    The World Identity Network (WIN), the United Nations Office for Project Services (UNOPS), and the United Nations Office of Information and Communications Technology (UN-OICT) are partnering to launch a pilot initiative that will use the blockchain technology to help combat child trafficking in Moldova. A first in the world, this project is part of a broader effort titled “Blockchain For Humanity”, announced during the Blockchain Humanitarian Summit in New York, on November 10, 2017.

    Still the poorest country in Europe, Moldova has been trying to stop child trafficking for decades. The Government of Moldova is an official partner in this Global Challenge, believing that this breakthrough technology can be leveraged beyond commercial applications, for the social good.


    The Global Challenge will result in a detailed concept and project design that could be further enhanced and used by the Government of Moldova for project implementation. However, the concept should be scalable and applicable to other contexts as well, including other countries around the world, where the prevalence of child trafficking is high.


    The winner of the challenge will:

    • Be offered the opportunity to have an advisory role in the further development of the submitted solution.
    • Be featured at the United Nations Press, the Unite Ideas platform and more broadly in press and social media.
    • Be offered the opportunity to pitch the solution for potential investment from WIN and other interested organizations.

    *Please note that the winner of the Global Challenge is not automatically guaranteed award of contract for project implementation, nor investment or grants from potential donors.


    This challenge is open to the general public. Public, private, and academic organizations.

    How can Blockchain Technology Be Used to Help Prevent Child Trafficking in Moldova?

    The task is to propose a detailed project concept and functional design of the solution that would encompass the following sub-components:


    Undocumented children and minors can become an easy prey for human traffickers, who often use fake identification (ID) documents to transport them across borders. Once trafficked, these children and minors are sold to sex brothels, caught in modern slavery rings, and even used for the illegal human organ trade. Digital identity on the blockchain may offer a significantly higher chance of catching traffickers and securing data on an immutable ledger, further making any such trafficking attempts more traceable and preventable.
    However, concerns over the privacy of the identity data stored should be identified and clarified, along with proposed ways of addressing them. The proposed solution should allow establishing a unique, secure, digital identity for children and minors aged 0-14 y/o (pilot size: approx. 350,000 children, with modalities of linking children’s personal identity to that of their family members.


    Setting up a solution that would allow securing identity data on the blockchain, making an immutable record of the actual, or attempted exit with a minor without parents’ permission outside the borders of Moldova.

    The integrated ID system may cover the total population (size: 3,500,000 people) or a subset of it, and the choice between these two options should be explained and justified. Issues such as “the right to be forgotten” and the self-sovereign control of data should also be addressed in the proposed solution.


    Potential or actual victims of trafficking are often times isolated and lack support and help in critical circumstances. However, the traditional communication tools, such as direct contact with a social worker, for example, may not function in this context. Setting up a solution that would allow the use of artificial intelligence (AI) tools, for instance, could help recognize and detect patterns of behavior and automate communication with the victims.


    Your submission must include the following materials:

    1. Detailed concept design and documentation describing the functionalities and explanation of the approach taken to solve the Challenge and the proposed solution.

    2. Demonstration systems, prototypes, or videos illustrating the functionality described. (you must provide a link to the source code of any demonstration material you submit).

    If you decide to submit a solution, you will do so by providing Internet links where your documentation, software, demos and any material will be stored, which shall be marked and accompanied by creative common and recognized open source software licenses, and shall be visible and accessible to the general public. You will be asked to accept the terms and conditions below:
