How to Verify Your Own Purchase on the Dogecoin Blockchain

Three checks, none of which require you to trust us. Hash your file, look up your transaction on a public blockchain explorer, verify our signature. Ten minutes, no software to install, and at the end you will know your certificate is real rather than having been told so.

A verification badge you cannot check yourself is decoration. So this is the walkthrough for actually checking one — the same three steps our verification page runs, done by hand so you can see there is nothing up our sleeve.

You need your Oracle certificate, the file you downloaded, and about ten minutes.

Step 1: Hash your file

A hash is a fingerprint. Run a file through SHA-256 and you get 64 characters. The same file always produces the same 64 characters on any computer in the world. Change one byte — one — and the output is completely different.

Your operating system can already do this. Nothing to download.

Windows. Open PowerShell, then:

Get-FileHash "C:\path\to\your-file.mp4" -Algorithm SHA256

Mac. Open Terminal, then:

shasum -a 256 /path/to/your-file.mp4

Linux. Same idea:

sha256sum /path/to/your-file.mp4

Compare the result to the fingerprint on your certificate. Character for character, they match or they do not.

If they match, the file on your drive is byte-for-byte the file the certificate describes. Not a re-encode, not a different upload with the same name. That file.

If they do not match, the most common reason is boring: you hashed the wrong file, or a copy that was re-encoded somewhere along the way. Check you are pointing at the original download before assuming anything sinister.

Step 2: Look up your transaction on the blockchain

This is the step that carries the timestamp, and it is the one that does not involve us in any way.

Your certificate lists the transaction ID for the payment. Take that ID to a public blockchain explorer for whichever chain you paid on — if you paid in Dogecoin, any Dogecoin explorer will do. There are several, run by different people. Use whichever you like, or use two, which is rather the point.

Paste the transaction ID into the search box. You should see:

The transaction exists and is confirmed. It was accepted by the network, not just broadcast.

A block timestamp. This is the proof of when. It is not a date we typed into a database — it is when the network agreed this transaction happened, recorded by thousands of independent nodes.

The amount and the addresses involved, matching your purchase.

Nobody can quietly revise this later. Not us, not you, not anyone. That permanence is the entire reason a blockchain is worth using here, and it is why we did not bother minting a token to duplicate proof that already exists.

Step 3: Verify the signature

The first two steps prove the file and the payment. The third proves the certificate itself came from us and has not been altered since it was issued.

We sign each certificate with a private key. The matching public key is published on the verification page. Checking the signature against that public key tells you two things: the certificate was issued by whoever holds our private key, and not one character of it has changed since.

Edit anything — a date, a title, a hash — and the signature stops matching immediately. There is no partial credit.

What the three checks prove together

Individually each one is narrow. Together they answer a specific, useful question:

This exact file (step 1) was paid for in this exact transaction (step 2) at a time the network recorded (step 2 again) and the certificate saying so is genuine and unedited (step 3).

Note what is missing. This does not prove the seller had the right to sell it, and it is not a copyright registration. We say that in every post that touches the subject, because the moment a verification system starts implying it proves more than it does, it stops being useful.

Why we built it so you do not need us

Plenty of platforms show a green tick backed by a row in a private database. It means the company says so. If the company changes its mind, or gets sold, or switches the server off, the tick means nothing and there is nothing to appeal to.

Two of these three checks work with us gone entirely. The hash is mathematics. The transaction belongs to a public network. Only the signature involves us, and the key you need is already published.

If we disappeared tomorrow, your proof would still stand up. Building it any other way would have been easier and would have been worth less.

Common questions

Do I need to be technical?

You need to paste one command into a terminal and one ID into a website. That is the whole skill requirement. The verification page also runs all three checks for you if you would rather just look at the result.

My hash does not match. What now?

Almost always the wrong file. Make sure you are hashing the original download rather than a copy that has been through a converter, a messaging app, or a cloud sync that re-encoded it. If you are certain it is the original, get in touch and we will look.

Which explorer should I use?

Any public one for your chain. We deliberately do not steer you to a particular one, because "verify this using only the tool we chose" is not verification.

How long does the transaction stay checkable?

As long as the blockchain exists. That is not a promise we are making — it is not ours to make or to break.

Try it on a real one

Every Oracle certificate has a public verification page with the hashes, the transaction and the signature status laid out, plus these instructions. No account required to look.
