2. No way. Blockchain still has a long way to go. In 2018, any company will only stay on the goal or structure. As for practicality, without 20 years, you don't have to think about it. If you can't stay on the real technology, you can't popularize it. Without hardware and the use of the masses, blockchain is just hype. When the issuers finish collecting the wool, there are still followers who want to cry, In fact, I think AI and the Internet of things have made great achievements. The Internet of things began to be used ten years ago. At that time, the Internet of things was further than the blockchain now, and it has not yet been popularized. AI started its research and development 30 years ago, but it has just started to be used now, and the good ones are apple and Microsoft. As for other companies, At best, it's just making enhanced 3D glasses

broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code

there are many channels to learn blockchain

① you can buy some books related to blockchain, learn some knowledge related to blockchain, take notes in your spare time, and consult relevant information

② watch some videos of blockchain on the Internet, the contents of which are easy to understand, with relevant examples, It's also a very good way to learn

to sum up,

all roads lead to Rome. There are many channels to learn blockchain, and the best one is suitable for you
