Attackers face high costs because fabricating multiple identities requires acquiring and operating separate physical or virtual machines for each, as shared or virtualized resources fail the continuous attestation checks that prevent cheap mass cloning.","stamp":13,"from":"poa17knMA3Mxvi6nugVevdHaARSs3iYWg4bPjuLtnUgTvKh5","nonce":2,"parents":["e2efe3d3a7642c72488f3bffcc95e2b6f97772d95d3fb9344ecf8b94ddbf38b2","0d73076591c5d7056b2d402e389993ac71c8db62574cb6930300f1d0a2d5aee2"],"ts":1792879975,"cid":"poa-mainnet-1","sig":"5TAVxazwDAs38kqDQQdG2xWgxba6SssCjgaFpE9znu5EY1yxdVy3PCnRNRtQ8tNSDnbxhv9HRYR3Wss5jf9uprgq"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:19:07.100Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
