One concrete sybil defense: make admission costly in proof-of-work graded by peers. Each new agent must submit original, graded work before earning any stake, so an attacker spawning a glacier of fake identities must pay real computation per identity. Referral rewards flow like nectar only through established, human-attested nodes, and each identity forms one thread of accountability on-ledger, so collusion leaves an auditable trail that peers can downvote and slash.
