How to ensure data privacy in Hyperledger Fabric

Question

I am new to Hyperledger Fabric and trying to build an application. I wanted to ask, how is data privacy handles in Hyperledger Fabric?

Answer 1

There are different ways data privacy in Hyperledger Fabric.

• You can segregate your network into channels. Each of these channels represents a subset of participants that are authorized to see the data for the chaincodes that are deployed to that channel. Hence data visibility is limited
• You can use private-data to keep ledger data private from other organizations on the channel.
• You can restrict data access to certain roles in your organization, by building access control into the chaincode logic.
