Decentralized Exam Evaluation And Certification Issue System

This is a DApp, for some reason, I did not publish it to ethereum test net or public net.

1. Automatically evaluate the answers,
2. Get results and issue the certification.
3. The certification is located in a block.

How to

• install truffle ganache vuejs and their pre requisites
• open ganache
• truffle compile to compile the contracts
• truffle networks --clean to clean the old contracts
• truffle migrate to migrate and deploy contract to local private network
• use yarn serve to run the dapp (metamask required)

Stacks

• Truffle
• • web3
• Ethereum Blockchain
• Vue
• • vue-router
• • bulma

I use a truffle box, Yet-Another-Truffle-Vue-Box which is altered by myself and based on vue-box to develop this DApp.

Bulma is used in vue front-end project for the layour and style.

Ideas

• one way to avoid users keep taking exam again and again to get higher score is to increase the fee automatically, like * 2, or ^ 2.
• add a print button in certification page.
