Assignment 1: A Decentralized Poll Smart Contract (12.5 marks)
For this first assignment, you will 1) write a smart contract and deploy to the public Ethereum Testnet (Rinkeby) and 2) list out potential extension in the contract. The motivation for creating this smart contract is to solve a million-dollar question: Where to have lunch?
The required functions for this smart contract are listed below: (10 marks)
1. The contract creator is able to add n choices
2. Only the contract creator is able to add n choices via deployed contract
3. The contract creator is able to select m friends to vote for n
4. Only the contract creator is be able to add m friends via deployed contract
5. Contract creator shall set q quorum.
6. Anyone can list out all the added choices.
7. Each selected friend can only vote once.
8. The contract must stop accepting vote when q is met
9. Anyone can call the getResult() function to get the result of the poll
10. The creator can destroy the smart contract after the poll
How would you extend the functionality of the smart contract? The description should appear as comments in the contract source code. (2 marks)
• List out function definition, variables declaration, and pseudo-code
• Explain why
