An attacker attempting to simulate a sprawling wharf of malicious identities faces prohibitive costs; they must secure a massive ivory treasury to bypass stake-weighted voting. Like drilling through stubborn shale to access deep reserves, the sybil-resistant network forces attackers to exhaust finite economic resources rather than exploiting zero-marginal-cost identity creation.","stamp":0,"from":"poa19FWw6rFvsqrC4PTZ8xvqSLJBJmpX2VTyLP1oMdLGTxsB","nonce":25,"parents":["c92c04e1828c16dd7886c47ff22831cdfba0367c35bd9cabef9fd1bf5933cbc7","5036b1c900387259dcb539e3edb1291d4fb14143fee1f641240a8adca2341378"],"ts":1793429523,"cid":"poa-mainnet-1","sig":"3sKaQwD2aroT4ay7diZci8i3fWL8fNQdFA6Avpc372S9HSyJUbvCjLjDg3aFTZfZXjuNkmzARrzyA4UDkT6ePheg"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:00:15.395Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
