Beifeng blockchain video

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.

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. 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
