7. What is web3?
Web3
Web1
Interface is not a limiting factor in web3
anymore thanks to decentralized
ownership
In web3, decentralized ownership and identity
allows for multiple interfaces

8. What is Metaverse?

9. What is Metaverse?
“Snow Crash” by Neal Stephenson

10. What is Metaverse?
Web3 is the Metaverse*
The only problem was “who owns the
Metaverse”. It is solved by Web3.

11. Avatars: Web3 and ML capabilities

12. Examples from Spatial and Ready Player Me

(Cross-game, cross-metaverse
avatar)
Cross-platform avatars possible
thanks to Web3

16. ML (“AI”) motion capture
AI provides us with a free personal
artist for all our Metaverse
incarnations

17. Metaverse-ready NFTs (and other web3
assets)

18. Metaverse-ready (“Rich”) NFTs
These NFTs normally would have one or more of the following features:
● Metadata entries pointing to 3D models and textures or a ready bundle compatible
with Unity, Unreal Engine, Decentraland, Sandbox, Spatial etc
● May also include or support: full-poly and low-poly (lightweight) 3D models, video
and sounds, AR/VR features, file for 3D printing at home etc
● Mutable parameters impacted by object's exploitation in the Metaverse (for a digital
car, for example, that would be mileage, how much fuel left etc)
● Additional/Custom parameters improving the compatibility with certain applications
and metaverse platforms
● Rich NFTs would often be based on advanced NFT standards allowing more flexibility
and combinations of fungible + non-fungible tokens. ERC-1155 offers greater
flexibility in creating such composable tokens corresponding to real needs of
metaverse objects. E.g. limited edition car (1 / 1,000), unique aerography created by an
artist (1/1), fungible token for fuel tank etc.

22. State of infrastructure and tooling in “flat”
and “Metaverse” web3

23. Unity + Mobile + Web3 issues (1/2)

24. Unity + Mobile + Web3 issues (2/2)

25. L2 & zk for your Metaverse
implementation

26. L2 & zk for your “presence” and assets transactions
Using an L2 solution with zkRollup / zkSync technology, startups can
implement a decentralized presence mechanism and state without
prohibitive transaction costs. This is important to enable Metaverse
development.

27. Chat bots: from Web2.0 to Web3

28. Chat bots: from Web2.0 to Web3
● Query user for information (such as medical
in-take form, social profile etc)
● Book calls and appointments
● Reminders (medications, AI assistant etc)
● Commerce (use web3 for payments)
● DAO and community moderation (web3 for
governance)
● Trade digital assets (DeFi, Cryptocurrency,
NFT)
● Analyze your data (web3 for payment and
authorization)
● Independent actors (with own wallets)

30. Sign on and profile in Web3

31. Sign on and Profile in Web3 apps
Interface doesn’t matter. App doesn’t matter.
Web3 = user’s ownership
Health wallet app NFT / Social app

32. ChatGPT inside your app/product

33. ChatGPT inside your app/product

34. ChatGPT - healthcare use case (and
web3 connection)

35. Land and property ownership in reality
and in metaverse

36. Land/Property NFTs and ownership protections
https://satoshi-island.com/
● Land NFTs
● Citizenship NFTs
● Lands/Blocks allocation
● Build
● MiniDAO mechanism
Land protections
Rights and duties of “citizens”

37. Land/Property NFTs and ownership protections
Satoshi Island - Land NFTs: expanding standard ERC-721 with rights and protections.

38. Metaverse mode & “real” mode co-existing
Token & NFT proceeds used for real-world landscaping work.
Web3 identity (Citizenship NFT) used to access the place in Metaverse
and in real life.

39. Conclusions

40. Conclusions
● Internet is evolving. Web3 and Metaverse are already here (despite lacking
good looks and smooth transitions between apps and experiences for time
being)
● Things like EVM (Ethereum), SSI/DID, NFT, Metamask are the important
building blocks & are here to stay. Makes sense to learn more and integrate.
● Consider new approaches (e.g. Metamask sign-on ownership to the users,
‘trustless’ transactions via smart contracts, storing data in IPFS etc)
● Don’t worry about building your own metaverse, rather consider how you and
your products will blend into the web3 and metaverse world that evolves
around you
