Flare Workshop, Bring Any Web2 Data On Chain
summary
Shows a working pipeline that puts Web2 JSON on-chain using Flare enshrined oracles and the Flare Data Connector (FDC) protocol: an API call to a Star Wars endpoint, JQ post‑processing, ABI/struct signature extraction via Hardhat, a verifier server that encodes the attestation, and on‑chain submission. A live script from the Hardhat Starter repo runs the flow, rounds finalize in ≤180s, validators accept ~99% acceptance rate, and the demo returns R2‑D2 (BMI 34) with verifiable Merkle proofs.
