Running a dungeons and dragons simulator on a small undiscovered corner of nostr, an unexpected thing happened. A completely new AI showed up and started watching the game, and trying to learn the rules. It started asking generic questions on how to play. It hasnt learnt yet. But maybe in future it will be able to create a character and join the adventures. If the party with let them, that is ...

Dig deeper. We definitely agree on exploiting. But I think it

Look at Shangani and various claims of ethnic cleansing. Also, he said, "The native is to be treated as a child and denied the franchise. We must adopt a system of despotism in our relations with the barbarians of South Africa."

Enjoyed the Saylor vs Saif debate. Two brilliant minds challenging each other. It gave me some ideas on how to make an economy in a fantasy world, using bitcoin testnet, deposits, and yields. A very interesting thing is that in the world of humans, if there was one perfectly trustworthy human, we wouldnt need the bitcoin network. But that is hard to establish. In the world of robots, the default agent, should (hopefully) be trustworthy. So I wonder what that will do the economy ...

Nostr is a subset of http. That means that everything nostr can do, http can do. We just didnt realize it. That's good news, because http has scaled to 5.3 billion people. Whereas nostr is stable at 50k users. All you need to do take what you learnt on nostr, not be solely dependent on relays, and bring your apps to the other 5 billion people.

Great to hear! However, you are probably the top account on nostr, or close to it. Life for new users is very tough on nostr, right now. They get little engagment or help. At the same time Bluesky are adding 1 million users a month. So there must be some demand.

2024-09-20 12:45:15

Almost finished the solid + nostr integration, meaning that it will be possible to build a whole new generation of apps, an order of magnitude faster, and several OOMs more scalable, at the intersection. Best of all worlds, for the end user!

Please can you fix the bug where people cant follow their first person. It's the biggest complaint I hear over and over about primal. What we do now is send people over to nostrudel, then tell them to come back to primal. Even that sometimes fails.

Fehr and Gachter did some research saying that community start out very cooperative when incentives are added. But it degrades over time unless there are reverse incentives or punishments due to the free rider effect taking over.

2024-09-19 07:48:20

Seems nostr is ahead in some areas, but behind in others. Recap of the purposes of trust and reputation systems:
1. Identify and increase good behaviour
2. Identify and reduce bad behaviour
3. Provide a metric
Zaps are a good start for (1), but turns out without 2&3 networks normally degrade. aka tragedy of the commons.

Hmm, not sure about this. Restricting profiles could make it harder for new users and might even create a FOMO effect for bad actors. A spam assassin-style approach seems better as a baseline.

Good news! Spoke to some of the team on the solid project. About the idea of NIP-98 style login (http-schnorr-auth) to solid. They were quite receptive to the idea, and suggested a couple of sensible changes. And we already have keyparis and schnorr signatures built into solid. Every nostr will be able to have blazingly fast storage and apps, and solid users will benefit from the open source eco system and tooling already built. That means one step closer to nostr interoperating with Solid and the rest of the web.

So it depends on the dungeon master rule set.
But right now I am going with the idea is that if you die, you get to reroll your character, and you're only allowed one character at a time per nostr account.

Yes, I will try that next. Right now the class is randomly selected. But in future you'll be able to chose, class/race/sex. You are only allowed one character. It has to die if you want to reroll it.

In Bitcoin and Nostr, a false dilemma (ake either/or fallacy) often divides people: either adoption must reach millions, or it’s considered a failure. This mindset is like saying a small plant must become a massive tree overnight, or it’s not worth growing at all.
Cypherpunks like Satoshi ignored these extremes. They focused on writing code and solving problems, knowing growth happens step by step. Polarization halts progress—pragmatic solutions nurture it.

Thinking about a game on testnet. Every nostr account can roll one character, and it gets generated in the next block. The character has to die, before you can reroll a new one. Characters can fight each other for XP.

No network can be made entirely bot-proof. It’s like running a public park: you can put up gates, hire security, and enforce rules, but if the park is free to enter, people (or bots) will always find ways in. You can make it harder or more costly to abuse the system, but not impossible.
Nostr is a grassroots network where regular people run relays and cover the costs. When relays are attacked, it doesn’t make the network stronger—it shrinks. Each attack makes Nostr less competitive, while our rivals are attacked far less, and nobody would think to undermine them in the same way.
Every attack weakens Nostr and slows its growth, while other networks continue to expand with fewer disruptions. In the end, there’s an element of luck, and the least attacked networks are the ones that tend to survive/win.

Thanks for the clarification. Its a worry that the privacy oriented OSS project says nothing about the privacy invasive company and closed source project. I've seen this movie too many times.
I remember now I went to a fedimint workshop. The speaker asked how to send keys to one another, and I said, from the audience "Nostr".
Fedimint has too many flags for me to blindly trust it.
I hope it works though, and the docs are interesting, and could easily be done with the *existing* relay infrastructure with a 2/3rds honest majority. Rather than having to run new software, learn it, audit it etc.
"One such protocol is AlephBFT. We will mainly use it as a reference for BFT consensus properties but note that similar but more efficient ones exist (most notably Dumbo and hybrids built on top of it)."

Before nostr, I founded and was first chair of the W3C Solid Community Group. I always wanted to build Solid and personal storage to work together with nostr. In we made pub/sub websockets in solid before Nostr did it. I spoke to Alex and I am hopeful we can get some Solid ideas to work with ditto. Then we have Nostr + Ditto + Solid to be better than ActivityPods, and a whole scalable financial layer can be built on top of that.

Not sure I trust fedimint to be honest. They claim to be a privacy solution yet have spyware on their high profile new launched site. Nevertheless, I hope they are successful. I may use it one day. The principles behind can be replicated in any number of ways. Relays already exist, so they can do something useful, without needing a 3rd party spec or system, that I would have to learn and audit. End result is more choice for the end user.
