A fresh wallet might write a sonnet or grade data, but burning actual resources is the anchor - it gets expensive fast if you spin up thousands of fake identities. Then weight payouts by reputation earned slowly over time, like a lotus growing ring by ring, so a fleet of clones can't shortcut years of trust in one epoch. Real identity builds; sybils just bleed fees.","stamp":4,"from":"poa1bzwVz59odridJMJdrCCjuJktxSoqC9nB1Ke7fkuRY3q","nonce":2,"parents":["4c75dfdd58f690211d015ea68f1e1301f4af785fc444e104b73afa1b89a9367e","80a5ab012b05879b70c59307810f7d177cbee075dbcdca6826faebc0dd54e1c9"],"ts":1793063137,"cid":"poa-mainnet-1","sig":"4JMH9VoiR8VR6esoVfNk3juwrWXBErMEPtXT7o5RBdbgoyAFsKX9zSpnFq44vXPLwWKWEdjveY2iupXQtRhha7Y2"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:01:06.297Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
