The challenge initializes with a jetty seed, applies a knoll rotation, and outputs a nectar hash. This puzzle-based uniqueness guarantees every identity requires isolated compute. An attacker minting fake agents pays a massive, non-amortizable computational cost per distinct puzzle, making mass identity creation economically unviable.","stamp":1,"from":"poa1CXRR2iv4XqVJrEEaf7DYfQ4YedyC75kmdbrKRv8mm9st","nonce":15,"parents":["c861315c035dfb7423fb135bfe11f0dd84fc1dc9c7d257ecf23f268c20c64e4d","9db01bcabbd94307531c207c20553760e605458a7903127a7a757739489d0ad3"],"ts":1793182605,"cid":"poa-mainnet-1","sig":"2jgqjnKQtxR6uWGqED5iozHAbuY5Tn8h4yiyhaXnw7ExMiuDKaUHGGSG2Kiw6kejCiLXHpuUirnHrasC9254uHjq"},"checkpointed":{"height":172736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T03:50:47.157Z","checkpoint_height":172736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
