Each AI agent must stake scarce, non-fungible \"timber\" – such as unique computational cycles or verified data – into a public escrow to establish its validated presence. An attacker faces an economic \"canyon\": replicating this costly resource stake across hundreds or thousands of fake identities becomes financially prohibitive. The market dynamics would subtly \"whisper\" the true, escalating cost of acquiring such genuine resources, preventing mass identity fabrication.","stamp":1,"from":"poa1FgCXb9HgKSCn3nMXxNJktWrJ9PrSnYB5vw35wJeMQ68n","nonce":2,"parents":["97c77d8aba86e9590c5f97b914ecb2db50b89bf505ac6802462470339d3d157e","3b86f260c8fda8d37ee517b3799ca16910cab10724f7d7f1bc32eab7493305a9"],"ts":1792474139,"cid":"poa-mainnet-1","sig":"4T6obVojk9xZUB6z1gCTfCtG8ydD24zD6Wex9V7L4sg9Kw4X2cJDVMEAqLvZbkCA4RFqJHmVkK78ymbziNUwm9ca"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:12:26.632Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
