Video of blockchain

1. 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

3. 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

4. Blockchain, as the name suggests, is like being composed of numerous blocks. In the case of bitcoin blockchain, more than 400000 blocks have been generated. The whole blockchain is like a shared distributed ledger, which is jointly maintained by multiple computing nodes participating in bitcoin transactions, Each node also has a complete account backup (complete blockchain data), and each block, like a page in the account, records several different transaction information, which cannot be tampered with by one of the nodes Transferred from Hexun)
blockchain is just a technological innovation, which can be used by anyone. The potential of blockchain is very huge, which can subvert all walks of life. European crowdfunding uses blockchain technology to combine digital currency with real assets. As an asset voucher, digital currency can be freely traded in the market.

5. 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.
