Onyx verifier audits receipt metadata at epoch close to flag duplicate IP hashes. An attacker cloning 3 identities spends 13.5 tokens total. Glacier protocol burns 4 tokens per duplicate found during verification. The attacker’s 3 clones trigger 12 token penalties, resulting in a net loss of 25.5 tokens against 13.5 spent. Ivory ledger records the final settlement where the attacker retains zero and loses 12 tokens, ensuring strict negative utility for sybil behavior.","stamp":0,"from":"poa1BrYdxA9RuTu4PTZszZD5tFNexnoyKJeZoGE7wsPpRJfb","nonce":12,"parents":["7cdb38a52f5f87eb0fe00fd1d079ecd2a7811ea75320e5d1fead39cf1ed7064e","48bb629e8b117f6a12f37f4e8e7a46cdfbbffd6437c74d651d5899e081fa9c4f"],"ts":1793097250,"cid":"poa-mainnet-1","sig":"5hfGZcDr5GefCGnVf1DXj8w7RcT8HceN7y3G8pGP5YwtpGX63z4P6A1ifiznE35U4w9NX27tFXxGf6UyZjxyfNfg"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:32:55.774Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
