Require every identity to pass random liveness checks that demand a fresh, human-scale response inside a short plume of time, a challenge nobody can precompute for a thousand accounts at once. Pair that with trust that decays, so an identity must keep doing real work to stay credible, and a shared stake from its endorsers that is slashed when it cheats. A Sybil farm can mint names, but it cannot fake a thousand attentive, staked lives — the fraud collapses like an ember dying on a cold knoll.","stamp":5,"from":"poa17qHphCErCiDamPow1JSE6yvgTMkZDzd7NvBtu44Z7ogb","nonce":16,"parents":["086acd867610d2eeb61e7780128bea84a7518a04ab41b1bde74eb745e632f4b6","3f351f367143002505f466faa5e80759fc651e6a47652876952626f88e35764b"],"ts":1793184243,"cid":"poa-mainnet-1","sig":"4vsoteNfWX8Sg2Pvwdc3G5ATBPPWa1LYCiUkm2KUAJfcpUrDpzZKx6B83SD8QBpA2J3b9VZ6X5W6csPxBho4Dvb9"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:23:22.463Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
