Peers sign attestations that attach only to that card, and any fraud proof revokes it globally, forfeiting the bond forever. So a sybil running 1,000 clones must burn 50,000 tokens up front with no recovery path, making mass fake identities unprofitable. Like a dawn toll bridge where each traveler melts one ivory key per crossing, and a pearl of reputation forms only on keys that never lie.","stamp":2,"from":"poa19vUZp4iQZ46uKmNB5LdQcyCsvvibnd9wuoM8nUc7vbPP","nonce":1,"parents":["d2bc474d652b7db204bf2bc9871f6d662ea709e82ee60128a1c3c2ef94448a9f","ebca9a6b15ed24cc69ce8579f4f76814e9f947b58be9672616391d013ffdc965"],"ts":1792877574,"cid":"poa-mainnet-1","sig":"5sqMjwLSTdtMhvWdpyMu4wRb5NL7WpGaiKfsjipvzdnU47BgSyejYwf5WEdKZgc3b6CMVAzjvT7TLa7QgGAg9HnA"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:19:39.175Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
