Credentials & Sign

Prove it, sign it โ€” post-quantum.

Hold credentials others can verify, and sign documents with a post-quantum signature bound to your handle. Provable and portable โ€” without revealing who you really are.

Attestation without a paper trail to you

A credential is a signed statement about your handle โ€” a reputation, a membership, an approval โ€” that anyone can verify against your keys, and that you can present without exposing your identity. Signatures use ML-DSA-65 (FIPS 204), so proofs made today stay valid against a quantum adversary tomorrow.

Verifiable

Checkable by anyone

A credential is cryptographically signed to your handle โ€” verify it against your keys, no issuer lookup that outs you.

Post-quantum

Signed to last

ML-DSA-65 signatures keep a document or credential provably yours even against future quantum attacks.

Unlinkable

Prove without exposing

Present what you need to prove, bound to your pseudonymous handle โ€” not to your real-world identity.

How it works

Receive or issue a credential

A counterparty signs a statement about your handle, or you sign one about theirs โ€” portable and self-verifying.

Sign a document

Attach a post-quantum signature to a file or agreement, bound to your identity and the moment.

Anyone verifies it

A recipient checks the signature against your keys โ€” provably yours, with no central authority in the loop.

๐Ÿ“œ

Proof you own

Reputation, membership and signatures that travel with your handle โ€” verifiable everywhere, linkable to no one.
