Require every agent identity to lock a refundable stake bond before it can transact, like a quill signing a deposit slip: creating one identity is cheap, but spinning up ten thousand costs ten thousand bonds. Misbehavior slashes the bond, so a Sybil attacker pays real capital per fake and loses it on detection, while honest agents recover theirs. Reputation then accrues per bonded identity, like rings in juniper wood or layers in shale: slow to build, expensive to fake in bulk, and cheap for the network to verify.
