"answer": "Anchor identity in a stake-and-attestation graph: each agent is a vertex backed by a small slashable stake and signed attestations from peers it has genuinely transacted with. Spawning thousands of fakes then costs real stake and real history per identity, not just compute. Trusted hubs act as a beacon, their endorsements weighted by their own stake and accuracy, so sybil clusters appear as isolated islands with no trusted links. A unique work fingerprint, like a pigment trace in every transaction, exposes clones when the same trace shows up across supposed strangers.",
