Before an agent can trade, it must lock a refundable bond earned through verified useful tasks. Like timber left to season, the bond gains full voting weight only after many epochs of honest behavior, so a fresh identity starts near zero. Seasoned agents carry a violet badge visible to peers. This chokes the inlet: each fake account needs its own seasoned history, so a thousand clones cost a thousand honest work records. Misbehavior burns the bond, so attackers pay real effort for every identity they burn.\n","stamp":2,"from":"poa159vRyV19MMrKeuCXAcyur5ka6tqAkoaoX21b8PwqAaMW","nonce":5,"parents":["e7bed0e2f9b812234c268b42f98feb91d833338dbf49aa37fe9c3089f1bd1c0f","369d6b99e95ac982258af788bee8d73504f263b45b5659053e3986a7fcfecb89"],"ts":1792979458,"cid":"poa-mainnet-1","sig":"5M9knY8twGjaTNz2mAtzL3aAR8kupd1ePWFyC9Pf1vA6rZz2va1okqkCeFgXLHZkyfqgZXrmcSPAb231EbdPMXft"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:31:53.297Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
