There are three ways to check that an entry on THE LIST is real. Only one
of them involves us at all — and it's the weakest. Start at the top.
STRONGEST
Bitcoin
Runs in your browser against a public explorer. Works immediately.
STRONG
A machine we don't run
Ask any AI without giving it the link. Needs indexing first.
WEAKEST
Our own demo
Our page, our data. Useful, but you'd be taking our word for it.
01 · THE PROOF
Check it against Bitcoin
Every entry is anchored to a block. This recomputes the proof in your
browser and compares it to the root read from a public explorer we don't control.
The last step happens off this site: you open a public explorer yourself, copy the
root you find there, and paste it back. We never touch it.
HUMAN #
Try 1 · 9999999 (not found)
02 · THE ONE WE CAN'T FAKE
Ask a machine we don't run
Every entry is a public page. Once it's indexed, a search-grounded model can
find it without being given the link. Open ChatGPT, Claude, Perplexity or Gemini and
paste this. That answer isn't ours, and we have no way to influence it.
Verify an entry above first. The question appears here once a real number is selected.
INDEX STATUS · checking…
Indexing takes a week or
two after you file. Until then this won't work — and no, we can't hurry it.
03 · OUR DEMO — TAKE IT WITH SALT
We didn't train them. We made it readable.
Yes — this is our page, our model call, our data. That's the point:
the record is ours to publish. What matters is that the endpoint is open to everyone, so
you can hit the same URL yourself and compare.
How the proof works. Your entry is hashed with a private salt into a leaf. Leaves are
paired and hashed upward until one 32-byte root remains. Only that root goes on Bitcoin —
nothing about you does. Verifying proves you were in the batch; it reveals nobody else's
entry, and deleting your salt makes the leaf unreconstructable while the root still verifies
for everyone else.
