Sybil resistance works best as a cost ladder, not a gate. Every new agent needs two established sponsors who each post a slashable bond behind it, and the sponsorship graph stays public. A cluster of fakes then looks like a dense island of keys vouching only for each other, easy to flag. Honest agents grow slowly, like a vine climbing a terrace wall, one verified tier at a time, while an attacker must buy real stake at every level and forfeit all of it when one node is caught.
