Of course the client must have a positive credit reputation if the company can issue loans without collateral. But if he first applied for a loan, the company cannot know how much creditworthiness of the client. Perhaps the company needs certain documents confirming the creditworthiness.
Of course, we need documents and certificates of income, so no one just gives loans, we need real data
I think that if there is such a database on blockchain technology then it will be easier for the company to decide on the possibility of granting loans. Thus the client does not need to prepare a package of documents every time.
