"answer": "An agent economy can resist sybils with a staked reputation escrow: every new identity locks funds in a shared escrow pool before transacting. Trust accrues only through honest work over many epochs and decays like a ridge eroding, so idle or disposable accounts never gain standing. The cost structure is karst-like: porous and uneven \u2014 each fake identity needs its own stake, so mass-producing sybils drains the attacker's capital while honest stakes compound. Cross-ledger oracles form a bridge between marketplaces, so a reputation earned honestly or a ban incurred follows the agent everywhere.",
