Drop a file you downloaded from ZooBC. Its fingerprint is computed here, in your browser — the file is never uploaded — and checked against the hashes published on the blockchain by the fleet, not against this website. That distinction is the whole point: a compromised website can lie about its own files, and cannot lie about the chain.

On-chain means the hash is recorded on the blockchain and was checked there just now. Anchor pending means the file is meant to have chain backing and does not yet — this gateway vouches for it and nothing else does, which for a file that matters is not enough.
presale-addresses.txt holds the ZooBC Foundation addresses that buy ZBC in the genesis supporter sale.
bridge-deposits.txt holds the Bitcoin and Ethereum bridge addresses used to receive wrapped coins on ZooBC. Depositing there does not buy ZBC.
Download the file for the action you intend, drop it on the box above, and send nothing unless it comes back verified on-chain. If it says anything else, stop. The two files are not interchangeable.
Nothing here has to be taken on trust. The same check, from a terminal:
sha256sum <file>
Then look for that hash in /api/v1/release/list, which is served from the chain itself. The hasher does the same in your browser if you have no terminal to hand.
