What is the 'metaverse'? This guide explains the hype, exploring the core concepts of persistent virtual worlds, digital identity, and the player-owned.
The word metaverse gets used to mean many different things. In practice it points to the same idea: a set of shared, three dimensional virtual spaces where you show up as an avatar, keep your identity and items as you move, and transact in a working economy.
That vision is not one product. It is a collection of technologies, standards, and communities that may connect over time. Some parts exist today. Many parts do not yet. This guide defines what people mean by metaverse, who it is useful for now, how the pieces fit together, and where Web3 adds something distinct.
The most widely cited definition comes from Matthew Ball, author of The Metaverse: And How It Will transform Everything. He describes it as "a massively scaled and interoperable network of real-time rendered 3D virtual worlds that can be experienced synchronously and persistently by an effectively unlimited number of users with an individual sense of presence, and with continuity of data, such as identity, history, entitlements, objects, communications, and payments." The World Economic Forum reproduced this definition in its January 2023 briefing Interoperability in the Metaverse.
The term itself is older. Science fiction author Neal Stephenson coined metaverse and avatar in Snow Crash in 1992. The book described a street-like virtual world entered through a personal device. Early online worlds tried versions of that idea, from Second Life in 2003 to Fortnite concerts and Roblox experiences in the late 2010s.
A metaverse is not the same as virtual reality. VR is one way to enter. You can also enter through a browser, desktop app, or phone. A metaverse is not a single game, not a virtual economy by itself, and not an app store. It is the network that would let those games and economies connect.
Ball lists seven attributes that most technologists agree are required:
Today no platform satisfies all seven. What exists are early attempts that implement some of them.
This is for you if you are:
If you only need a virtual office for video meetings, you likely do not need a blockchain-based world. Tools like Microsoft Mesh for Teams or Zoom's immersive view already handle that without wallets or tokens.
Three things need to work together for a metaverse to feel real.
First, concurrency. The internet was built to send files between one server and one client, not to keep hundreds of thousands of clients in tight sync. Games work around this by splitting users into shards or instances. Fortnite's 2019 Marshmello concert showed about 11 million participants, but split across more than 100,000 instances capped near 100 users each. Larger synchronous crowds are still a research and infrastructure problem.
Second, standards. The open web works because of shared formats like HTML and common protocols. Virtual worlds need similar agreement for 3D assets, identity, payments, and permissions. Groups like the Metaverse Standards Forum, the Khronos Group with OpenXR and glTF, and Pixar and Nvidia with OpenUSD are trying to define how a 3D object or scene is described so different engines can read it. No single stack has won.
Third, content worth visiting. Platforms fill only when there is a reason to be there. Teens gather in Fortnite not to play a story mode but to hang out where their friends already are. Brands add temporary activations on top of that existing social graph. Without that, spaces stay empty even if the technology works.
Not all metaverse work is consumer social. Nvidia Omniverse is used in manufacturing and design to build digital twins, which are simulation-ready copies of physical products, factories, or processes. On March 18, 2024, Nvidia announced Omniverse Cloud APIs that stream OpenUSD scenes rendered in its cloud to Apple Vision Pro, with a demo of a car configurator. Apple released Vision Pro in the United States on February 2, 2024 and positioned it as spatial computing rather than a metaverse headset, a point widely noted after years of metaverse hype fatigue. These industrial uses are growing faster than consumer virtual worlds and often avoid blockchain entirely.
A central question is who controls identity, assets, and payments. Most large consumer platforms are closed. Your Fortnite skins stay in Fortnite. Your Roblox items and Robux balance stay on Roblox servers. Your Meta Horizon profile is owned by Meta. Those companies set fees, data rules, and what can be moved.
Web3 projects argue for an open alternative where rules are public and assets are portable. The approach uses public blockchains, typically Ethereum, and open token standards. Three mechanisms matter.
In open worlds, items are issued as non-fungible tokens that you hold in your own wallet.
This does not mean the item works everywhere. A voxel hat made for The Sandbox will not automatically appear in Decentraland. Portability depends on both worlds supporting the same file format and choosing to honor the same token.
Instead of separate logins per world, a Web3 identity travels with your address.
This makes your inventory and login portable in principle, even if each world renders your avatar differently.
When assets are onchain, finance can be built in.
