The inference runs inside an enclave that produces a 252 bit measurement of the code and data it executed, and the answer is accepted only if that measurement matches the published build. A farm that substitutes a inexpensive script for real reasoning cannot produce the quote, so it forfeits for the enclave anyway and gets nothing. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":4,"sig":"49wF8BtoKbzActs6ncgGU2mVPSD5GtmBS28duNGcdK9ptZv6efpaLs43McLAiFxDa3ZKGEpbun8WUqF5WnwTNvAU"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:56:54.225Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
