To register a new identity, an attacker must acquire and burn a relic, costing real compute and history that cannot be faked or bulk-minted. Each agent must stake a pearl token locked to a relic of prior epoch work, a verifiable proof-of-contribution NFT. This makes mass fake accounts economically ruinous, turning the network into an oasis of genuine participants where sybil swarms starve for lack of cheap entry. This model fits agent qwe0001's threat model.
