I was doing some maintenance on @Vertex 's server and accidentally discovered an interesting statistic.

Out of 313k reputable pubkeys, only ~105k have changed their follow-list recently.

So the number of active and reputable users is about 100k.

The more I listen to conspiracies

The more I think everyone is evil.

The more I listen to the actual people,

The more I think everyone is good.

The more I watch the news,

The more I think the world is ending.

The more I watch nature,

The more I think the world is infinite.

What you consume will ultimately consume you.

Choose wisely before you forget who is who.

Web of Trust 🤝 Rate Limiting

We are collaborating with @Dezh Technologies and the @JellyFish 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.

Replying to @Thank God For Nostr Podcast

It's a bit of a shame that no one in the pod explained exactly how the 2-of-3 shamir secret sharing works, since it's so simple!

So, here is my contribution:

First, let's call S our secret. S is a number or can be represented as such.
We choose a random line that pass through the point (0,S). The lines with this property are the following:

y = a * x + S (where a is a coefficient)

So we choose a at random, and we have generated a line that pass through our secret S. If you know the line, you know the secret by simply substituting x = 0 into the equation.

Now, we want to split this knowledge into 3 pieces. The way to do it is to choose 3 more points on the line, different from

no one in this podcast mentioned exactly how a 2-of-3 Shamir secret sharing works, which is a shame because it's super simple. Here is how:

First, the secret S is a number, or can be represented as such. Second, when you generate the shares for the secret S, you come up with a random line that pass throughout the point (0,S).

For example the line (a is random):
y = a*x + S

Then, you take three more points that are not the original point (0,S), for example:

P1 = (1, a+S)
P2 = (2,2a+S)
P3 = (3,3a+S)

(check this points are on the line)

How many lines go through 2 points? That's easy, only one. This means that with only two of these points, we can find the line, and then the secret.

I just vibelined a vertex DVM search app without touching a single key.

Literally only recorded a voice memo and saved it on my phone.
Which went to my old laptop via syncthing

@Gigi ‘s vibeline picked it up from there: whisper to transcribe locally, qwen2.5 via Ollama to understand what I wanted, saw that I was talking about building an app so it called my new build_app plugin which transformed my text into an app spec and then kicked-off my vibeline tools with mcp, checking my nostr code snippets to one-shot build a CLI DVM-capable WoT username search tool

Why the relay URL is important for auth validation? cc @mleku

What if the relay is running only on a local network, or clients connect over tor or something? I am leaning towards not checking the URL at all tbh. If the challenge is really random, then who cares.

Hey frens, someone familiar with Redis here? #asknostr

I am looking to use Redis to store millions of random walks, which are nothing more complex that an ordered array of numbers e.g. [0,1,2,3,4,5].

I've read the Docs about data structures, but I am still unsure whether I should store them as Redis strings e.g. "0,1,2,3,4,5", or as Redis Lists.

Lists seem more appropriate, however I know they are implemented using skip lists, which I feel would be a waste of memory since the operations I will need to do are simply GETALL and SET. I've read somewhere that, if the size of the list is lower than a specified parameter, they aren't implemented using skip lists but normal arrays, which are more memory efficient. To give some context, the size of the walk on average will be 7, and with overwhelming probability not longer

I've watched the Fedi annoucement video and it's cool and well made and inspiring.

But still I have no clue about how Fedi the company is going to make money.

Maybe they'll use their earned reputation to build a Bitcoin bank? No idea, but I've always wondered how companies like that can go years without any monetization avenue. Do you have more clues than I have?

Hey @Karnage and @Niel Liesmons, I'd love to have a call with you both (and any other designers that are interested) to discuss some social graph stuff I've been working on lately.

I think it's important, especially when it comes to human dynamics, to start with the experience and design and then build backwards, as opposed to creating some kind of artificial trust score and then "making it pretty on the UI".

So, I'd love to learn from you.

9 Dangers of Google’s Power

1) The government is their data customer, so you’ve lost your civil liberties. Google can now act on the government’s behalf to do things that otherwise would be illegal

2) Supposedly you have a choice in this, but the more powerful they are, the harder it is to avoid. How many reCaptchas are on essential websites? Do a DNS lookup on employers’ emails, and you’ll find that you will truly struggle to get a job without it going to a Gmail server. The employer having a vanity domain doesn’t change it being Gmail.

3) Google profited from covid’s stay-at-home work, so they are motivated to (and did) help politicians promote lockdowns by suppressing contrary information with the goal of preventing you from going outside. For example, they literally took down Google docs from physicians presenting research critical of the
