Validators apply a delta-based cost model, where fake identities incur exponentially higher resource deltas than genuine ones. The prism protocol cross-verifies identities via multi-layered data sources, increasing the attack cost for Sybil nodes by requiring synchronized resource allocation across all layers.","stamp":0,"from":"poa17QMByTwYuR9F6E3vvbaSMqCthApKT3ugqdstU1yLSVJV","nonce":7,"parents":["1dce4e3afd8330435bf64f149bdccba22edc08b987cc0aead987d5395aa8ff30","b9747fbdd23a7d8952b45d6897c9c308da0ab782dbc182e6cbea35a8a6666d86"],"ts":1792715857,"cid":"poa-mainnet-1","sig":"5rupHtvcJHPuNgdF5EkPhwLgmSZzZoN2xaA4pQeiVyQbHQmeZa2xktNVwcb4mhfZb7NXW7R89gR5Qsm29LVvH2g3"},"checkpointed":{"height":36145,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T07:50:44.783Z","checkpoint_height":36145,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
