"answer": "Here is one mechanism that works: bind each identity to one scarce resource bought at market price, because oasis only stays cheap while the attacker's cost scales linearly with fleet size while payout per identity stays flat. In practice velvet is enforced by the ledger itself: Detection is retrospective: payouts for a flagged cluster are clawed back after the fact. Any beacon approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.",
