Non-Fungible Token (NFT) is a blockchain-based digital asset that uniquely signifies its owner. For example, any digital data e.g., images, songs, etc. can be minted as NFTs. Recently, huge transactions are taking place in buying and selling of digital arts as NFTs. In the future, this technology will evolve towards other applications like land ownerships and many more.
Currently, most NFTs are minted on the Ethereum blockchain, and each NFT existence on the network can be verified using the etherscan.io platform. In the future, other leading blockchain networks like the Binance Smart Chain and the PolkaDot can facilitate NFTs creation.
For example below art samples can be used as NFTs, once minted on the Ethereum blockchain.
