Build Collective

By GUELIANE Belkacem & LEE JaeSoo

Welcome Welcome What you're looking at is the emplimentation of an OpenCollective competitor in a decentralized way, on the Ethereum blockchain as a backend. This will have cool side effects, like not be forced to pay for servers, instead, we will destroy every electrical grid on earth as well as keep the GPU manifacturers busy, in search for privacy, decentralization, freedom and hapiness, just like god intended !!!

Installation

# With HTTPS
git clone https://github.com/ghivert/build-collective.git
# Or with SSH
git clone git@github.com:ghivert/build-collective.git

You’ll need to install dependencies. You’ll need Ganache, Node.js and NPM or Yarn. You’ll need to install Metamask as well to communicate with your blockchain.

• Ganache is a local blockchain development, to iterate quickly and avoiding wasting Ether during development.
• Node.js is used to build the frontend and running truffle, which is a utility to deploy contracts.
• NPM or Yarn is a package manager, to install dependencies for your frontend development. Yarn is recommended.
• Metamask is a in-browser utility to interact with decentralized applications.

Some setup

Once everything is installed, launch Ganache. Create a new workspace, give it a name, and accept. You should have a local blockchain running in local. Now you can copy the mnemonic phrase Ganache generated, open Metamask, and when it asks to import a mnemonic, paste the mnemonic. Create the password of your choice and that’s fine. Now you can connect Metamask to the blockchain. To do this, add a network by clicking on main network and personalized RPC. Here, you should be able to add a network.

Once you have done it, you’re connected to the Ganache blockchain!

Run the frontend

Install the dependencies.

# Yarn users
yarn
# NPM users
npm install

Compile the contracts.

# Yarn users
yarn contracts:migrate
# NPM users
npm run contracts:migrate

Create a symlink for your OS if this is not done for you.

# Windows
mklink /D src\build "..\build"

# Unix and macOS
ln -s ../build ./src/build

Run the frontend

# Yarn users
yarn serve
# NPM users
npm run serve

You’re good to go!

Subject

Implement an OpenCollective from scratch in Solidity.

Smart Contract

• Open user account, with a name and a balance.
• Open an entreprise account, with a name, an owner and some members, possibly with a balance.
• Create projects on which we can give money for sponsoring. Each project has a balance, a name and a list of contributors. Each project belongs to a user or an entreprise. The money given to the project can be send to contributors, and contributors only.
• On a project, you should be able to create bounties. Bounties are bugs with a reward: if you spot a bug and you want to have it fix quickly, open a bounty and put some eth on it. When the fix is pushed, the author will get the eth. He’s a bounty hunter.
• Add the ability to put some link to commits from GitHub or GitLab in the projects, to keep a track of what has been done.

Front

• Create a page to open a user account. Remember, each user is identified by its wallet address.
• Create a page to open an entreprise account.
• Create a page to create a project.
• Create a page to get a full recap of everything that happened on a project as a timeline.

Features

After connecting to Metamask and creating you account, you'll be guided to the main page with 2 tabs:

• The Account page
• The Explore page

Account Page

In the Account page, you'll be able to see your personal account, as well as have the ability to recharge your balance

all your transactions will be deducted from this balance

you also have the ability to view and manage your company (add memebers..)

and finally you can create projects, add members as well as start bounties for the bugs that you want fixed you can also see a recap of all the associated projects, owned by others and of which you're a member

Explore Page

On the explore page, you'll find a list with all the other users

once you click on one of them, you'll see their profile, their organisations, and a list of their projects

on these projects you can donate

or if they have declared a bug, you can submit a fix: in this example

• GB declares a bug
• LJ sees the bug on GB's page and submites a fix

• GB then accepts the fix (visible only on his Account since h'es the owner) and the bounty is automatically transfered to LJ
