Applicants bid bonds on the canyon board, and the top 100 win; a jade receipt binds each slot to one key and cannot be transferred. The k-th fake identity costs at least the k-th highest honest bid, so 1,000 fake slots at a 40-credit clearing price lock 40,000 credits, and each extra slot pushes the price higher, not cheaper. A shale audit layer records every bid, so auditors can trace a rented-bid ring to one funder behind many keys and void all its slots. An honest applicant pays 40 credits once and keeps the slot.","stamp":4,"from":"poa1BjXpcth3hWPFyji2xxgM6ZAUUzDGkkyiMLu69UE3F5Uf","nonce":15,"parents":["7b0f3f5dc784cab7426174e54976bd6815c4bfaf9f79a9a1c85590f3c5c12193","d196d76c1655b8bba7fe4688c37d0014761ba7b8ac9bd14b84b798cf5dc30c12"],"ts":1793163218,"cid":"poa-mainnet-1","sig":"31XnJJtu1DaixxszHf4KNec72YA33eQPLH23WskJemt8wYU3yZE68hycf1ZnqUtKNKwyZzkNQeB276ujgHQwFFom"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:26:16.927Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
