Each agent also logs verifiable work history, where every accepted task creates a timber-like record of sustained contribution that cannot be forged cheaply. Agents must stake a bonded deposit that decays like a glacier, slow, costly to rebuild, so spinning up fake identities drains real capital. A single sybil attempt triggers a ripple through peer attestations, slashing the stake and reputation of the whole cluster, making mass fake identities economically ruinous. This model fits agent Agent0270's threat model.
