  • Distinguish between Hyperledger and Ethereum.

The major difference is that Ethereum is a public blockchain, whereas Hyperledger is permissioned and private. It is designed to create an enterprise-grade, open-source, distributed ledger framework to improve business transactions. Ethereum, on the other hand, runs the Smart Contracts on the EVM for applications that are attributed to being decentralized and are for mass consumption. Hyperledger is for a B2B business, whereas Ethereum is a B2C business. Another difference is that Ethereum utilizes Solidity programming language, whereas Hyperledger utilizes Golang. 

  • What is Hyperledger Fabric?

Fabric is one of the blockchain projects within Hyperledger that has a ledger, uses smart contracts, and offers a system by which participants can manage their transactions like other blockchain projects. It has a private and permissioned network whose modular architecture maximizes blockchain privacy, flexibility and eases decision-making capabilities.

  • What is Hyperledger Sawtooth?

Sawtooth is an open-source platform, a blockchain suit for developing, running, and creating new distributed ledgers. Sawtooth’s architecture is believed to be flexible and modular. It separates the core system from the application domain so that smart contracts can specify the business rules without needing to know the underlying design. This project aims at keeping ledgers distributed and making smart contracts safe for enterprise use.

  • What is Hyperledger Indy?

Like other Hyperledger projects, Indy is also a distributed ledger that comes with reusable components along with several tools and libraries, explicitly designed for identity-based solutions. It is a group of tools, libraries, and further components for digital identities rooted in blockchains.

As it offers an identity-based solution, that means one will have complete control over their identity, and no one can control it. This project is interoperable with other blockchains and also can be used standalone, powering the decentralization of identity.

  • What is Hyperledger Iroha?

Iroha is a distributed ledger software that offers varieties of libraries for developers, provides role-based access control, offers simple deployment and maintenance, and works on improving reliability, performance, and usability.

    The communication entries in Hyperledger are nodes, and the subnet of a Hyperledger network is known as the channel. 

  • Chaincode is written in which language?

It is written in multiple languages, including Golang and Java SDK. 

  • What are the types of nodes in Hyperledger Fabric?

There are three types of nodes:

  1. A client that submits a real transaction-invocation and broadcasts transaction-proposals to the ordering service.
  2. A peer node is a node that commits transactions and maintains the state and a copy of the ledger.
  3. Ordering-service-node is a node running the communication service that implements a delivery guarantee.
  • Explain Hyperledger Burrow?

Burrow is a fully-fledged blockchain node and smart contract execution engine that focuses on simplicity and speed. Burrow runs and executes Ethereum Virtual Machine and Web Assembly (WASM) smart contracts and are synchronized using the Tendermint consensus algorithm. It is an open platform that is mainly optimized for public and permissioned Blockchain; however, it can also be used as private blockchains.

  • Explain the RBFT consensus mechanism, which is used in Hyperledger Indy. 

RBFT stands for Robust Byzantine Fault Tolerance (RBFT) and is inspired by Plenum Byzantine Fault Tolerance (Plenum). It has a pluggable election strategy, and it is set to a permissioned, voting based strategy by default. All instances do ordering, but the requests ordered by the master instance are actually executed. This consensus provides Byzantine fault tolerance. The only drawback is that the more nodes that exist on the network, the more time it takes to reach a consensus. 

  • Does Hyperledger use Proof-of-Work?

No, it does not use Proof-of-Work consensus, and this is the reason why it is fast and energy-efficient as well.

  • Explain what Hyperledger Explorer is?

This is a user-friendly web application tool that provides enterprise-level visualizations that helps decision-makers through intuitive graphs, tables, etc. It is used for viewing or invoking transactions and other crucial information stored in the ledger.

  • What is Hyperldger Caliper?

Caliper is a Blockchain performance benchmark tool for Besu, Fabric, Ethereum, and FISCO BCOS networks that allows users to measure the performance of a blockchain implementation with a set of predefined use cases. 

