Fabric

In order to understand various projects under incubation in Hyperledger project, it is important to understand the foundations of Hyperledger first. A few terminologies that are specific to Hyperledger needs some clarification before readers are introduced to 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 modular approach towards building blockchain networks. In this case the blockchain network can have multiple pluggable modules to perform various function on the network. For example, consensus algorithms can be a pluggable module in a blockchain network where, depending on the requirements of the network, an appropriate consensus algorithm can be chosen and plugged...
