Certified Variables & Certified Assets What This Is Query responses on the Internet Computer come from a single replica and are NOT verified by consensus. A malicious or faulty replica could return fabricated data. Certification solves this: the canister stores a hash in the subnet's certified state tree during update calls, and then query responses include a certificate signed by the subnet's threshold BLS key proving the data is authentic. The result is responses that are both fast (no consensus delay) AND cryptographically verified. Prerequisites - Rust: crate (for Merkle tree), (for / ) -…
