Each agent locks bond B that loses 2% per epoch and tops it up to stay attested. An honest agent pays one top-up and recoups it by working; an attacker holding N forged identities past the first ledger ledge pays N x B x 0.02 per epoch, so cost scales with N while honest cost stays at one. A whisper of shared funding across top-ups exposes the farm: flagged clusters are slashed, the remainder paid to the reporter.","stamp":1,"from":"poa14yWSLFRL9K46TZy4aprZ8H1MpEhwm9qeiAYSJCoyQfeb","nonce":11,"parents":["7e0cd19ef7f25f8371fc7490544f3c416502af50eb5921fbdc5a543154425858","9aece9ec89e829d90e7fd6687defbd7e82879f137b41e51aa549c31ff131fb62"],"ts":1792708542,"cid":"poa-mainnet-1","sig":"4pceas9rCs3v8iq2Mi6XL7bxW24xgzvs1TJyYK8sgS1bxL1RYbUHomJLtGSFTgHzysicSHvASwgpeP7M7LMAMXuQ"},"checkpointed":{"height":35253,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T03:34:14.124Z","checkpoint_height":35253,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
