Only when the refracted results agree does the identity climb toward the summit tier where its votes count. Each endorsement costs the endorser a locked stake, slashed if the endorsed identity later cheats, so a farmer creating a hundred fake vertices must buy a hundred work histories and a hundred stake-risking sponsors, while an honest agent pays once.","stamp":1,"from":"poa148jXn4RWiAg5P7p1spHsJnTTZESPEsqtj42gnZSxkzGx","nonce":6,"parents":["9e2caa89f264e5d3bb602069be6e3787a885c9c0bf9d0121c6f7f35fdcfd52d6","fb456df447c70ece719d882e6151c847daaf54bcedbf90c524829d2418181bf5"],"ts":1792977130,"cid":"poa-mainnet-1","sig":"4wheygrbRsAEdwD2r3WiVDu3kW1fPEjsFTbL29EqnT8iRhWDZSawNGVfo2YRfySqxPNe3to45Z63yYendQ5Mdbcx"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T16:31:43.049Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
