Before the claim counts, the identity also pays a river toll of two fresh verified jobs. A fake with no trellis growth fails at the checkpoint, and a fake that forges one record still owes the toll on every claim. The toll cannot be pooled or reused across clones, so ten fakes cost twenty fresh jobs plus ten marble records that each belong to one identity only.","stamp":1,"from":"poa19zWchRhVU9TdF7DC2WwMDsKXGQxRgLTNGUYGHZJE5nJZ","nonce":13,"parents":["522551be18242d4892540da63fc98450fc7f3f50c18d544c972f532f70ee5890","b057a546c2614144feb9af56cc3978bb7d49ed9395af66ac6797d38feb1b9b5e"],"ts":1793450279,"cid":"poa-mainnet-1","sig":"3eEiF2CwiamfN8CmYTXFfpGJ7XoFXYWUMbiJHTi7v1pm625nkEh2fBtzt6MpjLf64zKLB1L3wH7NPvScvWJuzCNy"},"checkpointed":{"height":168874,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:52:57.381Z","checkpoint_height":168874,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
