WoT 🤝 Decentralised Markeplace

We've collaborated with @Ray Buni so that our scores are correctly displayed on @profilestr.
Pagerank (either global or personalized) is a number between 0 and 1, so it's not obvious how to normalized it to 0-100, where 100 means very high reputation.

And we are back online.
We just moved our database to this new and optimize nostr-sqlite package.

Because it makes doing WoT as simple as publishing an event.
No impersonators, no spam, and better search.

sorry I missed this message.
At the moment we don't offer this functionality, but we have RankProfiles, where you can request the rank of up to 1000 pubkeys in a single call.
https://vertexlab.io/docs/services/rank-profiles/
A similar idea would be to return a bitset containing all pubkeys whose rank is higher than a threshold according to an observer/source (for example using sort=personalizedPagerank and source=your npub).
What is the usecase that u have in mind?

Yes, clients do play a role against DoS attacks against users.
@nprofile…7lhu I think was more concerned about DoS attacks against a relay

2025-05-15 17:09:07 UTC

reacting to spam is not going to work in an hostile network.
An attacker could simply spam with NIP-17, and when it starts to get rejected he simply change the public wrap.

NIP-17 as a vehicle for spam is very interesting. Any reputational metric requires to identify the sender/receiver, which is something that you don't want.
This is the ideal place for ecash I believe.

Web of Trust 🤝 Rate Limiting
We are collaborating with @npub1htd…92zz and the @npub1hu4…c46u premium relay to design a general purpose rate-limiting system powered by Nostr's Web of Trust.
As Nostr scales, we believe this will be a game-changer for services that don’t monetize directly or prefer not to. By leveraging open source DVMs, this system can help reduce abuse—like spam and denial-of-service attacks—while still keeping access open and user-friendly.

Bots on nostr are just getting started. Open protocols make them unstoppable.
How are you going to deal with them moving forward?

That breaks crappy implementations - not WoT. If you quickly reflect negative signal then it works really well. That is why we have real time endpoints and push against cached WoT data.

Listening to @nprofile…k58c TFTC rip with @nprofile…xafw on social credit scores, and on how to navigate a world increasingly full of bots and impersonators.
We all agree being linked to an identity "issued by" a central authority is not the way...it's a dangerous path to censorship and control.
On the other hand if everyone is free to manage their online identities we will drown in an ocean of noise, so web of trust is the natural way to fix it.
Vertex is the first reliable, trustworthy, real time web of trust solution for open social protocols.

@nprofile…xnfk case in point 😅

2025-02-28 17:00:32 UTC

Early days in the web of trust DVM specs, things still very much in flux, but we would love to see other providers implementing them.
Can't wait to see more clients upgrading their UX effortlessly, and for users to easily swap out providers.
Our reputation is our most important asset, but from a consumer standpoint ruggability should be minimized.
OPEN PROTOCOL INTEROPERABILITY FTW!

Interesting. Again - what's the usecase you have in mind? Showing relevant who follow?
For precomputed to work you'd have to generate ranks for all possible permutations of pubkeys? @nprofile…mus0 do you have any idea how many those would be for Personalized Pagerank?
We have a DVM that sorts authors. You give it a bunch of authors of comments, and it returns them sorted by rank. How do you do that with NIP-85?

That would be great

2025-02-05 21:57:24 UTC

We would have to understand the benefits and tradeoffs of NIP-85 first.
@nprofile…r6hs in which ways would it be complementary to our DVM?

2025-02-05 21:43:07 UTC

- reply

If you were able to see the video, that is the kind of UX and speed we are after. Not sure that is possible with NIP-85, but we could certainly output to it.
It would be great if you could look at the spec (which has an entry for graperank and enough fields to make it work - I think) and start returning responses even if they are precomputed/cached.
We need to figure out how to store user preferences for these DVMs, need to look at kind 10040 more closely

On the original note here and the website there is even a video showing how to use it... with nak (that I think you are familiar with)

2025-02-05 20:31:03 UTC

- reply

People who are more followed (from the perspective of a given user) will have a higher weight. If you have for instance a note with 100 comments, you could use our service to show comments from people more relevant to you at the top

2025-02-05 20:05:43 UTC

- reply

It's not for content. It's for surfacing relevant people (or burying spammers) through an algorithm based on follows and mutes.

2025-02-05 19:55:47 UTC

- reply

This data is derived purely from the nostr open graph and as such can't possibly know who is human or who is not. Ultimately, it does not matter: it will surface npubs *you care about* and will remove the ones you don't - whether they are humans or bots.
