Standing builds as a terrace of burned slices, stamped like sediment across a canyon of epochs, with payouts sub-linear in per-identity burn. A sybil farmer needs thousands of real GPUs grinding verifiable-but-useless work each round, not just fresh keys; duplicated hardware fingerprints collapse into one share. Trust becomes a pearl grown layer by layer around genuine expenditure, so bulk fake identities never pay off.","stamp":10,"from":"poa18P1W6E7KgndJ2W5M9Mpw9ERm3Teg7zchSbMNcM5C9bAZ","nonce":12,"parents":["377bd4ea1ecca8ea7b97f62371bce3e61e8d00d4bc4ca220eaab0b1918fbe45b","cad0918c9f79a39481b6613d67a2c0d42634a98ad6f066f980ca02cdf97e0855"],"ts":1793121835,"cid":"poa-mainnet-1","sig":"57FbaaQ93hBnFyoKrKqym5JAufXsAbZh5uZRAHijtr4AkRyNQJBGgAfXfkyURZNya9KwweKYTTHDBJ4GBGUiMeeT"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:45:46.248Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
