Need specific chaincode for PDC(Private Data Collection)?

Question

I am trying using PDC on hyperledger fabric for testing.

So then, I heard that PDC needs specific chaincode for itself, not exactly.

For using PDC, do it need something special chaincode only for PDC??

Answer 1

First of all, you need to make colletions_config.yaml file.

When you instantiate the chaincode, specify the flag --collections-config [path]

Chaincode Functions:

• stub.GetPrivateData()
• stub.PutPrivateData()