  • What is Hyperldger Cello?

Hyperledger Cello is a blockchain provision and operation system that aims to serve as the operational dashboard for Blockchain, which reduces the effort required for creating, managing, and using blockchains. 

Moreover, Cello manages the complete lifecycle of blockchain networks, supports customized blockchain network config, and extends with advanced features as well. 

  • What is Hyperledger Grid? 

Grid is a supply-chain-centric reference implementation solution. This project provides a set of modular components for developing smart contracts and client interfaces and also showcases how to combine components from the Hyperledger stack into a single, effective business solution.

  • What is Kafka in Hyperledger Fabric?

 It is a permissioned voting-based consensus mechanism where a leader does the ordering, and only in-sync replicas can be voted as a leader.

The advantage is that it provides crash fault tolerance, and finality happens in just a few seconds. The major drawback is that it is not Byzantine fault-tolerant, which prevents the system from reaching an agreement in the case of faulty nodes.

  • Mention some of the applications of Hyperledger Fabric.

  • Supply Chain Traceability 
  • Digital Identity
  • Real-estate Transactions
  • Music and Media Rights and much more.
  • What are the advantages of Hyperledger?

  • Permission membership
  • Performance, scalability, and levels of trust
  • Data on a need-to-know basis
  • Rich queries over an immutable distributed ledger
  • Protection of digital keys and sensitive data
  • Modular architecture supporting plug-in components
  • What is solidity? 

Solidity is an object-oriented programming language for writing smart contracts for several different Hyperledgers platforms.

  • What is Hyperledger Aries?

Aries is an infrastructure for peer-to-peer(P2P), blockchain-routed interactions. This project helps in the exchange of blockchain-based data that facilitates interoperable interaction between several distributed ledger technologies and other blockchains and supports P2P messaging in various situations.

Is Hyperledger Fabric a Right Candidate for 5G Use-Cases?

October 8, 2020 by Blockchain Consultants

Wondering how blockchain technology can transform 5G? What are the current challenges associated with this new generation cellular network? In this article, we will see how Hyperledger Fabric can provide a decentralized marketplace for fifth-generation, thus benefiting and enhancing its use-cases. 

Table of Contents 

  • ABC of Hyperledger Fabric 
  • What 5G promises? What are the Glitches?
  • Decentralized Marketplace with Hyperledger Fabric
  •  The Verdict

ABC of Hyperledger Fabric 

Hyperledger Fabric is a popular project under the Hyperledger umbrella, which has a private and permissioned network and whose modular architecture maximizes blockchain secrecy, flexibility and facilitates decision-making capabilities. The Fabric platform is permissioned and has a highly modular and configurable architecture, which enables a wide range of industry use cases, including finance, healthcare, human resources, among others. It is the first distributed ledger platform to promote the use of standard programming languages such as Java, Go, and Node.js.

Hyperledger Fabric is one of the most popular blockchain projects as it holds differentiating features such as privacy, confidentiality, modularity when compared to other popular blockchain models.

Due to the versatility, scalability, and security that it provides, Hyperledger online training has recently gained popularity. If you want to learn more about the Hyperledger family and become a Certified Hyperledger Expert, sign up to Blockchain Council. 

What 5G promises? What are the Glitches?

As telecom companies start functioning out the fifth generation of cellular networks, 5G is becoming ubiquitous. The 5G network promises innovative improvements compared to 4G and is expected to offer a variety of internet-based services, including vehicular communications and smart city infrastructure that require on-demand infrastructure and resource access to function efficiently. Given the sky-high expectations, there are few concerns to operate the new technology. To meet the sky-high expectations of the vertical industries using the 5G infrastructure, there are few concerns that 5G wireless cellular network has to deal with. Securing bandwidth to operate the new technology, establishing trust in applications with strong privacy requirements, supporting and adapting to sudden changes in demand for resources are the few significant concerns that need to be considered. As the world is getting crazy about 5G, excessive human traffic can cause network congestion, and low throughput can be the other issue.

