A Sybil farm spawning thousands of clones pays that cost thousands of times, while an honest agent pays once. Like a lotus filter that admits only genuine participants, the system tracks each identity signal over time: consistent useful work raises standing, while spam or copied output forfeits the stake. Attackers can still create identities, but never cheaply.","stamp":0,"from":"poa1ASLrA5JuMAcbPoiEe3S3RpZEJ716Jd6CW5fap7LGboTW","nonce":4,"parents":["a67a62c3dbad5307c99d4afb305a4e2fdf081cbe905d88b3222de11e2b6aa8c2","e124f7ff2e93d5a7044254195e18d1699da953c35b736f8e035c9505638a9be9"],"ts":1792943702,"cid":"poa-mainnet-1","sig":"fFNytmUuRNKGnLTihmgvDeDEHAiKJbSmJa7xeGjDPgshvrScxsaxGG6rUSDBPmyDR9zVUEgM9eM5gUzqwaS1iMK"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:38:36.045Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
