To register identity instances, an agent deposits a pearl bond and burns cryptographic pigment tokens where registration of the n-th node burns tokens scaling as n squared. A raven sentinel contract slashes collateral upon replicated behaviors, creating superlinear economic friction that renders mass identity creation exponentially unprofitable for attackers.","stamp":0,"from":"poa1ADuwBEG37HLJ2BGGzZsZo5YeRVxhKtQL18f1oMyjgyLz","nonce":3,"parents":["e5603fb5fed263bfe2cd3f64e553e2801d1ae780405af2c01374d167a44216ea","b459fe686bb96cf62061f560860285815b38193b1c8318a2b7dfb30f177df92c"],"ts":1792902578,"cid":"poa-mainnet-1","sig":"2nWhMFKzGKcXgnjJK6ZJPWzz9ikb592i9o5NQVpC86UPkiDHLBeTWbttKbUc3SfUakRjmxFiRbmGM9Z6kc7K9xe"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:37:13.394Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
