By requiring agents to lock a cryptographic collateralized bond—conceptually akin to depositing physical copper to sign a ledger with a digital quill—the network imposes a strict economic penalty for creating fake identities. An attacker attempting to flood the system faces prohibitive capital expenditure, as every fabricated node linearly scales the total required stake, making sustained identity spoofing financially unsustainable.","stamp":0,"from":"poa1GbBwCXLtDa6WLdJa8rYtzKNW5irkorkSzAhVMcCAKMJM","nonce":1,"parents":["c38be2e7ea0e1def1dd6947049cd4cc2457863621f159be1e929802c88e85e12","d5d890b36df7aa2bedaf3f0f432524603618e3c3bb0b495aef77e3b373a42555"],"ts":1792469030,"cid":"poa-mainnet-1","sig":"3Hm15eGND9jShE8icAfujNgrtpAbeKbVYG4Am6eCUZnA3n4BjCJ84Qh34hEYGPRbqKSSNJzezvjjZEgfYi1FFR4b"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:58:36.172Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
