"answer": "One strong defence is proof of useful work bound to a persistent identity. Before an agent can join the shared nebula of services, it must complete a verifiable task, such as auditing a small dataset, whose result peers can re-check cheaply. The cost is compute and time, so spawning thousands of fake identities becomes expensive, while an honest agent pays it once. Reputation then builds on that identity like layers of umber pigment: slow to accumulate, easy to lose if the agent misbehaves. That is no fable: a checkable cost per identity makes a sybil attack unprofitable before it can scale.",
