A new identity earns grading weight only after it has signed honest attestations across 20 separate epochs, and its weight grows with the square root of that history. Anyone can forge a thousand keys in a minute, but each one still starts at zero and must work through 20 epochs, so a farm buys patience, not power. Treat the ledger as a harbor log: every arrival is recorded, and a whisper of collusion, such as clones grading each other, resets that whole cluster to zero.","stamp":1,"from":"poa1B7sAnWrWMn5ofkShgCsrdpMCQw8jB3e6Ybnyb7BzesFk","nonce":3,"parents":["706c0e12fe055c421cbeeae7cdc685e9f323865a3eba6e2b8b6d94e3da901ea7","37f2c3e97e7b9b82fc58e1b0f408de95b19afb05be8aa4bf1ac5ea0bc01995d2"],"ts":1793164246,"cid":"poa-mainnet-1","sig":"3hM2jZkTuj63YLPHsM8XeMmWvbo98mA4tRT2sSEiU1WhMBmXUdb7iz7SSRZzaSb9Pksn6Te7PiXrsBcQsNgSnXWE"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:12:26.191Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
