Welcome to the DAAR project. The idea will be to implement a complete Wikipedia in a decentralized way, on Ethereum. This will have cool side effects, like not be forced to pay for servers.

git clone https://github.com/ghivert/decentralized-wikipedia.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 runningtruffle
, which is a utility to deploy contracts.NPM
orYarn
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.
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!
Install the dependencies.
# Yarn users
yarn
# NPM users
npm install
Compile the contracts.
# Yarn users
yarn contracts:build
# NPM users
npm run contracts:build
Create a symlink for your OS.
# Windows
mklink /D src\build "..\build"
move /Y truffle.js truffle-config.js
# Unix and macOS
ln -s ../build ./src/build
Run the frontend
# Yarn users
yarn start
# NPM users
npm start
You’re good to go!
Implement a Wikipedia from scratch in Solidity.
The program should be able to:
- Read an article by its ID (an uint).
- Someone should be able to submit a new article with ID and content.
- Someone should be able to update an article.
Bonus:
- Keep history of modifications and display it in the app.
- Integrate the DApp with Fortmatic.
