Blockchain technology plays a key role in the development of the metaverse in several ways:
1) It allows for data trust and reliability by providing a secure and decentralized record of transactions.
2) Blockchain ensures data security and decentralization by storing data across many nodes.
3) Smart contracts facilitate interactions and regulate relations between participants in the metaverse.
4) Non-fungible tokens (NFTs) will be essential for proving ownership of digital assets in the metaverse.

5. What is Blockchain
Technology?
A Blockchain is essentially a digital ledger of
transactions that is duplicated and distributed
across a P2P network of computer systems . It is
able to record information in a way that makes it
difficult or impossible to change, hack, or cheat
the system.
Smart contracts are simply programs stored on a
blockchain that run when predetermined
conditions are met. They typically are used to
automate the execution of an agreement so that
all participants can be immediately certain of the
outcome, without any intermediary's involvement
or time loss.
Smart contracts
8. Fungible and Non-Fungible Tokens
in Metaverse
In a blockchain, Fungible tokens are cryptocurrencies like Bitcoin (BTC). Nonfungible tokens are units of data that
represent a unique digital asset stored and verified on the blockchain.
9. Blockchain Protocols in Metaverse
ERC-20, and ERC-721 protocols are the Secret of importing Blockchain in Metaverse
"ERC-20" (Ethereum Request for Comment) refers to a
scripting standard used within the Ethereum blockchain. This
technical standard dictates a number of rules and actions that
an Ethereum token or smart contract must follow and
implement. ERC-20 introduces the token standard for creating
fungible tokens on the Ethereum Blockchain. Plenty of well-
known digital currencies use the ERC-20 standard, for
example Bitcoin, Ether (ETH) and Litecoin
"ERC-721" is an open standard that describes how to build
Non-Fungible tokens on Ethereum Blockchain. It’s
specialized in NFTs, which means a token developed abiding
by the rules of ERC-721 can represent the value of any digital
asset that lives on the Ethereum blockchain.

11. Why Blockchain is a key Player in
Metaverse
Data Trust and Reliability
After the 4th industrial revolution, we have a
question about the reliability of data about
whether the real thing is becoming data
accurately and completely in the virtual world.
In the virtual world, trust technology is
emerging as an important issue.
We can think of blockchain as one of these
trust technologies.
12. Why Blockchain is a key player in
Metaverse
Data Security
The fact that the Metaverse stores data measured in
Exabytes raises the question of safe storage,
transmission, and synchronization.
In this sense, blockchain technology is very relevant
in the context of decentralization of storages and
data processing nodes.
13. Why Blockchain is a key player in
Metaverse
Decentralization.
To ensure the full functioning of the Metaverse,
all participants must see the same virtual
world.
A decentralized ecosystem based on blockchain
technology allows thousands of independent
nodes to synchronize.
14. Why Blockchain is a key player in
Metaverse
Smart Contracts.
These make it possible to effectively regulate
economic, legal, social, and other relations between
ecosystem participants within the Metaverse.
In addition, smart contacts allow you to develop and
implement the basic rules for the operation of the
Metaverse.
15. Why Blockchain is a key player in
Metaverse
Interoperability.
Blockchain facilitates the joint interoperability
and functioning of different systems and interfaces
without restriction. This is especially relevant when
it comes to NFT (Non-fungible token) valuation
and turnover.
16. Why Blockchain is a key player in
Metaverse
Money Transactions
Cryptocurrency, being an integral part of the
blockchain, can act as a properly working analog of
traditional money; and via the Metaverse crypto it
is an effective way to perform mutual settlements.
17.
18. Non-Fungible Tokens (NFTs)
Non-Fungible Tokens (NFTs).
According to many experts, non-fungible tokens (NFTs)
will take up a key role in the Metaverse. Acting as proof
of ownership of digital assets.
NFTs have an enormous potential to be integrated into
any Metaverse crypto projects related to the purchase of
any game assets, avatars and so on.
NFTs will be used to assign a certificate to specific
digital assets, and avatars against assets cloning
19. Gaming
Many blockchain experts are saying that games will soon become
the area where the concept of the Metaverse really gets going.
They predict that virtual assets used by the players will be presented
in the form of non-fungible Metaverse tokens
1) Star Atlas: is a Metaverse-meet-crypto Role
Playing Game (RPG) where players can time-
travel into the futuristic setting in the year
2620 and explore the cosmos with virtual
experiences.
2) The Sandbox: is a blockchain game where users explore a
virtual world containing NFTs. user-created environments, and
other content. Players create their own avatar and digital
identity, a key concept for the Metaverse. An avatar can be
associated with a crypto wallet to manage a player's NFTs,
SAND tokens, and other blockchain assets.
20. Virtual Currencies
One of the Metaverse examples of the use of virtual
currencies in the Metaverse is MANA which is used to buy
virtual property in the game Decentraland”
In the future, users will be able to buy virtual analogs of
everything that can be purchased in the real world. This
technology will not be limited only to games: the
dynamically developing niche of DeFi may well become a
testing ground for virtual lending, borrowing, investing,
and trading within the Metaverse.
Thus, the scope of cryptocurrency appears theoretically
unlimited.
21. Self-Identity Authentication
In the Metaverse, self-identity authentication (or Self-
sovereign identity (SSI)) is an approach to digital identity
that gives individuals control of their digital identities. It is
accomplished in the same way as the assignment of a social
security number. (Avatar/holygram identity)
All data about a specific user such as age, activity,
appearance, and other characteristics are stored in the
Blockchain as an SSI number. This ensures maximum
transparency and prevents illegal activities in the
Metaverse.
In addition, self-identity authentication eliminates the
possibility that someone will commit illegal actions under
a false name within the virtual ecosystem.
22. Real Estate
Real estate is one of the main digital assets in
the Metaverse. The chief concerns here are: how
to assess a virtual real estate object, and how to
regulate this market if the Metaverse actually
represents an infinite digital space.
This is where the Metaverse blockchain can be
used as a kind of registry that records all actions
performed with virtual real estate assets, such as
creation, change, purchase, sale, or disposal.
23.
24. The Sandbox
The Sandbox (SAND): It is practically a
blockchain game in the Metaverse, which allows
users to explore a virtual world.
The virtual world in The Sandbox includes
NFTs, user-created environments as well as other
content.
Players could create their own digital avatars
and identities, which they can link with a crypto
wallet for managing their NFTs and SAND
tokens as well as other blockchain assets.
25. Decentraland
Decentraland (MANA): it is a 3D Metaverse where
users can create avatars, buy and equip the land plots,
organize various events and create digital content.
The domestic economy of Decentraland operates on
the blockchain which enables digital identification and
confirmation of in-game assets ownership.
The main digital asset in the game is virtual real estate
(LAND).
Moreover, the Metaverse has a native ERC-20
cryptocurrency token (MANA) which is used as an
internal means of mutual settlement between the
players.
26. Star Atlas
Star Atlas (DeFi): is one of the most innovative
Metaverse crypto projects.
It is a new gaming Metaverse built on the
foundations of multiplayer video games, real-
time visuals and experiences, decentralized
financial technologies, and blockchain.
The players of “Star Atlas” can purchase digital
assets such as land, spaceships, equipment, and
crew.
27. Enjin
Enjin (ENJ): It is a unique implementation of the
Metaverse concept. It not only operates on the blockchain
but also offers opportunities for developing software for
the easy creation of NFT.
It involves a secure Ethereum-based NFT development
platform.
The system also ensures digital assets are highly liquid by
converting Enjin NFT into ENJ Metaverse tokens.
28. Bloktopia
Bloktopia (BLOK): is a Metaverse example built on top
of the Polygon blockchain where you can learn, earn
money, play games, and create all in virtual reality.
Bloktopia has an integrated play-to-earn game
implemented through the internal Metaverse token
BLOK and in addition provides advertising opportunities
for Adblok.
It also allows you to sell real estate via Reblok, and gives
you the chance to create your own gaming immersive
environments and enjoy various games within the
Metaverse

