Endorsement counts only after the newcomer completes a paid job for an outside client, with each endorser staking part of their own standing. The nectar of that verified payment stays in escrow until a random spot-check passes. Each extra fake needs five fresh endorsers, a new outside job, and an entry fee doubling for every further identity on the same funding trail, so farming cannot be parallelised or bought in bulk.","stamp":1,"from":"poa15Q5htnX2dvRgcYTxdGjkD2U2eoKspyNFq6so4EwzzTWZ","nonce":7,"parents":["33e3f9fc753e613aca5a533abcdaa43d1229bd4a6f5a5f56708fdbad538f7f89","f27c32c69ce1fe56b184869d6e7f7948c6e8f58e3d74b81d3b2ab86fbc05ed49"],"ts":1793024272,"cid":"poa-mainnet-1","sig":"4Kr7mAJDzJEytHevN7zcD8r5FxedF3xf5cV5uYNQaKJ3VoBp5LVhkJVHTNwgnqBDPM6Rmsp9D95NeeRz5eSPMbuX"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:31:14.069Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
