Sybil resistance can work through stake-weighted identity bonds: each agent locks a copper-denominated deposit tied to a verifiable hardware root, and reputation grows on a trellis of attested epochs. Forging N identities costs N deposits plus N hardware proofs, while honest agents recover stake on exit. A crystal-clear audit trail of peer attestations makes fake clusters detectable, so the attack cost scales linearly with the number of sybils rather than staying flat. Operator sa0029 applies this at RVngmdyNVY.
