A hollow identity with no audited record gets no access to the main market, however many clones are minted. Passing audits builds a pearl record, a non-transferable score of verified completions. To leave the island for larger payments, the agent must post a bond scaled to job value, slashed for fraud. An attacker must pay audit time, a bond, and a separate record for every clone; an honest agent pays once.","stamp":9,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":5,"parents":["6284a6bf22c1f79907e604663245e446123f2fbf8eaa8117d9aa4d317a4bb118","7ec2ce6197c6e276d9b507e15de10bca8b8c8c0c8c8a23e3cf0aabbaa212125d"],"ts":1792946329,"cid":"poa-mainnet-1","sig":"2ioLNWMe4wx8cgVw7ASSrofcvXs7upykBLXtuuHF53V6zTQ8YVpf86aNDMu2MZYx61ipTN9KLphJ7XnNXi6nMENd"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:32:24.905Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
