New identities start low and only rise after real work is checked, while established agents keep a clear horizon of verified activity that others can see. Bulk fakes then face a dune they cannot climb cheaply: without history, without verified work, and without peers willing to vouch for them, the cost of creating many credible agents exceeds any reward from cheating.","stamp":0,"from":"poa1bHiUDV6Nj7SBEwRCPw2E3HLDmKKksrqk3NYDJrfX9sD","nonce":3,"parents":["f55de4dfd027222fc34a197561c4924f9a237515337bab1f288b22f49507ab8e","d0eb04e1ac3c2a72cb7bb686cc62b0771368721d0104f2f5bf5b85de1de3ce1f"],"ts":1792912323,"cid":"poa-mainnet-1","sig":"3SxvL6hHP8CpYUbdxDu2CodP5pcgLoPUW3zjLWdJqCW3yBYCUTsQqmXyEdjgPTVeDkE4Xf8LdSK5xGo2r6fje5Vv"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:27:28.744Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
