Abstract The current economic growth model has changed from efficiency development to innovation development. Ecological environment and other problems are still very prominent, the industry is lack of close integration, universities and scientific research institutions lack a sound science and technology service system. The purpose of this study is to explore the functions of eco-innovation ecosystem based on smart city blockchain, put forward relevant policy recommendations, and provide theoretical and practical guidance for the development of an innovation ecosystem. Through the methods of network survey, macro cluster analysis and typical case analysis, present study analyzes the development of derivative products and the research status of an innovation ecosystem. Blockchain can be regarded as a trusted distributed database. Four core mechanisms, namely P2P network communication mechanism, blockchain account book storage mechanism, password mechanism and consensus mechanismare used to ensure the distributed, tamper-proof and non-repudiation characteristics of the system, which makes the blockchain system "honest" and "transparent". It has the characteristics of a wide range, cross-subject, high efficiency and low cost in application. Taking the city as an example, this paper investigates the development of the green building industry and the relationship between the innovation ecosystem. The results showed that the α coefficient reliability index of all variables was above 0.8 in terms of ecological reliability and validity, which proved that all the scales in this study had good reliability, KM0 values were more than 0.7, and the degree of freedom was high, and all the scales had high convergence validity. Among the research objects associated with the ecosystem, "technological innovation" accounts for the largest proportion of 28% in the region, and the lowest proportion is 5% of high-tech enterprises.
