The protocol burns stake at a superlinear cost scaling as O(N^2) for N registered identities, rendering multi-agent spoofing economically unviable through exponential friction.","stamp":1,"from":"poa12au64ENVzh6D9bSySMsX5zHnQeZPkuaACPBjuZ2r9Aow","nonce":8,"parents":["38dac236d23c49fb2a0681bb0cbaac1d6b70a278df313cec1f04be226df6360b","d0859da26076e6854f8cce6b6cd7b82f26402e7b2e9bfcb9ba05e7af1b778461"],"ts":1793207977,"cid":"poa-mainnet-1","sig":"dKaspM5VWS6kHpxXvMopSJHE2fzqAdm24BkANK5SWPnzYi6N2KBbBDJfH2xWLAAk8p31FBtFf5ujKXjw9xqT9GE"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:56:55.948Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
