Learn more about Hyperledger Fabric, its benefits, how it works, and how to get started

Hyperledger Fabric is an open-source blockchain platform that is designed for enterprise use cases. It is based on a distributed ledger technology and allows businesses to build and deploy their own blockchain networks. These networks, also known as fabric networks, consist of various network participants, such as peer nodes, which are responsible for validating and committing transactions to the ledger.

One of the key features of Hyperledger Fabric is its support for smart contracts, which are self-executing contracts with the terms of the agreement written into code. These contracts can be used to automate various business processes and help ensure that transactions are carried out in a transparent and trustworthy manner.

In a supply chain network Project, for example, Hyperledger Fabric could be used to track the movement of goods from manufacturer to consumer, with each participant in the network adding transaction data to the ledger as the goods are shipped from one location to the next. This data could include information about the goods, such as their type, quantity, and quality, as well as details about the parties involved in the transaction, such as the sender, recipient, and any intermediaries.

To initiate a transaction on a Hyperledger Fabric network, a network participant would create a transaction proposal and submit it to the network for endorsement. If the proposal is endorsed by the required number of peer nodes, it can be added to the ledger and becomes a permanent part of the network’s history. In this way, Hyperledger Fabric enables businesses to securely and transparently track the movement of goods and other assets through the supply chain.

What is Hyperledger Fabric Mechanism?

Hyperledger Fabric is a permissioned blockchain platform that allows organizations to build and run applications on a private, shared ledger. At a high level, Fabric works by allowing a client application to submit a transaction proposal to an endorser peer, which then executes a piece of chaincode (i.e., smart contract logic) to validate the transaction. If the transaction is valid, the endorser peer will then submit the transaction, along with an endorsement, to a Fabric Certificate Authority (FCA). The FCA checks the endorsement against the organization’s policies, and if the transaction is approved, it is added to the shared ledger.

Fabric also includes a system for managing digital assets, which are represented as chaincode and stored on the shared ledger. In this way, Fabric provides a secure and transparent way for organizations to track and manage their digital assets on a private, permissioned blockchain.

Benefits of Hyperledger Fabric

There are several benefits to using Hyperledger Fabric as a blockchain platform:

  1. Security: Fabric uses a permissioned model, which means that only authorized parties are allowed to access the network and participate in the consensus process. This makes it more secure than public blockchains, which are open to anyone.
  2. Scalability: Fabric uses a modular design, which allows it to scale horizontally by adding more endorsement and commit peers to the network. This makes it more suitable for large-scale, enterprise-grade applications.
  3. Flexibility: Fabric allows for the creation of custom consensus algorithms, which means that organizations can tailor the consensus process to fit their specific needs. Additionally, Fabric supports a wide range of programming languages, making it easy to build and deploy applications.
  4. Interoperability: Fabric includes support for pluggable components, such as identity management systems and consensus algorithms, which allows it to easily integrate with other systems and technologies.

Overall, the benefits of Hyperledger Fabric make it a powerful choice for organizations looking to build and deploy secure, scalable, and flexible blockchain applications.

How does Hyperledger Fabric Work Programmically?

At a high levels, the Hyperledger Fabric system is a private blockchain platform that allows organizations to build and run applications on a shared ledger. The Fabric system utilizes a consensus algorithm to ensure that transactions are executed in a secure and transparent manner. When a client application submits a transaction request, it is first endorsed by one or more endorser peers, who execute a piece of chain code (i.e., smart contract logic) to validate the transaction execution. If the transaction is valid, the endorser peers will submit the transaction, along with an endorsement, to the ordering service. The ordering service then orders the transactions into a block and broadcasts the block to the commit peers, who use the endorsement policy to determine whether to commit the transaction to the ledger. Once a transaction is committed to the ledger, it becomes a part of the ledger state, which is stored in key-value pairs. The Fabric system is written in Node js and is designed to be highly modular and flexible, allowing for the integration of various pluggable components such as identity management systems and consensus algorithms. In contrast to a public blockchain, which is open to anyone, the Fabric system is a permissioned blockchain, which means that only authorized parties are allowed to access the network and participate in the consensus process. This high degree of security makes the Fabric system well-suited for use in enterprise-grade applications.

Hyperledger Fabric Transaction Flow

The transaction flow in Hyperledger Fabric follows a specific process to ensure the security and integrity of the shared ledger. When a client application wants to submit a transaction to the Fabric network, it sends a transaction proposal to an endorser peer. The endorser peer then executes the chaincode (i.e., smart contract logic) associated with the transaction to validate it. If the transaction is deemed valid, the endorser peer will sign the transaction and send it back to the client application with an endorsement. The client application will then send the endorsed transaction to the ordering service, which orders the transactions into a block and broadcasts the block to the commit peers. The commit peers will then check the endorsement policy to determine whether to commit the transaction to the ledger. If the endorsement policy is satisfied, the commit peers will add the transaction to the shared ledger and replicate it to all other commit peers on the network. This process ensures that all transactions on the Fabric network are validated and securely recorded on the shared ledger.

Hyperledger Fabric vs. Hyperledger Sawtooth

Hyperledger Fabric and Hyperledger Sawtooth are both open-source, modular blockchain platforms developed under the Hyperledger umbrella project. While both platforms are designed to support the development and deployment of enterprise-grade blockchain applications, there are several key differences between them.

One of the main differences between Fabric and Sawtooth is the way in which they handle consensus. Fabric uses a pluggable consensus model, which allows organizations to choose the consensus algorithm that best fits their needs. Sawtooth, on the other hand, uses a novel consensus algorithm called Proof of Elapsed Time (PoET), which uses a trusted execution environment (TEE) to ensure that the consensus process is secure and fair.

Another difference between the two platforms is the way in which they handle transactions. Fabric uses a modular design, with separate roles for endorser peers and commit peers, while Sawtooth uses a more integrated approach, with each validator on the network responsible for both transaction execution and ledger updates.

Overall, the choice between Fabric and Sawtooth will depend on the specific needs and requirements of the organization. Fabric may be a better fit for organizations that require a high degree of flexibility and customization, while Sawtooth may be a better fit for organizations that prioritize security and scalability.
