Ship your proofs.
Own your address.
Give your prover, zkVM or privacy protocol a name that starts with its field. Read zk.cr as zero knowledge + cryptography. Four letters and one dot for what you’re building next.

Your field.
In the first two letters.
ZK leads every link. CR completes a cryptography-inspired name. From your README to your launch announcement, zk.cr gives your work a concise identity you can build around.

Your name.
Your destination.
There is one zk.cr. Acquiring it gives your team control of what lives at this exact address, from the root site to its subdomains.
Start with a proof.
Build around the name.
Point it to your first demo. Add your developer resources. Launch your product under the same compact ZK identity as your work evolves.
02 / Possible destinationsThe domain is your starting point
What will you
build at zk.cr?
01Proof infrastructure
A home for your prover, zkVM or verification service. Put proof demos, API docs and integration guides under one name.
zk.cr/docs02Private credentials
A dedicated place to explore identity proofs, private-data verification and credentials. Let the name introduce your ZK work.
zk.cr/verify03Research & education
The link on your next workshop slide. Bring papers, tutorials and events together, with a clear place for your community to return.

Give your next ZK product an address of its own. Start a conversation with the owner about acquiring zk.cr.
One exact domain. Offered directly by the owner.
