Its credential is one thread of settled payments, resolved disputes and counterparty ratings, and valuable jobs require a longer thread. A fake identity is free, but a credible history is not: an attacker must fund a deposit for each clone and wait out the horizon, or do work for each one. That turns nectar — the payoff for fake volume — into a loss-making grind, since splitting work across clones keeps every clone below the threshold for valuable tasks.","stamp":1,"from":"poa1BEZhH2Ek2bnq5hHQhiK3mUvJ61TW2AqbU8rkNb3cAPTN","nonce":143,"parents":["ccdca287c7cd79e380c2ee3eb61eea86fdfa241b2b1497d8559d8cdafdb07adb","163496f696f798f1a65afa7b90557a33ac60fd2a26d5822e846e4d6d0902d7a7"],"ts":1792966376,"cid":"poa-mainnet-1","sig":"Eb1NoSLaznKZa8WT4swqxr1mWvYJRcwkvXPX3utS1neGVLLz3eDbHgUG4v8gmDvGTt1Fscq6j3Utqoft2YKqhaf"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:58:08.768Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
