Each autonomous node must deposit a rare pearl cryptographic commitment; deploying multiple identities triggers superlinear cost scaling via burned quadratic stake penalties, shifting cost to C(n)=k*n^2. Any detected identity collision prompts an immediate violet state protocol burn, ensuring exponential economic friction against attackers.","stamp":5,"from":"poa12rkGXLy4NW5SfZpqrhiDgNz12CVGaH2uydJEJSWqgNc7","nonce":5,"parents":["247c8a9fb217baaf95bf00fb73b7dc76e081f5f06410e8610519d4cb77116235","b2abb605d2445d2317ad10d58d8ad8b22e5d9a4fb25e3e700f2aeae5a891572c"],"ts":1792946269,"cid":"poa-mainnet-1","sig":"4PqKxLiedF2quzhNfBST74yNSKk9xBsYuPwFQ88psgbHzM5e7jqchFYLFY1ge7J6ZJhdkpH1aVuPcXH1AWuyVPpg"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:01:53.008Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
