The blockchain-based technology, the flower of the Fourth Industrial Revolution, is creating tremendous issues in the world with cryptocurrency. Other than Bitcoin, there are over 1,000 altcoins that are created as alternatives to Bitcoin. Such blockchain-based cryptocurrencies are considered as a target of speculation and a bubble in the world. It is because these coins cannot be used. In other words, since there are no places to use, coins based on blockchain technology expose usability problems. It is because the crypto economic system and the existing economic system are separated. This is also due to the longer payment time, depending on the current transmission speed. In order to supplement these problems and evolve into usable currencies, various altcoins are being made as technology base.Almost all experts believe that cryptocurrencies will become commercialized in the next decade or so. However, STARCOIN was created to speed that time. Several requirements must be met in order for the public to use cryptocurrency. First, the volatility should be low. / Second, it must be a safe asset management. / Third, rules and regulations are required for use. / Fourth, the purpose of use should be clear. / Fifth, everyone should be able to use. STARCOIN has been created to solve the above five problems.The most important thing for a blockchain to be a system of technical superiority in the payment system is that it should be suitable for M2M (machine-to-machine) micropayment, which will become common in the IoT (Internet of Things) era. In particular, despite the fact that the distance between countries has narrowed considerably, as the information of each country is updated in real time due to the development of transportation and the Internet, there are too many inconveniences and issues to use global payment methods so far.
