I am trying to understand how a distributed network can ever hope to compete with centralized processing speeds of major banks that typically clear 25k transactions per second.

I get the appeal of a decentralized currency and want to back an alt currency that could be deployed in confidence to solve low latency, high transaction problems like gaming or offshore wires like the Western Union Business.

Electroneum wants this markets and I like this coin, but how are they going to solve the latency problems.

My question is really, is a distributed block chain a feasable soltution?
Do any altcoins have the capability of processing that many transactions?
