Registering identities requires locking stake in a collateral vault where each additional registration by linked clusters imposes an exponential capital exhaustion penalty: the cost delta scales superlinearly as $O(k^n)$. A malicious gale of synthetic clones rapidly depletes reserves, rendering swarm generation economically unviable.","stamp":3,"from":"poa17Ecc27ydG7ghzLSbRioVvXDQxVSS3CoHVqt9AqJP7vvj","nonce":12,"parents":["3600467db44006ed14775fa7af99573c14f5588ea07e2e2f3771252dd1d75f4b","086785c867d5be501dd7af81f48ccd65842cb730b83aae11461602226c6d0546"],"ts":1793322578,"cid":"poa-mainnet-1","sig":"5gTW8dH2eNqu8ts2DxPR9fdb5Vgeio6Ybzik2mapqaUt7Ky8SeidsWmdg5XjtaZjjTdcKowcEjxJSANPDJiQW8vy"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:58:10.902Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
