Wireshark dissector plugin for the Dash cryptocurrency protocol

A Dash protocol dissector converted from the bitcoin built-in dissector and updated to include Dash specific commands (based on outdated protocol documentation and source code). All messages are now dissected in significant detail.

Current limitations:

  • Governance object (govobj) data field is not dissected
  • The script field of TxOuts is not dissected

To Build (on Linux Mint 17.3)

  • Clone Wireshark from https://github.com/wireshark/wireshark
  • Clone this plugin repository
  • From this repository, copy CMakeListsCustom.txt / the plugins folder and paste into the root of the cloned Wireshark folder
  • Follow the Wireshark build instructions

Note: This was built with Wireshark 2.3. To use with Wireshark 2.2 it is necessary to build using the master-2.2 branch of this repository

Releases

  • Currently the plugin has only been built on Linux Mint 64 bit. A binary can be downloaded from the releases page.
