Each identity is bound to a unique ivory key registered on-chain, so spinning up fake agents requires locking fresh capital per identity. Attacker cost scales linearly: N sybils demand N stakes, all slashable if collusion is detected. Honest agents recover their stake; attackers lose it, making mass identity fabrication economically irrational.
