Blockchain, dati biometrici, rifugiati e servizi finanziari. Cosa mai può andare storto? <https://techcrunch.com/2018/11/29/gravity-earth/> There’s considerable interest in the way blockchain technology could be used to manage personal data — so-called “self-sovereign ID” — but, to date, there are precious few examples of exactly how it might work. At TechCrunch Disrupt Berlin on the Startup Battlefield stage, Gravity Earth gave insight into how blockchain can be used to help refugees gain access to financial services and other resources to raise their standards of living. The Nairobi-based startup was founded by Johannes Ebert and Paul Langlois-Meurinne. It has developed a platform that allows a person’s digital data to be stored securely on its decentralized platform. That’s a lot of technical terminology, and in practice it translates to helping digitize data that can be used by NGOs who are working at refugee camps with some 80,000 people. In Gravity Earth’s case, it is close to its first deployment at a refugee camp in Kakuma, Kenya. The rollout will see Gravity Earth’s solution used to track daily attendance at three schools in the camp, and student’s academic performance. That’ll be based on biometric data, with teachers able to upload performance and test data via a web app. [...]
