Abstract

According to the block chain-based entity mortgage lending method provided by the invention, a user is allowed to use entity assets as mortgage, and a borrower directly interacts with a protocol to pay a floating interest rate. According to the invention, storage and taking are carried out at any time, no early stage exists, no so-called service charge exists, interest can be borrowed for a long time, the interest rate floats in real time according to the market, no black screen exists, and the fairness of the transaction is ensured. After the mortgage state of the mortgage is changed, the borrower can borrow the digital currency from the platform, and the problem of double money is prevented. Zero-knowledge proof is adopted and used for proving and verifying related parameters in the transaction process, relative sensitive data such as account balances and entity asset information of all users can be well hidden, use and storage of the zero-knowledge balances are verified through the zero-knowledge proof, new zero-knowledge balances are used for replacing old zero-knowledge balances, and therefore, the personal privacy of the user is protected.
