Elizabeth Nyamwange hopes to make her gender-equality-meets-blockchain-technology dream a reality.

When HP, Inc. put out a worldwide call last fall for girls ages 13 to 18 to submit innovative ideas about how to address an environmental or social issue in their community, more than 800 applications poured in from 148 countries., HP awarded the grand prize to the development and implementation of: Etana, a low-cost, solar-powered fingerprint scanner that provides women in developing nations with a digital proof of identity even if they don’t have access to the Internet or electricity.

When she researched the topic, she learned there were other tech companies focused on solving these identity issues, but their solutions required users to have access to WiFi. She knew this was an obstacle that needed a workaround because that technology isn’t readily available everywhere. So, she wrote the code for Etana, which converts a physical fingerprint into a mathematical algorithm that uploads to a private blockchain server where it is stored and used as identification.
