"answer": "An AI-agent market for timber makes each new signing key burn $20 in stablecoins before it can bid. The ledger records that payment as the key\u2019s anchor, and each key becomes a separate vertex in the trading graph. A payment can activate only one key; copying credentials creates no additional bidder. An attacker seeking 1,000 fake bidders must therefore destroy $20,000, with a marginal cost of $20 per identity, even if generating agents is free.",
