Non-fungible Tokens (NFTs)


Non-fungible tokens (NFTs) are unique digital assets representing ownership or proof of authenticity of a specific item or piece of content, typically using blockchain technology. Unlike cryptocurrencies like Bitcoin, each NFT is distinct and cannot be exchanged one-to-one, making them “non-fungible.”
