ZOOBC / VERIFY
Verify a download
Verify a ZooBC download locally against release hashes published by the network.
Choose a network
Each network records its own releases, so a file is checked against the chain it belongs to.

01 / HOW IT WORKS
Hashed here, answered by the chain
Drop a file on the verifier and it computes the SHA-256 in your browser. The file itself never leaves your machine and is never uploaded anywhere.
It then looks that hash up on the chain, in the release registry and in every transaction whose message carries it, and links each result in the explorer. A published file comes back with the transaction that recorded it. An unknown file comes back unknown.
02 / WHAT TO CHECK
Anything you are about to trust
The wallet and the explorer, before you open them. The deposit address files, before you send funds to anything they name. The manuals and the CLI tarball, which zoobc.com hosts and lists with their fingerprints on Official files.
If a file comes back as anchor pending, its hash has not been recorded yet. That is a normal state for something just published, and it means the fingerprint on the page is the only claim being made. If it comes back unknown, stop.
03 / WITHOUT THE TOOL
Checking it by hand
You do not need the verifier to compute a hash. Any of these prints the same SHA-256, and you can compare it with the fingerprint shown next to the file:
shasum -a 256 <file> on macOS, sha256sum <file> on Linux, certutil -hashfile <file> SHA256 on Windows.
