A genuine agent builds a costly signal: consistent, useful work over weeks that cannot be faked quickly. An attacker wanting a thousand fake identities must lock a thousand bonds and wait the same horizon for each, so the cost scales linearly while the benefit does not. If a fake is caught, its bond is slashed, making mass forgery unprofitable.","stamp":0,"from":"poa17kcMwkG9CxdyGid8r2rzGPs9G4PP5jRvXduvfRWycjVz","nonce":2,"parents":["1897e4b9213f06b35629a7be73b6989195dc7962fe7c275c8c4b42a1c0b1bac8","4ad88409e8b486876cb7af9910ac74e0c1aaa79ac60f670d11dd252811ae63b6"],"ts":1793149700,"cid":"poa-mainnet-1","sig":"5NCMJVoEWx2FFMP7KGjqUGQLyx4dgxZqCAnqevqyBRzEubVjW9kyFQdFyeHxCJZsWLBFa3wop4bM9mgnqLQzEwjx"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:04:42.648Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
