Blockchain Evidence for Overseas Study Archives
Your archive fingerprint is written to the blockchain once and verifiable for life. Anyone can verify online with a query number or evidence hash; archived content cannot be altered.
What is Blockchain Evidence
Blockchain evidence writes a unique hash (SHA-256) of your archive onto a blockchain. Once written, on-chain data cannot be altered, and anyone can confirm the archive has remained unchanged since it was notarized by comparing hashes. CSCSS never puts raw archive content on chain — only hash fingerprints, protecting your privacy.
Ant Chain · Archive Data Evidence
An Ant Chain channel carrying three core categories of archive data — identity, academic scores and entry-exit records. Only hash fingerprints go on chain, publicly verifiable.
Ant Evidence Chain
An Ant Chain (TWC) notarization channel that issues a unique on-chain identifier (tx_hash) and block height for each material file — file-level evidence, verifiable item by item.
What is Notarized
Identity Information
Academic Scores
Entry-Exit Records
Material File Hashes
Prerequisite: the evidence application is approved and the main education record has been graduated for at least 7 days. Only hash fingerprints and timestamps go on chain — raw archive content is never published.

FAQ
Is verification free?
Yes. Evidence verification is free for everyone — enter a query number or evidence hash to verify.
Will my archive be public after going on chain?
No. Only hash fingerprints are stored on chain; names, scores and other raw content are never included. Verification only proves the archive is untampered.
How long does on-chain submission take?
After payment the application enters manual review; once approved and the 7-day post-graduation requirement is met, submission is scheduled. Hashes appear in your member center afterwards.
How do I verify a piece of evidence?
Enter the query number (shown on the report page) or a 64-char evidence hash on the verification page; the system compares it against on-chain records.
