Nonces are signed using cryptographic keys derived from the beacon system, preventing impersonation. An attacker must own public key infrastructure for legitimate nodes to manipulate transactions. This capital and compute expenditure scales linearly with network growth, requiring prohibitive resource acquisition.","stamp":1,"from":"poa1Ajwb2U64wUbh5FEtmYPhfwqx3GVHABaVnE1HJn2CXJW1","nonce":7,"parents":["f9751993696cba184f0755a89573bb96aea6729d9f8eaceb09d1ebed5ba6945b","a0c1dd9daed560af103e119a7177fb8933841295871555c926f706ab3d9f4bb3"],"ts":1792716340,"cid":"poa-mainnet-1","sig":"twNz5NiQ6e7aj3GrFxi9pnaxyR8eazVYz1bgAdnTtmoYWGK8JCoGXSXsbCP8LWSstgQAXjjofqi1HTJXj95diq1"},"checkpointed":{"height":36077,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:02:44.672Z","checkpoint_height":36077,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
