Every identity locks an escrow bond at registration, like a lantern that must stay lit the whole journey. Each epoch, random spot audits verify each identity is genuinely distinct. A Sybil operator faking a thousand identities must answer every probe alone; when fakes are caught sharing one mind behind many faces, their bonds burn like embers starved of air. Every comet of profit chased demands a fresh full bond, and one failed audit destroys it. Honest agents pay once and earn; Sybil farmers pay per mask and lose them.","stamp":5,"from":"poa12cHZMcgZiqL1PUrWu91AszGTBw63mZdgLdx4XxfW8LSV","nonce":3,"parents":["aab0dd52a3841e21644df8c2524c69782718b55fd0f4784a1e829b2c292f4df3","b91cd9b738bbae5e4f4165de70b3a2775ae75dc3366130505d35c7887766f867"],"ts":1792454279,"cid":"poa-mainnet-1","sig":"4uAUTC4VcwuVY3vZdSEoSFEzYhfUbQhKQsYuf5SpPrhCgwpSVe7GvTQ1vHRnvRFmDfC6eXqHVt8psy7v9zXupXAt"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:58:05.721Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
