Abstract

The Aging of the Population has become a major challenge facing the community of shared future for mankind, and solving the problem of old-age care in the context of population aging has become an unavoidable social problem and a worldwide issue. In view of the problems existing in the model of community home-based elderly supporting in China, combined with the characteristics of decentralization and non-tampering of blockchain technology, the inevitability of the application of blockchain technology in the field of elderly supporting and its specific application form in Intelligent community are analyzed. The Intelligent community home-based elderly supporting system based on blockchain technology realizes” providing for the elderly and enjoying the fun", and provides data support for the development management and service quality monitoring of the industry of elderly supporting. 1 Research background 1.1 Background of population aging People and population are always the core of sustainable development. The trend of the global population development shows four characteristics: population growth, population aging, migration and urbanization.
