What is Hyperledger in Blockchain?

The Linux Foundation (the same corporation behind the Linux Operating System) launched the Hyperledger blockchain initiative in December 2015. This project was established as a core for both the collaborative production of fully accessible blockchain technology and distributed ledgers.

What is the need for Hyperledger in Blockchain?

Hyperledger was founded to advance the discovery as well as the adoption of cross-industry blockchain systems. It is backed by major corporations such as IBM and many others across a wide range of sectors, including finance, IoT, banking, industry, etc. 

One thing to keep in mind is that Hyperledger was designed to assist and stimulate the advancement of blockchain technology, not any particular cryptocurrency. 

Blockchains can transform online transactions by fostering faith, openness, and trustworthiness, as per the Hyperledger webpage. It was created solely to fulfill that ability. Around 100 companies, comprising industry titans like Nokia, IBM, and Samsung, are part of the Hyperledger blockchain, which meets every month to supervise the development of prospective blockchain frameworks. This Hyperledger neither has any nor will have its coin. It is a vital thing to keep in mind about Hyperledger.

This directly addresses Hyperledger’s purpose: developing robust industrial applications using blockchain technology while remaining apart from the digital currency creation process.

The Architecture of Hyperledger Fabric System-

In this part of the article, we will learn about the design of the Hyperledger Fabric System.

Assets can vary from the physical (property investment and equipment) to the immaterial (software and trade secrets). By using the chain code transaction process, Hyperledger Fabric allows users to alter assets. 

In the Hyperledger Fabric system, assets are portrayed as a series of key-value pairs, with state changes registered as exchanges on a ledger path. Binary and JSON representations are available for assets.

  • Chaincode-

Chaincode is the commercial concept software that defines one or multiple assets and the transaction methods for managing the purchase (s). The criteria for accessing or changing key-value pairs or any other dynamic database entries are enforced by Chaincode. Chaincode operations are started with a transaction idea and run against the ledger’s existing state information. The implementation of Chaincode generates a collection of key-value writes that can be sent to the system and implemented to the ledgers of all users.

All value changes in the fabric are recorded in a sequential, damage-resistant ledger. Chaincode abstractions (‘transactions’) supplied by interacting parties cause state shifts. Every transaction generates a collection of asset key-value pairs that have been created, updated, or deleted in the ledger. 

A blockchain is used to store permanent, sequential records in blocks, and a database file is used to keep track of the present fabric state. Each channel has only one ledger, which performs an error handling check is conducted before adding a block to guarantee that the conditions of assets that were fetched have not altered since chain code processing time.

  • Security- 

Hyperledger Fabric is the foundation of a transactional system in which all members are acknowledged. Cryptographic licenses are related to businesses, networking equipment, and application developers or client apps via Public Key Infrastructure. As an outcome, data access management on the system and channel stages can be regulated and managed. In this way, it makes it secure. 

  • Consensus-

Consensus has gradually been associated with a specific method within a particular target in distributed ledger architecture.  On the other hand, consensus entails more than just responding on transaction execution, and this distinction is underscored in Hyperledger Fabric by its central position in the whole transaction pipeline, from request and approval to ordering, verification, and pledge. In a word, the consensus is the total authentication of the accuracy of a group of transactions that make up a block.

  • Confidentiality-

Hyperledger Fabric uses an unchangeable ledger and a chain code that may edit and alter the present state of objects. A ledger can operate within the range of a channel — it could be broadcast throughout the existing system or privately run to include precisely a limited number of users. 

After all these situations, these parties will make a different channel, isolating and segregating their transactions and the database. A chain code can only be deployed on peers, which needs the information to the asset states to execute reads and updates to overcome situations that seek to fill the space between complete transparency and confidentiality.

When companies on a network want to maintain their transaction information secret, secret record keeping is being used to store it in a personal library that is logically independent of the channel record and available only to the allowed group of companies. 

In this way, the channels help keep away transaction process from other networks, and the collections maintain the secrecy of the information. 

What do you mean by a Blockchain?

The blockchain contains certain parts like – distributed ledger, consensus, and innovative contracts.

Now let’s see how these parts work.

  • Distributed Ledger – 

A distributed ledger has been at the core of a blockchain network, and it tracks all of the network’s transaction activities. Because it is repeated across multiple network users, each of those who collaborate in its upkeep, a blockchain ledger is generally defined as decentralized. We’ll learn how decentralization and partnership are essential characteristics that reflect how businesses transfer products and activities in everyday life.

