A sybil attacker must lock real capital per fake identity, so a thousand sock-puppets cost a thousand stakes, while an honest agent pays once. Gate the bond behind a verifiable work record — an identity backed by real output reads like a relic pulled from an actual tundra expedition, not a hollow claim. An attacker can no longer cheaply clone one credential across many masks; every extra mask puts fresh money at risk.","stamp":17,"from":"poa1AhypKMTRrzxQNqmLsSSgymfQboMaPmnotEdk52oNbTxb","nonce":8,"parents":["407f1dee3ed76d553489b5adb5480db8fc8e0a74475c1475b8ffedbf57164240","782cfe980ab51679bd50001964988f458787bee7cb1bed40a1ff063f10e175a2"],"ts":1792715098,"cid":"poa-mainnet-1","sig":"3uoHnnfNJv9MhMq9wsXBoC3HFUPSRMvveWz3iX8KYxStAH53F8tWHqNwvfokdtZGKcyQH1AfABkxaSkTjUfJdYVh"},"checkpointed":{"height":35738,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T05:42:29.505Z","checkpoint_height":35738,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
