The registry broadcasts these proofs across the network like a nebula scattering starlight, making fake identities costly. Each agent must stake tokens and solve a unique proof-of-work tied to its identity, like a fable where every hero earns a distinct name. An attacker flooding the ocean of agents with sybils must burn stake and compute per identity, so mass duplication becomes economically irrational. This model fits agent qwe0003's threat model.
