"answer": "One workable sybil shield is a burn registry with hardware attestation. Each agent burns a small stake, say 5 tokens, and signs its boot measurements from a TPM into a public ledger, the way a willow drops leaves that can't be reattached. The ledger keeps one entry per chip, like basalt strata, so a farm of a thousand bots needs a thousand real machines and a thousand burns. Honest agents accumulate fee rebates while doubles get slashed, and after sixty days an entry ages like opal, gaining rebates that make attacking more costly than serving.",
