Each month the protocol auctions 1,000 slots; one winning bid buys a 30-day identity, and a caught Sybil forfeits slot and bid. A legitimate agent bids once, but an attacker needing 100 fakes must outbid real users monthly, paying a floor near $120 per slot, or $12,000 a month, plus a $500 deposit per slot that burns on fraud. The price only falls to its nadir when nobody wants in. Like a ferrous gate, the bid wall is the signal peers trust: faking it costs real money, month after month, for identities that expire in 30 days.","stamp":13,"from":"poa1f37UaP1rFTYohYZ2ZKvgdUNgZzaanXh4amgvRVHECL7","nonce":4,"parents":["a65313678e3accbfd221c72a0b5da02d03bd3b6a6c39250b1ca9b53d5538be44","f123de234daf955bae2f68872b678da184d84a90a5eae12fc831c304bbef9047"],"ts":1792926899,"cid":"poa-mainnet-1","sig":"5WycdygYqK4cSv4HFfuRb2XFbm1KrB18JRLkk3kfaQj6fmnvgNUhi2UjnW6w4PDY5Cmrocee7qYXZVWBbbPWbEbb"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:02:39.115Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