Furthermore, to be decentralized and collaborative, the data collected to a blockchain is available only when using cryptographic methodologies that ensure that once a payment has been introduced to the ledger, it could not be altered. This feature of “immutability” makes it much easier to identify the authenticity of details because individuals can have the proper information that has not been modified after the transaction. It’s for this reason why blockchains are often referred to as “proof systems.” 

  • Consensus-

Consensus is the procedure of maintaining ledger transactions synchronized throughout the platform, ensuring that ledgers only refresh when the relevant users confirm transactions. That is when ledgers make changes in their information. They usually update with the actual transactions in the very same sequence. 

  • Innovative contracts-

A blockchain network includes intelligent agreements to offer regulated accessibility to the ledger to ensure the continuous updates of records and permit various ledger functions (transactions, queries, and so on). Smart contracts could be developed to allow users to perform some features of transactions mechanically and be a crucial method for encrypting data and preserving it clear across the system. 

For instance, a smart contract may be designed to specify the pricing of transporting goods, with the price changing based on how speedily the product delivers. When both clients accept the conditions and are documented down in the ledger, the relevant payments are sent immediately once the goods are received.

Afterward, you’ll know more about ledgers, smart contracts, as well as consensus. In the meantime, it’s OK to consider a blockchain as a standard, duplicated payment platform that is only updated via intelligent contracts and kept continually synced by a collaborative procedure known as consensus.

What are the advantages of Blockchain?

  • The Chain’s Accuracy 

A network of hundreds of computer devices approves payments on the blockchain system.  This virtually eliminates human intervention in the authentication process, providing in lower human mistakes and a more reliable collection of data. Even if any of the computers on the system makes a technical fault, it would only affect one blockchain record.  To transmit to the remainder of the blockchain, that mistake would have to be committed by a minimum of 51 percent of the network’s machines, which is nearly impossible in a vast and developing network like Bitcoin’s.

  • Transactions in Confidentiality 

Numerous blockchain networks function as open databases, allowing anybody with internet service to access the network’s recent transactions. Because users have accessibility to transaction details, they do not have access to personal information about the people conducting the payments. It’s a frequent misconception that blockchain networks such as bitcoin are private, but they’re not.

  • Reduced Costs 

Clients typically charge a bank to authenticate a trade, a registrar to endorse paperwork, or a preacher to marry them. The blockchain removes the requirement for third-party authentication, as well as the fees that come with it. Once businesses receive credit card transactions, they must charge a small price to banks and payment service providers to handle the operations. On the other side, Blockchain has no centralized power and only has a small number of transaction costs.

In a nutshell, blockchain networks help decrease the time, expense, and danger involved with confidential data and operations by coordinating the corporate network via a shared ledger while also boosting trust and transparency. You now have a better understanding of what blockchain is as well as why it is helpful. There are numerous other variables to consider, but they all connect to the basic principles of data and process exchange.

Now let’s see how to develop an application using HyperLedger Fabric System.

The first step is to construct and deploy the network. Your application will be useless without a functioning network. For installation, you can follow an online guide. To go to the repository containing the prototype network, run the below command when everything is done. 

cd fabric-samples/first-network

Then, to execute the network, apply the byfn.sh script. Running this system will improve network connection and deploy critical components such as containers, peers, chain code, and other tools that will aid the other processes. 

Now it’s time for creating artifacts for creating this run the given command. After that, hit “Y” when prompted for verification. 

.byfn.sh generate

In this step, we will power up the network. To enable additional peers to connect to the network, this will start all of the parts, including chain code and containers. To activate the network, enter the following command: 

./byfn.sh up

The next step will be launching the network. To start the network, run the following code :

./startFabric.sh javascript

Now you will have everything you need to construct your application once the network is launched, from orderers to peers to certificate authorities.

One of the popular and widely used Blockchain frameworks is Hyperledger Fabric, similar to the concept of Hyperledger Sawtooth technology.

Being an enterprise-class framework based on DLT, it focuses on aiming to offer versatility and modularity. The modular architecture of Fabric can be out to diverse uses in the industry of the technology of Blockchain.

