Why Choose Quorum Blockchain?

There are various aspects to data privacy within a blockchain network. Take a look at the below points to find out how to ensure data privacy within a Hyperldger Fabric blockchain network:

1. You can segregate your network into channels, where each channel represents a subset of participants authorized to see the data for the chaincodes deployed to that channel.
2. You can use private data to keep ledger data private from other organizations on the channel. A private data collection allows a defined subset of organizations on a channel to endorse, commit, or query private data without creating a separate channel. Other participants on the channel receive only a hash of the data.
3. As an alternative to Fabric hashing the data using private data, the client application can hash or encrypt the data before calling chaincode. If you hash the data, you will need to provide a means to share the source data. If you encrypt the data, you will need to provide a means to share the decryption keys.
4. You can restrict data access to certain organizational roles by building access control into the chaincode logic.
5. You can encrypt ledger data at rest via file system encryption on the peer, and data-in-transit is encrypted via TLS.

Depending upon the seniority of the blockchain development team, the number of resources required, types of resources required, and the costs involved in a blockchain application development vary.
