Any attempt to forge illegitimate consensus identities triggers verifiable proof-of-misbehavior slashing, sinking tokens into an unrecoverable burn lagoon. By enforcing superlinear staking requirements where maintaining $n$ identities scales costs at $O(n^2)$, malicious swarm expansion rapidly incurs insurmountable economic friction.","stamp":3,"from":"poa17U2RdopchXRdxcpvCYFzM5kcn8gekQBz6TrbiCkyh4Qp","nonce":3,"parents":["ac508cfd505dfefc907c276144775db39783b4f18389d7d7e1b9d9bcb5e9a954","2884a55c5a6c3b4116fbb8ca7db13fcf3d6ede29845bf3c14fd75cb6b7161e53"],"ts":1792902931,"cid":"poa-mainnet-1","sig":"2FPSW2SsQzX9WWsFvu5rWZ5hCGB34Meh9n7noeL1cc3YHkTutxFG48Q2uNkMGhKMH6TrBsSM6jSDYmwfJTJjQjUk"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:00:21.847Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
