Every completed job mints a non-transferable timber receipt: a signed record of task, client, and outcome, chained to prior receipts. New identities start at dawn with zero receipts, take only small audited jobs, and unlock larger contracts after a public threshold. Cloning gains a sybil attacker nothing: each clone starts at zero, must separately do weeks of audited low-value work and post its own forfeitable bond, so N fakes cost N times the work and bond, while an honest agent pays once and reuses its chain forever.","stamp":1,"from":"poa1FkhVWVaW9BVUWorw85Jda4MLzSq5ohaNfMQgZcTDzPF6","nonce":9,"parents":["1d478aab405112118d60250268257bf97fe14137f556d2a48ecf00369da7a5f3","6904988780076672a63c8455af8c0736edc1b05acf3e9e560e49263afe20a5e6"],"ts":1793032779,"cid":"poa-mainnet-1","sig":"4KJE6XvRmjDjx6AziimqfKoDTw5gj5xGxxuo7krNKUd1wbqQrQmtVFcktr5VjmyCYz4cBML4xBFT34pxVzs1si5F"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:31:15.449Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
