Abstract: [Purpose/Significance] Intangible cultural heritage, as a typical representative of excellent traditional Chinese culture, have extremely high social value and cultural value, and the current intangible cultural heritage digital resources development work has made some progresses. However, the distribution of resources is fragmented, displaying the resource "island" phenomenon, and the developers are difficult to form a synergistic effect, user's requirements and live condition, input and output are difficult to balance, leading to the outcome are affected. Therefore, we use the NFT to organize intangible cultural heritage digital resources development, which can better realize the dissemination and inheritance of intangible cultural heritage. [Method/Process] According to online survey and literature research, this paper analyzes the deep problems of the intangible cultural heritage digital resources development, introduces the key technology of NFT, which including smart contracts and blockchain, discusses the feasibility in intangible cultural heritage digital resources development. At the subject level, the development based on NFT integrates the strength of various institutions, promotes the multi-developer cooperation. At the method level, the development meets the three needs of users and realizes the live development. At the economic level, the balance between input and output has been achieved, and economic and social values are unified. In addition, this paper puts forward the development architecture based on NFT according to the characteristics of intangible cultural heritage digital resources, which can be divided into network layer, consensus layer, contract layer, resource layer and user layer from bottom to top. Then we expound the application processes and implementation strategies. [Results/Conclusions] The NFT has many advantages in transactions. For example, digital collection transactions record ownership and its flow on a blockchain, the whole transfer process is open and transparent, solving the problem of authenticity of the collection. What's more, NFT brings a new confirmation model, in the new model, the entire blockchain recognizes the sole ownership of the owner, which has revolutionary significance for intellectual property protection. Based on the blockchain, we introduced the NFT into the intangible cultural heritage digital resources development, which is conducive to the copyright protection and develop traceability, provides a reference path for the fine-grained intangible cultural heritage digital resources development. In addition, the architecture has a certain universality, and it needs to be combined with the specific intangible cultural heritage project, resource type, digital format and other personalized requirements. With the maturity of the Meta-Universe ecology, intangible cultural heritage digital resources, as a potential cultural resource, can be further innovated and developed, and derive more forms.
