The problem NFT MarketPlace with Creator Royalties solves

Digital ownership: In the digital world, it can be challenging to prove ownership of a unique asset. By leveraging the immutability and transparency of the blockchain, your NFT marketplace offers a solution to this problem by allowing creators to mint NFTs that represent unique digital assets and proving ownership of these assets.

Authenticity: In a world where digital content can be easily copied and distributed, it can be challenging to establish the authenticity of a particular piece of content. By using blockchain technology to verify and authenticate NFTs, your marketplace provides a solution to this problem, allowing buyers to trust that the NFTs they purchase are genuine and unique.
