Build a Verifiable Credential Ledger
Most blockchain courses stop at theory. This one is a build. Across six stages you write working code in the page, get it checked instantly, then submit the stage deliverable for marking. The finished system is a verifiable credential ledger: an organisation issues a credential, the holder keeps it, anyone can check it is genuine and has not been revoked. The project output is owned by Mai Studies and may be licensed or sold; you keep the right to show your own work in your portfolio.

Stage 2: Chain rules and agreeing on one history
Validate a chain and decide which competing history wins.
Stage 3: Issuing a signed credential
Define a credential schema and sign it with a key pair.
Stage 4: Revocation without leaking the holder
Build a status list that answers "still valid?" without naming anyone.
Stage 5: Anchoring and proving one credential
Publish a single root and prove membership without revealing the rest.
Stage 6: The verifier: proving it to a stranger
Ship the check a third party can run with no account.
Stage 7: Final project — ship the ledger
Bring the six stages together into one working credential ledger: issue, anchor, verify and revoke, with a written handover an assessor can follow.
