— CatchUp Sync

— Propagable block size limits

  • Changed to organize the node network for each branch.
  • Implemented Health check for closest peers.
  • Refactored the network and peer package.
  • Added node and network test code.

— Created a node test for each role.

— Created a node discovery test.
