3. It's mainly a layered process. When bitcoin comes out, it mainly does some payment functions. When Ethereum comes out, there will be the function of smart contract. But payment and smart contract are actually two different things. Ethereum does things together. After doing things together, there will be very troublesome things. For example, when some people play encryption cat on Ethereum, they want to make a payment, but they can't do it. Actually, from a design point of view, this method is not optimized. When MOAC was designing, it made an ecological thinking about the future. At that time, it was judged that the biggest pressure would come from micro payment. However, the micro payment scene will be the trump card of sovereign legal digital currency in the future, and bitcoin will not be able to eat this piece. In the future, it will be legal digital currency. From this point of view, MOOC MOAC adopts the idea of layering, continuing to support the payment function at the bottom, and then supporting the smart contract at the top. Considering that the biggest pressure in the future will be taken over by the sovereign currency, MOOC MOAC does piecemeal processing here. For example, Ethereum processes 15-20 payments per second, and MOOC MOAC only does payment, Now we should be able to do 1000-1200 strokes, very fast and enough. Then, the fragmentation process is carried out here. Maybe many listeners don't know what fragmentation technology is. For example, in Ethereum, there are 10000 nodes. If you take a smart contract, 10000 nodes are working and doing it repeatedly. When you compare the results, you can confirm that they are right, but the efficiency is not high. Fragmentation means that there are actually 10000 nodes, If you divide it into 100 pieces for every 100 pieces on average, it means that every 100 pieces is equivalent to a small blockchain, which can run its own smart contracts. In fact, it can run 100 smart contracts at the same time, so the speed will be accelerated. So the concept of fragmentation is like this.
