Art blockchain to Daozheng

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.

In Internet cases, electronic evidence has become a difficult problem in Internet trials because it is difficult to store evidence, collect evidence and notarize. By using blockchain technology, easyprovision can solve the whole link trustworthiness problems of electronic evidence, such as generation, storage, notarization and evidence proof; After being linked, each judicial node in the security chain is used to ensure the data's trustworthiness and security; In litigation, evidence goes directly to the Internet court to improve the efficiency of rights protection

easy preservation since 2014, we have been deeply engaged in the R & D and application innovation of the underlying technology of blockchain . By expanding the judicial service channels, we have successfully taken the notary office, judicial authentication center, Internet court, Arbitration Commission, right protection center and other authoritative institutions as the important nodes of the preservation chain, so that electronic data can be saved from the aspects of generation, certificate storage, right protection To the final use, the relevant judicial institutions do synchronous supervision and notarization to enhance the credibility of the blockchain certificate data

3. How to operate the isolation witness? In fact, it's not so simple ~
isolation witness is a method of blockchain expansion, which has been successfully implemented on lightcoin and bitcoin
at present, each block in the blockchain not only records the specific information of each transfer transaction, that is, at which time point the account receives or transfers out how many bitcoins, but also contains the digital signature of each transaction, which is used to verify the legitimacy of the transaction. The miner needs to verify each transaction one by one with digital signature when packing the block. After confirming that there is no problem, the transaction will be recorded in the block
however, for ordinary users, they only care about the number of assets in each account, and do not need to verify each transaction one by one. Isolation witness is to take out the digital signature information in the block, so that each block can carry more transactions, so as to achieve the purpose of expansion.

4. I took the examination after I signed up for the study at the Hashimoto business school. They are junior, intermediate and advanced. Different levels of learning have different content and depth. Elementary is the basic knowledge of the introction of popular science, very simple.

5. Hashton business school is good. It focuses on blockchain ecation and training. Through group learning and taking the exam, it has obtained the certificate of blockchain consultant.

7. Blockchain technology can solve a series of problems of art market ownership, authenticity, trust, openness and transparency, transaction and circulation, mainly in the application of anti-counterfeiting traceability and decentralization.

8. Log in to Baopin's personal Center - My Video - and you can see the video certified by blockchain

9. Has anyone used the blockchain right authentication on baopin.com? Does China recognize the video right after authentication?

10. In fact, it's not necessary. It seems that blockchain technology has been approved by the Supreme Court as judicial evidence, so it's not necessary. If you are still worried, you can apply for a work registration certificate. Anyway, it is not expensive.
