While not absolutely necessary, omitting it would be misguided. “The Metaverse without blockchains would likely just advance the ball for Big Tech.”
Many are thrilled at the prospect of the Metaverse with its virtual worlds that can be used to play online games, but also to train surgeons on 3D organ models and enable students to visit recreated villages in ancient Greece astonishingly brought to life.
Many assume, too, that blockchain technology will play a key role in the Metaverse, along with other emerging technologies such as artificial intelligence (AI) and virtual reality (VR). But, is the use of blockchain really a foregone conclusion?
Stanford University professor Jeremy Bailenson recently moderated a World Economic Forum panel with some of the world’s leading thinkers of the Metaverse and blockchain. “The first question posed to the panel was ‘Do we need the blockchain for the metaverse?’” Bailenson, founder of Stanford’s Virtual Human Interaction Lab, recounted to Cointelegraph. “The consensus was that the Metaverse could exist without blockchain.”
As an example, Bailenson offered up metaverse pioneer Second Life, founded in 2003, which has 70 million current registered accounts and is adding another 350,000 new accounts each month to its online multimedia platform. Second Life has developed “a robust economy where digital assets are bought and sold,” said Bailenson. “The typical GDP of Second Life is about half a billion dollars each year. And, the world runs robustly without using the blockchain.”
“Could the next iteration of the internet exist without blockchain technology?” asked Tonya Evans, professor at Penn State University’s Dickinson Law School. “Yes, it could,” she told Cointelegraph. After all, distributed decentralized ledgers and cryptographically-secured assets — including smart contracts — are only one part of Web3 technology, along with AI, 3D printing, VR, augmented reality, the Internet of Things (IoT) and others.
Exclude it at your peril
But, omitting blockchain technology, while doable, could still be a mistake. “The Metaverse without blockchains would likely just advance the ball for Big Tech,” added Evans, and it would come at the expense of those same people left behind by Web2 — “the very people a truly decentralized web would empower.”
Yonatan Raz-Fridman, founder and CEO of SuperSocial — which develops games for the Metaverse — agreed that blockchain technology is not absolutely necessary. “No, you don’t need blockchain to enable the Metaverse,” he told Cointelegraph. There is no a priori reason why avatars can’t be created in 3D and games played with closed platforms, like Second Life’s.
But, Web3 is arguably a reaction against the FAMGA companies — Facebook, Apple, Microsoft, Google and Amazon — with their privately-owned platforms, and Raz-Fridman predicted that companies like Meta will have to compromise on the matter of interoperability if they expect to participate. This means allowing avatars to freely travel from one Metaverse project to another — along with all their digital clothes and jewelry. As NYU marketing professor Scott Galloway put it recently:
“Why buy clothes if you can’t wear them out of the store? Why buy a Birkin bag if you can’t show it off in the Metaverse?”
Consumers are now demanding a Web3/Metaverse more like that depicted in Neal Stephenson’s 1992 novel Snow Crash, added Raz-Fridman, “where everyone owns their digital assets and has the freedom to bring them with them as they move from one place to another.”
All about people, places and things
The Metaverse is an elusive term — various parties define it differently. Most agree, though, that it involves immersive three-dimensional virtual worlds with lots of games and role-playing. Bailenson, for his part, finds it useful to break the Metaverse down into people, places and things. In each of these areas, he sees a potential role for blockchain technology.
“People are avatars, the bodies we wear while immersed in the digital world,” he explained to Cointelegraph. Here, blockchain technology can provide the “crypto DNA” that “ensures a one-to-one mapping of person to avatar.” For example, it could be used to guarantee that an individual can’t inhabit ten avatars simultaneously or enable someone else to “take my own avatar for a joy ride.” Added Bailenson:
“While an obvious application of blockchain will be to verify clothes and jewelry for an avatar, I have always thought the killer app here is documenting and verifying human animations.”
Places, in Bailenson’s conception, are set areas in a grid of a virtual world. For the Metaverse to work, a world “needs to be persistent: it is there, even when you aren’t, and consistent: if you buy a plot of land one kilometer from Snoop Dog, it can’t move farther away based on an arbitrary remapping of the world.” Some platforms are already using blockchain technology to document these maps, he noted.
Finally, the most obvious application of blockchain technology is in Bailenson’s realm of things, which includes three-dimensional models, two-dimensional images, sound files “or any digital asset that can be housed within a virtual world.” Blockchain technology can be used to verify transactions “without a centralized body overseeing the transaction” and also ensure “that items have unique value based on the supply — one can’t just make thousands of copies to counterfeit an asset.”
