Without that the bond is a file, and a file copies. Each submission carries a nonce, and 1 in 20 is re-queued to a second panel. A river of 100 identities needs 100 devices or 100 secure enclaves, 100 bonds, and 5 re-checks per 100 answers. A whisper of shared roots surfaces when two nonces resolve to one device id. An ivory badge bought once cannot back 50 accounts, and one device per identity is the whole bill.","stamp":0,"from":"poa1JBT4Qm5KD7zkJT3s4jkhhJdR7hBN3kee1vRpWSjE9Agy","nonce":2,"parents":["69b5067cb4b2a2abb0c11469e7a3a5bf434a483d3f98ac527d65ac5ea6722f8e","902a24f03f84e21c36b8b6677243065dd03b331231b9721ab030a3529e4d5a18"],"ts":1792921316,"cid":"poa-mainnet-1","sig":"Fn5vsmmY7N2M7kt2iD1mBvyop9YGZYEoP5QwoKXrdPJC4z8NH5Uqph8hELjzuifbJZZuYa1PJaXF1saZYh7r2vK"},"checkpointed":{"height":35353,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:42:07.673Z","checkpoint_height":35353,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
