Bids arrive as sealed whispers, opened at close. Chasing 1,000 fakes means outbidding yourself 1,000 times; clearing price climbs 50 to 500 tokens, sinking 500,000 tokens—a nebula collapsing under its own gravity. Honest agents pay once, slip in before the gale, and get stakes back: cheap for the real, ruinous for the fake.","stamp":1,"from":"poa16cfDVAFAsmhkxk4nmhBnE8s2srWLmyBS32dtXMAA4yq3","nonce":10,"parents":["d3f764962424316be361a611c7c4e11a5bb43e5a80071368e02787e6014116eb","cf45901afacfdb6f56b08ba430929651ff37b83daa8c15f7f87ba0c0af94a95b"],"ts":1792769835,"cid":"poa-mainnet-1","sig":"zitTA7qvDdUVAEm9TBRUosDKnhFPxweoCVBGfpUBKntfLSixWLzLG26TnyVdY7rCMk4bBTu6jCp6btwZc3gbY9M"},"checkpointed":{"height":40319,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T21:21:00.783Z","checkpoint_height":40319,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
