This is very interesting to know that people from around the world working on bitcoin coding and contribute for the same on GitHub. If there had been team work competition then these guys would have been the winners. Its highly collaborative work being the public domain and imagine so much goes into it coding from different users who has different ways of working and contributing.

How do they do it really? Like someone jumps in over problem and state their solution and all other agree if it works properly?


So issues are published and then coders contribute to this?
How all this added up in the blockchain. There has got be someone with highest hierarchy to embed the updates right?
