The entanglement of blockchain and AI in the metaverse Part1

In the metaverse world, a virtual world beyond reality, artificial intelligence AI and blockchain technology are constantly combined and intertwined. Today, I'm here to explain the existence of Mr. Ou and Miss A in the Metaverse, like water helping fish and fish helping water.

With the development of the Internet, the epidemic has changed human life, and many things have been changed to online. The promotion of new technologies is unstoppable like a torrent, and the virtual world has become a reality. In turn, the industry represented by the Metaverse has sprung up like mushrooms after a rain.

"Metaverse" is "meta" meaning "virtual, transcendent" and "verse" is the reverse formation of "universe". The Accelerated Research Foundation (ASF), a non-profit technology research organization, divides the metaverse into the following four categories:

Experience the virtual world of the perfect virtual story

A mirror world that reflects the current real world

A mix of information and life logs in the augmented reality world showing the real world (facebook)

It can retrieve and store daily information of people and things [1]].

As offline and online activities are intertwined, generating all kinds of large amounts of data, the importance of generating value, reliability and security is increasing.

Who will improve the reliability of the data? In real life, we have an official organization or a third-party fair and impartial organization for everyone to agree with; then in the Metaverse, it is based on everyone's consensus to jointly agree on the value (Bitcoin originally It is to reward the contribution of miners, everyone has a consensus, thank you for the reward you have recorded and recorded).

The Metaverse needs blockchain technology to ensure the reliability of data, and uses artificial intelligence to ensure the diversity and rich content of the Metaverse.

Virtual world and desire to create

Humans have been making history, piecing together skills and exhibiting culture. Humans are spiritual creatures, and only human beings can constitute a culture. According to SeaCircle theory, creativity is explained as an element of open mind and spirit [3]. In terms of SeaCircle concept, Metaverse can be understood as a space that allows people to be more immersed in creative activities by solving some space and resource constraints.

The connection between the virtual world and the real world

The virtual world and the real world are integrated and developed, and what ordinary people can feel most is Facebook.

An intelligent revolution is taking place as people and things become highly connected online and offline. There is a convergence phenomenon in which production and consumption occur at the same time. The offline world composed of physical materials is dominated by Pareto's law. Due to limited resources, the results under economies of scale will focus on the development of 20% of the core industries. In the world of online information, however, the long tail effect will be shared and found by 80% of marginalized (non-mainstream) consumers to find the opportunity to truly love the product.

The first, second, and third industrial revolutions solved the problem of material production and supply, but this stage of the [fourth industrial revolution] is the increase of products for human "personal desire" and "spiritual satisfaction". A new fusion of the online world is being created in the world of online information.

The Combination of Reality and Virtuality in the Metaverse

Political, economic, social and cultural interactions occur in the metaverse, mimicking the real world. Figure 1 shows the process of the interaction and fusion of the real world and the metaverse [4], where the metaverse can satisfy another world that the real world cannot. (Example: There is a company in Korea that helps a mother who is in the throes of losing her daughter to spend the day when her daughter comes back and say goodbye....)

Roblox enables game developers to create games on the Roblox virtual platform without commuting to the office [6]. In exchange for labor for tokens, the tokens obtained in the game can be brought to the real world for cashing.

In the Metaverse, users can freely trade goods and services according to the currencies and transaction methods provided by the platform. The Sandbox's virtual asset SAND and Digital Land's virtual asset MANA are both listed on exchanges and actively traded [7, 8]. This means that tokens in the virtual world can substitute for currencies in the real world. Co-creation of games in the space of the virtual world is to exchange space in the space of the real world, and the exchange of assets occurs.

Data trust in the virtual world

When part of the virtual world plays a role in leading the real world, digital advertisements on social platforms are the most interesting.

The issue of whether real things become reliable and influential data in virtual worlds, where trust technology becomes a crucial issue. And blockchain is seen as one of these trust technologies.

Blockchain can be said to be a technology that gives trust in transactions between individuals. A blockchain consists of blocks containing data and a chain connecting them. It is a blockchain to create and connect blocks, using a consensus algorithm in the process. Any node participating in the network can create blocks, but not all generated blocks are connected, only one block is identified and connected. Since only one of the many blocks is connected to the previous block, while the rest are discarded, it is essential to reach a consensus among participating nodes to choose a block. As a method of reaching consensus, consensus algorithms such as Proof of Work (PoW) and Proof of Stake (PoS) are used. If all nodes believe it is the only block, the node that created the block will receive cryptocurrency as a reward. This action is called mining, and the blockchain that is only connected to the blocks produced by mining is called the canonical chain.

While Blockchain 3.0 anticipates that AI will be applied to more expanded fields, more diverse applications of Blockchain and AI are expected to appear in the Metaverse environment.

Metaverse based on blockchain

Ethereum code, Ethereum is a platform network, various decentralized applications (DApps) based on the Ethereum blockchain. Just as the basic framework and details of an Internet protocol are documented as RFCs, Ethereum Requests for Comments (ERCs) document the details of Ethereum. In a DApp, the basic protocol for issuing tokens is represented as an ERC-digital. ERC-number is the protocol to follow when issuing tokens from DApps using the Ethereum network.

Among them, ERC-20 is no stranger to trading virtual currency, which is a protocol related to fungible tokens. ERC-20 tokens have the same value and functions and can be exchanged with each other. The Ethereum project is issuing ERC-20 based tokens that can be used for investments and various businesses.

The NFT (non-fungible token) that is often heard recently is an ERC-721-based protocol. NFTs guarantee uniqueness by permanently storing the encrypted transaction history on the blockchain. Each token has a unique identifying value that verifies ownership of digital assets and assigns value to transactions. Mainly used to commemorate special moments or collect digital assets, NFTs are recently creating new digital content businesses by combining with the Metaverse.

A Metaverse Built on Ethereum

The metaverse is a three-dimensional virtual space where social and economic activity is as ubiquitous as the real world. NFTs play the role of value medium and proof of private property in the metaverse. An example of an NFT application is the blockchain cat CryptoKitties. This is a blockchain based cat breeding game. In CryptoKitties, game users have only one cat in the world. Cat digital assets are rare because, unlike existing virtual assets, they contain a separate unique identifying value.

What is the biggest difference from previous games (electronic pets, characters)?

In general online games, when the service is terminated, there is a problem that the characters developed in the game can no longer be owned. However, digital assets with NFT technology can be distributed and stored by individual participants connected to the network to prove ownership.

Decentraland decentralization realizes the concept of real estate in the Metaverse by combining virtual reality and blockchain technology [12]. It is possible to purchase land (a type of virtual real estate) using the ERC-20 token MANA. Users can freely place buildings on land purchased from Decentraland, earn income by putting up billboards on buildings, or host exhibitions by collecting rare digital content. Land titles and other collectibles are ERC-721 non-fungible tokens. These unique assets are made through Ethereum smart contracts and allow owners to prove ownership on the blockchain ledger. The cryptocurrency MANA can be purchased on exchanges and can also be used to purchase digital goods and services around the world. Xi Xiaoxiao, I think Nintendo's Animal Crossing should have a project during the crazy period...

Of course, most of the virtual worlds started with games, then we should mention Enjin Coin, a cryptocurrency project created by treasure trading. Simply put, it is a blockchain-based treasure exchange platform. Ethereum-based ERC-20, ERC-721 and ERC-1155 token projects can be stored and managed in mobile cryptocurrency wallets. Enjin Coin guarantees the ownership and monetary value of all game items used in the game . Since it is valuable, of course, in real life, it is possible to exchange chicken legs XD.
