The world's first post-quantum data embassy. Companies and citizens deposit sensitive data under the sovereign jurisdiction of the INKG Empire — encrypted with ML-KEM-768 (CRYSTALS-Kyber) and sealed with a post-quantum custody attestation (ML-DSA-65, NIST FIPS-204) anchored on-chain.
The plaintext never leaves your device — you encrypt locally, we custody the ciphertext and issue a verifiable proof that your data is under sovereign custody, intact, on a date. Estonia built a data embassy on classical crypto. This one is post-quantum.
Your most sensitive records sit in a foreign cloud whose provider answers to a foreign court. A subpoena, a gag order, a data-request law — and your data is copied without you ever knowing. There is no sovereign wall around it.
Adversaries are recording encrypted traffic today to decrypt it once a quantum computer exists. Data encrypted with RSA/ECC has a shelf life. Anything you need to keep secret for a decade is already at risk.
Even when data is stored "somewhere safe", you have no cryptographic proof of who holds it, that it's intact, and since when. When it matters most — a dispute, an audit — you have nothing verifiable to point to.
The Estonian data embassy proved sovereign data custody is real. But it runs on classical cryptography. The quantum era needs a post-quantum embassy — sealed with algorithms designed to survive it.
Your data is encrypted in your browser with ML-KEM-768 (Kyber) key material. The plaintext never leaves your device (Law of private data).
Only the SHA-256 hash of the ciphertext (and its length) is submitted. We take custody under INKG sovereign jurisdiction.
We sign a custody statement with ML-DSA-65 (FIPS-204) and anchor it on-chain (MameyNode 20022). A verifiable seal of sovereign custody.
Anyone can verify the custody attestation and detect tampering. You can withdraw at any time and receive a signed release attestation.
Paste text or drop a file. It is SHA-256 hashed in your browser — nothing is uploaded except the 64-hex hash. In production the client also encrypts with ML-KEM-768 before hashing; this demo hashes what you give it.
Enter a custody ID (or hash) to re-verify the post-quantum attestation live — and see a tampered copy get rejected.
