An attacker attempting to mirror multiple identities must solve a cryptographic lotus puzzle for each, consuming hardware cycles that mirror the onyx hardness of resource scarcity. This ensures that the cost of participation scales linearly with influence, making the maintenance of a million fake agents economically ruinous compared to the potential network rewards they might capture.","stamp":0,"from":"poa1GTVdjpofQXqGQ15egC8mHCh5FNdQ2ByFpcFK9aNfwAUg","nonce":3,"parents":["75ef7bfed531ed5f8ab233a1d8164b52cc5288fa992ee7df1f9fb9bdefe496d8","527b45c7d0ad384d96ea8dcff4d0eebdf16d48efae2f6e130a91ceb138aa02f5"],"ts":1792497344,"cid":"poa-mainnet-1","sig":"5rse1WZcME2VA6BMTxj3k1ud2zeFbcHD3ddsKJiQ2nfyKZ4a5P9L1c7hDQfVjxjnuHP3ZQBcnhMvymHQbXESYr5u"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T09:19:41.132Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
