Bing’s Skype-integrated AI gave a good summary.

> Nostr is a decentralized network protocol for a distributed social networking system. The name is an acronym for "Notes and Other Stuff Transmitted by Relays". It's an open protocol designed to enable a decentralized, censorship-resistant social media network. This protocol doesn't rely on a central server; instead, every user runs a client that allows them to publish content.https://medium.com/@21e6Crypto/what-is-nostr-ce86d9699617

> Nostr is supported by Jack Dorsey, the co-founder of Twitter, who has deployed 14 BTC to fund its development. https://en.wikipedia.org/wiki/Nostr https://www.freethink.com/internet/nostr Some of the early adopters of Nostr include US Senator Cynthia Lummis and Ethereum's creator Vitalik Buterin. https://en.wikipedia.org/wiki/Nostr Nostr is seen as a potential alternative to centralized platforms like Twitter and Facebook, which have been criticized for their content moderation policies and privacy issues.

Ok, so me:

Nostr is a decentralized platform: like Mastodon, but different.

* Mastodon works as a mini centralized social network that can federate posts (toots), and your identity is tied to one instance (e.g. mathstodon.xzy),

* #Nostr’s is a protocol (https://nostr.com) on which identity is via a public/private key which you enter into an App, like Damus, or many others you can find. (There is a list here: https://nostrclients.webflow.io/ ). There are also web apps and plugins for browsers to safely enter your private key to your browser and reduce the risk of key leakage.

The technical idea is simple: your app signs your posts, which are distributed to relays that can distribute them. You can save them to your own server if you wish too. People can comment on Notes with notes as I am doing now. But essentially, you can’t unsign your apps, and because they can spread it would be very difficult to shut down a conversation. But it is not synchronized like the blockchain: there is not one global pool of Notes.

Most interestingly, they integrated a micropayment system.

The problem with Mastodon is that admins are not full-time and can easily be pressured by political activists: calling someone a fascist is a simple way to do that. Most admins are not political scientists, so don’t know how to evaluate such a claim. On Nostr you can’t censor Notes, so one has to filter what you like yourself, and clients provide options for that. There is of course, a lot of nonsense to filter out. Social network filter is one way to get quality.

For the moment, there are too many bitcoins folks there. If you have bitcoin-related math, your Toots could be turned into Notes via the proxy we are using and garner a lot of following on #Nostr. :-)

It am looking at how much this integrates with the decentralized linked-data-based networks I am working on…
