3. Blockchain :
 A digital database containing information (such as records of
financial transactions) that can be simultaneously used and shared
within a large decentralized, publicly accessible network.
Smart contract :
 A smart contract is similar to a contract in the physical world, but
it’s digital and is represented by a tiny computer program stored
inside a blockchain. More specifically a smart contract is a piece of
software that stores rules of an agreement, automatically verifies
fulfilment, and then executes the agreed terms.

4. Why Smart Contract?
 Smart contracts are designed and implemented within
blockchains, and therefore they inherit some of the
blockchain’s properties
 They’re immutable, which means a smart contract
can never be changed and no one can tamper with
or break a contract
 They’re distributed, which means that the outcome
of the contract is validated by everyone in the
network, just like any transaction on a blockchain.

5. Smart contract Benefits
 Transparency
 Direct dealings with customers
 Resistance to failure
 More trust
 Fraud reduction
 Cost efficiency
 Record keeping

6. Use Cases
 Banking
 Health Care
 Supply Chain
 Legal Issues
 Real Estate
 Internet of Things Networks

7. Student Info System
 SIS uses Blockchain technology to store & retrieve the Student personal
and Academic data.
 We used smart contract concept to store the data on the Blockchain.
 We created a test Blockchain network on the local machine to the test our
system.
 We stored the data of a student on every block in the test Blockchain
 The data on the Blockchain is more secure and very difficult to hack or
tamper.

8. Technologies & Libraries
 Ethereum Blockchian
 Node js
 Solidity programming Language
 git
 Remix IDE
 Ganache
 Testrpc

9. Working System
Creating Test Blockchain :
 We used the Blockchain that is created by Ethereum Organization.
 To create a test block we used Ganache library.
 We created a test Blockchain with 10 blocks in it.
 Every block can be accessed with the private keys.
 Test Blockchain is running the local machine so that we can use the Blockchain
without any real money or Gas required.

10. Working system
Deploying the Smart contract:
 We deployed the smart contracts on every block of the test Blockchain.
 We created a simple set of rules to store and retrieve the data in the test
Blockchain.
 We used solidity programming language to write these smart contracts.
 We did our operations (Data entry & retrieving) and transactions using Remix Ide.
Add & Retrieve data from the Blockchain :
 Every Operation on the Blockchain requires Virtual gas to perform the operation.
 We used Remix Ide to add & retrieve the data from the blockchain.

14. Retrieving Data from Blockchain

15. Future Work
 We want to create a DAPP that uses these smart contracts to manage the whole
college system.
