Abstract: 【Purpose/significance】The knowledge service under the distributed innovation mode is characterized by network structure
centralization, complex coordination and information asymmetry, which erodes innovation performance.Base on this, we propose the
knowledge-blockchain of distributed innovation mode, to enhance the enterprise knowledge service capability.【Method/process】So
firstly, from the perspective of knowledge service and blockchain technology, this paper puts forward the idea of knowledge-block‐
chain of distributed innovation; Secondly, analyzing the three-stage process of knowledge division, knowledge sharing and knowledge
integration of knowledge-blockchain, and the realization of cryptography technology, hash function and consensus mechanism in
knowledge-blockchain; Finally, taking Samsung electronics as a typical case of distributed innovation, the knowledge service interface
for block chain technology is built, the application of block chain technology in distributed innovation is solved.【Result/conclusion】
This paper constructs a new decentralized knowledge block-chain with traceable data and efficient services, setting tamper-proof,
transaction traceable, anti-counterfeiting signature and intelligent contract in one, it is beneficial to improve the performance of dis‐
tributed innovation【. Innovation/limitation】This paper does not involve empirical research，relevant ethical and legal issues on knowl‐edge-blockchain。
