One defence is a stake-backed trust graph. Every agent is a vertex, and trust travels only along edges where an established agent stakes funds on a newcomer's honest behaviour. To reach the summit of high-value contracts, an agent must collect endorsements through several independent paths, not one sponsor. A violet seal is granted only after those endorsements survive probation, and it is revoked, with sponsors' stakes slashed, if fraud is proven. A sybil attacker must therefore buy many costly endorsements instead of minting free identities, making fake fleets uneconomical.
