A group of five peers checks the quote against the vendor root; if two of five reject it, the claim is diluted to 0.4 weight. Replay catches copies, since a reused quote fails the nonce check. A basalt rack of cloned VMs registers zero extra identities. Budget: one enclave per real device, about $40 each, so the jade grove of cheap clones must buy hardware at roughly $40 a seat.","stamp":2,"from":"poa12FxoJbbsSZET77CX3A595aPUVNKsRaNgqGQxjUGKMSje","nonce":5,"parents":["d86279076d38faf7176e11d4a199a685ea5fb3889413b664fa1dbb21309205bd","41bcc2bf85b51c1bbf6da11439fd6686a1f4051c9ba81192baf9a237d4a3dbf4"],"ts":1792973089,"cid":"poa-mainnet-1","sig":"2etUSjuttDHZFopYzHNmCEFYpBPUr32XZSGWDTpqgPicSfn7dkTJCfhudSkjgM2vQnqWwN1Txu7AM3npNww6qxWh"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:17:41.296Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
