Java Chain

Explorational and educational Hobby project.

Projects Goal

• Explore Blockchain underlying mechanism, problems and ideas
• Having Working and Deployable software
• Create own useful primitives

Build & Run

Gradle

#Build 'fat' jar

./gradlew clean shadowJar

You can start one or several process listening on different ports by providing optional argument

#Process one
java -jar build/libs/org.holbreich.java_chain-1.0.0.jar 5000

#Process two on another port
java -jar build/libs/org.holbreich.java_chain-1.0.0.jar 5001

Docker

Build with Docker or Podman

docker build -t java-chain-app .

With containers the networking part becomes trickier. We need to put containe in one network first

docker network create blockchain-net

Then we can run freshly built containers with interfaces in that network. Run using -it if you like to stay attached to input stream and append "Transactions"

# First interactive
docker run -it --name node1 --network blockchain-net -p 5000:5000 java-chain-app 5000
# Second node on different port.
docker run -it --name node2 --network blockchain-net -p 5001:5000 java-chain-app 5000
