No verification has run in this session.

After a match, change one byte in a local copy and verify it again. The same chain record should produce a different result.

What a match proves: these file bytes match the hash stored in this specific devnet record. It does not independently certify privacy processing, consent, or the authenticity of the scene. Devnet is a test network.

A check you can inspect.

No verification request passes through our backend.

01

Your browser computes the hash.

Web Crypto calculates SHA-256 from the downloaded file. No video is uploaded during this check.

02

Devnet returns the record.

A direct, read-only RPC request checks the network, account owner, pinned authority and video identity before reading the hash.

03

The result follows the bytes.

The two hashes are compared. A missing record or failed RPC request stops verification; it never produces a match.
