ABOUT HYPERLADGER FABRIC IN BLOCKCHAIN CERTIFICATION
What is the Hyperledger Fabric in Blockchain?
Hyperledger Fabric is an open-source distributed ledger technology with a modular design that provides high levels of secrecy, flexibility, robustness, and scalability. This allows fabric-based solutions to be tailored to any business. The Linux Foundation manages this private and secret blockchain architecture.
Hyperledger Fabric in the Workplace
A product’s supply chain might be global or localised, and it is made up of a variety of suppliers, producers, and retailers. In order to enhance supply chain transaction procedures, Hyperledger Fabric networks may help by boosting transaction clarity and traceability. Data from earlier transactions may be seen by businesses that have been authenticated to access the ledger on a Fabric network. As a result, the transactions are more transparent and less vulnerable to fraud. Keeping the ledger up to date with manufacturing and shipment statistics in real time is possible. As a result of this, we can monitor the product’s condition in a more efficient manner.
Importers, exporters, banks, and brokers are just a few of the various entities and individuals needed to do business and move assets. They’re all on the same team. Even in this digital age, there is still a significant amount of paper-based labour in this industry. Hyperledger, on the other hand, enables them to do business and collaborate without the need of paper. As with a document signed by a reputable authority, the Hyperledger fabric may provide the same level of confidence as that document. The system’s performance is also improved as a result of this.
The ability to dematerialize assets on the blockchain network is another advantage of Hyperledger fabric. Investors or traders will be able to trade at any moment because of this.
There is a huge amount of money spent on insurance fraud and false claims. The Insurance business can access transaction data stored in the ledger thanks to Hyperledger fabric. The chain code in Hyperledger Fabric helps speed up claim processing and automate payment in Hyperledger Fabric. Multi-party subrogation cases might also benefit from this procedure. Where the insurance company may be automatically reimbursed by the at-fault party. This private blockchain will make the process of verifying an individual’s identification (KYC) a breeze.

CHFD is for Node.js developers who wish to demonstrate their ability to package and deploy Fabric apps and smart contracts, as well as handle the end-to-end Fabric application lifecycle and smart contract administration.
A CHFD should be able to demonstrate that they understand how to use the newest Fabric programming model to create and manage client apps and smart contracts.
Package and deploy Fabric apps and smart contracts, conduct end-to-end Fabric application life-cycle and smart contract administration – programme in Node.js
This course’s lab exercises are designed to run on either native hardware or a virtual machine (VM) running under a hypervisor, such as those from the KVM, VMWare, or Virtual Box families. The course includes detailed guidance for setting up your lab environment.
WHAT YOU WILL LEARN
- how to implement and test a chaincode in Golang for any use case,
- how to manage the chaincode life cycle,
- how to create Node.js client applications that interact with Hyperledger Fabric networks,
- how to control access to information based on a user identity,
- how to set up and use private data collections, and much more.
ABOUT CERTIFICATION EXAM
This exam is a proctored, online performance-based certification that consists of a collection of performance-based tasks (problems) that must be performed using a Web IDE and the command line.
THE LINUX FOUNDATION CERTIFICATION VERIFICATION TOOL
Individuals who achieve Linux certification represent the best talent available and have the skills required to perform challenging real-world tasks under time constraints. This verification tool allows you to confirm the validity of the certification. Credentials can also be verified by potential employers to confirm competencies gained.
Advantages of Hyperledger Fabric
It is Open Source
Blockchain framework Hyperledger fabric is managed by the Linux Foundation and is open-source. It has a thriving developer community. The code is meant to be open to the general public. Everybody in the community may access, change, and share the source code as they see appropriate. People from all around the globe are welcome to contribute to the code.
Confidential and safe
There are two types of blockchains, public and private. In a public blockchain, every node in the network receives a copy of the whole ledger. As a result, protecting one’s privacy has never been more important. Another issue is that there are no confirmed or verified identities for all of the participants. As a public blockchain, anybody may participate. Hyperledger fabric, on the other hand, authenticates the identities of all participants. The ledger is only accessible to members who have been authenticated. When it comes to banking, insurance, and other industries where consumer data must be kept confidential, this advantage is especially beneficial.
Chain code function
A container technology known as chain code is used to hold smart contracts that describe the system’s business rules. In addition, it’s built to handle a wide range of pluggable elements and to handle the complexity of the economy. Certain sorts of transactions, such as the transfer of ownership of an asset, benefit from this.
Control of Access
There is a virtualized blockchain platform on top of physical network in Hyperledger fabric. It has its own set of regulations for accessing the site. An extra degree of security is provided by the use of its own transaction ordering mechanism. When members wish to keep their data secret, this is a great option. So that it can only be seen by those who are directly involved. As an illustration, consider the situation in which two rivals share a network. Besides private data collecting and access, the fabric also provides a way for a competitor to keep its data secret from the other competition.
Finally, the Hyperledger fabric has a quicker transaction speed since it does not need to be validated by other networks. This results in greater performance.
According to Blockchain Council, the average base salary for a Blockchain Developer in the U.S. was $136,000 per year.
