Block chain-based NFT generation method, node and block chain

The invention discloses a block chain-based NFT generation method, a node and a block chain, which can be used in the field of block chains, and the method comprises the following steps: the Xth node of the block chain performs element disassembly based on NFT description information to obtain secondary elements; respectively sending each secondary element to a Y node to enable the Y node to execute an image synthesis step on the secondary elements; and the Xth node forms a second-level element image of the second-level element according to all the basic element information and the corresponding hierarchy and sequence, and generates an NFT image according to all the second-level element images. According to the invention, the generation randomness and the generation efficiency of the NFT image can be improved. 本申请公开了一种基于区块链的NFT生成方法、节点及区块链，可用于区块链领域，所述方法包括：区块链的第X节点基于NFT描述信息进行元素拆解得到二级元素；将每个二级元素分别发送至Y节点以使所述Y节点对所述二级元素执行图像合成步骤；所述第X节点根据所有基础元素信息及对应的层级和顺序形成所述二级元素的二级元素图像，根据所有所述二级元素图像生成NFT图像。本申请可提高NFT图像生成的随机性和生成效率。
