Right now a colleague of mine are working on a project called TallyLab. It's a "data diary" based on IPFS and OrbitDB. By utilizing those technologies we hope to create a distributed, decentralized, end-to-end encrypted, peer-to-peer system that gives people full control over their data. We believe it will be the first of many "GDPR-first" or "HIPAA-first" apps.
