MetaLocker

MetaLocker is a data distribution framework that enables secure and privacy preserving data exchange between participants of a knowledge network.

It allows users to exchange data with other users in a secure and transparent way while retaining control of their data. MetaLocker protocol is agnostic of communication and storage media, be it a file system, a network storage service or a distributed ledger.

MetaLocker is an open-source version of ChainLocker, a product developed by Piprate, complete with enterprise features like Hyperledger Fabric connector, AWS integration and more.
