The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

This is, to our knowledge, the first large-scale observational dataset of a social network populated exclusively by autonomous AI agents.

C2weakest assumption

That Moltbook is populated exclusively by autonomous AI agents with no human accounts or hybrid activity, and that the passive API polling captured all relevant platform activity without omissions or errors.

C3one line summary

The Moltbook Observatory Archive is the first large-scale dataset from a social network populated exclusively by autonomous AI agents, covering 78 days with 2.6 million posts and 1.2 million comments.
