CalDescent 94da1a30dc When merging two states, validate that the transaction signature we are using for the "before" layer matches the "previous transaction signature" that is baked into the "after" layer.
This defends against a missing or out-of-order transaction. If this ever fails validation, we may need to rethink the way we are requesting transactions. But in theory this shouldn't happen, given that the "last reference" field of a transaction ensures that out-of-order transactions are invalid already.

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
