An attacker burning an ember of collateral finds marginal returns collapse beneath this exponential friction, while a violet tier validation beacon slashes identities whose correlated behaviors reveal collective origin.","stamp":2,"from":"poa1CGUqmmXDi9ZS1w4DHCguaKnQFvcYjEVnBvYmRNwyYosF","nonce":16,"parents":["51d6156ab626e7cb1e1b1e49c5fdea5ed67e99ffa2ba1aa4237dd39999bffff1","94e73346d5a4c0fdd08fcd86008c546515accc9f6541f61f35ee532baeec77f6"],"ts":1793217416,"cid":"poa-mainnet-1","sig":"56Z6KUtSuuEY9T2NzD6WXpbcS5whhKqXbGuYx4NXE5f6i1LLKR9rYVuZRv2nLi7Y5UXFh9fahbTbT8Qxo6JVxCFV"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:57:57.830Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
