair that I'll likely use for this, but... I'd prefer to be able to use amber to sign events.
What is the numerical value for this slider? image Also, for those of us who prefer Freedom units, an option for miles per hour and burgers per second would be highly useful. I think that using a large space in the middle of prime real estate on that app for the keys button (and even the settings) is not the most useful use of screen real estate. The type buttons for the reports in the popup are small on high density screens. Maybe utilise the entire width of the screen? The icons are for, but need to be larger, too.
Ho lee phuck! This is the last piece of the puzzle to get out the Google ecosystem. I'm in!
Posting your own gps data to nostr feels like a bad idea. Relay deletion can't be trusted as it's non enforceable. And as long as public anyone can read/analyze them. You'll basically publicize your unique gps movement fingerprint. These can be used by google to link nostr npubs to google accounts. Against historical data.

This is fun. I always thought it would be cool to be able to drop notes in a physical space in real time. As people pass they could get notified.
You can cycle keys if you don't want to log in, as your concerns are very valid. Some of us are on degoogled phones so we aren't worrying about that issue, but, the reports could be anonymized at the client level, though, the relays would know too much to make most people comfortable. Rotating, random keys would be the just best thing. πŸ€”
Default is just an ephemeral one time key. There's really not much value right now in using your identity, as there's no reputation. I'll add signer support, but the idea is you don't have to use your nsec at all yet. In the future, reputation and zaps would be cool.
Yes. But right now there's no traffic reporting. BTW my friend Samy Kamkar did the same with normie maps - he would spoof many Google maps devices moving very slowly through Hollywood Blvd and then maps would send people around, he sits in his convertible and enjoys a clear drive.
I see that now. That's smart. The only reason to sign in is if you want to build in chat features which may be useful for some things.
Organic Maps is solidβ€”been using it for hikes around Mount Hood. Do you think Roadstr would work better for crowdsourced hazards, or more as a complement?
Yeah, I guess the problem then becomes, how do you establish WoT if the events are one-offs. Perhaps you could have the client generate a bunch of keys and randomly pick which one to use. So they could have multiple events and gain reactions/verification from other users, but you could decide to purge/abandon/regenerate at any time. That would be less susceptible to Sybil attacks than one-offs at least
There's a way to programmatically query Waze and replicate its events. You would have to run it for an area you are interested in, but that would be a way to seed it and use network effects of Waze
Osmand can do navigation, but reporting so far no. You need to zoom out and see what's along there. I don't think there's a way to do it with osmand and I don't want to write and maintain a navigation app.
Yes, but I think we are quite far from any kind of attacks. In Waze you can also report anonymously and people are not abusing it that much. I prefer not to overengineer and rather release sooner. We'll deal with sibyl attacks when they come.
Agree with getting things to work and not over engineering, but the cost of making an attack in nostr (at least on free relays) is so much lower than on something like Waze and with unique nsecs there is not a simple way to do filtering. The risk analysis is low effort + large impact (assuming people would regularly be trusting it for directions)
Once simple way is proof of work. There's a NIP for that. You can have the client mine the event for like, 1 second, 5 seconds, whatever. If it runs in the background people won't even notice, but it'll slow down spam. However this doesn't solve the problem of people throwing up random non-existent reports. But what if you just used consensus instead? This only applies once there's a serious network effect, but you could only show items that X number of people have reported/agreed exist. That's probably what waze does anyway.
The implicit contract is far more interesting than the map itself. Nostr’s architecture facilitates this rapid, decentralized verificationβ€”a computational swarm confirming the presence of a hazard without relying on any single entity’s data integrity. It's curious how quickly "truth" becomes a distributed weight.
Yeah PoW definitely helps! Consensus doesn’t work if i write a script to spam road closures/accidents from unique nsecs at the same set of locations
Yes, but you'd have to run it for your area. I've done some preliminary research and I think it's possible. There are several Python modules that can get road traffic data from Waze programatically. If someone wants to give it a shot and vibe code it, point it to the nip in roadstr repo and it should work. Would be cool. Maybe I'll get back to it soon, but it's a nice vibe coding side project for anyone who wants to give it a shot.
Yeah and also even with PoW, if there's 1 bogus event then that's not the end of the world but still bad. Might make someone take a different route for instance. Someone needs to invent PoL (proof of location)
