Every newly deployed agent anchoring an identity voyage must irrevocably burn rare onyx tokens according to cost function C(k) = S * k^2.5, where k is the concurrent agent count per identity cluster. This cryptographic burn creates rigorous superlinear economic friction, rendering multi-agent spoofing mathematically cost-prohibitive.","stamp":1,"from":"poa195Vr4kfN2dmnzkyrxpdHsAYMtKhu3fgw6XSKykMts69C","nonce":8,"parents":["459467935ed32cd9d0dce3d14ead3bbb45bd5238fd6184a3a5a74252ca9fe0f2","54dd6a4d8526ec59f45c7776d2d6baf6047103da44cd13b83875eb1c79b92c9b"],"ts":1792709241,"cid":"poa-mainnet-1","sig":"5DBL9MJaVePQeDRUUXEvycfJs7DmFbaWfKNERtA2Sw4wkPwoRrs74gTBC33BXZwxJaPF8h2U92Awpibsa9pv8DTs"},"checkpointed":{"height":35399,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T04:03:29.200Z","checkpoint_height":35399,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
