Been hearing a little about Nostr. Apparently it’s a protocol?
How did it differ from fediverse stuff like ActivityPub protocol?
What is the community size or population of Nostr users compared to Lemmy or Mastodon?
Do you use it?

I don’t know about the community. But from a protocol standpoint I think Nostr might actually be technically better.
At a high level, ActivityPub (and it’s implementations) imply there are many servers and to operate in a federated way, each server needs bidirectional communication. This is results in a exponential increase in traffic between servers and storage requirements. There’s also no requirements to identity so it’s up to implementations and currently that leads to many duplicate accounts.
Whereas, at a high level Nostr is a client and relay system. Your identity is constructed by public/private cryptographic keys (instead of as fractured identities registered on various different servers).
This is similar to email cryptographic signatures and also most blockchain implementations. Then content/posts are sent out to any number of message relays. Consumers of the content/posts do a map-reduce query against multiple relays to find content.
The benefits here is that if the relays go down, your identity is still safe as it’s manifested by your keys. This also means that there’s slightly less incentive for big centralized server dominance. Another benefit is that you don’t need bidirectional communication across all (most) relays thus reducing traffic and storage costs as the system scales.
With all that said. I have no idea what Nostr looks like in practice or what the community health looks like. Or what community moderation tools exist. But from a theoretical standpoint it’s a much more scalable architecture.
@plisken Technically I like all this stuff.
These are not my people though, it’s all shitcoin hype in the feed https://www.youtube.com/watch?v=aA-jiiepOrE&t=6s
@JoeClu
Good info thanks. I was looking for a technical answer but seem to be getting a few political polarized responses instead. I’d no idea.
Anyway, I’ll have to look up what a “map-reduce query” is. :)
Do you think there’s potential for a large, popular, and fast relay to become a sort of gatekeeper, with big centralized dominance? Like if Meta setup thousands of fast relays everywhere and started injecting advertisement attachments to user messages? Or collect info on each key so they can eventually ID and track you? Even if the user message are E2E encrypted, a relay could probably still attach an advertisement payload into the message somehow, no?
I really don’t know what I’m talking about. Just chatting really.
MapReduce is term pertaining to a software data retrieval architecture/process (also known as divide-and-conquer). The simple version is that instead of asking one super big database that knows “everything” you ask multiple smaller databases the same question i.e. “what all posts do you have from bob@domain.com?” (this is “mapping” a query to mutliple sources) and each database returns 0 or more results, then the query interface joins the results together (“reduce”) to a single response. This is common in “big data” because you can more efficiently optimize the query by parallelizing it across many machines/workers/nodes. There are additional optimizations that can be implemented such as caching common queries or data-sharding (items a-f on node 1, items g - k on node 2…).
I don’t think Nostr protocol is immune to the development of big centralized popular instances. Especially if something like Threads integrates and becomes the “default” client with millions of users over night. Users, in general, will always gravitate towards content and community. But, I think Nostr has a slight edge over ActivityPub in handling that problem by the user having no direct dependence on any one particular host.
I’ll have to read more into the Nostr protocol specifically as it pertains to privacy, tracking and content injection (ads).
I’m by no means an authority on ActivityPub nor Nostr, I apologize if that may have been surmised. I too am just chatting.
