Human imagination is limitless, and for many years, people have never stopped imagining the virtual world. Whether it’s the virtual network world in ‘The Matrix’, the dream world woven by superpowers in ‘Inception’, or the Oasis space in ‘Ready Player One’, humans have always been eager to enter the virtual world. Thus, the concept of the ‘metaverse’ has swept the globe. However, what is the virtual world? What is it like? How can it be realized? What is its relationship with the real world? These questions have困扰ed everyone. Therefore, the overseas media ZDNet invited NVIDIA’s Chief Technology Officer – Michael Kagan, to try to explain this concept through experts and distinguish between fact and fiction.

　　The virtual world includes the metaverse

　　The metaverse is a virtual world where you can make your fairy tales come true. NVIDIA’s Omniverse is a platform that helps everyone realize this idea.

　　You can create a virtual world in Omniverse, where you can live and collaborate across the global virtual world without geographical or language boundaries, and without any other limitations. You can link this virtual world to the real world, and turn your imagination into reality. All of these belong to the category of the metaverse.online casino cheats and The latest method

　　But what we are doing now is obviously building a virtual world. The biggest difference between the virtual world and the metaverse is that the former does not need to correspond to the real world one by one, while the metaverse needs to correspond to our real world one by one. One of the projects currently being carried out by NVIDIA is to simulate the Earth, which can simulate the real world very well or simulate what will happen in the future? For example, how do we deal with global warming, how do we deal with climate change?

　　In fact, the virtual world, in addition to the metaverse, also includes the simulated Earth mentioned earlier, which is also known as digital twin. You can also simulate large projects before building them. You may have heard that large car manufacturers like BMW are working with us, simulating large projects before building them. Once the company builds something, you have the digital twin of this project, whether it is a data center, a manufacturing plant, or a smart city. You can interact with the digital twin and train your robots to become better robots in the real world in the virtual world.

　　The virtual world cannot do without cloud computing and data centers

　　To build a digital twin in the virtual world, an AI model is needed to help it make decisions and respond to what is happening, and all of this cannot be separated from cloud computing and data centers. It can be said that the data center is a hidden line in the virtual world.

　　Michael Kagan pointed out that the construction of the virtual world requires a huge infrastructure to transform and develop this technology, including higher processing power, 3D images, virtual reality technology, internet connection, and other functions. To achieve these, it is unrealistic to rely on ordinary computer devices to run the massive code of the metaverse, and cloud computing is a good solution.

　　For example, the program that needs to be calculated to simulate the Earth needs to be uploaded to the cloud, then processed by powerful data processing, and finally transmitted back to the client. More powerful data centers mean faster processing capabilities, which will greatly improve the smoothness and latency of simulating the Earth.

　　To connect to the virtual world, you need to input parameters, which are much more complex than the instructions generated by keyboard input. Sensor devices collect the input parameters of users, upload them to the cloud, and then convert them into parameters that the digital twin can understand, so that people in the virtual world can move or issue commands.

　　After the instruction transmission is completed, it is time to move on to the digital twin modeling part. All objects and buildings in the virtual world are virtualized. NVIDIA once inserted a few seconds of ‘fake’ Huang Renxun and his background in its online GTC conference, which required more than thirty staff members to use RTX ray tracing technology to scan Huang Renxun and take thousands of photos of Huang Renxun and the kitchen from different angles. ‘Kitchen’ was modeled in the virtual collaboration platform Omniverse developed by NVIDIA, and finally combined with artificial intelligence to achieve a realistic effect. These require more powerful cloud computing technology and many powerful data centers to support strong simulation capabilities.

　　Cryptocurrency is not a necessity for the virtual world.

　　Cryptocurrency is a medium of exchange that uses cryptographic principles to ensure transaction security and control the creation of transaction units. It is a type of lottery and How to find it (or Online casino and How to find it). It is based on a set of equations open-source code processed by a group of computers around the world, produced through a large amount of computation by computer graphics cards and CPUs, and secured by cryptographic design to ensure the safety of all links in the circulation of currency. The cryptographic design makes it possible for cryptocurrency to be transferred or paid only by the true owner.

　　Cryptocurrency has four major characteristics: first, international recognition; cryptocurrency is not constrained by interest rates, exchange rates, transaction fees, or any other fees, so you can transfer money internationally without any problems. In addition, there is no electronic cash system, which means that your account does not belong to anyone else. Using this system, you will have a private key and the corresponding public key that constitutes the cryptocurrency address.

　　Secondly, low transaction fees. Through cryptocurrency transactions, there is usually no transaction fee. Because miners are compensated for the digital calculations they perform in mining Bitcoin and other cryptocurrencies from the cryptocurrency network. However, if a third-party management service is used to maintain one’s cryptocurrency wallet, some external fees may be charged; thirdly, transaction confidentiality. Online transactions using cryptocurrency are the only transaction channel between the two parties. Information is traded through ‘push’, where you can decide what content to send to the recipient, which is a good way to protect yourself from identity theft or account threats.

　　Finally, peer-to-peer transactions. This is one of the main assets of cryptocurrency payments, without involving any intermediaries or third parties. The technology aims to promote reasonable, immediate, and secure settlements without the need for anyone to participate, including banks or any other financial systemslottery help and The latest strategy. In addition, global networks use blockchain technology to manage databases recording transactions, which means that Bitcoin is not operated by any central institution, but by its network.

　　Although Michael Cagan did not deny the important position of cryptocurrency in the virtual world, he believes that the current task of the virtual world is to do a good job of infrastructure construction. Even without cryptocurrency, the virtual world will steadily advance. However, the virtual world with cryptocurrency has not become better either.