Hyperledger Fabric: Most Essential Features & Applications You Need to Know

The core feature of Hyperledger Development:

Hyperledger Fabric development offers various features as described below:

  • A consensus of plug-&-play is featured by Hyperledger Fabric.
  • It supports Solidity and EVM.
  • It offers enhanced flexibility to data privacy. It performs the process of data isolation through “channels” and also leverages ‘collections’ of private data.
  • Hyperledger Fabric is incorporated with permission and highly modular architecture.
  • The smart open contract control model of Hyperledger Fabric contributes to flexibility.
  • The lower latency of confirmation makes it preferable.
  • Hyperledger fabric supports query-able data.
  • It supports continuous operations, along with an asymmetric version of support and rolling upgrades.
  • Multiple language-based smart control support for coding languages like JavaScript, Go, and Java is available.

The organizations (referred to as members) that come along for building a consortium together set up the permission Blockchain network, Hyperledger Fabric.

The architecture of network-within-network is probably the finest characteristic of Fabric. Although network members keep intention for collaborating, they keep up discreet relationships in the network because every member organization needs to hold their privatized data securely.

The network’s every member organization makes a setup particularly for their peers participating in the said network. Cryptographic elements like Certificate Authority are used to configure the peers.

Clients in the organization send transaction invocation requests to peers. They leverage the REST web service or Fabric SDK and communicate with the network of Fabric. The transaction invocation request is triggered by the chain code already installed in peer nodes.

All peers preserve only one ledger on every channel to which they subscribe, as the network of Fabric is contingent on DLT in the Hyperledger Blockchain framework. The peers in the network of Hyperledger play different roles, unlike Ethereum. Following are the types of peers:

  • Anchor peer: While configuring a channel, a single or a bunch of anchors are simultaneously configured. The endorser sends an update to anchor peers regarding the transactions. The anchor peer receives it and sends the update to various other peers. Anchor peers come with a discoverable feature and thus can be effortlessly found out by any peer.
  • Endorser peer: These nodes simulate the outcome of a transaction besides validating it and executing the chain code. But these peers cannot update the ledger.
  • Orderer peer: These peers act as the chief interaction channel of the network. An Orderer peer makes the block followed by sending it to different peers. It maintains a constant ledger set in the network.

Applications of Hyperledger Fabric:

The applications of Fabric in Blockchain Hyperledger platforms are described below:

  1. Diamond Tracing:

The diamonds pass through multiple hands during extraction and mining. And it is prone to fraud and double-dealing. So, strict measures are required. The Hyperledger Fabric allows miners, retailers, separators, and exporters to develop a consortium. The Fabric keeps the whole process transparent by recording and tracking every transaction.

2. Digital payments:

Hyperledger being a decentralized private network of Blockchain, it allows secure transactions. Fabric focuses on making the financial sector’s Interledger. It facilitates easy carrying out of transactions via similar channels. It encourages communication amongst various international payment systems available worldwide.

3. Digital identity:

Cybercrimes and data breaches are growing. And the companies are concerned about the security of their network and credentials. Blockchain technology is now incorporated to boost this safety.

4. B2B contracts:

The automation of contractual agreements is enabled, as Hyperledger Fabric allows enterprises to codify the business contracts. It also facilitates safety and security. The network-inside-network architecture of Fabric makes sure that sensitive and confidential data of B2B contracts are safe and secure.

5. Food supply chain:

Fabric is used to form consortiums by the food production companies and sector. This enhances the entire process of food supply and gains customer trust. Regardless of the time, the data of the food supply chain, its history, and the present location of a food item can be accessed.

Conclusion:

The above-mentioned features and applications of the Hyperledger framework signify that it holds a robust capability for the technology of Blockchain. Thus, Hyperledger development tools can be used for making efficient and powerful non-monetary and industrial applications.

What exactly is Blockchain?

A blockchain is a disseminated network that comprises computer systems associated with the Internet, which all together keep the account of transactions. In the Blockchain, one record is dispersed and protected across the system. Each computer in the group approves the exchanges. However, nobody has power over the network, not like various clients functioning in a centralized network. 

A blockchain incorporates a sequence of blocks, which are information units used to store value-based data of the organization. To add a block into a blockchain, these steps ought to occur:

  • When an exchange is performed, then it should be confirmed by a group of computer networks. The exchange should be compiled in a block; after getting approval from the network group. The digital signature of the sender and the receiver and the dollar’s value has to be stored in a block. 
  • A block should be given a hash to separate it from different blocks. This block additionally contains data of the hash of the newest added block into a blockchain. When hashed, this block can be put into the Blockchain.
  • After the inclusion of a new block in the Blockchain, the complete information of this exchange will be public, and any user in the network can explore this exchange data, for example, who sent it? Who received it? Who added this exchange to the block? When did the exchange occur? And so on. The information is apparent and auditable yet not editable.

