Altcoins, or alternative currencies, are cryptocurrencies created specifically to try to correct the mistakes of Bitcoin, which has always been a point of reference for every cryptocurrency.
An avatar is a manifestation of a user within the metaverse. The avatar can be photorealistic, stylized, faithful to reality or completely different, it can be interoperable with other metaverses and wear wearables.
Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to serve as a medium of exchange independent of any central authority. BTC can be transferred electronically in a secure, verifiable and immutable manner.
Blockchain is a shared and immutable data structure. It is defined as a digital register whose entries are grouped into blocks, concatenated in chronological order, and whose integrity is guaranteed by the use of cryptography.
DeFi (Decentralized Finance) includes all those financial services that use smart contracts, automated executive agreements that do not require the presence of intermediaries and which, instead, use blockchain technology directly on the Internet.
Ethereum (ETH) is a decentralized network, created by Vitalik Buterin in 2013. The network consists of a globally decentralized open source computing infrastructure, which executes programs called smart-contracts.
An Exchange is a tool closely related to cryptocurrencies, a technological platform that allows you to exchange this financial product. Its function, therefore, is to be able to make the purchase and sale of cryptocurrencies possible.
In economic language, inconvertible paper money, generally accepted as a means of payment as it has been declared legal tender by the issuing state, regardless of its intrinsic value. (e.g. EUR, USD)
Interoperability is a concept that can be expressed on different levels (either at the level of the graphics engine, of links or of web3 via NFTs). Interoperability allows the interconnection of services, projects, digital assets and metaverses as a whole. The more interoperable a metaverse is, the lower its inherent risk.
The Internet of Things is the set of all those devices connected to the Internet and controllable through it. (Ex: Alexa and Google home)
The Map2earn is a feature of OVER the Reality that allows the scanning of an OVR-Land to recreate a neural network on which the user can support the AR experiences created.
Metaverse is a term coined by Neal Stephenson in Snow Crash (1992), a cyberpunk science fiction book, described as a sort of virtual reality shared via the Internet, where one is represented in three dimensions through one's avatar.
Most cryptocurrencies are extracted by so-called "miners", within transaction blocks called "mines", powerful computing centers that validate transactions by generating a new amount of cryptocurrencies. Graphics cards are usually used to achieve this.
NFTs (Non-Fungible Tokens), are a sort of "digital tokens", which are saved on the blockchain and unequivocally demonstrate that the owner of the token is also the person who owns the digital asset connected to it. It has become fashionable in the art world to assign ownership of digital works.
This is a non-player character from the metaverse (or video games). An NPC can be covered by a bodysuit, wear wearables and contain an AI (or simple interactions)
Open World (metaverso)
Term that refers to the gaming world where in some games it is possible to explore the entire world map without having a pre-established path
Persistence in a virtual world allows anyone to move objects that will remain in the new location for everyone (even when re-entering VR)
Polygon is a layer 2 of Ethereum, able to offer greater scalability and speed, with lower fees. The most appropriate UX for the consumer world still benefits from the security of Ethereum.
Proof of Stake
Proof-of-stake is a type of protocol for securing a cryptocurrency network and for obtaining distributed consensus. It is based on the principle that each user is required to prove possession of a certain amount of cryptocurrency.
Proof of Work
Proof of Work incentivizes miners to compete with each other in trade processing, receiving a reward in return. On some cryptocurrencies it is replaced by the Proof of Stake.
Virtual Reality (VR)
Virtual Reality represents a completely digital reality in which it is possible to move and interact through one's avatar.
Augmented Reality (AR)
Augmented reality is represented by a digital layer applied over reality (example: Pokemo Go)
Mixed Reality (XR)
Mixed reality is a concept that goes beyond augmented reality as it manages to merge real and virtual and not simply to superimpose them.
Unity - Unreal
Unity and Unreal are the two most used graphics engines in the world of video games and are starting to be used for metaverses as well.
A wallet or crypto wallet allows the sending and receiving of transactions on the blockchain.
Wearable in Web3 means the NFT clothing that our avatar can wear.
The term Web3 was coined in 2014 by Gavin Wood, co-founder of Ethereum and developer of Polkadot. Identify the phase of the internet in which it is possible to: 1. read 2. interact 3. possess. This is essentially only possible thanks to the blockchain and NFTs.
The term "Web 4.0" does not have a universally accepted and standardized definition, but usually refers to a future evolutionary perspective of the World Wide Web and associated technologies. Some of the characteristics often associated with the concept of Web 4.0 include the more advanced use of emerging technologies such as artificial intelligence, augmented reality, the Internet of Things (IoT), blockchain and other innovations.
In general, Web 4.0 is seen as a later stage than the concept of Web 3.0, which in turn focused on web semantics and advanced data interconnection. Web 4.0 could mean an even more personalized user experience, more advanced interactions between users and technology, as well as greater integration of the digital world with the physical environment through smart devices and advanced connectivity.
