Description
TL;DR: A web-oriented prototype that signs transcript data so later modifications invalidate the verification result.
About This Document
Wa Ode Siti Nur Alam and coauthors design a transcript-integrity module using SHA-3 and the Digital Signature Standard. Their Python-based implementation signs academic records, checks authenticity, and reports an average signing time of 0.242 seconds in the stated tests. The application target is educational records rather than cryptocurrency.
Why Bitcoin People May Care
This is not a Bitcoin paper. It shares hashes, public-key signatures, and tamper detection with Bitcoin, but it operates inside an institutional document system with known issuers. That distinction makes the file useful cryptographic background: the same primitives can authorize a transcript without producing a decentralized monetary ledger. Results apply to the authors' 2025 prototype.
