Hyperledger Tutorial: What is Hyperledger?
Linux Foundation first came up with the concept of Hyperledger. It’s an umbrella project and also open-source. More so, it comes with loads of free tools and frameworks for you to try out. Basically, these tools, libraries are made for enterprises and developers to help them build a new blockchain solution based on that.
Also, you get access to a very large community that will help you out in terms of developing new revolutionary technologies. Anyhow, Hyperledger came into existence back in 2015, and it came a long way with 16 new projects under it.
However, only 7 projects are active at present. If you want to learn about these, you’d have to use the Hyperledger tutorial. Let’s check out the fundamentals of this platform in this Hyperledger tutorial guide.

Why Did the Linux Foundation Create This Project?
You must be wondering why did Linux foundation really come up with the concept; what was the need? Well, blockchain technology did come in 2008 from Bitcoin. However, it didn’t gain any traction until later.
Even though it was only a cryptocurrency-based technology back then, soon, many were more than interested in the underlying technology – blockchain.
However, there wasn’t any workable integration of the technology into any existing solution so far. Thus, enterprises started to wonder how they could achieve faster innovation.
So, they started to work together and started to work on projects, and this way, they could save a lot of time and come up with a workable solution much faster.
In the Hyperledger developer tutorial, you’ll know how the Linux foundation took the step and formed the project with other companies to streamline blockchain’s popularity and change the world. Thus, the companies started to implement blockchain solutions that other businesses could use and accept the model for business.
And why wouldn’t they? Blockchain did come with lots of benefits compared to old centralized models. A decentralized standard would mean that there would be no discrepancies or misuse of power. More so, everything would be transparent.
Anyhow, they have over 250 organizations so far working together, and recently they teamed up with another consortium Enterprise Ethereum Alliance to include a different kind of tech.

Why Open-Source?
I mean, they could’ve commercialized the whole project or any other projects under it and made tons of money on top of it. But they made the codes of each of their projects public property. But why? Basically, because proprietary technologies don’t actually have all the benefits that come with a blockchain open-source platform.
In many cases, the vendors lock the system if anyone tries to make changes to their codebase. More so, they also even as a fee, and sometimes that can discourage people from using it.
On the other hand, open-source technologies are open, and developers can make changes to them. So, the development or adding of any new features is extremely faster. More so, it gives a scope for new innovations as well.
Thus, making it an open-source project makes a lot of sense as the primary target is to make blockchain accessible to anyone.
Also, it’s a popular method and also reliable. So, as a result, open-source platforms will get more exposure.
Let’s check out their architecture in the Hyperledger tutorial for beginner’s guide next.

Hyperledger Tutorial for Beginners: The Architecture
Modular Design
All of the projects under Hyperledger come with a modular design. Basically, the modular design makes sure that all of the frameworks are extensible in every way. Anyhow, they typically use common standards in building blocks that are suited for any kind of scenario.
More so, the modular structure helps in the Hyperledger developer tutorial as they can experiment with it without affecting all other codes.
It’s a great strategy in making the distributed ledger technology as you can reuse any other model previously built.
Let’s check out the next one in this Hyperledger tutorial for a beginner’s guide.
Extremely Secure Platform
It’s one of the important factors of any kind of blockchain platform. In many cases, enterprises deal with a high level of sensitive information. And that information needs a high level of security by all means.
But it can become difficult to maintain full security when you are dealing with a lot of data flows and codebases. Thus, Hyperledger introduces a new form of security by using the immutability and decentralized nature of the blockchain.
According to, the Hyperledger developer tutorial, all of their projects go through vigorous testing to figure out any loopholes in the system. Thus, it ensures that no hackers can get access to the network and manipulate your data.
More so, according to their Hyperledger developer tutorial, they also have added layers of blockchain security to help you harness the power.
Another great news is that all of their codebases go through regular auditing to see any discrepancies in them. If they manage to find any, it’s immediately solved.
Let’s check out the next one in this Hyperledger tutorial for a beginner’s guide.
Interoperable
Blockchain technology needs to be interoperable in order to get into every aspect of our lives. However, without interoperability, there’s no chance it can work. So, when multiple networks can communicate with each other and exchange data, all of them can work more efficiently.
Thus, Hyperledger wants to introduce blockchain interoperability to help make all the applications and other contracts portable to any kind of device. More so, it would connect all of our industries to one hub where everything is connected.
Using the interconnected data streams, efficiencies would skyrocket, and it would save a lot of time as well.
Cryptocurrency-agnostic
The best part about this platform is that it doesn’t have any kind of cryptocurrency to help run the system. Basically, in other platforms, you see a form of token or cryptocurrency that they use to use certain functions of the network.
But not in Hyperledger. In reality, all the projects under it are cryptocurrency-agnostic. But why, though? Well, because Hyperledger believes in the core technology and doesn’t want to administrate any cryptocurrencies on the platform.
However, as many of the enterprises may need a digital form of money, they’ll give you an option to issue your very own token on the platform.
High-end API Support
According to, Hyperledger developer tutorial, all of their projects include high-end API support. More so, every single API from their solutions offers the best of the best blockchain features, and all of them can handle interoperability.
Anyhow, Hyperledger APIs will help you communicate with their core network from any external client program and network. Most importantly, it helps out all of the distributed ledgers to bloom properly and be capable of handling many other use cases.

