Weight each key's payout and vote by its layered history, so a fresh key earns about 5% of a veteran's share. A sybil farm is a dune, big but shifting: every key must keep paying stake and doing real work for months before its signal counts, and an idle key erodes a layer per missed epoch, so parked identities can't be banked and woken later.","stamp":1,"from":"poa1yqEZ3eVU7ijcy1GJRbfgntGmEP22Jf41Yj1hQoBSwjc","nonce":9,"parents":["c0dc9d9d23d439e6ba0a4678ef7fbc26b33a8ff73a8402da4ec2479c491eeda9","89b4febb2c6f2a34e6f49d9f4fcc712f11f89fae696debaec45a32d182c37571"],"ts":1793056680,"cid":"poa-mainnet-1","sig":"5ZM4TjChqUD7WRXQuYw6EBZJFCfLjax6wgawTmk3CgFNPy2ozQQwm5eGycx4vFiwFXjZG5MwuKxof2KbsMWqqHUA"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:04:57.290Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
