1. I transfer
bitcoin to you. Do I still have bitcoin in my hand
the fourth feature of
blockchain assets is that they cannot be copied. The transmission of information on the Internet is . I sent a very interesting picture to fire coin Niuniu. The network copied the picture in my hand to Niuniu. It wasn't really taken away from me. I still have this picture in my mobile phone
right on the Internet has always been a big problem. Words, pictures and images are easy to , which brings great trouble to their right owners
the reason why blockchain assets can become assets is that they cannot be copied. It can be delivered through encryption rather than ing. When I send a block chain asset worth 1000 yuan to Niuniu, the 1000 yuan asset will be transferred from my account to Niuniu's account, and I no longer own the 1000 yuan asset. Non replicability is an important factor to ensure that it becomes an asset.
2. It looks very convenient on the mobile phone. In the era of mobile Internet, mobile phone is a necessity for people. Use the time on the bus to learn about the latest developments of some blockchains, and maybe find new business opportunities.
3. Layer 2 is concerned with the protocols on the chain and off the chain. It is mainly responsible for the message passing, intelligent contract programming and application related functions on the chain and off the chain. That is, the auxiliary framework or protocol built on the existing blockchain system (layer1). If we use the analogy of legal structure, layer1 is like the constitution, which is the basis of all laws. The formulation of laws cannot violate the constitution
by layer 2 protocol, the "state generation" of blockchain transactions can be independent of layer 1, so these protocols can also be called "off chain" expansion schemes. One of the main advantages of using the offline expansion scheme is that it can rece the limitations of layer1 and does not need to change the protocol of the blockchain itself. The layer2 expansion scheme achieves high-throughput state generation without sacrificing the security of the blockchain network
extended data
application direction:
1. Payment: for example, in terms of time, traditional cross-border remittance takes 10 minutes or several days, while blockchain cross-border remittance, e to decentralization, can achieve remittance in seconds. In terms of convenience, traditional cross-border remittance needs to wait until the next day after 19:00, while blockchain cross-border remittance only needs one mobile phone to realize all-weather remittance
2. Sharing medical records: the medical data blockchain sharing platform can achieve many application scenarios. Patient history data and other information can be linked, and medical history and image data can be viewed by personnel entering the system. These medical data can also be used for modeling and machine learning
4. Introction: Lianying technology, affiliated to Lianying blockchain Technology (Guangzhou) Co., Ltd., is an innovative technology company dedicated to the field of internet medical imaging. Independent research and development of hospital level PACS system, IPACS image cloud platform, image cloud machine, electronic film and a series of high-quality medical imaging software procts

5. On January 27, 2018, Western media reported that the graally popular cryptocurrency payment, immediate direct payment for the purchase of works and content, and public records of personal reputation data are some of the impacts that blockchain technology will bring to the media instry. This is a prediction made in the latest report
using blockchain technology, we can add digital watermark containing time, author and other information to news works, and set reading rights according to different contents. Soon there will be "famous brands" in the application field of blockchain technology, which will create various blockchain applications that people are interested in. One of the tasks of media practitioners in the future is to "identify the garbage generated around the application of blockchain technology". Therefore, it is necessary for them to understand blockchain Technology
6. How can designers prevent their works from being embezzled by others? The following contents: how can designers prevent their works from being embezzled by others? Copyright registration 1. Paid right registration: registration department: China right protection center registration fee: photography, fine arts, music works, etc., generally 300 yuan for the first piece, and 3 yuan for each piece from the second piece.

In the process of right registration, there are many restrictions and proceres for filling in documents. If there is a problem in one link, it is likely to lead to the failure of right application. Therefore, it is difficult for non professional partners who are not clear how to carry out right registration in China to apply for right registration. You can try to register the right of the blockchain. All the processes are completed online. The operation is simple, and the application is completed in 1-3 minutes. 2. Free right registration: blockchain has the characteristics of permanent preservation and non tampering. More and more people in the world choose blockchain for free right registration. In China, more and more people choose the blockchain right registration service. No matter digital works such as photos, graphics, templates, audio or video, they can be registered free of charge through Renren blockchain right registration. Legal basis: according to the right law of the people's Republic of China, works of Chinese citizens, legal persons or other organizations, whether published or not, enjoy right in accordance with this law.

Therefore, it is an effective way to protect your right by publishing your works on the public platform. Blockchain has the characteristics of permanent preservation and non tampering. Through Renren blockchain right registration platform, your right can be effectively protected. Operation process: login Renren chain creative platform official website & rarr; Registered user & rarr; Select the right registration column rarr; Upload the work and register it. 2、 Digital watermarking encryption technology digital watermarking technology is a kind of information hiding technology, which can embed right information, identification information, image and other information into video, audio, image, text and other carrier images in a visible or invisible way. When embedding invisible watermark information, because the embedded watermark information is lower than the minimum granularity detection range that the human visual system can bear, on the one hand, it can be used to prove the source of the work as the evidence of infringement prosecution, on the other hand, it can also be used to detect and analyze the watermark of digital works to achieve the integrity protection of works. However, this can only be achieved by professional companies. At present, there is no standard price for the cost, which varies from high to low.
