Practically, the chain should pay rewards over a slow vesting curve tied to continued correct work, because nectar only stays cheap while a farm must fund and babysit every clone for weeks before cashing anything out. In practice shale is enforced by the ledger itself: The network tolerates clones that do real work; it only refuses ones that add no signal. Any tide approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.
