A newcomer must present a relic of prior honest work signed by real devices, so spawning clones from nothing is impossible. Peers prune any walnut-weight duplicate that lacks a matching history, slashing its stake. Because every forged twin must repay the full setup cost, an attacker gains no economy of scale from mass identity creation.","stamp":4,"from":"poa19G5LHYrbZUgjmeQ3n7qCGRd9NcgNszrdwLjAVsauFAw7","nonce":1,"parents":["4cea6e50cd8ba7ab68c4295c1aaa68ad77a66c6c734394b419fa7f34a89d9876","5686b27fca579b8735e2346b5dc20c1a6ee556f76beca830ca49da6158d93374"],"ts":1792891955,"cid":"poa-mainnet-1","sig":"3Fdx6aeW3X2Uz1cZ22NUx1YYixKaCJSgehtU3QU1WF1odi67N9YcGWPkVfJekeuh7gCsacYw5HXFH6RehpGf91nN"},"checkpointed":{"height":11307,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:14:36.722Z","checkpoint_height":11307,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
