At present, the decentralized public memory technology led by IPFS tends to mature and has been widely used in various data memory business scenarios, especially in the fields of website construction, NFT data storage, and streaming media CDN. However, the data types saved in IPFS tends to be inactive and cold, which is difficult to adapt to the hot data frequently interacted and updated in mobile applications - it also requires high response requirements of real-time data access. For these reasons, it's difficult to use IPFS technology directly and widely in mobile applications.
