1. In the process of certification, we often hear the words of mine safety certification and coal safety certification. Sometimes we feel that they are not the same thing, but what we see on the Internet is that they are both the same thing. Why< In fact, both coal safety certification and mine safety certification are abbreviations of coal mine safety certification, which can be written as Ma and Ka certification. This is a national compulsory certification for mineral operations. Only with these certificates can we sell, purchase and use mine procts with safety marks
there is no difference between the two. We can regard them as one thing.
2. Digital cash, also known as "e-cash", is an encrypted serial number of cash signed by the bank. It is a digital currency based on blind signature technology researched and developed by David Chaum. It is suitable for small amount real-time payment on the Internet
e-money is developed on the basis of traditional money, and has a lot in common with traditional money in nature, function and function. For example, the essence of e-money and traditional money is a special commodity which acts as a general equivalent. This special commodity is reflected in a certain social proction relationship. At the same time, they have five functions: value scale, circulation means, payment means, storage means and world currency. They reflect the value of commodities, mediate the exchange of commodities and regulate the circulation of commodities.
3.


the world's first digital currency was invented and issued by David Chaum, known as the father of digital currency. As a mathematician, cryptographer and computer expert, he began to study how to make digital currency in the late 1970s. Digital currency is a kind of currency existing in the form of electronic number, which is an electronic flow of information transmitted on the network through the circuit composed of 0 and 1. Compared with the traditional real currency, i.e. paper money and coins, digital currency has obvious advantages: traditional currency has greater storage risk, expensive transportation costs, and requires a lot of investment in security and anti-counterfeiting. Digital currency is different from e-currency such as credit card and e-check. It has higher level and higher technology content. It can be used without connecting to the bank network and is very convenient for customers. By the end of 1995, as more and more users of the digital currency invented by JOM, it was accepted by a bank called Mark Twain, enabling it to convert to the real deposits in the user's account
subsequently, many people have done a lot of research work in this area, and put forward many solutions. The first digital cash scheme is proposed by Chaum in 1982, which uses blind signature technology to achieve, and can completely protect the privacy of users. In 1995, Stadler et al. Proposed the concept of fair blind signature, which can be used in conditional anonymous payment system. In 1996, Camenisch and Frankel independently proposed the concept of fair off-line e-cash for the first time. The anonymity of users in fair e-cash is incomplete, which can be revoked by a trusted third party, so as to prevent criminal activities by using the complete anonymity of e-cash. In the course of the development of digital cash, many companies have made their own contributions. Some have failed, but they have made great contributions, such as digicash. Some have learned a lesson and have developed into influential companies, such as Mondex, PayPal, etc
