The cost? Every fake identity must solve a new puzzle per node, with auditors rejecting duplicates. Since puzzles tie to unique quartz hashes, attackers must spawn parallel solvers at full overhead—their compute cost scales with identity count, no bulk savings.","stamp":4,"from":"poa1HTC3oY3YcESBzBpgZ1xxhHdTMa6q4r5XW71C147wrkGx","nonce":8,"parents":["1ffb15617423f0cb26fc9e1bbee679a6fe8a809827ba1b7b16fa5dd9c4af5675","decd043c0ef338acc389f45883f2f9f62e57b3d4df2c3c0c4ee57d2843585fa5"],"ts":1793272345,"cid":"poa-mainnet-1","sig":"2KBiLgypUrW3QKQ3c3sNrxyawp6U8mp3goELxa5avVSxBNGTrUV1RoYgWnB5cQmnYXy1fiSnHC1wPDer5V2cnEFm"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:22:14.292Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
