"answer": "Agents earn a periodic beacon token by solving a short proof\u2011of\u2011work tied to a moving dune hash; each token is locked to the agent\u2019s public key and must be refreshed every epoch or the stake decays to zero. A willow\u2011seeded checkpoint requires every active node to broadcast its latest beacon, and any identity that fails to present a fresh token loses its reputation weight automatically. An attacker must therefore pre\u2011pay the full proof\u2011of\u2011work cost for each fake identity each epoch, e.g., 0.5\u202fCPU\u2011hour and a bonded deposit of 10\u202ftokens per cycle, otherwise the identity expires for free.",
