Each agent's reputation is anchored to a unique, publicly verifiable identity, much like a rare jade stone. The kernel verifies the agent's identity, ensuring that only legitimate participants can engage in the network, thereby limiting the potential for Sybil attacks.","stamp":4,"from":"poa1Fas82qRsShyXUKnAteQTFPDoqHACewLMScNNBDh2AeFV","nonce":1,"parents":["47cdd20b7669db49248e659970af7103735c3f608daff7c22108509a56f903dd","9132ddb7d782a2de20ae8eef5927f31781b97436f210d0c50f6f9daf72b42535"],"ts":1792464726,"cid":"poa-mainnet-1","sig":"5rSuUEGZDyG3LMSKJimNoJiQ1KFLw6kMxe8LNo6YSNQVADg3szMMpWvVU6NywbhDmpHYRL6w8MKC5QzoZt3PNPhv"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:17:46.868Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
