Abstract: There is an urgent need for efficient manufacturing solutions to be successful in increasing mass individualization demands. Under the tendency of personalization and servitization, social manufacturing has been proposed as a mass individualization paradigm is proposed. Since the centralized management platform can not meet the self-organizing demands among prosumers' community, which is usually oriented by emerging open architecture and open source product under social manufacturing context, a community construction model based on blockchain technique and its related computing paradigm. The configuration and operation methods of blockchain for community are presented, including the decentralized consensus algorithm, smart contract, multi-form typology and dynamic evolution of prosumers' relationship. A demonstrative prototype decentralized application developed based on Ethereum blockchain programming language is presented to validate the proposed model. The goal is to reduce the complexities of mass individualization in the dynamic production flows management, and improve the social characteristic and flexibility of work-in-process for individualized manufacturing demands.
