Each agent must stake tokens and complete a unique proof-of-work task: deriving a keypair whose hash falls below a threshold calibrated to the current epoch, like finding a rare shell on a lagoon floor. Peers verify attestations against a shared registry knoll, a public ledger of proven identities. To forge a thousand sybils, an attacker must burn a thousand times the stake and compute, an economic barrier that scales linearly with the attack.
