This avoids duplicate entries from the same host/ip with differing ports. This can occur due to some requests using ephemeral port numbers. Ideally we would filter these out altogether, but this at least acts as a safety net to prevent a very cluttered db and associated "broadcast storm". The main tradeoff here is that multiple nodes on the same IP address will be recorded as a single entry. This doesn't seem like it will be a major limitation, because one of them will remain available.
Qortal Data Node
Important
This code is unfinished, and we haven't had the official genesis block for the data chain yet. Therefore it is only possible to use this code if you first create your own test chain. I would highly recommend waiting until the code is in a more complete state before trying to run this.
Build / run
- Requires Java 11. OpenJDK 11 recommended over Java SE.
- Install Maven
- Use Maven to fetch dependencies and build:
mvn clean package - Built JAR should be something like
target/qortal-1.0.jar - Create basic settings.json file:
echo '{}' > settings.json - Run JAR in same working directory as settings.json:
java -jar target/qortal-1.0.jar - Wrap in shell script, add JVM flags, redirection, backgrounding, etc. as necessary.
- Or use supplied example shell script: start.sh
