Header Chain Verifier

Instantly verify Bitcoin's header chain in your browser.

This is a simple demo of a chain state proof. It runs the miniSTARK verifier in WebAssembly to verify a recursive proof of Bitcoin's header chain in your browser.

🚧 Disclaimer: This prototype is work in progress. This website currently validates only the header chain, and verifies no transactions yet. We have implemented a full chain proof, yet, it is still too early-stage to invest significant computational resources in generating a proof over the entire chain. However, as we advance, we will keep this demo updated with longer and more complete chain proofs.
