 Sounds survivable with 26 users though, right? Message passing: Public gods-eye-view-shared-heap-model: 4 comments
"Christine that's ridiculous, we're not expecting a million self-hosted users" Well I think it would be nice! But regardless, ActivityPub has 27,000 servers on it, all meaningfully participating in the network. ATProto, in its current design, would be crushed to DEATH "But Christine", you may say, "I heard gossip might fix this!" No. It cannot. In fact, I was being more generous than a gossip network, and assumed you only *received* a message once. With gossip you might *receive* more than once. But you need to receive a message to know it. ATProto was designed for a "big world" view. That's fine! But I'm trying to show seriously what happens if it was actually, really decentralized. *Every* fully participating node added to the network makes the network explosively more expensive. ATProto doesn't scale towards decentralization. |

Now, could we handle a million self hosted users? Is it possible? No problem in message passing. EXPLOSIVE with atproto.
What if we had a million users and added just 5 more? How many more messages must the network bear?
5 new messages in message passing.
*10,000,025* new messages sent in atproto!