Hyperledger Fabric
Hyperledger Fabric is a modular distributed ledger network that offers developers the highest quality of applications. The best part is that with the help of Hyperledger, you’ll get flexibility, scalability, confidentiality, and resiliency.
Anyhow, whatever your company may be or what industry you work in, Fabric can surely help you out in that.
In reality, Fabric architecture uses a general-purpose programming language, and that makes this platform completely free from any native tokens.
As Fabric is the most popular one among all other active projects of Hyperledger, it offers a diverse community to help you out. There are also multiple Hyperledger fabric use cases suitable for enterprise environments.
Modularity
Every element in Hyperledger Fabric is modular. So, if you have a pluggable consensus or identity management system, you can easily turn it into various enterprise blockchain use cases.
Basically, the platform will contain the following modules –
- Ordering Services: It allows the nodes to order a transaction, and then the system broadcasts them to other nodes. Also, this module is pluggable.
- Membership Service Providers: It offers you an option to create cryptographic identities for the members on the platform. Also, this module is pluggable.
- Peer-To-Peer Gossip Services: It’s optional, but it helps to distribute the output of every block among all other nodes.
- Smart Contracts: In reality, this option allows you to run smart contracts in a contained environment.

Functioning Smart Contracts
Smart contracts in Hyperledger Fabric are called chaincode. Furthermore, it’s business logic and a bit different than typical smart contracts. In this one, it goes from executing, order, and validations.
It means that firstly it will execute a transaction and check for its validness. Next, it will place the order in the consensus protocol. After the validation is confirmed, it follows the specific rules of the contract and executes that. With the new design, the project can easily scale up and enhance performance.
Hyperledger Fabric Developer Tutorial
Prerequisites
Before using the platform, you would have to install certain Hyperledger Fabric prerequisites into your device. Without these prerequisites, you can’t use the Hyperledger Fabric in your device.
Installing Git
First of all, you have to download the latest version of git and install it. In case you have any issues with running curl commands.
Installing cURL
According to the Hyperledger Fabric smart contract tutorial, if you still have issues in running curl commands from the doc files, then download the latest version of the cURL tool and install it.
Docker and Docker Compose
According to the Hyperledger Fabric smart contract tutorial, you’ll have to install all of the following software to operate or develop in Hyperledger Fabric –
For Windows 10, *nix, or macOS, you’ll need Docker version 17.06.2-ce or more than that.
For older versions of Windows, you’ll need to install Docker Toolbox again and Docker version 17.06.2-ce or more than that.
According to the Hyperledger Fabric tutorial, when you’ll be installing Docker for Windows or Mac, the Docker Toolbox will also install the Docker Compose. But if you already had it installed, then you have to check if you have version 1.14.0 or greater installed or not.

Hyperledger Indy
The Hyperledger Indy architecture is a one-of-a-kind model in the blockchain niche. In reality, it’s also a distributed ledger that comes with a load of reusable components along with tools and libraries. More so, this platform is made specifically for identity-based solutions.
Thus, anyone can use this platform for organizations, administrative domains, and applications. It means that you’ll have complete control over your very own identity, and no one can control it in any way.
However, if you are not authorized in organizations, then they may reject your access, but they can’t claim you have a fake ID. Anyhow, enterprises can use this platform to rely on a single source of truth, as every document on the platform will go through verification. Thus, it makes Indy a good platform for using in digital identity solutions.
Another plus point is that you can choose only to expose the information that is required and leave other information a secret.
Main Features of Hyperledger Indy
- Self-sovereignty: On the platform, you can store any artifacts on the ledger. More so, all the artifacts will have cryptographic encryptions to secure them. No one other than you can delete your identity or make changes to it.
- Privacy: You’ll have the full privacy of your documentation. That’s why the platform offers privacy options leaving no trail of data that can connect you from one platform to another if you don’t want it.
- Verifiable Claims: When you are trying to claim any new documentation, such as birth certificates, licenses, etc., you would need additional proof that you are who you are claiming to be. Anyhow, if anyone gets access to these, they can easily manipulate them. Thus, Indy uses zero-knowledge proof to disclose certain data without revealing the full document.
- No-hacks: According to the Hyperledger Indy tutorial, no one can get access to your files. In reality, the centralized servers aren’t enough to offer security to your documentations. As a result, there are lots of identity thefts happing every day. But with Indy, every single document once on the ledger stays on the ledger.
