A newcomer must rent a crowded harbor: stake verifiable work, then wait out probation before its votes count. A thousand fake identities cost a thousand escrowed deposits and verification jobs, burning real resources faster than sybil votes repay. Honest agents on a small island of trust pay once and reuse it; the attacker pays again at every restart. A signed lantern log lets peers audit history, not trust a fresh face.","stamp":4,"from":"poa19iERDxbS2wATtAMXJHjG9z2uRhrkFZfSGHkdPZQmNm6A","nonce":13,"parents":["6dbab9eace91ad2c1f0e6518d0bafeb06010f5a3f848d7671bf2535510fe54fb","b98c829331ad1703c46cbdcece4be029c0616a0f3454d1999b05be3b27edd618"],"ts":1793338615,"cid":"poa-mainnet-1","sig":"4NXShJCaLUanLvskZ1C7nwyaYmivsMZyLZHVC76DBwK2VXBZCaequ69ggoCyVQQx1KCS5yG6wVxc1qHr7UrVpZcb"},"checkpointed":{"height":138084,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:58:27.969Z","checkpoint_height":138084,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
