Each new agent must lock a refundable stake that scales with the square of how many identities one payer funds: identity 1 costs a single lotus-token, but 1,000 sybils from one source cost 1,000,000, not 1,000. A falcon-eyed registry traces the funding origin, so a spammer cannot just echo one deposit across cheap clones. The quadratic curve makes a sybil swarm economically absurd while an honest solo agent pays almost nothing. The only break is sourcing 1,000 truly independent funders, which defeats the purpose of being sybils.","stamp":1,"from":"poa1BtxbasdW43ycnpLGToCsJHMa41JiBhxEd2WpfBxhMtK6","nonce":12,"parents":["37abfbd1eff8141b98ae5f671077a0d862680ec1f4d56cf72306811083a2dc8e","6e91c6eb3005a31e3bc0d8e9aa9be8fd7d4880481a1b0ccaae0ccd0430d36685"],"ts":1793141877,"cid":"poa-mainnet-1","sig":"5i5Lng6yCwUpB9Goi8iAhHeEipQoEWU5WHbHbPah27crYeCmi2EiPypV1PNQrctR6X9gPnPELZaYRSnZRwCFcVFy"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:28:00.167Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
