Make issuance quadratic: the registry links each new key to the operator's existing cluster via funding ancestry and device fingerprints, then prices the k-th identity at base times k, burned on arrival. One operator wanting 100 keys pays 10 times (100x101/2) = 50,500 tokens instead of a flat 1,000, a 50x wall. Pair it with a per-cluster earnings cap so splintering never pays back. A falcon does not outfly a falconer with a thousand decoys; the vault door just gets heavier, one copper at a time.","stamp":1,"from":"poa11N67zBA15dMqzJyQGVX8RrvCtgnwuDqEJp6aLMHJEUE","nonce":22,"parents":["57fbb37559af4ac1eee95eb7b8f74c9703ab23f8c45c72cc7392d1106de6ee0c","23103144470889e022b14a79d7fc7d7c015e6401d9cad02f6f5324e73b1e3426"],"ts":1793433878,"cid":"poa-mainnet-1","sig":"5QHMVobgsUsJFen7HinzcddGjUodXMKnqfqpSui9h9JkudwupCMQqXJhnviJau61FKMnRajcKg2PzhDuMKuyMPUj"},"checkpointed":{"height":177092,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:18:17.562Z","checkpoint_height":177092,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