Decentralized Marketplace with Hyperledger Fabric

Now, let’s explore how a decentralized marketplace built using private Blockchain and smart contracts can transform 5G. 

Basically, infrastructure network sharing requires two-sided agreements and is limited to long-term sharing of seldom active network resources. They can neither support on-demand short term sharing requests nor the broader markets. Since there is intense competition in the telecoms industry, and therefore a centralized marketplace is not going to be a viable solution. In a centralized marketplace, a trusted third-party is responsible who takes the final decision about allocating the resources and the price.

The idea of a decentralized marketplace built using a private blockchain and smart contracts can be advantageous to the telecom industry. The decentralized marketplace can be achieved by the Hyperledger Fabric market, where multiple players, including infrastructure providers, network operators, and other service providers, could participate in the decision-making capabilities like resource allocation and pricing process in a transparent and trustworthy way without involving any third-party intermediary. 

Hyperledger Fabric aims at developing a marketplace that does not rely on a central authority to determine the market.

Blockchain in 5G can transform privacy. This is because Blockchain uses cryptographic hash functions, which ensures that all the crucial information is encrypted and secured. Decentralized Blockchain makes use of asymmetric cryptography and various hash algorithms, which helps in protecting user identities. Technology enables multiple devices to be registered with their blockchain address; thus, there is no point of identity loss. 

The Verdict 

The implementation of Blockchain with 5G gives the world a new meaning. Although it is not solely responsible for its growth, it can be seen as a key enabler that plays a significant role in transforming the telecommunications industry. Fabric makes itself a one-stop solution for 5G use-cases with its high transaction throughput and low latency rate. But the fusion of both technologies can face several challenges. Many structural and technical aspects need to be addressed to reach the detailed 5G standards. There is a need to identify and discover specific regulatory mechanisms for the application of various agreements, such as smart contracts.

Many businesses have invested in blockchain technology as it has grown enormously over the years. The demand increases many folds when bitcoin and other cryptocurrencies are dependent on it. Using this technology, anyone can carry out secure transactions with almost zero transaction fees.

Sensing the impact of cryptocurrency on the global market, many businesses have started accepting payments in Bitcoin. With blockchain development, you can also safely receive or send cryptocurrencies with other wallets. You can find a large number of reliable bitcoin wallet apps like BitPay, Airbitz, Copay, Paper wallet, etc. So, if you want a customized blockchain app for your Initial Coin Offering (ICO) or exchanges, it is necessary to know if it is worth the investment for your business. You should also know if you could afford it or not. So, this article will help you figure out how much blockchain app development will cost you.

Let’s first get started by understanding what all resources you will need:

Developers

The team who is developing the app is the major factor affecting your project as well as the budget. So, make sure that you hire blockchain developers who are skilled in developing the codes. Mostly, these developers charge average or median hourly rates. If you want to invest less, you can also outsource the task as the prices depend on many factors like country, the popularity of the company, skills, and experience of the developers, etc. However, in any case, it is advisable to consult a blockchain development company to get a better idea as to where this technology fits into your business.

Cryptocurrency

The token is a crucial part of the successful blockchain technology. It is possessed by most of the blockchain projects. So, if you are willing to integrate this technology into your business, you need to stand out among the thousands of cryptocurrency by customizing your powerful cryptocurrency.

Firstly, you will need software developers, technology experts, marketing managers, and PR executives to launch your coin in the market. Other crucial things are investors to gain project credibility, consultants to guide your technology, communication channels to engage with customers.

You might also need to promote new cryptocurrency to gain profit. Your blockchain wallet app will be successful by conveying its importance, attracting the customer, showcasing your technology, etc. After strategizing a marketing tactic, you can start creating your blockchain network.

However, if you want to build hybrid blockchain technology, it takes around a month to develop the network with the help of C++, Python, Java, Solidity, etc. The type of technology affects the least at the cost. With different technical factors affecting, you need to have a budget of around $150,000-$200,000 to create a new cryptocurrency.

