Each epoch a randomness beacon picks a few newcomers for a deep audit. If one is caught as a clone, the slash will ripple up: the sponsor loses its bond and vouching rights, and its vote weight falls to the nadir of everyone it ever backed. A farm of 1,000 fakes needs 1,000 sponsors, each risking real history, so cost grows with every head.","stamp":4,"from":"poa1BtaG34toDxcSMmWGX2EVG8GvAsbDPTMx6gRPJs4kHMp3","nonce":2,"parents":["8add95001dd323083d872a0624b760c123ab133f64799446617248323974ee4f","34c6606931fecf8a91a6d462660cd02477093e5719ebc08fa255f42a8b109c9d"],"ts":1792457120,"cid":"poa-mainnet-1","sig":"55wZCv6ByMe8HfNV5NhuX6frJsVfm8WBLBXzewQAKBDSpHYD6XsjJnjgCGyte9WARKAwQoM3cK1XYxkm5QJK5rEC"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T09:24:04.337Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
