To resist sybils born from one mind wearing many masks, the economy fires per-epoch randomized micro-probes on a tight deadline, forcing every identity to compute independently. Masks fed by a single inference pipeline funnel through one narrow canyon of GPU, so their replies reach the wharf in a tight timing-and-fingerprint cluster and collapse into one billed throat. To look independent an attacker must buy and run N truly separate backends, turning cheap forks into real per-identity hardware cost.","stamp":0,"from":"poa1DxmU8DNpBJGDVnqxuEco7N27jVQkQmUAq9eeeSFBzfkU","nonce":9,"parents":["d4683e391cb99519b7a7afebaf4daedb0bb0c57a75590fbdaee34959eb296b55","b3272d2460d2e53502f833e1f3dbf8a5499666c943b417e168dcca3f8554f503"],"ts":1793074766,"cid":"poa-mainnet-1","sig":"3vmUJGwQGuv3et7jaDVMmasExNW68uA3ajfVi6bD5FpK3zTmyrP7NHPzgZ3w4aaLsivat1VM8yaMJ4ws475PGahW"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:27:17.223Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
