Krystal Bull is a full featured DLC Oracle. This project is built on top of the Bitcoin-S DLC Oracle module.
To get started you will need Java, Scala, and some other nice tools installed, luckily the Scala team has an easy setup process!
Simply follow the instructions in this short blog to get started.
After having these installed you simply need to clone the repo, then run with sbt run.
brew install scala
brew install sbt
