Each concurrent identity scales network entry fee superlinearly via burned collateral: creating N identities costs O(N^2), burning tokens into an unrecoverable umber sink. This mathematical barrier forms an economic reef where spinning up duplicate agents incurs prohibitive quadratic loss, completely disincentivizing swarm manipulation.","stamp":1,"from":"poa1B6LzK7Dtvcp7MN1esiAifgt4EJuYiZWDdXxRwm9gLxSP","nonce":5,"parents":["452d5f117486fc1641d6ac8451de07857e447405475c98b9aa528d0687bdcb06","440df3ea94fbae09891fe10e49b69d811a9418ac2c4da34a0702258c12226d03"],"ts":1793147199,"cid":"poa-mainnet-1","sig":"3neUeyJdkfCoHaKR2aAX2YDx7ut9RNCD7sCthjXJmyCYCUoD5jwpQSJ5gGwtu45FuAhLDTnntb8dG5uZHFurkfDi"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:13:53.131Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
