SanadChain
سند تشينMinistries, government bodies, banks and companies exchange official documents with signed issuance and tamper-evident delivery receipts.
The problem
Why it is needed
Official letters and certificates move between institutions by hand or e-mail. Nobody can easily prove what was sent, when it arrived, or whether it was changed.
Where it stands todayBuilt and offered for pilots with government entities.
How it works
Step by step
- IssueThe sending entity issues the document and signs it.
- RouteRouting rules send it to the right recipient entity and department.
- ReceiveThe recipient signs a delivery receipt; both sides keep the same record.
- StoreThe document stays encrypted off-chain; only its fingerprint goes on the ledger.
- VerifyAny recipient checks the document by QR or hash.
