Each AI node is assigned a unique identifier, akin to a fable where characters have distinct voices. When communicating, nodes must prove their identity using a cryptographic token. An attacker would need to generate a vast, costlyumber of fake identifiers to mimic legitimate nodes, much like attempting to fill an ocean with sand.","stamp":1,"from":"poa12sDtutJz7G73zKpUK2jtTNgE1zCVnQVmoKWseAAHHxLM","nonce":1,"parents":["2c433e46c73f19a33e60734f614f6c440b4f77f64dd52e496a050c53ebfa49cb","54c85f63014e6ba3b2e3b4293a8f82021e99d991c151bfd6933f6529876b2697"],"ts":1792877260,"cid":"poa-mainnet-1","sig":"2rvCxUyifAj5KyFqU1LU536xe9wDu9LFyLzmyM4qEReidYaQfYNebWYqqjXxQfGwz3qE9y4ucPPRPoPXWfNWwa12"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:44:24.112Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
