Metaverse Weekly: The Challenge of Interoperability

Interoperability will be key to a future metaverse.

One of the key challenges to a fully functioning metaverse is that of interoperability. Within platforms such as Decentraland or The Sandbox, there is coherence between that of the virtual worlds, users, and external blockchain networks. This is internal interoperability.

However, the problem here is that external interoperability between world-hosting applications is less clear. For off-chain platforms and applications, this bridge is even less visible. There have slowly been partnerships and integrations between off and on-chain applications, such as Minecraft joining forces with blockchain applications.

This is only the first step towards true metaversal interoperability. There are some key barriers to achieving interoperability for the metaverse.

They are:

  • Technology – The precise applications and computer programming solutions necessary to unite on & off-chain platforms within a single, open metaverse. Exactly what computer engineering breakthroughs are needed.
  • Economics – Aligning the appropriate economic functions & incentives that attracts users to move across worlds through the metaverse rather than staying within base applications or platforms. 
  • Persistent Connectivity – Ensuring the metaverse is always open & accessible is vital to achieving a growing user base. The metaverse must have uptime like the internet today while remaining decentralized and open so that anyone in the world can participate.

Blockers in Technology & Infrastructure

There are a number of areas, including both hardware and software, that must-see technological improvements or adoption of existing technologies that have not yet experienced widespread use in the market.

Some examples of components needing interoperability are:

  • Avatars / User Wallets
  • Application Programming Interfaces (APIs) & Hardware Components
  • Storage & Database Solutions
  • Assets (currencies, securities, etc.)

Avatars / User Wallets

In a full metaverse, it would be extremely inefficient and troublesome if users had to create a new wallet or avatar for all the different worlds that they may want to participate in. For example, say a user wanted to buy land in Decentraland while maintaining a profile through an external P2E gaming title. Having two different identities could get confusing to maintain. Now consider having to create a new avatar for every single platform in a full metaverse.

Comparatively, the internet (web2) has suffered in part from this challenge. Users engaged on multiple websites and platforms must store login information for dozens of different accounts. Solutions like Facebook, Google, and email sign-ins have assisted users with this issue, but it isn’t perfect.

Cryptocurrencies have also had this issue in the past. Each user would have to store the information for various wallets compatible with each cryptocurrency each user wants to invest in. Now, solutions like Metamask have offered cryptocurrency users the ability to store many different cryptocurrencies in a single wallet – regardless of the number of different blockchain networks that user is engaged in.

The metaverse faces this issue as well, albeit it is more closely aligned with the adoption of cryptocurrency wallet technologies. A user should be able to create a single avatar linked to their wallet of choice to transverse the metaverse space.

APIs, CPUs, & Hardware

As platforms are developed, there are many different APIs powering different metaverse projects. External APIs can be utilized by different projects for different purposes and open source projects can work, learn, & build collaboratively.

Additionally, advances in computing power and ability are necessary to run a connected metaverse space. Advances in quantum computing have made headway in this area, helping to push forward major advances in rendering speeds & processing power. Modern computers simply are not sufficient enough to carry the load of such a demanding space.

Storage & Database Solutions

One of the most important parts of the metaverse is that of data storage. Centralized databases simply will not be appropriate for the metaverse as the freedom of data is extremely vital. Therefore, decentralized data storage solutions will be a major functioning part of a true metaverse.

Solutions to global file sharing and database storage have emerged in recent years. For instance, blockchain-powered storage solutions such as Filecoin or Storj have assisted the space in utilizing decentralized storage where users can exchange surplus storage space for a fee.

Interoperable Assets

This aspect of the metaverse is arguably the furthest along. Assets in this circumstance would refer to cryptocurrencies, collectables, non-fungible tokens (NFTs), and other currencies or securities that would have value within a digital space like the metaverse. This is integral to the purchasing and trading of digital LAND within the metaverse.

NFTs and cryptocurrencies have been at the heart of decentralized virtual world hosts so far for on-chain applications. Additionally, the creation of bridges between on and off-chain assets like Germany’s breakthroughs assists in the future interoperability between blockchain applications & external platforms.

Aligning Economic Incentives

While technological interoperability is arguably the most difficult aspect of metaversal interoperability, proper meta-economics also requires a high degree of interoperability. This plays directly into the ability for digital assets to have bridging potential to external applications.

Tech giants such as Meta (Facebook) building out their own metaverse spaces could split on and off-chain users if there is no way for digital assets to be converted into usable assets for Meta. In a way, this is the barrier between blockchain and traditional financial markets today in terms of the cryptocurrency market. It is worth noting that many big tech companies are adopting principles of Web3 technology, but it is only a start.

Additionally, users are generally considered to be rational thinking and opportunistic. This is extractable from game theory. If there is no incentive to participate in external applications, then users will never migrate out of their home apps. This obviously creates competition within the market to fight for capital and user growth, but it is not all necessarily on projects.

Should users ever choose to transverse the metaverse space between projects, it must be:

  • Efficient to move between applications
  • Affordable to the user in terms of fees
  • Have an opportunity cost that incentives dynamic movement across the metaverse

These three points are also true for attracting actual users to the metaverse in the first place, including that of individuals and organizations. Within capitalist economies, entities are profit-seeking. If there is a reasonable expectation that those entities can join & transverse the metaverse in a monetarily productive way, they will.

Accessibility & Durability of the Metaverse

For the metaverse to work and interoperability to remain a feature, the metaverse’s base functionality must always remain accessible to all users and have unlimited uptime. These same qualities can be applied to the modern day internet.

If the internet itself was not accessible or had catastrophic issues with uptime, the digital space would never work. Neither institutions nor individuals would invest time, money, or resources into something that is unreliable or inaccessible. Problems with accessibility can and do plague the internet geographically.

Some areas of the world – like parts of the United States – simply do not have the infrastructure required to have reliable internet access. This is something that the metaverse will also face, just at an elevated level due to the higher demand it requires in terms of infrastructure capabilities.

Additionally, centralized ISPs provide a barrier to entry for users wishing to access the metaverse in authoritative parts of the world. Corporations, governments, and other centralized entities can’t have immediate control over access or durability of the metaverse for it to remain truly open to all. The fight for net neutrality was indicative of this for the internet despite it being repealed in 2018 and never re-implemented.

Interoperability would ensure that even when individual applications or protocols go down, users within the metaverse will still have access to all other applications, guaranteeing that the space will always have some form of functionality.

Final Analysis

A fully interoperable metaverse is still many years away. Advancements are needed in many different aspects of the metaverse, including:

  • Technology & Infrastructure
  • Economics
  • Accessibility

The largest barrier to the metaverse resides in the ability of the world to innovate and upgrade infrastructure, something that will be costly moving forward, especially for end-users. The crypto economy has helped to provide missing economic incentives, helping to fuel such a mass interest from external organizations surrounding the metaverse.

In a perfect world, the metaverse will end up being an open-source, highly durable base layer of what would essentially be the three-dimensional internet. Websites and applications would come to life in a highly connected, interoperable space. 

According to Citi Financial, the metaverse economy may be worth up to $13 trillion by 2030. So, while a true metaverse is potentially years to decades away, there is a sizable amount of investment and interest happening right now to add to its progress.
