Near Vote

This is my submission for the Near Certified Developer project, a private, trustless voting contract.

Description

This project is motivated by a future world where everyone has a unique NEAR account linked to their government identification, and political votes can be performed using a secure and decentralised manner. There are of course still huge challenges to this, however, if only a single vote contract is known to be the one true source of information, it could serve as a far better solution than anything using a fully centralized pattern.

The contract in this repository is defined by the following criteria:

1. The government (or anyone) can instantiate a new Vote contract with a given set of voting options as strings, and a given timestamp (Unix nanoseconds) at which the vote will end.
2. Once a vote contract has been intialised, the voting options are immutable, and a new contract must be deployed if a new vote is required, this is by design to prevent tampering with voting options or votes that are ongoing, and also to ensure that there can only be one true vote contract ID, all others cannot be trusted.
3. A vote can only be issued once per user. No wallet can vote twice.
4. A user can only see their own votes, not anyone elses. In order to do so, they must actually sign a transaction so we can validate that they are who they say they are.
5. Once the vote has ended, anyone can see the final results of the vote.

Usage

Getting started

(see below for video recordings of each of the following steps)

INSTALL NEAR CLI first like this: npm i -g near-cli INSTALL RUST toolchain Add the wasm target using rustup target add wasm32-unknown-unknown

You will need to have authenticated with the near wallet in order to deploy the contract, see here:

https://docs.near.org/docs/tools/near-cli#near-login

You will also need to set your "ACCOUNT" environment variable.

1. clone this repo to a local folder
2. run ./build.sh to build the wasm file
3. run . ./scripts/1.dev-deploy.sh to deploy to testnet. Remember to set $CONTRACT environment variable.
4. run ./scripts/2.use-contract.sh to interact with the contract.
5. run ./scripts/3.cleanup.sh to delete the contract.
