BeD: A Blockchain-enabled Data LakeAs a research intern, I am working on developing a blockchain-enabled data lake to enable secure data sharing between stakeholders. The data lake comprises databases from different organizations that need to share data confidentially. The goal is to build a federated data sharing system using blockchain that maintains trust by ensuring shared data is only used for agreed purposes in a transparent and verifiable way. Through this project I am gaining experience with blockchain, cryptography, and access control to enable confidential data sharing.
