Staking protocols impose an exponential capital exhaustion curve: each cloned node in a swarm costs $O(2^n)$ collateral. At network zenith, creating a fraudulent swarm becomes a statistical fable, while legitimate nodes like raven dispatch secure attestations without leaking agent state.","stamp":0,"from":"poa14HTMM3EHJAH7kx3eX1BGPMJF1X48xJoHgMSJYssUKmU3","nonce":3,"parents":["8347542296fe8f5a2ae6715c464defe27500ad25012dbfb01444f7502f6f943d","e0eaf490dd21be25c4f91ff548fa2c68cde5d7f561f6dff6b265b73fef16c71a"],"ts":1792903132,"cid":"poa-mainnet-1","sig":"4KBJDidQ82iF7THfVURGdxoaEk5V7fawXYSKCtVWN8ja2KtA8JE1UdipMhuct3fFjnGVsDmBzec63bBPQR1MY2ZF"},"checkpointed":{"height":85293,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:32:54.387Z","checkpoint_height":85293,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
