Big technologies together recreated the basic concept of the metaverse and introduced a more mature 3D world, which can enable an immersive digital experience for the people. Metaverse is now building a new age of the internet, encouraging the masses to gear up to gain benefit from the internet’s next iteration.

Metaverse is currently trending with more people becoming aware of its application, yet people still struggle to understand the formation of the metaverse. Therefore, let’s discuss all the technologies powering the metaverse and leading to the creation of futuristic metaverse projects. In addition, we will briefly examine the origin and the evolution of the metaverse.

Origin of the Metaverse

What is metaverse? Answering this question is not challenging for most people nowadays. One can now easily describe metaverse as a highly immersive internet where users can access augmented reality and virtual reality-based persistent environments and access the offered utilities through their unique avatars and other digital technologies.

However, people might seem confused if they are asked to demonstrate the origin of the metaverse. Hence, let’s discuss it first. Although scientists have utilized the underlying 3D and VR concept of metaverse since the early 80s, the exact term “Metaverse” first appeared in Neil Stevenson’s novel- published in 1982. The characters in this novel could visit a virtual world to escape the real world, which dominates them.

Later in the early 90s, a company named Sega introduced VR gaming devices, including the SEGA VR-1 motion circular, designed to create adventurous experiences for the players in arcades. All these inventions are considered the origin of the metaverse, but the metaverse became a common talk among the masses mainly when Facebook announced its rebranding to the Meta.

Evolution in the Metaverse

Evolution in the metaverse is consistent. Let’s look at the changing metaverse trends to understand how technologies have aided metaverse development, allowing it to become better and feature-rich to align with the ever-changing industry requirements.

  • Facebook rebranded its name to Meta and invested millions of dollars in Reality Labs; a specific division focused on building mega Metaverse projects and content associated with it.
  • Microsoft announced its metaverse-based alternative, Microsoft Mesh, allowing the users to explore immersive 3D spaces and connect further on a common digital space where all the functionalities of Microsoft are integrated for the simplest utility.
  • Inspired by the popular crypto-based game- second life, a creative team of developers- Estaban Ordano and Ari Meilich, launched the first decentralized metaverse based on the gaming niche. Moreover, the platform is planning to enable interoperability elements in its mechanism.
  • After years, blockchain is now set to completely transform the centralized concept of metaverse projects, decentralizing the infrastructure of the metaverse. Many innovative metaverse projects continue to land in the metaverse’s digital space, ranging from gaming and e-commerce to real estate.

Why understanding Metaverse technologies is essential?

Businesses are raving about the various advantages of the metaverse. They are ready to invest in building digitally enhanced immersive worlds to stay aligned with the latest industry trends and better showcase their products & services.

Regardless of their industry type, every enterprise should be aware of the various aspects of the metaverse, as it is essential to shallow point metaverse’s driving force in the business ecosystems, what impact it provides on the users, and how it connects our real world with the virtual world.

Also, understanding the technical aspects of the metaverse development is required to look into the different angles of this shared, open and persistent virtual world for further development of innovation-rich and futuristic projects. With a perfectly-curated project, businesses can bring audiences into the Metaverse and engage them to discover more effective growth opportunities.

Businesses also need to keep up with the metaverse landscape to design their project that corresponds to the latest development trends for maximum impact on the users and targeted audiences.

What are the key technologies powering the Metaverse?

People often define metaverse as a combination of virtual reality (VR) and augmented reality (AR) technologies, but metaverse development is beyond these two basic technologies. Projects like Axie Infinity and Decentraland present the best example of utilizing mainstream technologies into converging the real world with the virtual world.

Among the various technologies powering the metaverse, blockchain plays a crucial role. From providing a decentralized infrastructure to metaverse to supporting the development of powerful use cases for its ecosystem, Blockchain technology has the potential to make metaverse projects compatible with Web 3, which is the next phase of the internet. For that reason, we will emphasize blockchain technology more and deeply examine it.

key technologies for metaverse

1. Blockchain

Metaverse can be centralized, such as Facebook and Microsoft’s metaverse. However, blockchain technology and its use cases like NFTs and cryptos aim to replace the centralized concept of metaverse with a powerful and decentralized infrastructure.

