Ripple's consensus algorithm.

[James A. Donald]

Bitcoin's consensus algorithm is weight of computing power, which is OK 
as long as weight of computing power aligns with interest in bitcoin 
being a useful currency.

Weight of stake would be better, but so far I am unaware of any 
satisfactory proposals for weight of stake.

Ripples consensus algorithm is weight of club members, and the process 
for getting into the club is opaque, as are the interests and incentives 
of the existing club members.

I would suppose one gets into the club if no existing member blackballs 
you, which would be fine if there is already sufficient diversity of 
interests within the club.

It is not obvious to me how well the ripple consensus algorithm would 
work in the event of substantial conflicts between club members, or bad 
behavior by club members, or bad things happening to the network.

Has it been analyzed for performance in the event of bad behavior by 
some club members?
