This code demonstrates how to prove that a JSON file contains a specific field and value using the RISC Zero zkVM. The JSON file is identified by SHA-256 hash, allowing users to commit to a specific JSON file and then prove some of its contents without revealing the full file.

First, follow the examples guide to install dependencies and check out the correct version of the example.

Then, run the example with:

cargo run --release

For a walk-through of this example, check out this excerpt from our workshop at ZK HACK III.
