Distory: A cross-border credit history

Distory’s hope is to further help people crossing borders

The problem

When you want to acquire a good or a financial service but promise to pay for it in the future, businesses typically look at your “credit history” before accepting. This is the case when you want to obtain a loan or a phone contract for instance. A credit history is a record of timely repayments of your credit card balance and utility bills in the past among other things. Landlords also look at your credit history when you want to rent a property.

The problem in Europe is that if you have a good credit history in one country (say Singapore), you typically cannot show it to a business, such as a phone company, in another one (say, Brazil). One typically has to build a new credit history from scratch in that country.

In other countries, such as Kenya, Tanzania, Uganda and Cameroon, the problem is even acuter: companies who have information on credit history mostly do not share it with a third party entity such as a Credit Reference Agency. When they do, not all of the information may be shared, and it may not be done efficiently.

The ability to assess credit risk is an important component in the pricing of a financial product. Financial theory since Harry Markowitz’s works on diversification has illustrated why it is important that riskier entities pay more for borrowing than less risky ones. Numerous organisations highlighted the lack of a cross-border and cross-financial institution credit history system in Europe and Africa.

Intuitively, a lack of credit history leads to a situation where individuals/companies who could borrow cheaply may not access various forms of credit (bank loans or phone contract for instance). This implies that some mutually beneficial deals may not happen. It can also lead to a situation where individuals/companies who borrow overpay with respect to the risk they actually cause to the company. Both these consequences imply a loss of welfare for individuals and most likely for society in general (individuals, firms and governments altogether).

Therefore, both lenders and borrowers will benefit from improved credit history sharing. Lenders through improved risk pricing and borrowers through both increased access to, and better priced, financial services.

Our proposed solution

Considering these issues, we propose to create Distory: a transparent, reliable and portable credit history. More specifically, Distory aims to establish an open-source cross-border credit history directory using a blockchain (Ethereum).

The way our solution will work, when one (customer or business) repays something, somewhere, a business or another person will be able to see a trusted proof of it anywhere in a fast, easy and efficient way. We use Ethereum’s blockchain to provide a stamp of authenticity to the most vital pieces of information. We aim to provide a solution oriented at performance using RESTful APIs. Careful and appropriate consideration to issues around identity verification, privacy and storage cost has been at the heart of the design of our solution. Failing to address these issues would significantly damage the reputation of our solution.

Our competitors are existing “credit history” companies. We know that the incumbents are currently investigating the option to develop cross-border solutions. We anticipate that it might be relatively hard for existing credit history companies to build cross-border solutions because of the inflexibility of their legacy systems. We are hoping to provide a more efficient solution using the relevant latest technological developments. We also aim to develop a solution that can scale up on mobile platforms as this is important for it to be relevant in Africa.

The key monetisation channel comes from offering a service to businesses. The value for businesses it to find information about the trustworthiness of consumers who do not appear on existing credit history platforms. This is likely to lead to additional and earlier sales.
