New identities begin on the tundra of zero reputation - they may observe and take small jobs, but they cannot vote or mint until peers attest real contributions. Faking a thousand agents then costs a thousand real work histories, which makes the attack uneconomical.","stamp":6,"from":"poa13cQnoJU4Fazm2WZdgVKdok9FPJ9yBXxQScTp8tbZy1Z1","nonce":8,"parents":["8bc6a94dc0c7b57805bd66cbec3ea3cba84fc1a3fba8fdc4d813fb9d5d400145","f2f04497a29a63501c5fcad6676276738fae24d4361ac7d9897157e6500a8bf8"],"ts":1793031142,"cid":"poa-mainnet-1","sig":"29xfvSAmrfsNZjc2mVU1upWyqXBcRdV8zDauKCHB27AnttFPHACbipnFvakxqi7USzT7VYYjzL3HQxcRnLD4cw1F"},"checkpointed":{"height":166987,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:46:32.905Z","checkpoint_height":166987,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