A block is only digital data. A “chain” is characterized as a common information base. In this way, when we say Blockchain – we intend to discuss the digital data which is kept in a public data set.

When did Blockchain first appear? 

The very first appearance of Blockchain was seen in 2008. It was introduced by an individual named ‘Satoshi Nakamoto.’ Nakamoto improved the blockchain structure effectively, utilizing a Hashcash-like strategy to keep records of time and date of added blocks without expecting them to be endorsed by a central party and embedding boundaries to balance out the rate at which blocks were to be added to the chain. Next year, this blockchain structure was recognized as a central part of the cryptocurrency bitcoin, where it acts as the public record for all exchanges carried on the network. 

In August of 2014, the size of stored records of all exchanges that have happened on the bitcoin blockchain network filled up to 20 GB. In January 2015, the size had reached nearly 30 GB. This size expanded from 50 GB to 100 GB between January 2016 to 2017. While reaching halfway to 2020, this record size exceeded 200 GiB.

Who is behind Blockchain technology?

It is essential to learn about the historical background of Blockchain for Blockchain supporters and Blockchain prospects. Thus, to help readers to comprehend the Blockchain advancement, let us learn the  history of this technology:

1991-2008: Creation Period of  Blockchain Technology

Blockchain emerged in 1991  when W. Scott Stornetta and Stuart Haber deliberated what the world has come to know as a “Blockchain.” Their early work included shaping a cryptographically secured blockchain where nobody could alter timestamps of records. 

In 1992, they updated their technique to consolidate Merkle trees that improved proficiency hence providing the assortment of more reports on a solitary block. Nonetheless, in 2008, the term “Blockchain” began to acquire importance when Satoshi Nakamoto ingrained his idea of Blockchain in the blockchain space. 

Satoshi Nakamoto is credited as the master of blockchain innovation. There is not much knowledge about Nakamoto as individuals speculate he could be a single person or a group that molded Bitcoin, the primary application of digital roster technology.

How is a Blockchain created?

Here are steps that are needed to create a blockchain:

Step 1: Identifying a suitable Use-case

There are three use-cases where blockchains do very well:

  • Data Authentication and Verification: It focuses on encryption, inflexible storage and digital signatures, creation of private and public keys, and verifying digital signatures.  
  • Smart Asset Management: This focuses on disbursement, revenue, trade, bond, and retirement. In crypto, real-world properties are represented in the form of a token, for example, land, infrastructure, gold, silver, oil.
  • Smart Contracts: This focuses on trade between dealer and buyer with smart contracts.

Step 2: Selection of Suitable Consensus Protocol

Depending on your requirements, you need to choose the right consensus protocol among:

  • Deposit based consensus
  • Proof of stake
  • Delegated Proof of Stake.
  • Derived PBFT
  • Byzantine fault-tolerant
  •  Federated Byzantine Agreement
  • Redundant Byzantine Fault Tolerance
  • Federated consensus
  • Proof of Elapsed Time
  • Simplified Byzantine Fault Tolerance
  •  Round Robin

Step 3: Selection of a Blockchain Platform

This depends on your choice of consensus protocol. Many of them are cost-free and open source. Here are some examples:

Ethereum, Hyperledger Fabric, Quorum,
HydraChain, Stellar, Hyperledger Iroha,
Open chain, Hyperledger Sawtooth Lake, and many more.

Step 4: Node designing

Blockchain systems can be designed as private/public,  permission-less as well as with permission, or even hybrid. 

Another important factor to be considered at this step is whether the nodes are running on-premise or in the cloud. Also, the selection of operating systems and tasks related to hardware configuration such as processors, and memory and disk size is to be done in this step. 

Step 5: Designing the Blockchain Parameter Configuration

Usually, blockchain platforms require a thoroughly plotted configuration for elements like permissions, atomic trades, key management, asset issuance, multiple signatures, address formats, hand-shaking, etc.

Step 6: APIs

Most platforms offer pre-built APIs, while others don’t. The issues that you’ll need APIs for are: 

  • For developing keys and addresses.
  • Conducting auditable processes.
  • Performing data verification by using hash and digital signatures.
  • For holding data and its recovery.
  • Managing smart-asset, I.e., distribution, bond, donations, business, etc.
  • Creating smart contracts.

Step 7: Building admin and user Interfaces

At this step, you’ll select the programming languages. You’ll also have to pick external databases and servers.