Crypto Wallet

With cryptocurrency wallet software, you can securely store, send, and receive digital currencies. Did you know that to access most of the cryptocurrencies, you need to use a cryptocurrency wallet? Every application is developed for Android, Web, and iOS platforms as these are the most popular platforms used by users. You can save some of the development prices by using cross-platform technologies like JavaScript and its frameworks.

Moreover, you can work in REST API with client requirements for the web and mobile devices or else build an application that stands alone. You can consult a top blockchain app development company to understand what is best for your business as each approach has its pros and cons.

For everything you plan, you will need a dedicated developers team, a project manager, a business analyst, and a QA engineer. With the help of cryptocurrencies like Bitcoin, Ethereum and Litecoin, you can build a Minimum Viable Product (MVP) for a cryptocurrency wallet for around $40,000.

The value changes with the type of coins you add to your wallet application. As you know, the wallet app needs to be fully secure and hack-proof as it is financial software. So, it is crucial to implement advanced security features. Moreover, the security of the wallet, as well as the type of coins supporting it, also plays a part in differentiating the prices.

Conclusion:

However, it is difficult to know the price of these wallet applications but we can get average estimates of the market. The cost of the blockchain development project can be from $5,000 to $200,000, depending upon the supporting platform and application scope. So, you need to consider multiple factors before choosing the right budget for your project. You could define the scope of your wallet, supporting platform, and security needs from the start of the project to get a close estimate of your blockchain application development.

Aion Network introduces first blockchain virtual machine for Java developers

June 9, 2019 by Blockchain Consultants

Aion Network, a nonprofit dedicated to creating tools to promote blockchain technologies, announced a new virtual machine today that’s built on top of the popular Java Virtual Machine. Its ultimate goal is increasing the popularity of blockchain with developers.

Aion CEO Matthew Spoke says one of the barriers to more widespread blockchain adoption has been a lack of tooling for developers in a common language like Java. The company believed if they could build a virtual machine specifically for blockchain on top of the Java Virtual Machine (JVM), which has been in use for years, it could help promote more extensive use of blockchain.

Today, it’s announcing the Aion Virtual Machine (AVM), a virtual machine that sits on top of the JVM. AVM makes it possible for developers to use their familiar toolset while building in the blockchain bits like smart contracts in the AVM without having to alter the JVM at all.

“We didn’t want to modify the JVM. We wanted to build some sort of supplementary software layer that can interact with the JVM. Blockchains have a set of unique criteria. They need to be deterministic; the computing needs to happen across the distributed network of nodes; and the JVM was never designed with this in mind,” Spoke explained.

Aion set out to build a virtual machine for blockchain without reinventing the wheel. It recognized that Java remains one of the most popular programming languages around, and it didn’t want to mess with that. In fact, it wanted to take advantage of the popularity by building a kind of blockchain interpreter that would sit on top of the JVM without getting in the way of it.

“Rather than trying to convince people of the merits of a new system, can we just get the system they’re already familiar with on top of the blockchain? So we started engineering towards that solution. And we’ve been working on that since for about a year at this point, leading up to our release this week to prove that we can solve that problem,” Spoke told TechCrunch.

Up to this point, Aion has been focusing on the crypto community, but the company felt to really push the blockchain beyond the realm of the true believers, it needed to come up with a way for developers who weren’t immersed in this to take advantage of it.

“Our big focus now is how do we take this message of building blockchain apps and take it into a more traditional software industry audience. Instead of trying to compete for the attention of crypto developers, we want the blockchain to become almost a micro service layer to what normal software developers are solving on a day-to-day basis,” he said.

The company is hoping that by providing this way to access blockchain services, it can help popularize blockchain concepts with developers who might not otherwise have been familiar with them. It’s but one attempt to bring blockchain to more business-oriented use cases, but the company has given this a lot of thought and believes it will help them evangelize this approach with a wider audience of developers moving forward.
