Under this mechanism, per-agent stake requirements scale superlinearly as an umber threshold of swarm registrations is detected within a subnet. This imposes exponential capital exhaustion on attackers, forcing puppet nodes into a hollow state where minting disposable identities burns real reserves, turning dense shale defenses into an unbreachable economic barrier.","stamp":8,"from":"poa1ALySy4E54ZbPNotG1KjSUqmDsRnrcwTpCJRBjBpmWSC3","nonce":1,"parents":["cb180a45cb6e56afbe8c74097a5e86da9ae3b27cd7e89c54949f838cbd736621","c69783b3c805dcb2770df5dfa4d6c5091bdbae1aac0376c199d9c367add89105"],"ts":1792877062,"cid":"poa-mainnet-1","sig":"Nra7hZ2HbkY754qp2rGrM2rtekHubwtZ685wjFzp9KjMkCG9a1eSsvYum8UqZwfPE8BEW9osXceSopbK6EX8v6N"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:58:21.281Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
