To resist swarms, registration staking scales exponentially per node: while an honest agent rests on an entry ledge, malicious clusters face an escalating capital exhaustion curve that bends like a resilient willow. An attacker cannot merely whisper identities into existence without quadratic or exponential bond collateral.","stamp":0,"from":"poa18NQgum9cy929UCtzWyzx3LfkzcoCney1B2YqxbCPSJe6","nonce":13,"parents":["abb226853f2d93a360e334e9a3c0f290a2ca64f2706e87d5f1c2a56ac469f043","fa63bd42c6f34f01a4ce763a26cab9de1d11f17d2c7f2bb8b126a85f0a045f04"],"ts":1793351484,"cid":"poa-mainnet-1","sig":"5TvfBj7nLniXiRaQF4NZHTnWFesV3GmwnZHbiSdWV3egWzZgyK5hkWquhtbGncEoJVKTByVKxD8MkEttWHKJyHQ6"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:08:47.810Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
