The States Members United Nations are believed to have started a program which can help refugees and displaced persons with the use of the blockchain technologies. The research is conducted within the WFP or World Food Program. Blockchain can secure data and this is the widely-known fact, but currently, there are no other working platforms which can serve as a total replacement for passport system.

This system, in fact, is already working. The first reports about it date back to July 2017. IrisGuard, a company from Jordan, has developed the mobile app called EyePay so that refugees could use a retinal clearance system to buy goods without credit cards. The database with the scan results belongs to the UN and based on the variant of Ethereum blockchain.

This innovative technology has replaced the old system of paper vouchers. In the end, this measure has saved $1.3 billion of the UN budget. According to the recent press messages, Belgium has invested $2 million in this program which will help to further improve the system.

While this certainly helps to reach a noble goal, one can easily imagine a corporate variant of the same technology used for much more malicious purposes. Because the data of transactions is stored on the blockchain too, it can be analyzed by big data scanning methods and clients can be manipulated in favor of the company. This is, however, only a theoretical possibility, as even without the wide use of blockchain databases, the world is already recognizing the dangers of big data manipulation and the private use of such blockchain systems may become forbidden in the future.
