SimBlock Visualizer

Build Status License GitHub version

An online visualizer for SimBlock.

SimBlock is a blockchain network simulator, whose web site is here.

Usage

This visualizer is available from:

You can see the visualization by uploading output.json via the UPLOAD button.

  • output.json, one of the SimBlock's output files, is listing occurred events during a simulation.
  • If no files have been uploaded yet, this visualizer displays the visualization for the default output file as a demonstration.
  • Note: This visualizer supports only the default setting for a list of regions ― BlockChainSimulator.settings.NetworkConfiguration#REGION_LIST.

The correspondence of each visible object is as follows:

  • Circle: a blockchain node.
    • The coordinates (latitude and longitude) are randomly determined around the region of the node.
    • The color is associated with the latest block of the node.
    • Large circle: a miner of the block corresponding to the color.
  • Edge: a propagation from a node to another node at the timestamp.
    • The color is associated with the flowing block.
    • Bold edge: a propagation just received at the timestamp.
