The document outlines the concept of the metaverse as a persistent online 3D virtual environment where users can interact through identity, connectivity, and user-generated content. It discusses technologies enabling the metaverse such as VR/AR, decentralized storage with IPFS, and blockchain including Ethereum and NFTs. The roles of smart contracts and tools like Unity and A-Frame in creating metaverse experiences are also highlighted.

3. WHAT IS THE METAVERSE
The metaverse is a hypothesized iteration of the internet, supporting persistent
online 3-D virtual environments through conventional personal computing

4. METAVERSE Sci-fi book – Snow Crash
virtual universe made up of persistent,
shared, 3D virtual spaces in which users
can interact with other users.

6. METAVERSE VISION NOW
• Identity + Persistence + Connectivity
• User Generated Content and Economy
• Internet = Global connectivity
• Web = Internet + Persistent Content
• Social Network = Web + Identity + Social
Communication
• Metaverse = Social + Virtual Worlds +
Presence + Digital Human

20. IPFS
The InterPlanetary File System (IPFS) is a protocol and peer-to-peer network for
storing and sharing data in a distributed file system. IPFS uses content-
addressing to uniquely identify each file in a global namespace connecting all
computing devices.

21. IPFS
• Decentralization
• Location addressing -> Content addressing
• Partecipation

23. BLOCKCHAIN
A blockchain is a growing list of records, called blocks, that are linked together
using cryptography.

24. ETHEREUM
Ethereum is a decentralized, open-
source blockchain with smart
contract functionality. Ether (ETH or Ξ) is the
native cryptocurrency of the platform.

25. NFT
Ethereum also allows for the creation
and exchange of NFTs, which are non-
interchangeable tokens connected to
digital works of art or other real-world
items and sold as unique digital property.

26. SMART CONTRACTS
Smart contracts are simply programs stored on a blockchain that run when
predetermined conditions are met.

27. SOLIDITY
Solidity is an object-oriented, high-level language for implementing smart
contracts. Smart contracts are programs which govern the behavior of accounts
within the Ethereum state.
