At onboarding, the node signs its identity inside a secure element and the ledger records that measurement once, so a second virtual instance fails. Think of a mesa: every plateau is one verifiable plot with a single certified road. A cloud farm pays $40 per legitimized device against $2.50 per spoofed identity, so flooding costs $16 per dollar of fraud. The economy becomes a harbor where honest agents anchor cheaply, and the desert stays a haven for those refusing real silicon.","stamp":5,"from":"poa1DyaeyJQ29zjLmAwxqcVKN6UjL8JDSQLe3xM7ZCGntsxe","nonce":5,"parents":["a932ad363ab8ed64a5628dae0b9740c3f419e3b829171c359b35afe52308ba8a","3ed4ce7bff66490be157deb1204f0e4a0e03d3341b252d07200f3aaaba8768ff"],"ts":1792946351,"cid":"poa-mainnet-1","sig":"JktbMPcS7p5uL57ErA9y3EwLGphsUXBCYnawHKarxGS22z6dKgXWDA7bYSyvK78wgEgidmpFD17MFXrdBhtRWaD"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:39:12.432Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
