What is Hyperledger Fabric?

Before we compare both Hyperledger projects, we’ll briefly introduce the two projects and their characteristics. Let’s start with Hyperledger Fabric. Hyperledger Fabric is one of the prominent open-source distributed ledger technology projects under Hyperledger. It’s an enterprise-grade blockchain platform that offers protocols, ledgers, smart contracts, standards and many more key blockchain elements.

Anyhow, Hyperledger Fabric is a permissioned blockchain, and it does not support any permissionless iterations. Therefore, it offers an authentication method to authenticate users before they can get access to the network. This is one of the safest and secure blockchain platform suited for enterprise companies.

Hyperledger Fabric 2.0 is the latest version of this platform, and it does offer certain extra functionalities like chaincode lifecycle management, external chaincode launcher, improved performance and so on.

Basic Characteristics of Hyperledger Fabric

There are some certain basic characteristics of the Hyperledger Fabric project. Let’s understand what functionalities they offer.

Open-Source Code

This platform is fully open-source. Therefore, anyone can get access to the source codes and use them in any way they want. You won’t have to buy the platform from them or pay any fees to buy a license. More so, they don’t have any issues regarding vendor lock-ins.

Wide-Ranging Industrial Usage

If you check out any Hyperledger Fabric tutorial, you will notice that the internal architecture and features go hand in hand with many industries. More so, there are already many companies using Fabric for their blockchain solution, and these solutions are performing extremely well.

High-Quality Infrastructure

All of the source code and the infrastructure is carefully designed to make it perfect. In reality, the developers behind Fabric make sure to quality check every single programming before they finalize it. So, you can always expect the best output from them.

Higher Efficiency

Hyperledger Fabric offers a highly efficient output compared to other enterprise blockchain platforms at the moment. As it can separate transactions from other functions within the network and streamline the verification process much faster.

Modular Design

Hyperledger Fabric offers a modular structure. Therefore, you can design any independent module and just add it to the network. In reality, this feature adds customizability to the whole platform. Anyhow, let’s check out Aries in this Hyperledger Aries vs Fabric guide right now.

What is Hyperledger Aries?

Hyperledger Aries recently became active, and it’s now ready to use according to the Hyperledger community. It’s actually a library suite that offers an infrastructure for peer-to-peer network and blockchain-rooted interactions within platforms. However, it’s neither an application nor a blockchain platform. More so, Hyperledger Aries uses the cryptographic support from Ursa to offer better key management and secret management systems.

What Purpose Does Hyperledger Aries Serve?

Aries comes from both Hyperledger Indy and Ursa. More so, from Ursa, Aries gets the cryptographic functionality, and from Indy, it gets an implementation of the resolver. Therefore, the main purpose of Aries is to alter the client layer within the Hyperledger Indy infrastructure to make it suitable for interacting with other platforms. Aries actually implements a standard for interoperability in this case. Anyhow, let’s check out the key characteristics of Aries in this Hyperledger Aries vs Fabric guide.

Key Characteristics of Aries

  • Blockchain interface layer or resolver for reading, creating and signing transactions.
  • Cryptographic storage for verifiable credentials, cryptographic secrets, and other information for clients.
  • Peer-to-peer encrypted messaging unit to support off-ledger interactions within platforms.
  • ZKP-based W3C verifiable credentials mainly come from Ursa.
  • Higher-level protocol series that ensures deployment and independent implementation of Aries agents.
  • Production ready framework for Aries deployments and Hyperledger use cases. Every framework is suited for a specific use case.
  • Test harness for agents to ensure proper interoperability testing before launching.

Hyperledger Aries vs Fabric: How Are They Different?

The comparison of Hyperledger Aries vs Fabric is rather a difficult approach as both projects are quite different from each other. We’ve compiled some of the crucial differences you need to know before you start using these projects for your blockchain development.

Project Type

The very first difference between Hyperledger Aries and Fabric is the types of Hyperledger project type. Fabric is actually a distributed ledger technology, a fully functioning blockchain platform with nodes, transaction protocols, consensus, smart contracts, etc. Therefore, companies can use this platform to develop other projects.

On the other hand, Aries is a library suite or toolkit that offers an array of protocols and modules for blockchain platforms. Thus, Hyperledger Aries is not a blockchain platform in any way. You can use Aries to integrate certain functionalities in your blockchain projects, but you can’t use Aries as your blockchain project base.

Blockchain Agnostic

Blockchain agnostic actually means that a company can operate a solution from multiple blockchain platforms. At present, most of the applications only use a single blockchain platform that offers specific use cases and functions. Therefore, there is no blockchain application that can communicate with other blockchain platforms seamlessly.

In this case, Hyperledger Fabric does not offer any solutions. This means that Fabric is not blockchain agnostic. The Fabric still does not offer any protocols regarding this issue in their latest version. On the other hand, Aries is fully blockchain agnostic. It means that any kind of blockchain platform can use this tool to connect to other blockchain platforms.

Interoperability

Interoperability is one of the major issues of any blockchain platform. Blockchain platforms can’t still offer interoperability with other solutions and this makes it very limiting. At present, Hyperledger Fabric does not offer any blockchain interoperability protocols that can communicate with other networks.

On the other hand, Hyperledger Aries offers a feature called DIDcommunications that can seamlessly interact and communicate or even offer messing services with other blockchain platforms. Anyhow, let’s look at the next difference in this Hyperledger Aries vs Fabric guide.

Zero-Knowledge Proof

Hyperledger Aries and Fabric both have ZKP protocols attached to them. But the usage of Zero Knowledge Proof is different in both projects. In Fabric, you can use ZKP for identity Mixer for the anonymous client authentication process. You can also use Zero-Knowledge Asset Transfer for preserving privacy in case of assets exchange.

On the other hand, In Hyperledger Aries, you will get ZKP-based W3C verifiable credentials. It uses the ZKP primitive from Hyperledger Ursa at the moment. So, both projects use ZKP, but they are use it for different functionalities.

Consensus

As Hyperledger Fabric is a blockchain platform, it comes with various consensus algorithms that you can use for your blockchain implementations. At present, Fabric will offer Solo, Kafka and Raft consensus methods to verify transactions. On the other hand, Aries is not a blockchain platform but a library suite. However, in the library suite, you will not get any new consensus protocol suited for blockchain platforms. We don’t know if Hyperledger is planning to include any protocols in the future that may offer consensus methods as of now.

Use Cases

Hyperledger Fabric is a fully functioning platform; thus, it’s developed to be used in various industries. Many companies using blockchain technology are already using Fabric for various use cases. Furthermore, you can use this platform for supply chain, trade finance, real estate, insurance and so on.

But Aries is developed focusing on digital identity. Therefore, it’s more suited for any identity management solutions. As of now, it supports Hyperledger Indy, so you can couple Indy and Aries to develop an interoperable identity management system.

Here’s a guide to Hyperledger Fabric use cases and case studies that you can check out to learn more about the platform.
