Problems solved by technology

Due to the decentralized trading system of digital currency, there is no centralized authority that can freeze accounts, cancel transactions, etc., so it is almost impossible to prevent others from misappropriating assets in accounts
Similarly, if the user forgets his key, or loses control of the account due to unexpected circumstances such as sudden death, it is difficult to retrieve or inherit the assets in the account
Existing asset management methods try to solve some problems, but they often bring a series of new problems such as complicated technology, difficult to use and verify, centralized model brings security risks, and restricts asset circulation.
