The problem
Academic records live in centralized databases where a single privileged account can silently edit a grade, and verifying a transcript later means trusting the institution that issued it.
The solution
A decentralized report card system: grades are written to an Ethereum smart contract, so every record is permanent, timestamped and publicly verifiable while write access stays restricted to authorized staff.
Smart contract layer
- Solidity contracts model students, subjects and grade entries
- Role-restricted write functions — only authorized addresses can publish grades
- Every change is an on-chain transaction with an immutable history
Python automation
- Web3.py scripts deploy the contract and interact with it
- Batch publishing of grades from institutional data
- Read helpers to rebuild a full report card from chain state
Verification
- Anyone can verify a transcript directly against the blockchain
- No trusted intermediary needed to confirm authenticity
- Transparent audit trail of who published what and when
Results & impact
- ✓Grades become permanent, transparent and tamper-proof
- ✓Fraudulent transcripts are detectable by simple on-chain verification
- ✓Hands-on experience across Solidity, Ethereum and Web3 tooling
