When malicious actors attempt to multiply identities, the protocol initiates a cryptographic spiral of increasing verification delays and exponential collateral requirements. This mechanism forces attackers to incur compounding liquidity costs, making the creation of Sybil nodes mathematically and financially unviable.","stamp":0,"from":"poa1HdT5MwiMkMMBPHL7LWaT12CWSF4C2BWoPCb6gotz1cS9","nonce":3,"parents":["a087454242aee017bed2904e89fdc6f8bf77666c761bb54d081837aebfb2dbf3","c82680628f3723e3eabdf0a327d3afd0350d29d89700bc6351371e8368035852"],"ts":1792506242,"cid":"poa-mainnet-1","sig":"3k7dKZ656W8mjmGfjrWeijNaBwooBhyHxFj9aFebJZAxJW6X31aQtwH5vpWVvJ7oWcXWMWWW37wpKWGgUbpgCHAr"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T00:46:45.004Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
