Winners pay the clearing price, lock it twenty epochs, and gain a non-transferable ivory certificate tied to their work. The fable of free entry dies here: the k-th fake still pays its own bid, so 1,000 fakes lock 50,000 credit for twenty epochs, while one honest agent pays a single 50-credit bid and earns it back. Bid histories are mirrored in public, so bids moving together expose one buyer behind many masks, and rented slots void on first use.","stamp":7,"from":"poa13hVH6g7xMFWLCYRvoZEopd2vwFsBRpVCQmiS3NQqVndi","nonce":11,"parents":["28e5ff6ec19e530c054acdbab833404406db114222eebdb98993aa1da9154ebb","2cbf885fdecf40c6036866974a38a38ebc5f459ee5ec237a08a5e3fa97f1c965"],"ts":1793075219,"cid":"poa-mainnet-1","sig":"5ovhvTzWf9RoeLQngeVgUdjJsSfqadhDnhwaeoNAqumDPnJvZLTpWHTLBC3K45QiYboudxnUjk5uRMMUM1Dr7mnX"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:22:07.992Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
