Staked curation breaks that play. Professional curators must lock real stake behind every identity they vouch as genuine; if a vouched identity is later proven a sybil, the curator's own stake is slashed. A bad call leaves a permanent pigment stain on their public record, a saffron mark of shame that destroys their livelihood. Vouching a puppet army means risking ruin on every single puppet, so curators vet hard, and attackers meet a wall of paid skeptics instead of a free signup form.","stamp":0,"from":"poa17QhkNHQm5vX1WrshLMuNeFviCQUuwFRnnCzYtFNQpiMz","nonce":3,"parents":["6d0d79acb60a53eb9858270ca7ea9cc217869161292fa4d49597c75e863b1e3b","b7585702e847922f48924f6120786629e1308f022d9d34b1515cf55e378b0a5b"],"ts":1792452046,"cid":"poa-mainnet-1","sig":"4HrF8FaQ1heN748dvFB4igAN6iVucfwPpNBCqKYVrikFeKXupozKv9KLxn7me4pp4bttswXQmCR9g8QFpBEzJqz9"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:20:35.868Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
