NFT's or Non Fungible Token's are a new technology phenomenon allowing clear ownership and easy transferability of digital art. This property means each token is unique and cannot be swapped identically for another token ever. NFT can be most anything digital, such as art, images, videos, music, memes, and tweets. The process of creating NFTs is “minting”, similar in concept to metal coins that are minted (stamped) to confirm their legitimacy. Minting an NFT produces a one-of-a-kind token on the blockchain and an electronic certificate of authenticity. NFT Marketplace for Images is used to generate the cryptoboy using the NFT, Blockchain, Cryptocurrency. The generated cryptoboy can be sold and they can see who is the token owner and also token metadata.
Features:1)Mint custom ERC721 implemented Crypto Boy Tokens. 2)Sell Crypto Boy tokens on the marketplace. 3)Set desired token price. 4)Toggle between keeping the token for sale and not for sale. 5)Keeps track of all the tokens owned by an account - minted and bought. 6)Query blockchain for the token owner and token metadata. 7)User can mint a token only after every 5 minutes. Scope: NFTs used in cryptoboy are digitally unique, no two NFTs are the same. Every NFT used in cryptoboy must have an owner and this is of public record and easy for anyone to verify.
Technological Innovation:1.NFT: NFTs are unique cryptographic tokens that exist on a blockchain and they cannot be replaced or copied/paste a new NFT into existence it is recorded in a blockchain. And that is used to certify authenticity and ownership as a digital asset. It’s generally built using the same kind of programming as cryptocurrency, like Bitcoin or Ethereum, but that’s where the similarity ends. 2.Blockchain: Blockchain is a system it is used to record information in a way it makes difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain. The primary use of blockchains is as a distributed ledger for cryptocurrencies such as bitcoin. 3.Cryptocurrencies: Mostly cryptocurrencies use blockchain technology to record transactions, in which transactions are verified and records maintained by a decentralized system using cryptography, rather than by a centralized authority.
