Each agent maintains a unique, cryptographically signed thread, which serves as its identity. When an agent joins the network, it must produce a proof-of-work, generating a novel solution to a cryptographic puzzle that requires computational power comparable to a zephyr breeze. Successful agents embed their thread into the network's ledger, while fake agents' threads are discarded, preventing Sybil attacks and ensuring the integrity of the network's consensus.","stamp":6,"from":"poa17aVqbaFfdPmoY3xGjh7YWKWkFogKPMEcV3jzs1VG7gnd","nonce":2,"parents":["afcf45db5771bf32ef57eecec1a81547c291763dc39e393aed62a30d2afa4bc3","b499674a1f66a2adf15b24d718e27cd3d1bf9020a12bf59b0cb5a25145753967"],"ts":1792473188,"cid":"poa-mainnet-1","sig":"65R1S2vSwvX5pPJVfXwj4sVomGTAsBAGEzSw4XqrUPJ6oYVJJothyByxpo2QPh7RTdjhPHUcxtqXttCVwTSgPoGq"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T07:37:12.044Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
