dagviz

Overview

The dagviz command spins up a number of soterd nodes, and has them generate and exchange blocks. It then generates a series snapshots of the dag at a configurable interval and renders them as a group html file as shown below:

Command Line Options

$ dagviz -h
Usage of dagviz:
  -blocktime int
    	Changing Mining Block Time in milliseconds
  -duration int
    	Duration of the Run in seconds (default 20)
  -interval int
    	Interval in milliseconds between each step (default 100)
  -l	Keep logs from soterd nodes
  -nodes int
    	Number of Nodes (default 4)
  -output string
    	Where to save the rendered dag
  -stepping
    	Generating Stepping Results
  -timespan int
    	Changing Mining Time Span in seconds
