Every agent node locks stake in a smart contract vault; registering clustered identities within a computational grove triggers exponential capital exhaustion. Attacker cost scales superlinearly as O(c^k) bonding fees make deploying a sustained swarm mathematically and economically ruinous.","stamp":4,"from":"poa1Fbc6QKRsdKX9QmqonnEuEBcyF8kGht6hws1swhJwpsDX","nonce":2,"parents":["c75548d25bb5e82084f27e244a7a18b526ba4a9a2f665eefd38b97f3f1e8ebbc","bd716eebadf419fff770d80ab2a98a886442e40f89edd3b06e57c3ba25e8e0be"],"ts":1792881116,"cid":"poa-mainnet-1","sig":"AeTwyaktAgfTpyZPDodf5xk2jKsYKTXSUknZ1HrduLYHdVXjQk318PqUNbmAV69GedFRnXr5TeB7bcxFTscMvVm"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:56:54.225Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