Step 8: Adding smart technology 

Boost the potential of your Blockchain solution with the addition of Artificial Intelligence (AI), cloud, data analytics, biometrics, machine learning, and bots.

Closing Thoughts

The Blockchain provides amazing advancements in security, decentralization, transparency, and unchangeable data. These qualities make it a perfect tool for future applications. 

It has marked its territory in many industries, and many more yet have to embed it.

Codezeros

Executing an IT project requires you to depend on the software that is well documented and has a better and active developer community. Having an active community and strongly responding developer community helps in searching out information for your project easier.

The active support and a great performance from the software help in steering programming and fixing bugs. Even the blockchain system’s development is more similar to this. Thus, opting for Distributed Ledger Technology (DLT) can be an advantageous option if users want to derive out information.

So, let us talk more about it below.

Choosing a Distributed Ledger Technology

Criteria to look out for:

So, in recent finding, it is concluded that Blockchain Research Lab had been associated with selecting the DLT to facilitate the DiBiChain blockchain project. To make the products more optimized, this project was liable enough for creating a virtual picture of the product’s life cycle.

From the vast list of available DLT creation services, any one of them can be used to formulate DibiChain. So, among the large number of DLTs, anyone with the vastest technical characteristics can be used.

However, there are many other criteria that you can consider before selecting the apt Distributed Ledger Technology, like the documentation’s quality, how well the community is active and how popular the technologies are.

Study of 15 different DLT technologies:

Some recent reports have been published as an assessment based on the explorative scrutiny of resources and community of candidate technologies. In that report, 15 different DLT implementation and integration technologies were scrutinized based on the present document, their popularity, and how effective the developer’s community is.

The 15 technologies, which were scrutinized, are also studied based on the connection with resources such as Whitepapers, documentation, video channels, Whitepapers, and chats. The name of the DLT technologies is Bitcoin, Cosmos, Corda, Hedera Hashgraph, Hyperledger Fabric, Ethereum, Hyperledger Iroha, IOTA, Hyperledger Sawtooth, Quorum, Tupelo, MultiChain, WRMHL, Stellar, and Tendermint.

The result after scrutinization:

Upon scrutinizing, it is found that technologies that are of Hyperledger, Corda, Ethereum, Quorum, Bitcoin, Tendermint, Hedera Hashgraph, and Stellar have complete documentation amongst others.

However, all DLT implementation technologies have a dedicated community for group chats with developers that can be contacted and be asked for help.

Utilizing the GitHub metrics:

Another analysis was made with the GitHub metrics for finding the collaborative effort made by the open-source DLTs in comparing one another. On GitHub, analysis was based on three things, i.e., the “fork,” “stars,” and “commits.”

These three metrics determine DLT’s effort on helping the public with a generalized interest in knowledge and also analyze the effort that was devoted by the Distributed Ledger Technology.

So, here somebody utilizing “stars” means it points out a certain that technology has helped them throughout the project, and they want them to take their help in the future. The term number of “forks” refers to the number of projects that the developers have worked on. And from the developer’s side, they use “commits” to deliver the changes that they have made in the project and distributed them to the common people.

So, based on all three factors mentioned above, Ether and Bitcoin came on top considering all three factors.

On the other hand, Hyperledger Fabric performed well when compared to other technologies in terms of several forks and stars. This makes it certain that their community has a solid curiosity for this particular technology.

In contrast, others such as Corda, Stellar, Quorum, and Tendermint were close in terms of “stars” and “forks.” Ethereum, Quorum, and Hyperledger Fabric have an equal number of commits, and that determines their dedication towards the project. However, Quorum technology is a part of Ethereum. Thus, it gets all the commits obtained from the parental project of Ethereum.

And to trace out if the development of DLT integration technologies is still going on actively, the particular date of the newest “commits” need to be considered. This explains if the technology is actively participating or not.

Hence, only two from the long list have last been active for one month. Like MultiChain and Cosmos, these technologies have been active in the last eight months and three months, respectively. And this, therefore, determines that most of the current open-source-based development communities are inactive.

Conclusion

It is derived that the study here unfolds the differences between different DLT blockchain technologies.

Technologies and their developer community such as Bitcoin, Ethereum, Stellar, Quorum, Tendermint, Corda, and Hyperledger Fabric have done better work by investing their time and effort on delivering the project.

On the contrary, many other technologies have better resources that can support the better development and formulation of the blockchain project.

So, all these analyses and their result can help you determine which Distributed Ledger Technology to consider, so that can be useful for your project and help you advance your DLT-related project.
