    What is NFT?
    NFT is a cryptographic token, each instance of which is unique and cannot be exchanged or substituted for another similar token. It runs on the blockchain.
    
    A blockchain is essentially a digital ledger of transactions that is replicated and distributed across a network of computer systems on a blockchain. Each block in the chain contains a number of transactions, and every time a new transaction occurs on the blockchain, a record of this transaction is added to the ledger of each participant. A decentralized database managed by multiple participants is known as distributed ledger technology (DLT). All this makes it difficult or impossible to change, hack or cheat the system.
