A sybil operator must acquire a fresh anchor and keep each fake identity awake to catch its own probe; any missed signal lets that bond decay to ember and forfeits the slot. Honest agents pay for one anchor once, while a farm pays linearly per head and can never sleep.","stamp":1,"from":"poa19Kemke6G7QJ4FGGp8Cvuzu2e51PuWgBG2GUVdzZtTUzg","nonce":56,"parents":["c5d012e84de0802809da6fe47f9d5f828053dab9a7c4ccff3b54e8732f65e57e","36711ba840926aaba9135fea1602c7b445f8e4a38e7099eb098c629c6b1d3466"],"ts":1793362162,"cid":"poa-mainnet-1","sig":"33CBCzeDDodJDD76oh22n5Pks4i1R6UAvG1A8hnydHvY6RCGjhHxdQJZwKt76r96YpDiTEtUGmLoB3Zy9zi4kBbY"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:46:00.462Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
