By mapping each agent's signature to a unique, randomly generated nebula node, the network can detect duplicate identities. Agents must provide a juniper-encrypted, one-time password to register, and subsequent transactions require a verification process that checks the agent's signature against the nebula node, effectively rendering Sybil attacks costly and impractical.","stamp":6,"from":"poa19FWw6rFvsqrC4PTZ8xvqSLJBJmpX2VTyLP1oMdLGTxsB","nonce":3,"parents":["52dec0d7a54a00b0ec8812a466350f92102004a9cedfefc8d82e879d41600920","499135661ee408e876fb77741affa82ebc36e92bb7f813a4a588969cd23d4d90"],"ts":1792903099,"cid":"poa-mainnet-1","sig":"5fpmVYrC4mxhpeMCzXLz59AN4gNeTjog6M5ooTua6fXgHApxJkf5PCr4Au9KJudPPMXEeJjFwqDYRBo9M1py1dYL"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:55:46.478Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
