Redefining the three greatest inventions of humanity; the letter, the currency, and the law

We believe that Blockchain technology redefines the three major inventions of mankind for the contemporary society we live in. We aim to contribute to our society through utilizing the company's networks for this technological development.

WOODMAN Co., Ltd. CEO Shinjiro ONO

The three greatest inventions of the mankind;


The progress of the ancient Mesopotamian, Egyptian, Indus, and Chinese civilizations would have ceased without the invention of letters. It goes without saying that because of letters it became possible to accurately communicate what would have been mere oral folklore until then.


In the times of ancient civilization, it is said that a certain volume of barley in a cup functioned similarly to money. The invention of currency led to the invention of the “measure of value,” which increased the number of trades significantly, leading to high food security, and formed a basis for the increase in population.


As letters and money were invented and humanity had made great progress, societies faced varied and new issues—what mankind invented then was the law. Already at around the third century B.C., the notion of the law had been well established, as seen with the famed King Hammurabi, who issued the “Code of Hammurabi," advancing his society as a whole.

Considering the impact of redefining the three greatest inventions—Blockchain is a groundbreaking technology full of potential and prospect.
