Bitcoin was the worlds first currency over blockchain. Steemit is the worlds first social media platform over blockchain. Bitshares is becoming the most prominent trade and exchange platform over blockchain. We already have basic email over just about all blockchains.
It is only a matter of time before we have imagine over blockchain, and then from there, voice over blockchain(VOBC), and video over blochchain (VIDOBC).
I cant wait for vidobc, because youtubes needs some competition.
Can you image the day we have video over blockchain and steemit being the comments platform for social interaction??
Youtube wouldn't stand and chance!!!!
