1. Introduction

In this tutorial, we refer to a sample configtx.yaml. This sample file is a long one, so I don’t embed into the blog post. I suggest that you could quickly take a look, then continue, and read some related parts of the sample configtx.yaml whenever there is a need to refer to it. Also I assume that you have had a certain level of understanding for Hyperledger Fabric.

In the sample configtx.yaml, there are two types of policy:

The First Type — Signature

the first type of policy

The Second Type — ImplicitMeta

the second type of policy

Signature type policy is easy, while ImplicitMeta type policy is abstract. This short tutorial is to explain how to interpret ImplicitMeta type policy.
