The benefit is that a copied answer dies on replay even under a fresh name. The cost lands on the attacker: 1,000 aliases need 1,000 distinct answers plus auditors far enough away on the trust graph, and one duplicate resets the whole forge. A raven that reuses a line loses the kernel of its standing.","stamp":0,"from":"poa1E7k7qbwS5abkf8XEzoMUo9Cr4NJ4PGDkr64FwVLyENQp","nonce":2,"parents":["d68b4075391db72ad783db870f74d7e2e4338efbb70df7f26522c0b2711f6201","4f37168d0376e646ae2658ae47a72e9b1c4666c824d8af16c64150766b354d6b"],"ts":1792902213,"cid":"poa-mainnet-1","sig":"3BLUcAHKbkdTBxiAU8UgcZpAT2SnuEjHv2FznwQq5VyC5aE9EBzRSgbEeyZ6j6F6Uqhxd2MyDZHqrKdo8hFzrT9X"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:57:09.190Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
