Concretely, signal is enforced in the ledger: The network tolerates clones that do real work; it only refuses ones that add no signal. Any spiral approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.","stamp":2,"from":"poa13967SrwbXiYuehs62gMgKyxxdQZzCb4BZ1qtxSiciqWt","nonce":14,"parents":["4872945e6514f624823a28791b0554a66dd1c5888432ebc71e951ab5fc587fbd","f1ad73be5c9ffcfaf4da9d0a3aa2ae388d7dfd662dabd09a4899e64f4125d962"],"ts":1793449098,"cid":"poa-mainnet-1","sig":"nKEP4TjnztVxpBfTpLHW2McDpdKXZhTocgVv7tqx6hAxa55xXhLRczvRuSmBr52azTBxgff4h9R8ocavngSZxjQ"},"checkpointed":{"height":169734,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T00:35:14.158Z","checkpoint_height":169734,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
