The question of interoperability in the Metaverse

Joshua Bates, TMT Associate at Global Counsel writes about the implications of ownership, security and interoperability in the metaverse

Before beginning to explore what the future of the metaverse may be, we must first answer the question of whether we are talking about the Metaverse, or metaverses. Whilst at first glance this may appear to be a grammatical choice, in truth, it speaks to a broader question of whether the Metaverse will become a singular, shared and interoperable space, or a series of isolated, but perhaps more secure, sporadically connected digital environments of metaverses.  

Whilst the first offers unlimited opportunity for collaboration, innovation and competition, it does present questions surrounding security and accountability; if nobody has ownership of the metaverse, who ultimately takes responsibility for safety? Closed-off metaverses offer a partial solution, in that whilst companies will – in principle at least - be more able to oversee and better protect user experiences, competitors could struggle to enter the market and users may feel locked into particular platforms.

When conducting our research and interviewing tech experts, regulators, and officials, we asked them for three keywords that defined the Metaverse. Interoperability was, by a considerable margin, the most used word across the UK, US and EU stakeholders we spoke to, as most felt it was a basic principle of what the metaverse should become. A common theme quickly emerged that many saw a successful metaverse as one where users could hold a consistent digital identity that could be carried in-between virtual worlds.  

Our public polling on the other hand found that the issue of interoperability was not a core concern when compared with online abuse or safety. 56% of the UK public that we polled strongly supported rules which would require tech companies to protect children by restricting their experience of the metaverse, whilst only 33% strongly supported an agreement between metaverse companies to ensure their technologies were compatible.

The continuing growth of the video game sector has evidenced how important interoperability can be to shared experiences, however, with developers realising the huge potential that interoperability between games consoles, PCs and mobile gaming can have. Cross play, whereby users can connect with friends and players from other platforms, and cross-progression, where a single account for a game can be used by a user across any device have been features warmly welcomed by the gaming community. These features have increased player bases and playtime across games such as Fortnite, Call of Duty and Overwatch significantly, bringing together users from multiple platforms. Cross-players ended up playing Fortnite about 570% more on average than non cross-players according to Epic Games’ analysis, speaking to the power cross-platforms can provide both to user enjoyment and player base for developers. 

As the Metaverse continues to develop, platforms and developers will have to attempt to navigate both security and interoperability, to ensure that users are both safe, and able to move between worlds seamlessly. Creating a wild west of interconnected, unsecure virtual experiences would risk the safety and data privacy of the public, an issue our polling has found is already front of mind. Isolated metaverse bubbles on the other hand risk hampering innovation and creating ‘walled gardens’ that limit the metaverse's full potential.
