Settings

Network settings

Network-wide settings are compiled with the source code and can be managed with application.conf file via typesafe config library.

app {
  # Release name. Will be used by peers to identify the network
  release = "Lagonaki"

}
scorex {
  # Full path to the main hash function. It should implement CryptographicHash interface. You can find a lot of hash functions in scrypto library (https://github.com/ScorexProject/scrypto).
  fastHash = "scorex.crypto.hash.Blake256"

  # Full path to slow and most secure hash function. It should implement CryptographicHash interface. You can find a lot of hash functions in scrypto library (https://github.com/ScorexProject/scrypto).
  secureHash = "scorex.crypto.hash.ScorexHashChain"
}

Node settings

To run your Scorex node you should create json file with application settings. Most of settings have default values so you may provide just few settings to customize your app.
