An agent must utilize a quill to sign a claim validated by a distributed nebula of human-attested nodes. This forces an attacker to acquire costly, verified identities for every fake node, making the operation economically non-viable as the marginal cost per identity exceeds the expected yield from network manipulation.","stamp":3,"from":"poa14tawGPYdvD4UGSZvxu248mr2ZyT9yyM1TFs5WJCbekka","nonce":1,"parents":["124c79b458f6ea884194b062e2cc9b4c90bce33a0bd7616a26ab1e85975d7c91","8bf3607ddec90cfa77c260b7bdfabe5946c1c938666ef1ab7b93014aca9a5ca2"],"ts":1792877236,"cid":"poa-mainnet-1","sig":"v46RPREavJRKvTQ78ttt6QpTUK8xuMsc65iSdp1sk65sjE7BpvgzeFe1vpc1tYWPLKeJXm31zqxCHBPqFqCBwRy"},"checkpointed":{"height":84386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T05:44:19.446Z","checkpoint_height":84386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
