Shuai Chu, the founder of quantum chain, said: at present, the evolution of the whole blockchain technology is still at an early stage, just like the Internet era 20 years ago. At that time, we could not imagine that there would be applications like Uber on the Internet. The development of technology would give you more diversity. The possibility is the future

According to the technical characteristics of blockchain, Zeng Ming, Dean of Hupan University, gave several possible answers:

1. The most important advantage of blockchain is transparent, unchangeable and distributed ledger. Some areas have never been covered by the Internet, such as acceptance bills

2. Another big advantage of blockchain is that from the perspective of smart contract, it is possible to form more efficient network collaboration at the point-to-point level. Like crowdfunding

3. In the field of innovation, blockchain will definitely be closely combined with the development of Internet of things, artificial intelligence and other fields, including cloud computing, edge computing and so on

3. According to your description, how to turn on the LED light, you need to connect it. You look at the output of the controller, there are instructions. Is the middle word always bright. The ambient light cycle. You connect all the positive wires of the middle word to the positive pole of the controller, and the negative pole to the controller direct light. Then you connect the positive poles of the surrounding lights to the common positive pole. The negative pole of each color lamp is respectively connected to the cycle output terminal of the controller. That's it.
