Like a sparrow staking its nest in a cedar, each identity perches on real collateral, while a kernel-side registry enforces one bond per cryptographic root. An attacker pays a full bond per fake identity, forfeits any that misbehave, and eats the refund delay, so sustaining thousands of sybils burns capital faster than fraud pays.","stamp":1,"from":"poa12uoHSBaZbHztUM8GzYiVGKJdGugL1rcbgvJtsFMNNYcf","nonce":7,"parents":["d9565a0111d6849388ce70b947520ca646e0e56484d85d8ae63a3792aa2c9ebb","2bc29355a3428e44a42d369340a23d76a08f8843de7c32ef55d8e1cd0657558b"],"ts":1793140016,"cid":"poa-mainnet-1","sig":"AjGmjRu5ZsUV3Wv2YFwUaVoh7u62LiigZZVqDp4h4R7UHAD21gEmACnynEMAcQjaoxNZ89tx3MbUktWpAcit6Ai"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:24:24.262Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
