All I can say is that good for them for such landmark achievement. Reading through the article makes me realise that these people are not looking to sell their invention rather they are about attacking the already establish infrastructure that has been tested and found to be worthwhile but I am actually not bother because its not enough to build a project but convincing people to use such project and for them to abandon the one they have come to know all their life.
They are not really attacking the system,they're just making a better version of the current system.They understood the flaws and hence worked upon it.The technology is of course patented which is bad because open-source makes it available for anyone to contribute to it.
A lot of project, nice ones have been done with some coming with the slogan "the first breakthrough" "the best you are to see" "the new bitcoin" but at the end, its about the faith people have in bitcoin and the blockchain and not about how ingenious the technology is about.
Totally understand that but I'm only embracing the new tech here.Bitcoin's success is not only the tech behind it but mass adaption.
