To understand various projects that are under development in the Hyperledger project, it is essential to understand the foundations of Hyperledger first. A few terminologies that are specific to Hyperledger need some clarification before readers are introduced to the more in-depth material.
First, there is the concept of fabric. Fabric can be defined as a collection of components providing a foundation layer that can be used to deliver a blockchain network. There are various types and capabilities of a fabric network, but all fabrics share common attributes such as immutability and are consensus-driven. Some fabrics can provide a modular approach towards building blockchain networks. In this case, the blockchain network can have multiple pluggable modules to perform a various function on the network.
For example, consensus algorithms can be a pluggable module in a blockchain...
