We need, and have not designed, a good distributed reputation system, 
resting on Zooko's triangle and a large global hash tree that provides 
an unfalsifiable past history of the past conduct of key holders.

Such a global hash tree requires, like bitcoin, a solution to the 
Byzantine Generals Problem - a known hard problem that is nonetheless 
soluble.

A distributed reputation system can also provide things like debt based 
money that provides an incentive for seeding - for providing storage of 
interesting content as well as an incentive for upload bandwidth of 
interesting content.  Bittorrent provides an upload bandwidth incentive, 
but no storage incentive.
