CryptoDrink [Work In Progress!]

An instance of CryptoDrink is hosted at https://www.crypto-drink.com !

This is a complete rework of the previous Discord Bot CryptoDrink. CryptoDrink allows anybody to create a local CryptoHack scoreboard with friends. The scoreboards then can be linked to some Discord WebHooks, in order to receive automatic announcements when any user in the scoreboard solves a new challenge. Whereas CryptoDrink was previously a Discord Bot, it will now also be a proxy and a website.

Proxy

CryptoDrink now features a proxy over CryptoHack's api, featuring many additional endpoints.

• /api/category lists all known challenges of a category
• /api/challenge lists all known flaggers of a challenge in a scoreboard
• /api/scoreboard allows the creation of a scoreboard, the registration of users in a scoreboard and the connection of a scoreboard to a Discord webhook
• /api/user lists all known data about a user, as well as his completion progress for each category

The proxy is entirely coded in Java with Maven + Quarkus in the folder src, following the traditional layered architecture. It uses a postgres database named cryptodrink which can be configured in the resources. The backend should be started with maven.

mvn clean package -Dquarkus.package.type=uber-jar
java -jar target/CryptoDrink2-1.0-runner.jar

Webhook

Flag announcement is now managed thanks to webhooks. This is directly implemented in the backend: when the data regarding a user is updated, all new solved challenges are announced through all webhooks of all scoreboards the user belongs to.

Website [Work in Progress]

A frontend features a convenient visualization of scoreboards and user data. The frontend is coded using Vite/React/TypeScript, and should be started with npm.

cd frontend
npm install
npm run build

Create a scoreboard at https://www.crypto-drink.com/scoreboard, then register the CryptoHack users you want to appear on the scoreboard.
