I am not sure what to say for you not understanding (wish I could help you), Google or BING & learn like everyone else does. Telling people to buy when you don't understand, really not recommended & or a bad idea. I have watched these applications for a long time, still don't understand fully myself & am not able to resolve anything alone (PoS can only be resolved by multiple users staking online). Other than the fact that these applications are as stated "experimental", bitcoin has advanced in many other simple formats (still not understandable by most) & really user simplified 3rd party layers. There are over 5000+ altcoins now, but most have random access names
