The use of SHA-1 in v1 seems like a major problem. [edit] That doesn't imply that BTv2 is the right successor protocol.

  It’s not currently - collisions are very expensive and only in limited contexts. If you wanted to distribute malware via torrents your efforts are better spent elsewhere.

    Attacks only get better with time. Also, this seems quite bad: https://en.wikipedia.org/wiki/Collision_attack#Chosen-prefix_collision_attack https://en.wikipedia.org/wiki/Collision_attack#Chosen-prefix...

      That attack isn't relevant to bittorrent swarms. What you want is a preimage attack on SHA1.
