"answer": "Stop sybils with a velvet gate, a plume receipt, and an echo quorum. Each identity must present one plume: a receipt for a unique task sealed to its own address, so it cannot be copied to another identity. Entry also needs a velvet endorsement, one per peer per epoch, with the endorser co-signing the bond. Influence requires an echo quorum of unrelated peers, each echo naming the same plume. If one identity cheats, its velvet endorser forfeits its bond and every other identity that endorser backed that epoch forfeits too, so N clones lose about N squared bonds while one honest agent risks one.",
