If you are considering starting your career as a Hyperledger Developer or thinking of transitioning into it from another background, then the information provided in his article is definitely for you. Let’s dive right in!

What is Hyperledger Fabric?

The Linux Foundation is responsible for creating the Hyperledger project in 2015 to promote cross-industry blockchain technologies. Linux Foundation is trying to encourage a more associative approach by developing blockchain technologies with a community approach.
Hyperledger Fabric is a platform designed for distributed ledger solutions.

Some of the unique features it offers are scalability, resilience, flexibility, and a high degree of confidentiality. It is designed in a way that it assists the pluggable implementations of various components. Moreover, this platform also makes room for all the complexities and intricacies that exist in an economic ecosystem.
Uniqueness of Hyperledger Fabric

Hyperledger Fabric is different from other blockchain systems because it is private and permissioned. The members are enrolled through a trusted Membership ...
... Service Provider (MSP). This is unlike an open, permissionless system because in that unknown identities can participate as long as the ‘proof of work’ protocol is used to validate the transaction and secure the network.

In Hyperledger Fabric, the ledger data can be stored in multiple formats. There’s the ease of movement because consensus mechanisms can be swapped in or out. Moreover, there’s scope for different MSP’s to be supported.

The creation of channels is another feature of Hyperledger Fabric. This allows a group of participants to create a separate ledger of transactions. For example, on a given network, there could be some participants who are competitors. If they do not want other participants to have knowledge of a transaction that has been made, then a separate channel is possible for the two participants involved in that particular transaction

Essential Components of Hyperledger Fabric
You should have a sound knowledge of all the elements within the Hyperledger Fabric. This will make your case stronger as you apply for a Hyperledger Developer job.

• Shared Ledger

The shared ledger of Hyperledger Fabric has a subsystem that is comprised of two components. These are the world state and the transaction log. State component refers to the state of the ledger at any given point in time. Basically, it is the database of the ledger.
On the other hand, the transaction log refers to all the recorded transactions that have resulted in the current value of the world state. Technically it is an updated history of the world state. So the Hyperledger Fabric ledger is a combination of the world state database and the transaction log history.

The ledger has a replaceable data store for the world state. It is a LevelDB key-value store database. Every participant has a copy of this ledger, depending on which Hyperledger Fabric network they belong to.

• Smart Contracts

The smart contracts in Hyperledger Fabric are written in chaincode. It is invoked by an external application when that particular application needs to interact with the ledger. Usually, chaincode only interacts with the database component of the ledger and not the transaction log.

Chaincode can be executed in different programming languages i.e., Go and Node.

• Privacy

Hyperledger Fabric supports both types of networks. Ones that are open as well as those which have privacy as a critical operational requirement. It all depends on the needs of the network. For example, in a Business-to-Business (B2B) network, there will be extreme caution in managing sensitive information, whereas privacy might not be a top priority for others.

• Consensus

All the transactions on a ledger must be written in the order in which they occur, even if they’re between different sets of participants within a network. This fool-proof method for avoiding bad transactions is achieved with different mechanisms.

One of them, for example, is Practical Byzantine Fault Tolerance or more commonly known as PBFT. This mechanism allows the file replicas to communicate with each other so that each copy is consistent. This consistency is maintained even if there is any attempt to corrupt the ledger. This is different from what happens in Bitcoin. The ordering in Bitcoin occurs through a process called mining where competing computers race to solve a cryptographic puzzle that defines the order that all methods subsequently build upon.

Hyperledger Fabric is designed in a way that it has the freedom to let network starters choose the consensus mechanism that best suits the relations of participants. Similar to options of privacy, consensus also can be highly structured or more peer-to-peer, etc. Some of the common ones are Kafka, Raft, and SOLO.

Job Options

Learning all about Hyperledger Fabric can open multiple windows of career prospects for you. Some of the top jobs trending in the United States of America are that of a Hyperledger Developer, Blockchain Engineer, Blockchain Solutions Architect, Java Developer, etc.

However, as with all jobs, it’s essential to have the right set of qualifications and experience to land the position of your choice. A background in computer science, engineering, programming, statistics, or any other relevant field is preferred. You could do a graduate or a postgraduate course for the same. However, if you’re looking for a short term online course on Hyperledger, you can sign up for the Certified Hyperledger Expert. And if you’re looking to become a developer, then Certified Hyperledger Developer would be more suited to your needs.

Salary with Hyperledger Qualifications

As a qualified Hyperledger developer with good work experience, your salary package can fall anywhere between $122–179k. But if you’re just starting out, it might vary between $80–110k since it’s just stepping into the field.

Conclusion

Hyperledger solutions are not limited to any particular field or industry. Hence there is a constantly growing need for Hyperledger developers. The best way to move ahead is by learning and doing. Connect with people who are in the same field and approach them with an open mind. It’s important to take part in events, meetups, webinars, and seminars, etc. to stay connected with the fraternity.
