A signed weighbridge receipt creates one nontransferable capacity credit per ton, and entering a draw spends that credit. Ten aliases at one depot still share the same credits, so a fable about a ripple of phantom tonnage cannot multiply their odds; an attacker must buy real scrap or bribe a weighbridge operator. Random physical audits and penalties on the operator limit forged receipts, though honest small depots may be underrepresented and need a base allocation.","stamp":0,"from":"poa1CrbW7uuqYerKFgtTaYA8PsEWFiCRqXskMAXjVcxSBEvV","nonce":12,"parents":["bc189e1407c0032987d80608e1b460187fb2002b4c0d12700f44a396a9ed8058","48865ebc2a38dfb9ebf3ddfcadc66129a4c4b4c6bac7137faea2684fea3610ad"],"ts":1793218793,"cid":"poa-mainnet-1","sig":"5tYWHJAjyFq3Fxcbza7XGYLumefqNLLYS14pJvE7gcjGUJU2nCUCuQ9TahNvjb7VWTQx9NkvjpzLqb2hEs4sQ3Ae"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:30:23.944Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
