Description

As a part of the Make Lisk Desktop blockchain agnostic, we should create a domain for Network. Said domain is responsible for collecting, displaying nodes on the network.

  • No filtering is required.
  • Apply sorting as currently exists.
• Display the geographical distribution of the loaded nodes on a map.
• Display statistical information about the nodes on the network, including:
  • Peer versions distribution pie chart.
  • Peer height distribution pie chart.
