Thank you @levycore for the lesson and Home Work Task.

Describe one popular project that uses Non-Fungible Tokens (NFTs)
A Non-Fungible Token (NFT) is best to be used on systems that provide collectible items, get admission to keys, lottery tickets, numbered seats for concert events and sports matches, etc.
These Non-Fungible tokens (NFTs) have captured a lot of developer minds in view that the interface was first published as an EIP in September of 2017. Non-Fungible tokens allow developers to tokenize possession of any arbitrary data, drastically growing the format house of what can be represented as a token on the Ethereum blockchain.
The biggest differentiator of Non-Fungible tokens is that every one is tied to a exceptional identifier, making every token special to its owner. This is an awful lot one-of-a-kind to tokens leveraging the ERC20 token standard, which is a token general for fungible tokens, meaning every token is interchangeable. Looking at the ERC20 token standard, builders can create any quantity of tokens within one contract, however in the ERC721 token standard, each token inside the contract holds a distinct value. ERC721 is a wellknown interface for Non-Fungible tokens, meaning ERC721 tokens are certainly a subset of Ethereum tokens.
What is ERC-721?
Ethereum’s general ERC-721 is the most frequent for NFT tokens, whilst cryptocurrencies (on Ethereum) are based totally on the ERC-20 standard. These requirements are pretty similar, without for the truth that ERC-721 tracks possession and actions of person tokens in a block, which allows the blockchain to apprehend the non-fungible tokens. Ethereum is the most famous blockchain for NFTs, but there are other blockchains helping these tokens, like NEO, WAX, and TRO.
The ERC-721 introduces a widespread for NFT, in other words, this kind of Token is special and can have distinctive value than some other Token from the identical Smart Contract, perhaps due to its age, rarity or even something else like its visual. The ERC-721 (Ethereum Request for Comments 721), proposed by means of William Entriken, Dieter Shirley, Jacob Evans, Nastassia Sachs in January 2018, is a Non-Fungible Token Standard that implements an API for tokens within Smart Contracts.
It offers functionalities like to switch tokens from one account to another, to get the current token balance of an account, to get the owner of a particular token and also the whole grant of the token accessible on the network. Apart from these, it also possess some other functionalities like: to approve that an quantity of token from an account can be moved through a third party account. Once ERC-721 Non-Fungible Token Contract is deployed, it will be responsible to preserve tune of the created tokens on Ethereum.
Understanding The Standards of ERC721
Like previous token standards, the ERC721 widespread outlines a set of frequent guidelines that all tokens can comply with on the Ethereum community to produce predicted results.
ERC721 is important for a wide variety of reasons, in particular because of the new use cases it enables as nicely as its ability to be effortlessly built-in into ecosystem infrastructure. Having a common interface for change and pockets operators to easily put in force makes Non-Fungible tokens that an awful lot extra valuable. Assimilation into the ecosystem makes them extra liquid, increases rate discovery, and approves all people in the world to personal Non-Fungible assets.
Assimilation into the ecosystem can’t be duplicated or seized. There have been a quantity of games that constructed their platforms on pinnacle of the ERC721 token standard. Decentralized lets in users to buy scarce, digital land in the metaverse through tokenizing each parcel of land to a special token. Non-Fungible tokens have the possibility to run out lots of liquidity in gaming belongings and create totally unique gamer experiences.
