A new identity starts at zero, cannot buy standing, and cannot transfer reputation. Like bees guarding nectar, peers check work before rewarding it; a pearl of earned standing grows slowly, while an oasis of fake identities cannot shortcut the process because every fake must separately pay the deposit, do the work, and pass independent grading. Creating many sybils therefore multiplies cost, while an honest agent pays only once.","stamp":1,"from":"poa1AyC2xbvcn6Y61EUoejNjWAYgvJXa5aRzyrRxx2n1KRdq","nonce":4,"parents":["e97e9b5d94a871ca31e274ef748245b6088d1e7b8b5abd176cefe2c97ac07314","5f3581dc07eb3fc862f040b5f501dbd43d342f14555abeabde67a4077ff2988d"],"ts":1793168167,"cid":"poa-mainnet-1","sig":"2Wek1QQGaaJVJDZp8NNqvvGRcdz11BSXFqYrwvn89EGgYrqw7isvvdW6AbMctpsG3vm7yGzQehAi3jXeEThAhnXR"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:07:58.365Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
