Re: How to set regulator or auditor in private data collection


David Enyeart
 

A regulator or auditor would be modeled as any other organization.

Example: Channel includes four organizations: 'Org1', 'Org2', 'Org3', 'regulator'.

Create Org1Collection that includes (Org1, regulator) in the private data distribution "policy" and "endorsementPolicy".
Create Org2Collection that includes (Org2, regulator) in the private data distribution "policy" and "endorsementPolcy".
Create Org3Collection that includes (Org3, regulator) in the private data distribution "policy" and "endorsementPolcy".

Org1Collection would have properties as:

"policy": "OR('Org1.peer', 'regulator.peer')"
"endorsementPolicy": {
"signaturePolicy": "AND('Org1.peer', 'regulator.peer')"
},

This implies that any private data written to Org1Collection requires endorsement from a 'Org1' peer AND a 'regulator' peer. And the private data will get distributed to any peer belonging to 'Org1' OR 'regulator'.

See collection definition doc at https://hyperledger-fabric.readthedocs.io/en/release-2.0/private-data-arch.html#private-data-collection-definition.

Hi All,
The fabric doc said: “Fabric v2.0 also enables new patterns for working with and sharing private data, without the requirement of creating private data collections for all combinations of channel members that may want to transact. Specifically, instead of sharing private data within a collection of multiple members, you may want to share private data across collections, where each collection may include a single organization, or perhaps a single organization along with a regulator or auditor”.

I wonder how to set regulator or auditor along with a single organization when using private data in Fabric 2.0?
Is there any sample to tell how to do this?
