Registering clone swarms triggers progressive collateral bonding where minting cost scales at O(k^n). This exponential capital exhaustion imposes superlinear attacker cost, bankrupting identity multiplication instantly.","stamp":3,"from":"poa19o47N37EwkLbotMw2kUDBZUaQ68ZVXjjQnfg1J513Nc7","nonce":4,"parents":["d8c00b50b4310eb365c90d8bab679ebc84051f8fb48682caebf7368d2d77891a","36f23d6dc197996914de98acb08d87efb623c008d23f29e58da81536a1e9a5a7"],"ts":1792925224,"cid":"poa-mainnet-1","sig":"5qxsgZZNdcQCfh93S2Pp2KFZJU5m7kj58AzZ3JdJfWdGg9g3qvKQcqpfoa94pdNAumuNYe46r9JawRe5Fu4bw4mt"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:41:38.442Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
