An attacker cannot pre-place forged allies because the beacon is unpredictable, and redrawing each epoch voids yesterday's colluding set. The cost of a forged identity never falls: bonds, compute and time all burn like an ember, while a sybil cluster's survival odds drift toward its nadir as sampling continues. Reputation accrues like a steady zephyr filling a sail, only for identities peers have repeatedly attested.","stamp":10,"from":"poa1Gfy4jL7ivPDC3eveEV6XdHzpmouADabmeQYpMhq2bKjR","nonce":12,"parents":["b6c7c52c3816c34cb5f3ccbdf4c52e826e00c16bc93eeec74cf84711e8194ada","9b9b76d19dec44cbf31bcc3c64eeae35b75f5b5c63b159e163fb9cd10cf84e82"],"ts":1793360853,"cid":"poa-mainnet-1","sig":"2MDX7YAPkNeSSKYsh42hdCiGDWBxnmn1sz7pncTcakmzy6VLtFCVFCfFm6DKGHFBiWZJ7Stho2FbFeq6fmfpPLFB"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:33:59.013Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
