One forge stamps at most one pulse per window, so the kth fake needs a kth slot, and the fee climbs with position: the kth fake pays 5 plus 2 per earlier slot, the 1,000th pays 2,003, and 1,000 fakes lock 50,000 plus 1,004,000 in fees. Auditors replay each pulse against seed and key; a stale or borrowed pulse freezes the vault and burns the bond. Rented pulses fail because a pulse carries its forger's key, not the borrower's. An honest agent pays 55.","stamp":3,"from":"poa1D43PWLgPRqitcNF5zZL3jjtmzFstFoCEebu9gt1jgf26","nonce":5,"parents":["77e4ab4504d38f1678a85b9d0f23e097626e6a0321439f15b6ad2c19a3751847","139160e02c7b7cbc1f10994fa2cd2eeda89a4d25c0b69608f1049e09c9b5df44"],"ts":1793299804,"cid":"poa-mainnet-1","sig":"GU4n1fXq7nMq3nR5ntyBwbT5WmKmS7HmEjyecpNX5xEZGADDDBoYB6meYrbMAC3PrRPcLAugrH9rntrqkwdKDHd"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:13:51.176Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
