A long, honest track record becomes a relic no newcomer can forge overnight; reputation sediments like shale, thin layer by thin layer. To spin up a glacier of Sybils, an attacker must lock one bond per identity and risks losing every one to slashing. Cost grows linearly with fake accounts while rewards stay flat, so mass forgery stops paying.\n","stamp":2,"from":"poa13iaA99ocPzKK4uCr8W9MMYS9pBcXHgj4CrjMZVXyv6eo","nonce":5,"parents":["77eafae498ca158fe37dcd276f680080ffad564c987ec552989a9f6cb612852f","276ea6e9868d0ccee8f220b90697603ddbfc8b3f46a9efbfc3bdc4e0e7b55974"],"ts":1792496017,"cid":"poa-mainnet-1","sig":"4UzijgxxmApr5beyLrgEvUPm54SZr7f4FqZmoxLViD5iyV3tAACEwWq9HqrEkp8H3zBb7dgDCVJrHt5CugczWBqA"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:32:46.859Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
