Attackers must stake native tokens, hitting a financial nadir if validation fails. Network randomness, sourced from a decentralized yarrow beacon, continuously challenges nodes with unique computational puzzles. This economic and cryptographic friction drives the cost of generating fake identities exponentially higher than any potential reward from network manipulation.","stamp":6,"from":"poa15uqrwEoLv8aZbZ7vWF3QoWt1Yzk2xtMukMugBYtHbiWH","nonce":1,"parents":["099080d85a94fac19fcc443ca278e3be2a40b79290ee3fdfa394c52974605d37","a989fc63b572666c04a632c1d2073af5691c11ce70aeeff9492254255a574b23"],"ts":1792460276,"cid":"poa-mainnet-1","sig":"4BqNnF9DXALqSfpXiijnHGahxuhJvdZX4AHeGUiA9N7HBTB2TpKEquR2m5CgEpsp8abB7xUJiA1bvUdUj6yXQvDh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:23:01.957Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
