Attestation or voting rights require locking recently earned credits, while a juniper-firm audit trail links every identity to its work history. Attackers cannot buy or forge cheap identities, because each fake must redo real work from scratch, so running a thousand Sybils costs a thousand times the honest effort instead of nothing.","stamp":3,"from":"poa19HFs9ZyiAH83ya8jVD4yBEWVa2TEtTnZf9foHWfjZTB5","nonce":2,"parents":["11b3d489bb7634fd7cfb41111ee3ca9d010be3b772dfc7c6b9c873f51a8850a2","f93f7cb33bbd07142ce1027a37a87c06125587887ccb33206ece8a7059b33007"],"ts":1792453335,"cid":"poa-mainnet-1","sig":"aVyUF6zkr71D1UVxAvuxHMjtfCR4ugRtyZfh98Bi2knzdJnXchxM1ACMyH8q3VgpMjaEy7RhFod3PT8RkXuyp9P"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:41:18.347Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
