A compass that only points north when the maths agree

Every node ahead of you is one public phase-gate receipt. Every thread between them is a SHA-256 link. Nothing here is decoration: the constellation is drawn from the chain document, and the chain is re-derived from scratch by your own browser, in this tab, with WebCrypto.

We do not ask you to trust our verdict. Scroll, and watch the instrument earn it.

بوصلة لا تشير إلى الشمال إلا حين يتفق الحساب. كل عقدة إيصال، وكل خيط رابط تجزئة، ومتصفّحك هو من يعيد الحساب.

The chain starts from a published word

There is no secret seed. The first link chains from the SHA-256 of a genesis tag that is printed in the document itself, so anyone can start verifying from link one without asking us for anything.

One number stands for the whole history

Fold every link together and you get the head. Change one character of one receipt and the head changes. That is the entire claim, and you have just checked it without running a line of our code.

What this does not prove: that history was never rewritten. A chain served next to the data it commits to shows internal consistency at this moment. It becomes tamper-evident against us only once you write the head down and come back later.

Break it yourself

Nothing leaves your machine. The edit happens to the copy in this tab, then the same verifier runs again over the changed bytes. Watch the break light up, run downstream, and take the needle with it.

Bring your own bytes

The most honest way to run this instrument is to not let us hand you the data. Fetch the chain yourself and paste it in; the verifier below is the same code either way.
