Demonstration for Channel and Private Data in Hyperledger Fabric

Overview

This repository is the demonstration setup showing Channel and Private Data in Hyperledger Fabric. Refer to this article for detail.

Note

For demo purpose both the crypto-config and channel-artifacts are pre-generated. The files are generated with Release 1.4.2. In case you are using Release 1.4.3, you have to re-generate the channel-artifacts. After you git clone the repository, you can generate the new set of channel artifacts.

cd fabric-samples
git clone https://github.com/kctam/dataprivacy.git
cd dataprivacy/network
