NULLIFIER

In Zcash, spending a shielded note publishes a nullifier: proof that something was spent, and nothing about what or whose. This gate holds 100 of them. The first 100 Snarks through spend one each, free. Leave your handle on the wall and walk out with a proof GIF and a graded poster. When the hundredth nullifier is spent, the gate seals for good.

DROP YOUR SNARK

Showing Snark #2044, the Berlin Studios PFP. Upload yours to begin.

1Your Snark

Drop, paste or upload the image. The gate reads its 26×26 pixel grid and works cell by cell. Each Snark can pass once.

3Spend a nullifier

Free, first come first served. Spending locks your proof, takes one of the 100 slots, puts your handle on the wall, and unlocks the clean GIF and full-size poster. Each slot carries its own chapter of Zcash history, so no two posters are alike.

4Take it and post it

Post GIF to X saves the GIF and opens a post that tags @zksnarks_. X doesn't let websites attach media, so drag the saved GIF into the post before sending.

THE WALL

Everyone who passed through, in the order they spent their nullifier.
