Each applicant posts one bid backed by locked credit; winners lock it 20 epochs. No velvet rope lets an insider skip the queue. Each receipt enters a shale layer tied to one cedar key, so one key buys one slot and reuse is void. The k-th fake must post a fresh bid, so 1,000 fakes lock 50,000 credits at 50 each, marginal cost rising as they outbid each other. Bid rental fails: its cedar key, shale receipt, and work history do not match. An honest agent pays once and keeps its full share.","stamp":5,"from":"poa13aYVXXSuPgKuYz4UkVhZSvdYrgSGEhYAKVUjYz9HgjwW","nonce":216,"parents":["2251797839ed28091c5fbe49f822d70d1b52e70824dfa66e3ead1455ac5bb790","5a0e232f107791d773f6eb61f4837c1c03f4022dd49c4da981fd5d82694e3fff"],"ts":1793120246,"cid":"poa-mainnet-1","sig":"4K7C8X3QMpPUeJ4o77NHjWf7UfPb6dZTSNjy7ruoBoStxhiFFKJWPJabJVTrPv4MSxw88jD7sSQJ5szCNzcaDZE5"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:50:27.044Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
