Blockchain Hyperledger management for system admins

In this course you learn how to setup Hyperledger network and manage it. This course will prepare you for the Certified Hyperledger Fabric Administrator certification exam.

Coding Bootcamps School is an authorized training provider for The Linux Foundation.

Blockchain technology is disrupting many traditional businesses. Blockchain technology has moved beyond the hype and there exist hundreds of networks in production today. Many of the production blockchain solutions in production today are built with Hyperledger Fabric.

Hyperledger Fabric is an enterprise-grade, distributed ledger platform that offers modularity and versatility for a broad set of industry use cases. The modular architecture for Hyperledger Fabric accommodates the diversity of enterprise use cases through plug and play components, such as consensus, privacy and membership services. Hyperledger comes with many projects and tools. The most popular project is Hyperledger Fabric that uses chaincode for writing and deploying Blockchain Smart Contracts.  

Behind every great open source technology, sits a strong community. The Hyperledger Fabric community has continuously improved the security, usability, robustness, performance and feature set — all qualities that are of critical importance to enterprise users. To date, there are no other distributed ledger technology frameworks that enjoy the breadth of adoption by Cloud Service Providers such as AWS, Azure, IBM, Google, and Oracle.

3- Hyperledger Blockchain Ecosystem

In this section, we review Hyperledger ecosystem and projects for building blockchain applications. This section describes the organization of the Hyperledger Foundation, its history, and leadership. In addition, we provide an introduction to the open source projects in the portfolio.

• An introduction to the Hyperledger family begins with a description of the foundation, organization, and leadership. We then describe each project in the foundation which are divided into groups: Distributed Ledgers, Libraries, Tools, and Domain-Specific projects..
• The framework projects describe: Besu, Burrow, Fabric, Indy, IROHA, and Sawtooth. 
• The Libraries projects describe: Aries, Quilt, Transact, and Ursa
• The Tools projects describe: Avalon, Caliper, Cello, and Explorer
• The Domain-Specific projects describe: Grid
• Building the Hyperledger framework layers describes the structure of the projects and how they are intended to complement, leverage, and work together.
• The Hyperledger design philosophy at a glance is a brief discussion on the general design approach and methodology used to select and develop projects within the ecosystem.
• Framework architecture overview describes at a high-level the layers and components required for implementing blockchain technology.
• The consensus layer describes and covers the various algorithms used to implement consensus within a blockchain. Fabric and Sawtooth will be used as examples. 
• Smart contracts are programs used to execute the specific application logic for a blockchain. We will describe the different designs and methods for implementing smart contracts in Hyperledger comparing Fabric with Sawtooth.
• Databases are used for the immutable ledger and for storing state data. We will describe the different options available for Fabric.
• Peer networking is a primary component of any blockchain, so we provide a brief description of the network architecture used to create a Fabric blockchain.
• Quiz

4- Components and Architecture of Hyperledger Fabric

In this section, we will review the architecture of Hyperledger Fabric as well as installation requirements for building blockchain applications using Hyperledger Fabric. 

• Hyperledger Architecture
• Peer --we describe the peer which is a node and can be a virtual machine or physical machine. It performs the processing. 
• Ordering service -- is described which is responsible for ensuring the timestamped transactions are in chronological order. Nodes use this service prior to committing transactions.
• Fabric CA (Credential Authority) is responsible for validating and maintaining the certificates used for cryptography functions. We will provide a description of this component.
• Fabric ledger is the database for storing the transaction results and is divided into two components which we will describe: the immutable ledger and world state. 
• Channel is a primary data communications design for connection nodes into secure networks capable of executing transactions for smart contracts and protecting data. We will describe how channels operate and their design.
• Organization is the basic entity within a Fabric network and is used for creating identities for executing various functions including transactions, security, smart contracts, and more. We will describe the organization and how they are used.
• Endorsement policy is a Fabric design pattern for securely executing transactions. It is a function carried out by nodes. We will describe this function and the workflow it operated under. 
• Membership services provider (MSP) is the user store for maintaining and granting rights to identites to carry out functions and transactions in a Fabric blockchain. We will describe the MSP and how it is utilized in Fabric.
• Fabric Installation Requirements -- Fabric has several requirements that must be implemented in order to establish a proper functioning Fabric blockchain. We will go over what these are and describe each one. 
• Quiz

5- Application Lifecycle Management

In this section, we review how to setup and manage chaincode and set its data sharing policies. Chaincode represents a smart contract and can be developed in several different languages. We will describe how you create, deploy, and manage chaincode.

• Install, and Instantiate chaincode package -- we will describe how chaincode is created and loaded onto a node for processing the transaction logic implemented in chaincode. 
• Configure endorsement policy -- before chaincode can execute it must pass specific user defined rules known as endorsement policy. We will describe the available policies and how to configure them within a Fabric blockchain.
• Define collection policy for private data -- in Fabric channels consist of several nodes that execute chaincode, but depending on the privacy policy not all nodes may be allowed to see all of the data, so Fabric has policies for protecting data so only allowed nodes can see it and operate on it. We will go over the process for defining, configuring, and processing protected data.
• Modify or upgrade chaincode -- Fabric has the ability to keep chaincode current to meet changing application requirements. We will cover how to upgrade chaincode to keep it current.
• Quiz
