A New Home-Based Pension Mutual Aid Framework Based on Blockchain

In the context of the public’s response to home-based care, the “Time Bank” care model has attracted more and more attention as an effective supplement to home-based care. Although there are cases of Time Bank implementation in China, it still has many problems such as extreme centralization, lack of credibility, and opaque and imperfect circulation of time currency. In response to this, this paper integrates blockchain technology based on the traditional time banking model and proposes a new home-based care mutual assistance framework driven by blockchain technology, which utilizes the distributed decentralization, collective maintenance, and data immutability of the blockchain. The characteristics of the blockchain provide credit guarantees by combining the community-based management agency and the channelization of the service network. Time-based transaction process service matching, smart currency scoring module. And use their respective financing agreements and other technologies to safely circulate, jointly establish a chain-wheel interoperability chain, and cooperate with various contract models to jointly establish various on-chain contracts. Experimental analysis shows that the new framework involved can realize secure encrypted storage and transmission of information, solve the problem of cross-regional storage and exchange, and provide a new feasible solution for home care.
