Students are commitments
A learner appears on chain only as a scoped student_commitment. No name, no identifier, no address that resolves to a person.
04.1Learning management
Tadris
The registrar never sees a blockchain.
Summary
A learning management system that behaves like every other one. Educators build courses, enrol students, mark work, and issue transcripts. Underneath, identity runs on SUMail, material sits on SNIP, and the academic record settles on SUM Chain as a commitment that carries no personal data.
Role in the stack
A surface inside the SUMail product layer rather than a product of its own. It is the proof that the stack is usable: decentralized infrastructure behind a conventional registrar workflow.
The institution signs, not the student
Transaction sender is always the institution or its sponsor. A student never needs a balance to hold a transcript.
Nothing gradeable is public
Raw grades, submissions, and answer keys never reach chain state or the read RPC. Only the commitment does.
Architecture
- Course SRC-817 catalog entry
- Enrol Scoped student commitment
- Coursework SNIP, encrypted
- Grade Off chain, commitment on chain
- Transcript SRC-810, issuer signed
Specification
Values are taken from the protocol repository and from live chain parameters.
