This is my idea on Tauchain Logo. Simple, elegant yet have a deep meaning.

Currly Bracket, Bracket and a dot are commonly used symbols in making a computer program. Some with an artistic mind would interpret this as follows; left side is the man, right side is the machine, and bringing them together with the yellow circle symbolizes as logic, forms a like a man raising his arms carrying the world. Yellow circle looks like a golden medal which means the person is rewarded fairly for all his efforts. Some might see this as an hour glass that symbolizes time-stamping.

Tauchain makes it possible for man and machine to communicated with each other with the use of logic, as the word "Internet of Language".

I hope you guys would like this. Peace! :-)