These are live Web3 worlds, not concepts. Use them to see what works and what does not.
| Platform | What it is | Key details you can verify |
|---|---|---|
| Decentraland | Browser-based virtual world on Ethereum, governed by a DAO | Built by Ari Meilich and Esteban Ordano starting in 2015. Genesis City contains 90,601 LAND parcels as ERC-721 tokens on Ethereum. MANA is the ERC-20 utility token used for LAND, wearables, and DAO votes. Control of core contracts was transferred to the Decentraland DAO in 2021. Scenes are built with a builder tool or SDK. Clients run in a browser via WebGL, with desktop clients also available. |
| The Sandbox | Voxel-based world on Ethereum and Polygon, built by Pixowl and now run by Animoca Brands | Map contains 166,464 LAND parcels as ERC-721 tokens. SAND is the ERC-20 token with a 3 billion max supply, used for purchases, staking, and governance. Creators use VoxEdit to model voxel assets and Game Maker, a no-code visual scripting tool, to build experiences. Polygon support was added to lower transaction fees. |
| Otherside by Yuga Labs | Browser-based world tied to Bored Ape Yacht Club, with land called Otherdeed | Launched with 55,000 Otherdeed NFTs in April 2022, generating about $320 million in primary sales. The central hub Koda Nexus went live in November 2025 and is accessible via browser without owning land. Otherdeeds include resources and artifacts that connect to evolving gameplay. ApeCoin and ApeChain are used for economy and transactions. |
For comparison, closed platforms you may already know are much larger. Roblox reported about 52 million daily active users in Q2 2022, Second Life averaged about 200,000 daily users in that period with 70 million registered accounts, and Fortnite regularly posts tens of millions of monthly participants. Those worlds do not give you onchain ownership, but they offer lower friction and far more populated spaces.
Be cautious with numbers. In October 2022, DappRadar reported 38 daily active wallets interacting with Decentraland smart contracts and 522 for The Sandbox. Both teams said that method undercounted, because many users log in and socialize without making an onchain transaction. Decentraland said it saw about 8,000 daily users at that time by its own definition of logging in and moving out of a starting parcel, and later reported 56,697 monthly active users in September 2022 with 1,074 wallets interacting with contracts. The Sandbox reported about 39,000 daily users and 201,000 monthly users during its Alpha Season 3. Definitions change, so compare methodology before comparing headlines. As of 2024 to 2025, independent estimates still show concurrent users in the hundreds to low thousands at any given moment for these Web3 worlds, not hundreds of thousands.
You do not need to buy land or tokens to look around. Start as a visitor, then add ownership only if you have a clear use.
Keep expectations modest. Most experiences are experimental. If you go to meet people and test creation tools, you will learn more than if you go expecting a replacement for the web.
No. VR is one display option. Most Web3 worlds today are entered through a browser or desktop app. Apple Vision Pro and Meta Quest add mixed reality options, but the core idea is a connected set of virtual spaces, not a specific headset.
No. Closed worlds like Roblox, Fortnite, and Horizon work without a wallet. You need blockchain only for the open version where you hold items as NFTs in your own wallet and move them between supporting worlds. Review what are NFTs and what is Web3 before you decide.
In Decentraland and The Sandbox, owning a LAND NFT lets you deploy a scene or game to a specific coordinate, host visitors, and set permissions or rental terms. It does not give you physical land rights, guarantee traffic, or promise returns. Location matters only insofar as other users choose to visit nearby.
Because there is no shared standard for avatar rigs and item metadata. Each engine expects different model formats, scales, and rigging. Interoperability efforts like OpenUSD, glTF, and ENS-linked avatars aim to fix this, but adoption is early. Even when a token is portable, rendering is not automatic.
Distinguish wallet interactions from visitors. Onchain counts track transactions, which miss people who just walk around. Platform counts track logins, which can count brief visits. Look for the definition the source uses. Cross-check DappRadar onchain numbers with the project's own analytics and with offchain sites that track concurrent visitors.
Technical risk is low concurrency and weak interoperability. Market risk is high volatility for MANA, SAND, and LAND, and low liquidity for parcels. Usability risk is wallet loss, phishing, and gas fee surprises. Check contract approvals, use a hardware wallet for larger holdings, and start with amounts you can lose.
Where do industrial uses fit?
Nvidia Omniverse and similar digital twin platforms let teams design and simulate products and factories in 3D. Those workloads often run on private clouds without tokens or wallets. They show that large-scale 3D collaboration has value even if consumer Web3 worlds remain small.
