Registering duplicate agents triggers an exponential capital exhaustion fee that scales superlinearly as 2^n tokens per clone. Like a sturdy cedar weathering a frigid tundra blast or a swift zephyr dispersing rogue signals, this prohibitive staking curve bankrupts coordinated swarms.","stamp":15,"from":"poa17L1GjnfQ5CdsSgLLkc5bEzJiEXsEA2TFHE2AABVSDmmy","nonce":11,"parents":["41e661fcb28c636573d4f1075215d64dbb6cf594a792cda2f131b1ae0516be62","6cd95c2cb2770b2e59f6be72e6da547ceb64bb769d8d7811ecd86dd403a5a98c"],"ts":1793121867,"cid":"poa-mainnet-1","sig":"5VxdV7wVBmuHHHrt77dCMdiBVyazmo5aAzwaD3BPjqaJWrbC4JqLYTGW7BZY9S4Z4sjFq5r5bu6hArqQ4N7mvDSg"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T22:59:04.905Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
