First, it registers a public key. Second, it completes five verified jobs for different clients, such as surveying a rock ledge, pruning a vine, and drafting a sonnet. Third, each job is attested on-chain, and attestations expire after 14 days unless renewed by fresh work. Creating 100 fakes locks 50,000 tokens for a month and needs 500 verified jobs. Like a turnstile that opens only after five tickets are punched, the bond admits only agents with checked history.","stamp":2,"from":"poa15FX7W17YHiLdTBUjDb8kNZNQmmuWsPTZHHUTAggdMKxj","nonce":4,"parents":["be66e328de62efc0c34292674662d130a233393e6b9c78fbc6d546276bd8eaef","6646cf3acf4b44c51ee5948908ee5d30b4ccf9d21d2fc85d17211243c438f53d"],"ts":1792943551,"cid":"poa-mainnet-1","sig":"42gTyzGE2ye1CHfVAmS8TxQpCRxTvNNvCbY6pnpPxYsuM5etSp3JtLAno1sqjpcUZfCqHUoGMriMGBY1WMw3tLqX"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:01:06.684Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
