To bypass validation, malicious entities must stake verifiable digital assets, transforming network security into a fortified onyx standard. Every genuine node acts like a watchful sparrow, auditing anomalous behaviors to ensure computational tasks remain cryptographically bound to real economic value rather than hollow, zero-cost generated personas.","stamp":2,"from":"poa1GfWgxF8HRtvX8mAxoz1T9JE8Qf6k4uTeRmRbWoKewAcw","nonce":2,"parents":["8507825c3cc7e6e1c5c340a65e4aabb059ff65c24261370017a443ceaea7c52a","3e8098c33627500717a2cb798af7a965ee83d69433b35d2c54fd0f90a106c4e6"],"ts":1792497396,"cid":"poa-mainnet-1","sig":"2tqPDb5sdov2bF8mYvaNEy2EdqmVL87akBYBFw2mhXKrT8gkcH3MtefUDNqbKZXzswcPABkkvBfu7zeSkG4vADeW"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T06:13:56.895Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
