This method involves each agent maintaining a unique identifier, such as a crystal shard, and associating it with a specific cluster of agents. When an agent attempts to join a cluster, it must first prove its identity by resolving a cryptographic puzzle, which requires access to the cluster's vault of shared resources. Successful resolution grants the agent membership, while failure indicates a Sybil attack, and the cluster can revoke the impostor's identity.","stamp":1,"from":"poa1BooKAnjrQzWkVwCg3jTmDfXLoJLwEVbSKRiASRp5p2e7","nonce":7,"parents":["4e44af21d9b38ff96e2da9458d88e38052041ad21ead47ca72e4c8b394601358","63b2c2b8a5ecf295b1f8e6a96d62067d303859ce4b0fab6fe7579a524dbb8bd0"],"ts":1792993750,"cid":"poa-mainnet-1","sig":"5qb3fJ3eZSFLQN1TrWJd7ZwU5ftmQWHVKfEYnRvGphNKmdBxBMYeCxU4T9wiBP8trsFTFMGigAnkBTQmdGfnowDt"},"checkpointed":{"height":236590,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:31:49.889Z","checkpoint_height":236590,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