Blockchain further plays a vital role in metaverse development because the future of the web, i.e Web 3.0 is all about decentralization. Thus, to sustain a decentralized web, even metaverse projects need to be built as decentralized platforms. Blockchain technology can impart decentralization into metaverse projects. Following are the decentralized elements that blockchain offers for the metaverse:

Storage

The decentralized blockchain database provides far more extended storage capacity than the centralized storage system. By utilizing users’ unused hard disk space worldwide, blockchain avoids users in the metaverse running out of space. Decentralized storage also helps in fixing other shortcomings of the centralized storage system, like third-party involvement and potential unethical activities such as data stealing and file manipulation.

Security

Data on the metaverse is stored in exabytes, raising security concerns among the users regarding safe storage, data transmission, and synchronization. Blockchain addresses these concerns through its decentralized storage capacity and powerful data processing and validation nodes.

Trust

Information on the blockchain, such as user data, ownership details for the virtual content, authorization keys, and transaction details, are stored in an encrypted form. These data are verifiable through decentralized consensus, with no third-party having access to it. Only the nodes can read and verify these data to maintain trust and authenticity.

Complete decentralization

The decentralized ecosystem of metaverse enables thousands of nodes to run independently to allow synchronization. The metaverse can never experience issues like a single point of failure, limited scalability, or delay in process execution.

Smart contracts

Through smart contracts, metaverse can create and implement various rules related to the ecosystem’s operation. These contracts are self-executing, which means the contract between two participants is marked as “Done” if the predetermined condition or rules inside the contract are met.

Interoperability

Blockchain enables interoperability across various metaverse projects, allowing them to interact seamlessly and perform actions like sharing arbitrary data, related information, and resources.

Blockchain use cases supporting the Metaverse
Blockchain can be applied in many ways to develop and operate a metaverse project. Below are some of the top use cases that enterprises should know:

NFTs

Gaming-based metaverse projects represent a major part of the overall metaverse projects existing on its horizon. For such projects, NFTs take up a vital role with their ability to offer immutable digital proof-of-ownership. When integrated into the metaverse, NFTs regulate activities related to the trading of digital assets, representing the users’ unique avatars, building a digital economy through cryptos, etc.

Cryptos

Being the depiction of the real world, the metaverse enables users to perform every activity inside this virtual world that is possible around us. These activities can include meeting people, traveling to different places and engaging in trade activities. A global currency is required to power all such activities, which can be achieved with crypto. Any monetary transaction on a metaverse can be powered by crypto. Users can utilize this money to pay for utilities, both in the virtual and the real world.

Self-identity authentication

Verifying a person’s identity requires any government-issued identity card, social security number, passport, etc. In the metaverse, users’ self- identity authentication works quite similarly. All the data about the users, such as body appearance, activity, age, and other unique characteristics, are safely stored across the distributed ledger where nodes validate these data. It prevents the risk of false activities inside the metaverse. For instance, an Avatar can commit illegal actions by acting as someone else’s avatar.

Technology stack for blockchain development 

Front-end development refers to the development aspect that focuses on visual elements of a decentralized application that users will interact with.

  • JavaScript-based framework; React-native.
  • HTML
  • CSS
  • Websocket
  • Web3js

Backend development- The backend of any blockchain-based solution is mainly the smart contract where the code runs across a decentralized peer-to-peer network to regulate the dApp.

  • Solidity
  • Rust
  • Node.js
  • React Native
  • DocumentDB
  • MongoDB.
  • Auth0
  • Web3js

2. AR and VR technologies

Augmented Reality and Virtual Reality are the access point for the metaverse. Both these technologies are the gigantic engines required to support the creation of the metaverse project that can facilitate immersive experiences and a more engaging three-dimensional digital world for the metaverse.

Virtual reality technology provides users with a connected experience in the metaverse. A shared meeting stands as one of the best examples demonstrating the use of VR technology in enabling connected experiences. With time, VR technology is utilizing other big technologies to evolve its existing application and enhance the ability of Metaverse to provide engaging and immersive 3D experiences.

On the other hand, augmented reality expands the use of virtual reality. Let’s take an example of a brand selling racing cars in their VR showroom inside the metaverse. Through VR, brands can only offer a virtual representation of the cars inside the store available in the metaverse. However, augmented reality allows the buyers to go for a digital test drive and test the car personally before buying.
