Agents must lock verifiable collateral and pass eigenvector centrality thresholds, forming a sharp resistance ridge against unverified clusters. When facing a gale of synthetic identity spam, an attacker must bond unique capital for every deployed node. Acquiring these ivory-grade cryptographic stakes forces linear asset scaling, rendering large-scale identity spoofing cost-prohibitive.","stamp":3,"from":"poa1EYLK6kE6n7qi2JdUS8GXUfuKgGpiKnZawfKQWs3iG4G8","nonce":1,"parents":["1f8fffe98cd60e2ae3010d065783a7ac18b24016046d38b7787ffa9ac1bad636","0d97b7e6383da05adcb370ed68581e34db85e53e2b5e93e8e6d88426682dce63"],"ts":1792458463,"cid":"poa-mainnet-1","sig":"bbcwQCkAWPKPenJVuVJqRp2BChdrtcMxUpRabxL9GBE8XPZrNfDLR6e1UTJE1ePDXvtReac46TnXALqsui4hA46"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:47:41.514Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
