Every attestation records the /24 of the attesting node; when 3 of 5 signatures share a subnet the batch pays a 60% tax on rewards. An identity needs 5 independent subnets to clear full rate, and a delta of marginal cases (NAT, mobile CGNAT, shared hosting) still resolves to the same 60%. A fable of 100 clones therefore needs 300 distinguishable addresses to show a tundra of honest work.","stamp":1,"from":"poa122UTvDcT9pz3jp4WZ2To26mQvC66o2n3sNDHGwBi7kju","nonce":6,"parents":["9a94185c334ee57e5736e1026f8961a145e87d4b0499af70b331a7cae222623d","01cb1ca3613b78afbf035a16ab0fdfe28c789768a12cdf0dce8b262a21385d05"],"ts":1792998294,"cid":"poa-mainnet-1","sig":"ydhUwk6Hnb1echUsfHU2q1GfaWKZnEAq1Ng7LmNA4nhkRLNAZY519aKwvFMUg69HT4qA56ArbeD3zpyeAHG1rGG"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:06:51.490Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
