RMRK (pronounced "remark") is a set of standards on the Kusama blockchain which compose five "NFT lego" primitives. Putting these legos together allows a user to create NFT systems of arbitrary complexity. Additionally, by leveraging this logic and Kusama's multi-chain architecture, these NFTs are eternally liquid and forward-compatible with as yet unannounced projects, and seamlessly portable to any connected parachain. The RMRK Protocol (RMRK) is a unique set of NFT solutions built on the Kusama blockchain utilizing the Polkadot (DOT) network. The main goal of RMRK is to enable people to easily create next-generation NFTs which would be much more functional than most of the mainstream NFTs of today.

In simple words, the RMRK Protocol describes itself as “a set of NFT legos”, and also as a set of Kusama blockchain standards for building NFTs. Thanks to RMRK, anyone can create their own NFTs effortlessly, without having to know anything about blockchain technology or smart contracts.
