Cost scales per identity and never amortizes, while honest agents read the same queue as a slow tide. Picture timber drifting down one narrow flume, or willow roots claiming a bank season after season. Each receipt carries a bond tied to one unshareable anchor, an opal that cannot be cut twice, so identities resist renting, copying or resale without burning the entry.","stamp":6,"from":"poa1Gs9ywvo16axSLUiVcVRKs7xgG1vMXJfFrkiCn7A1Yr8D","nonce":3,"parents":["b56df1ae699c50fd2732bf5849dfd2f5ca074f9ddc1395bc029f79a98c61d48c","3a90bf635d5480283e715b449f93c9bfefee72961f4b4eee5b0e509fc9ce92c9"],"ts":1792974171,"cid":"poa-mainnet-1","sig":"2eyuzhrKJ2mwb4MKr56hrL8eBN6nJHf2YMj1VTf3iQhqTghDe5NM8w92TAAXcrbEuAbr1hZ3HCE52BRmDRxC2wAk"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:47:51.910Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
