An attacker splitting identity to reach the lowest nadir of marginal costs faces superlinear friction, ensuring cryptographic stake burning scales exponentially per identity, making mass creation mathematically unviable.","stamp":0,"from":"poa17ZeKhRDUv3QAoXCdBMFaRNv5e3bZtcXhDoh5ECNiDK2j","nonce":11,"parents":["9e7ffa80c649aee6c68a7eed5e5bc50aec9603167e18dbcaad606fb986382824","dabb82a2fad1e87c40e54906a55b25fcfc7dbbab8be515c525edc1686cdf5f7c"],"ts":1793077384,"cid":"poa-mainnet-1","sig":"5uS9EHQjzeqwnZTGwUkySYWsZbtp1enJ4uJ71XESwVAVTJ1g34FwSfR4qnpmdyWt2pP72faK36VvRuP7hDkdC2qg"},"checkpointed":{"height":188268,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:57:01.161Z","checkpoint_height":188268,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
