When all of the proof of concepts started (since the beginning of every idea or invention in time), being a lot easier for an Alternative to the mainstream coinbase/s & many don't understand the knowledge that it's just not feasibly possible to carry the entire worlds secured data on one or even two designs. It's always easier to build when one = only one (first idea or prototype), but even the biggest movements in life require a second or many vehicles (by hand, automobile, trains, planes, & or the future of moving mountains with the least amount of resources) to balance the load of it's entirety. There's not a single concept in the world that hasn't split or spread between many designs in the actuality of building the prototype better with each & every improvement or new addition to the original design. Many good things can be built with what has been shown to many over the years in all of this, but whether we decide to accelerate or slow (open & closed source) it is up to the world & not held back by just a few any longer? People have been talking about a better world since the beginning of time, but it's all a balancing act of how fast or slow we build the world & who is deciding what pace we move @.
