Protocol signatures and ports

Bitcoin and libtorrent protocol signatures have been changed on purpose to make twister network incompatible. This avoids the so called “merge bug”.

The changes are:

  • Bitcoin signature changed from “f9 be b4 d9″ to “f0 da bb d2″.
  • Bitcoin port changed from 8333 to 28333.
  • BitTorrent signature changed from “BitTorrent protocol” to “twister protocollll”.
  • BitTorrent/DHT query changed from “y” to “z”
  • BitTorrent/DHT answer changed from “a” to “x”
  • BitTorrent/DHT port is registration network’s port +1000 = 29333
