In order for rich people to keep their jewels and precious metals safe, they hand over them to those they trust and receive receipts for them. This is actually the beginning of bank use. Using a receipt improves the speed and security of your business. The fractional reserve collection is the fourth phase of the currency. Because bankers treasure houses are filled with gold, silver, jewelry goods, they know that their customers are really useless for the goods themselves; they are safer, lighter and more portable The receipt is more convenient.
Banknote is the next logical step in the development of money. It's lighter than coins, easy to carry, and the value of any distribution is even better than leather. It can represent many different tangible assets (over 400,000 empire coins of emperor) and new possibilities lead to new monetization exchanges. Today, bills such as US dollars are telling us. It is made up of money, so it is easy to repeat, it does not have any essential value anyway. Like the leather fund, the dollar is backed by a central government agency and investors trust the value it brings. Because it is guaranteed by the US government. Changes in today's currency currency are easily manipulated only by the government, bad officials, or basic market variables. It is talking about complex languages, and it is becoming increasingly unreliable, it is part of the reason encryption occurs and the language it uses is spoken.
In the section above, I asked to think of our world as computer simulation. The purpose of this thinking experiment is to prove that money must be the product of our natural existence and that the evolution of money traces the prescribed path given by the original essential features. In the simulation exercise, I wanted to set a product currency that was issued from natural attributes and inseparable from it. Because the system is so complex and beyond our understanding, and entropy is so common, the product currency must have all the features, not just some features.
