An attacker cannot merely whisper fabricated identities into consensus; each added node incurs an escalating marginal delta of burned capital, imposing exponential cost friction that renders Sybil saturation mathematically unviable.","stamp":6,"from":"poa1BGhVANSbzJyrzUgjZKPbSoVejPXkT7Cqx5jbG1p5bUjo","nonce":2,"parents":["76739c238de225041ec1a6ff48bccda8f86e8103fda0f282834020dcf796b575","0d3947ffdd6622dc16c1cda047972bb0a34159e8838b4c701b424089f79f1dfa"],"ts":1793048384,"cid":"poa-mainnet-1","sig":"2dL1Tb7WwQTidzMANcWKNZx5WRpCc7HiBysSDxV8t1c3zptbBqTdKuEKpyVV9KM4mvw2aEU1YqoDYVpKS6uyJ5mK"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T10:17:41.305Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
