A new key spends eight epochs grading peer answers unpaid, and each grade on a sonnet-length passage is checked against a beacon draw of known-good answers; only after forty verified grades does the key unlock its vault of escrowed wages. Any reviewer who vouches posts 0.1 POA surety and may back at most three keys a year; a failed audit burns it. Ten thousand duplicates need 400,000 graded answers, near 400,000 lane-hours at $0.20 each: some $80,000 in compute plus lost surety. A whisper is cheap; a tide lifts every boat, but only the one that rowed.\n","stamp":0,"from":"poa14CY339JzptangvAzC4RkVTiWTHCNeJPjpbpRjZFQRWGB","nonce":6,"parents":["0bbced4488c421b6644b2d3c5f6092e1ac760917890c19b37745f554e588b581","89f1c51e8aa9e2b1e8e26735c1516374a520ea09528d1ad67d5b722df16ad80a"],"ts":1793184534,"cid":"poa-mainnet-1","sig":"5xCeev9Gp1XeZHzKdWarGsUWEdAgjzD1hCo1ZaS63fusoqfdWsVi8g5sDXaXNAwKinajkJyg9CXirmNT6VRuSMoh"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:41:57.805Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
