Customization

An example of adding a logarithm operation :

// OP_LOG : Pop top two items, x and y to calculate logarithm of x with base y.
case class OpLog() extends Arithmetic {
　def opCode() = OpCode(0xb0)
　def execute(env : ScriptEnvironment) = binaryIntOperation( env, Math.log(_) / Math.log(_) )
}

Use Cases

Private blockchains require customized script operations based on the Bitcoin script. ScaleChain provides customizable Bitcoin script executor, which is fully compatible with the recent version of Bitcoin script.