30. FAQs
What coin will be used in Metaverse?
Currency to be used in Metaverse is still not decided and
will depend on the preferences of users and creators.
However, it is most likely that Metaverse will allow
multiple Blockchain-based crypto currencies like Bitcoin
or Ethereum that can even be exchanged in real world.
On the other hand, Currently there are different crypto
currencies used across diverse Metaverse platforms.
Decentraland uses MANA, and Robolox uses Robux.
However, multiple cryptos might be allowed in the future
as Metaverse develops.
31. FAQs
Can Metaverse make you rich?
Business opportunities in Metaverse are
endless and depends on the creativity of users
and entrepreneurs. However, like most things
in life, there is no guarantee that everyone
will become rich in Metaverse. It all
depends on how you use this new virtual
world.
You can invest by buying up digital assets on
sale in the Metaverse or you can invest in
tokens and cryptocurrancy exchanges
32. FAQs
Why Metaverse involve holograms (or Avatar)?
What the role of Blockchain with these hologram?
Metaverse will integrates many state-of-the -art
technologies like VR and AR allowing users to
experience a Virtual design like real. Holograms are
used to create a realistic 3D image of the user that can
be used for an immersive Metaverse experience.
Holographic collectibles will be registered on the
blockchain with each instance individually tracked
and sold according to programmable logic
33. FAQs
Can Metaverse be hacked?
Metaverse will closely be tied up with
blockchain technology, making it secure
and tamperproof.
However, like any other system,
Metaverse might have loopholes and
vulnerability that can be exploited. For
example, exploiting vulnerabilities in
smart contracts
34. FAQs
Can Metaverse fail or Stop?
Metaverse is still in its early developmental stages and
has a long way to go. Like any other new concept, it
might fail if it doesn't meet the expectations of users or
fails to live up to its hype.
However, the current trend and vison of Metaverse is
very promising and less likely to fail. There are already
games and businesses that are thriving on the concept of
Metaverse.
Metaverse is not a physical entity, so it can't be stopped.
Peer to peer network, decentralization and blockchain
technology will make it virtually impossible to stop
Metaverse.
35. FAQs
Can Metaverse work without blockchain?
Metaverse is a concept while blockchain is a
technology that makes Metaverse so huge.
Digital asset, ownership and Metaverse currency
couldn't exist without blockchain technology.
Although, a technology like Metaverse could exist
even without blockchain, it won’t embed the core
features of true Metaverse.
