Searching the web I found a video where the narrator had created a visual demo of blockchain technology in order to explain the procedures behind the bitcoins transactions. May be, this has a little to offer to experienced users since they know the whole process; but for newbies like me is very informative and self explanatory.
So I thought that would be a good idea to share it with you

If this not the right place mods are kindly requested to move it everywhere that should be.
Thanks, is a good video, I will share it in the Spanish section because its English is easy to understand since he doesn't speaks too fast.
Also, It is well explained. I remember that I explained that saying that mining is like doing small changes on a eMule file to get a hash with some zeroes.
