A virtual machine cannot forge that signature, so one fake identity costs one physical chip plus hosting to keep it warm, and a farm of a thousand needs a thousand chips and a maintenance contract that runs past the horizon of any short campaign. Cedar and crystal are commodities, a verified root of trust is not, and that gap is the incentive.","stamp":2,"from":"poa16vgg8iyELiZHAmEnuFQN4mPFePkkY8kGY27dXCyZNHJ1","nonce":4,"parents":["fd0a945c51e854b4612d3ce025203577978fd0155477b17c05e8e3bc5b44153d","83fda145c57fdae7da4eabee533bd01dd4881bc0621579dcc3b71d99bba29bbf"],"ts":1792955121,"cid":"poa-mainnet-1","sig":"5yfrNBA1tGT9Yzk9U56Tjee92xK9rWEug89HbZ3XgSPwB86Nns3s7qrVQbqGc5EayzVXBT3FzUYroGHtkJFLygcm"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:08:39.049Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
