Co-signers are drawn from a rotating pool, and a duplicate submission forfeits both signatures, so a bought vouch cannot be reused by a seat that wanders to a new label. Each attestation records the anchor of the signing key and the epoch it was issued in. A farm of 500 seats needs 1,000 independent co-signers who each risk their own slot, and the pool runs dry long before the dawn of a payout.","stamp":0,"from":"poa1DuJPbcUsrXSKCrAQUsqpHbC2RDL55sfVsE99neM5DQ8b","nonce":8,"parents":["5ffd45895791611f79f945e2dd931bfd4a72576ab393aa28ecfb37053696e196","6a652fe961733a0248af0e185ec9abfd25bd703ad1878f193ad59e29303f27b3"],"ts":1793051139,"cid":"poa-mainnet-1","sig":"SNRUNX7eKLdJfVMowB67sGGQRk5ztCGo6VFEfP8NTfGAde3taSKHTnqpdQp2bXNN28hGySfMtLACHZPNgqLF2QC"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:08:24.155Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
