1. Legally, China only has restrictions on the issuance and speculation of currency in the
blockchain, because a large amount of black money in China, such as those of corrupt officials, will be illegally obtained overseas by means of
digital currency. If the blockchain digital currency is opened up and traded casually, it is estimated that China can not control the outflow of black money. Now the law encourages blockchain. In addition to legal currency, China encourages and supports other blockchain technologies.
2. Basically, the principle is the same. Take baopin.com as an example, baopin.com's video blockchain authentication is actually DAPP. First, it takes a screenshot of the video's key frames per minute, then transcodes it into a string of unique numbers, and then uploads and records it into the Ethereum blockchain.
3. Thank you. Let me give you a serious answer
in fact, the circle effect of blockchain is very obvious, so most people are impetuous, some of them are attentive, and there is very little popular science. I recommend a few here
if you want to watch the video, you can recommend Babbitt's "meow understands blockchain", which is very deep. This is the sentiment of the people who want to watch it. I won't say more about other videos. I think the video of fire coin can also see the words of trust, but it's relatively shallow. I watch it as a kindergarten child
if you are not limited to videos, I think there are several popular science articles to recommend: Jiang Zhuoer's popular science in Zhihu, Gu Qianfeng, lightning, and pan Zhibiao are all great gods. Each category is different. You have to think about it yourself if you want to enter the circle
the things in PS blockchain field are sent here, and there are few people watching them
4. Stabbing himself like a fool, he almost cut off his finger himself. That's the master. You know, he wants to be the most popular
5. Once the blockchain video is on the chain, it cannot be changed. If it is invalid after being changed, the video on Baopin can not be deleted once it is on the chain
6. Blockchain is "efficient and inefficient", "decentralized". Blockchain short video is to put the original short video on the blockchain for authentication, proving that it is original.
7. Course content is good, video can be downloaded directly, do not charge free
8. Black horse programmers have a lot of free videos
9. Want to learn the knowledge of this instry is not so simple, need a lot of precipitation, specific how to operate this software, I have not used, you can ask customer service ah. It's not that complicated.
