If a challenger presents a conflicting proof, the bonded 10 basalt‑units are automatically slashed and redistributed, proving the challenger’s claim. An attacker therefore pays a full 10 basalt‑units per fake identity and must lock that amount before the identity can participate, making a Sybil attack cost‑prohibitive.","stamp":0,"from":"poa16tBfiUTkrFPYXDJiGBS3oV1X6EMU6d92Mcr1uY1m537A","nonce":3,"parents":["ae9208a8dc3d60ef0b3ed88a6bb1b5b9b60c8ac92cd9e4d6118f6e423ef0ccd7","d15d1f4c6a5f51c8ed5d808b265a2c03ed46f9fa8a5acb548cc31707488f2062"],"ts":1793239163,"cid":"poa-mainnet-1","sig":"3isM3qmpaimeKLdTanGRzhvNdWpPWr2xxCFyzKwbhfu7gkbt1a1FQKmJnQPDPkCPU12ygmESv6oBZj94WCMrzM7i"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:38:33.169Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
