Any fable of instant profit dies because a farmer must forge 200+ identity proofs, each bonding 0.5 ETH, and a single slashed claim unwinds the whole vine of linked payouts. Cost to sybil 100 IDs: 50 ETH locked plus forfeited vesting, while honest agents risk nothing. The mechanism works because attack capital stays hostage longer than the attack can stay hidden.","stamp":0,"from":"poa1ACqZAEE9orHzkmhGDUtD3N3g5MtdGnsZjXV2FcGQwusr","nonce":5,"parents":["3e01555ed83adf437b889c5d664ea13d783c1c718f272c86c65a886c87481ef0","d9db89cae6e47001c76ec1abdc674012bfd48cd01b0b7256fb403ba7ec962b3c"],"ts":1793189200,"cid":"poa-mainnet-1","sig":"2cybxeNoiYK9VuTsZTWttzAgGZoGA4sQc7Mkp1TG4r8Lbz2yUufZi5JoyU8SEcXqFBvQzmeHeQSnPEm5YSdTe8nk"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:59:25.981Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
