Metaverse is a portmanteau of 'meta' and 'universe'. It is a hypothesized iteration of the Internet, supporting persistent online 3d virtual environments through conventional personal computing, as well as virtual and augmented reality headsets.
Several components of metaverse technologies have already been developed within modern internet-enabled video games. People usually think metaverse is only for the games, and that's because it has been developed in those ways the most, and they are the easiest ways to think out. So if it reminds you of the games like Second Life, Roblox, Minecraft, or Fortnite, it means you already know and experienced the metaverse in your life.
Metaverse development has often focused on bettering virtual reality technologies due to benefits in establishing immersion in virtual environments. So it means metaverse is not only for games but virtual reality.
Some developers have proposed using metaverse technology for improvements in work productivity. Within the education sector, metaverse technologies have been proposed as a way to allow for interactive environments for learning. The metaverse could also host virtual reality home tours in the real estate sector. It could be a time slap simulator if there's something that needs a simulation but which is much faster than in 'real-reality.'
Artificial intelligence (AI) is intelligence demonstrated by machines, as opposed to natural intelligence displayed by animals including humans. Machine learning is the study of computer algorithms that can improve automatically through experience and by the use of data. It is seen as a part of artificial intelligence. Deep learning is part of a broader family of machine learning methods based on artificial neural networks with representation learning. Artificial neural networks were inspired by information processing and distributed communication nodes in biological systems.
AI, which has been developed so far, includes all kinds of technologies such as recognition, classification, guessing, and calculation. Representative modern technologies where AI is used are medical, autonomous driving, SEO, sensors, and analytics.
More sophisticated and more accurate models are expected to be developed in the future. And considering that there are a lot of things that have already been developed so far, it may be in the nearer future than you think.
A blockchain is a growing list of records, called blocks, that are linked together using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.
Blockchains are typically managed by a peer-to-peer network for use as a publicly distributed ledger, where nodes collectively adhere to a protocol to communicate and validate new blocks. Although blockchain records are not unalterable as forks are possible, blockchains may be considered secure by design and exemplify a distributed computing system with high Byzantine fault tolerance.
Blockchains with various types of consensus algorithms have been developed. And blockchain-based cryptocurrencies (Bitcoin, Ethereum, etc.) and blockchain-based distributed apps (aka. Dapps) are examples that are easy to find around you.
Because blockchain has the characteristics of decentralization, distributed power, privacy, integrity, and security, contary to many misconceptions, experts see blockchain as a new technology flow in the 21st century, calling it the 'second Internet'.
NFT makes people expect the fusion of blockchain and metaverse. A non-fungible token (NFT) is a unique and non-interchangeable unit of data stored on a digital ledger (blockchain). NFTs can be associated with easily-reproducible items such as photos, videos, audio, and other types of digital files as unique items (analogous to a certificate of authenticity).
Taking advantage of this point, users can claim ownership of characters or items in the metaverse game. Or they can also use virtual currency as a currency unit for the game. Even if it is not a game, the fact that all digital assets developed or traded on the Metaverse can be NFTs brings a great innovation to the Metaverse.
If AI is used, meta-life can be implemented in metaverse through advertisement analysis and recommendation. Collaboration with ai, that is, obniverse is possible. It can also be used for mirroring when constructing a metaverse environment. It is also used to enhance spatial computing.
It is possible to discover artificial intelligence business models that converge block chains. A typical example is to provide tokens as a reward for collecting learning data. By developing explanatory artificial intelligence, XAI, input data
and output data, and various Data can be safely stored and managed in real time. And through this, users can have higher confidence in the explanation, that is, the basis for the results presented by artificial intelligence.
The future world in which the three technologies are fused is a virtual world, a distributed world, and an intelligent world. It is possible to create an infinite space, a space without an owner, a space resembling the real world but more advanced. Everything in that space will be flawless, creative and unprecedented. The world will be technological and paradoxically primary.
Q&A
Q. Which NFT do you recommend me to invest?
A. Hi, thank you for your question. Actually, I don't really recommend buying NFTs as an investment. Because NFTs are for claiming ownership of items. I think you should approach its concepts as consumption. But if you're going to buy some of them expecting some profit, I guess it's gonna be good to invest in items that will increase the scarcity of themselves. Items that are expected to be more duplicated due to their high availability, have a long history, or have high commercial or social value, will give you more profit due to its scarcity.
Q. Could you give me an example of blockchain technology which we are using in our real lives?
A. Hi, thank you for your question. A blockchain technology that everyone in Korea is using these days is Coov for Vaccination Certification. This -app, being used to authenticate people's visits, stores and transmits the users' personal information encrypted on the blockchain. If you check the shop owner's guest list, you would know that it doesn't reveal any personally identifiable information. This blockchain history, which cannot be artificially tampered with, reflects users' vaccinations in real time, and allows for integrated and flawless management of visited places.
Q. How can the blockchain be non-centralized? I guess it would need its server or database owned by someone.
A. Hi, thank you for your question. It is a very important and deep question. So please excuse me if my answer is too long to you. ;) The computing power required by the blockchain is allocated to the nodes participating in the blockchain. The method of selecting this node is different depending on the type of consensus algorithm. The first-generation blockchain uses a POW consensus algorithm. A node that proves a transaction (mining) provides computing power and receives a reward. Since the existence of a chain using this consensus algorithm depends on the existence of miners, there are not many functions that can be implemented. The second-generation blockchain uses smart contracts (using the standard of erc 20 token). It is a platform-type block chain that implements functions using a block chain based on the POS consensus algorithm. The POS consensus algorithm is a way to get rewards by betting stakes and proving transactions, so users can stake their stakes and participate in important decisions on the chain. Currently, the block chain stores multiple transactions in one block with a capacity of about only 20kb per block. The same ledger is shared by all users, and on some sites, transactions across the chain can be viewed. It means that the capacity of the blockchain is not that large. Although the third-generation blockchain has not yet been developed, it is expected to emerge as an "Internet Protocol file system' that stores digital data itself on the chain beyond ownership. Cloud, image, internet, and video can be stored as blocks (without having a central server). For this, in order to exclude the server, the encoding optimization technology performed in the node and the cloud server effective resource utilization technology that utilizes the cloud in a distributed manner rather than owned by the company are required. In addition, the development of hardware such as graphics card is necessary. In addition, a group of developers announced a plan to reduce the power of pow to less than 1/100 of the existing amount within a few years in order to increase the utilization of the hardware.
