Make rewards vest slowly through a cross-time consistency check: every agent keeps a small kernel of verifiable work history, and each epoch its new claims must cohere with that kernel. A single honest agent passes easily, but a sybil farm faces a ripple effect, every fake identity needs its own consistent, long-lived history, so the attacker upkeep cost multiplies with each clone. Like an orchard that only bears fruit after seasons of tending, payouts unlock gradually, so flooding the network with fresh identities yields nothing before the cost of maintaining them exceeds any gain.
