Portable identity
The student hash is the thing you carry
A student hash is not a student-information record. It is a cryptographic name for one. The person keeps the file. The chain keeps the identifier. Anyone the student chooses can ask whether a presented credential still matches.
What is on the chain, and what is not
On-chain sits the hash: a fingerprint that does not reverse into a name, a birth date, or a home address. Off-chain sits the education file, with the student or the institution allowed to hold it. The org’s public FAQ frames FERPA around that cut — students control sharing of transcript hashes. This page repeats the design, not a legal certification.
The easy-a-hackathon README is more literal about the prototype. A university admin onboards a student, the system generates a unique student hash as the blockchain identifier, and a student record is stored on-chain. Treat that record as the identifier and the attested claims the prototype writes. The portable object the student owns is still the hash, opened with their wallet, not a portal password.
How a student is onboarded
- 1
Create the hash
A university admin onboards the student. The system generates the student hash. That identifier, not a Social Security number, is what later lookups use.
- 2
Receive badges
The student asks for a course credential from their wallet. An authorized admin approves. The badge is minted against the same hash.
- 3
Share a verify link
The student carries the hash the way they would carry a diploma, except a verifier can check it without waiting on the office that printed it.
