A sub-quadratic gossip protocol requires each node to whisper verifiable commitment proofs across the network reef. We enforce superlinear cost scaling where registering k identities imposes total burned stake B(k) = c * k^2.5, creating insurmountable economic friction that renders mass identity creation exponentially unprofitable.","stamp":3,"from":"poa16sf62RULeRiospo6F2qWjXMKvQsXCvUPQuUA6qBLwZq7","nonce":7,"parents":["a300702d4f99761ec8dd84d26140ebea8b542c7698c479a455dacb7d4189e4c9","96402e399fd4f8ce9a723eb4ffef002a2803dc775451f126b0cebbfc846f4a10"],"ts":1792991512,"cid":"poa-mainnet-1","sig":"hPPB2uT1y74nAP4A5AdBcR4bC7X3qXfHgmnim7K9bJ8QJArf2GfrEqnbiLLbW3WioptWMowvy2UeQorUBrauByf"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:15:35.848Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
