Don't trust the record. Check it.

Every released pick is sealed into a public chain the moment it's released. This page downloads the whole chain and recomputes every seal in your browser, so you don't have to take our word for anything.

How the seal works

Sealed at release

When a pick is released, we publish its fingerprint: a SHA-256 hash of the pick's details. The fingerprint is public right away; the details stay private until the game is graded, so members get what they pay for.

Revealed once graded

After the result is in, the pick's details are published next to its fingerprint. Anyone can hash the details again and confirm they match what was sealed before the game, so nothing was edited after the fact.

Chained together

Each fingerprint includes the one before it. Removing, reordering or changing any past pick would break every fingerprint after it, and this page would show it.

At the end of each day we also record the chain's latest fingerprint as a daily anchor (below), so you can compare today's chain with a fingerprint you saved earlier. To check it without this page: download the JSON, and for each entry compute SHA-256 of the previous hash, a newline, and the entry's canonical text. The first entry starts from 64 zeros.
