NFTs, short for Non fungible tokens. Basically pieces of digital hashes that represent a real object (real in the relative sense the object can be digital as well). Now these hashes themselves are on a blockchain where you can verify the authenticity of the creator of the hash. The authenticity of the hash is established by the set of folks who will sign the blockchain. Thus NFT is a unique ID, digitally verifiable that represents some other “real” asset. Now why does this exist? Only time will tell :-)
