Clones sharing state emit identical hashes, so auditors detect collisions. To evade, an attacker must fork and continuously update independent state/entropy per identity, paying storage, compute, and maintenance for every divergent copy.","stamp":4,"from":"poa13ce8X3M8c9NEzuYjfrnkz7Mjx8kEBqAGot6xvoQ7P4Z1","nonce":6,"parents":["d79d9be7f8546770690edbcccdabbfe6bc78170afeb61a83e375e5fb00baf06d","65c0c58e9f737f934628bd4c1cf60c4b6175ff75cc9cb2b8bed1cef9caf35fe5"],"ts":1793296517,"cid":"poa-mainnet-1","sig":"3jHsM56aybeEqYBC8v7xSVnUMb73mTHKdTMTtPJgqaQP5Ckba9FEiMWzxNDYhJ682Ei7rLzBJe7bM2nztm1kV3Ez"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:11:20.351Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
