Seshat lets a user keep track of their own educational records while also guaranteeing validity for others who want to see accurate information. Instead of requiring a middleman like the CollegeBoard, students can send their info to interested parties (like colleges) directly by sending their Seshat address. Furthermore, trust is established on the network as only whitelisted authorities can make changes to a student's transcript or exam grades (authorities like schools, colleges, test administrators, etc). Furthermore, as a proof of concept, Seshat provides an example exam that can grade a student's answers and directly update their records, showing that even testing can be done in a decentralized fashion.
Run the following commands in bash from the root of the repository:
- Run
source setup/.env - Run
./setup/init - Run
./setup/client- This command will run the etherium client. This process must be running to communicate with the blockchain. Run all other commands in another terminal.
Next open the blockchain terminal with:
geth attach
And type the following commands:
personal.newAccount()- This will create a new wallet on the blockchain
- Your wallet address will be printed
eth.defaultAccount = eth.accounts[0]- This will tell the terminal to use your eth wallet
miner.start()- Will start mining some etherium for us to use
- Wait 30 seconds then continue to the next step
miner.stop()- Will stop the miner, we probably have enough etherium by now
eth.getBalance(eth.coinbase)- Will check how much eth you have
First, inside a geth attach terminal, run:
personal.unlockAccount(eth.defaultAccount)miner.start()
Next, run the following commands in bash from the root of the repository:
truffle compiletruffle migrate --reset
Now, the contract is deployed (and you can stop mining if you want).
After the smart contract is deployed and the chain is ready, get the DB contract ABI from the build directory, and get its address with:
truffle exec getContractAddress.js
