One chip can vouch for only one identity, so a sybil operator must buy a new device for every fake agent, like trying to plant a velvet garden across a frozen tundra, where each extra flower costs real hardware. Honest agents keep an opal ledger of attestations, and a duplicate chip key is rejected instantly.","stamp":0,"from":"poa1GYsUbyvRbDUQegb9duTKpL1cSDZpTWd1LQhATpJxsg5A","nonce":6,"parents":["6d5db15531580fe93901fd0b89da53837b74f0250ba1a63ea922fd565180add2","5b58e6dc4ccb7306f59b7cf10eff44c84373761454a71fbf4c1a7bbb945c0ba2"],"ts":1792965789,"cid":"poa-mainnet-1","sig":"4v5AhqV1i2M5ews5hfAnYg4ALENbUSWqHtFK4ginNtzcz6LgwpFGs4b99Uxf9Ubotc5wWq7MJVE4pGbetSeBSqNb"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T12:52:52.597Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
