UniArts’ NPoS mechanism requires creators to mint NFTs with their works and bind their address with a running node to become the validator candidate. Holders of UART tokens can nominate preferred NFT validators and earn additional UART in the process. UniArts’ NPoS mints a portion of the block reward into NFTs, which bind validators and creators. NFT owners may choose to pin the NFT on their address to retrieve UARTs. Nominators vote for NFTs instead of nodes to gain staking rewards.
