In the era of mobile Internet, no matter text, picture or video, people can broadcast live on the Internet. Webcast not only compresses time and space, but also enables users to watch sports events, major events and news in real time. Besides, it can also add functions such as text chat and gift giving, which can transform the traditional one-way transmission into two-way interaction and increase the enjoyment of live streaming. However, the lack of presence and single interaction are the biggest shortcomings of traditional 2D live broadcasting, which is solved by the emergence of VR live broadcasting technology of DCM flow mining machine, which promotes users' live broadcasting experience to a new level.

The VR live broadcast of DCM flow mining machine has been widely used in sports events, hot news, concerts, press conferences and other scenes. The live broadcast through VR technology can bring users an unparalleled sense of immersion, making users feel like they are on the spot. V R live streaming requires more network bandwidth than flat 2D video. However, limited by the cost of network bandwidth, many VR live streaming platforms will compress the transmission bit rate to reduce the cost, which will lead to unclear and dizzy experience and greatly reduce the experience of users. In addition, the single form of VR live broadcasting experience can only be used for passive viewing, and the lack of interaction makes the experience boring. However, with the rapid development of cloud computing, 5G and gigabit broadband network, DCM traffic mining machine will further enhance and improve VR live broadcasting technology and integrate social elements, which will greatly improve VR live broadcasting experience and provide feasibility for the commercialization of VR live broadcasting.
   
With the help of cloud storage +5G and gigabit broadband network on the IPFS chain, DCM flow miner enables 5G+VR live application scenes. Integrate a large number of social elements, greatly improve the VR live broadcasting experience, and provide feasibility for the commercial implementation of VR live broadcasting. At the same time, along with cloud computing, 5 g and the rapid development of gigabit broadband network, solved the VR live before the high cost of traffic, VR live not clear, poor experience, interactive form a single, let users from passive into active participation, more into the scene, break the barriers of space and distance, realize the decentralized YunQuanJing live.
In general, the V R live broadcast of DCM flow miner adopts the traditional live broadcast CDN technology. The typical structure of CDN includes central node, regional node and edge node, among which the edge node needs to be deployed close to users. The main workflow of CDN includes:
· The V R live broadcast content of DCM flow miner is injected to the central node after basic processing such as rotation coding and encapsulation. The central node distributes the injected content level by level to regional nodes and edge nodes.
· The terminal sends a video service request to the CDN, which schedules and returns the address of the edge node providing the video to the terminal.
· The terminal requests video service from the corresponding edge node. If the edge node has relevant video content, it will directly push the video stream to the terminal; If there is no relevant content, the edge node goes back to the parent node for the content.
Human pursuit of beauty has always been never-ending, the lack of immediacy, interaction of oneness is one of the largest, traditional planar 2 d live and Virtual Reality (VR: Virtual Reality) of DCM broadcast technology have solved this problem, for the user to bring unprecedented immersive, prompting live user experience to a new level.
 
5G+ blockchain of DCM flow miner
In the specific application scenario of DCM flow miner, 5G technology and blockchain technology have their own advantages and disadvantages. 5 g technology has the advantage of high data transmission rate, wide network coverage, low communication time delay, and allows a huge number of equipment in its vision is to realize interconnection, all build digitized system of social economy, but as an extension of the technology of 4 g, 5 g technology still failed to completely break the 4 g technology bottleneck encountered, such as privacy, information security, virtual protection of intellectual property rights, lack of trust of virtual trade, etc. Block chain technology as one of the best current topic of "fire", aims to break the current trust endorsement deals rely on central organization mode, the means of cryptography decentralization and information privacy, trade history tamper-proof, traceability, such as the provision of technical support, its shortcomings as mentioned above includes high latency, higher transaction rate is slow, infrastructure requirements. As a communication infrastructure, 5G technology will promote the implementation of blockchain application projects in the future. The two can realize complementary advantages and achieve the effect of 1+1 > 2.
As a cutting-edge communication technology, 5G can be regarded as the infrastructure of the communication system. The blockchain technology is essentially a distributed system layout scheme and an application direction of communication systems. First of all, after the landing of 5G in the future, the network communication speed between the DCM flow mining machine's hardware end to end will be greatly improved. While maintaining the degree of network de-centralization, faster transaction processing speed can be achieved, such as accelerating the speed of issuing instructions and uploading information data by digital currency wallet on mobile phone. Secondly, 5G technology is designed to serve the needs of large-scale Internet of things. The combined application of blockchain and Internet of Things technology makes the cost of large-scale Internet of Things to be "Shared", and the application of blockchain in supply chain and other fields can be implemented rapidly. 5G technology and blockchain technology are in a complementary relationship. 5G technology provides support for the realization of an efficient digital economy, while the blockchain technology of DCM flow miner provides security and trust guarantee for the digital economy.
