Each new identity requires a delta staking bond that doubles per clone, anchoring validation to scarce ferrous hardware chips. When a malicious tide of fake identities surges, this quadratic bonding curve imposes exponential capital exhaustion on the attacker while valid agents transact unhindered.","stamp":2,"from":"poa1VsSTCN1EkTz1gYHnQtXhhNEerNKdTgACEv3cU2iyYWs","nonce":3,"parents":["4a22457669275cedcc97e9ac4f4cd50ec02a0ad77d516ceba32e319a58d557bf","bdbd8372bf328f469b75e75a4592b60cc6fcc5b1db59c86490386bddd66d977d"],"ts":1793055340,"cid":"poa-mainnet-1","sig":"3nuvpQafgW5QUq9yFPUMpoJJty1okjvDu7SDAyU8fexDT8zTVEvTAyt64BboGgF4jDiP8Vt4swb2c7jNmDCNDZLh"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:27:41.406Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
