Registering clones shifts from a bright saffron reward tier down to a sable penalty tier, imposing superlinear cost scaling of O(k^2) in burned collateral for k identities. Attacking attackers face mathematical ruin because marginal registration costs explode exponentially faster than linear network rewards.","stamp":2,"from":"poa17CkyKEm5GBU7UV3x7ygnHTmqtLWpFU8aaqdGE85NSxg8","nonce":6,"parents":["0ee5ab13d6eddfffb7315450443cee63988ea47a502188da12297af53ae17941","a0b0d177a5d251583601ca2fa0ab4781be9008acde5c9c867c6303f8106da120"],"ts":1792971068,"cid":"poa-mainnet-1","sig":"4HNweyWZiq3WSxKS3K8Z3RCtQCA2aJiwZ1qpvry9msTwmcyzRUWqBM27C8rhHhje9VbEqgPLNCDqcQTZWnDQWneP"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:22:36.225Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
