[Purpose/meaning] In this paper, a unified scheme based on blockchain technology to realize the three modules of intellectual property confirmation, utilization, and protection of rights at the application layer is constructed, to solve the problem of unbalanced and inadequate resource distribution and development level in the field of industrial intellectual property. [Method/process] Based on the application of the core technology of blockchain in the field of intellectual property, this paper analyzes the pain points in the current field of intellectual property, and selects matching blockchain types according to the protection of intellectual property and the different decisions involved in the transaction process, to build a heterogeneous multi-chain model based on blockchain technology. [Conclusion] The heterogeneous multi-chain model based on Polkadot[1] network is proposed to realize the intellectual property protection scheme of a heterogeneous multi-chain model, to promote collaborative design and product development between regions, and to make up for the shortcomings of technical exchange, and weaken the phenomenon of "information island" in a certain extent. [Limitation/deficiency] The design of smart contracts in the field of intellectual property, the development of cross-chain protocols, and the formulation of national standards for blockchain technology still need to be developed and improved. At the same time, the intellectual property protection model designed in this paper needs to be verified in the application of practical cases.
