Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. What Is Blockchain Development? Before delving into the different skills required for being a blockchain developer, let’s first clarify all your doubts regarding what is blockchain development? Well, blockchain development refers to a unique process wherein unchangeable DLT (Distributed Ledger Technology) is created, which is responsible for securely recording transactions and tracking assets. They may be physical assets such as money or other physical assets and can also be non-physical assets such as copyrights.  Blockchain development carries several advantages for various industries worldwide. Infact, in this technology-driven world, more and more industries are turning to blockchain technology to ensure a secure, accurate mode of sharing information. Blockchain network provides their users with a transparent delivery and shortage, which might include tasks such as tracking orders, accounts, or any other data. Some of the various sectors where blockchain technology is being used vigorously are healthcare, finance, supply chain, and real estate, among others. Thus, you can well imagine that there has been a significant increase in the demand for blockchain developers all around the world.  Advantages of Implementing Blockchain Solutions There are a series of benefits a company can derive by implementing this technology in their business. Some of them include Increased Transparency- One of the biggest benefits of using blockchain solutions for your business is that it enables a transparent view of the overall history of every transaction that is stored within the distributed ledger to all the members of the network.  With blockchain, a permanent record of transactions is shared across the network and cannot be altered. This eliminates issues with record tampering and provides more confidence in the accuracy of the data. Blockchain’s transparency also enables better auditing capabilities and compliance reporting. Network members can easily verify details and track the origins of transactions. Overall, the transparency afforded by blockchain builds greater trust between network participants by removing information asymmetry and ensuring all parties have access to the same verified information. Boosts Speed And Efficiency- Outdated manual methods can cost a lot of precious time in managing transactional data. However, with the help of blockchain, you can automate and simplify the process, thus not only reducing time wastage but also ensuring that everyone is working from the same up-to-date ledger. By eliminating manual data reconciliation and record keeping, blockchain streamlines processes and allows transactions to settle much faster. Updates to the blockchain ledger are shared in near real-time across the decentralised network, meaning all parties get access to the latest validated information quickly. This acceleration of transaction speeds significantly improves business velocity and makes companies more agile. Additionally, the ability to automate transactions through smart contracts reduces friction and human error that can further bog down processes. Blockchain solutions enable faster settlement times, near real-time data sharing, automation to reduce manual efforts, and synchronised ledgers to create substantial efficiency gains. Significantly reducing the risk of fraud- With the help of blockchain, you can have direct access to a complete audit trail, which will further help you to understand the asset’s history.  The immutable and decentralised nature of blockchain makes it incredibly difficult for any single party to tamper with transaction records. This provides a high level of protection against potential fraud or data manipulation. Additionally, the consensus mechanism to validate blockchain transactions requires agreement between multiple parties, preventing one actor from unilaterally changing records. Smart contracts can encode complex business logic to reduce loopholes. The transparency of blockchain also acts as a deterrent since all parties can view transaction histories, making it easy to detect unusual activity indicative of fraud. Blockchain solutions minimise vulnerabilities that can lead to fraudulent activities, errors, and falsified transactions by cryptographically securing data and requiring consensus to update. This provides greater assurance and trust in the validity of records for auditors, regulators, and network participants. Decreased costs- You no longer need the help of third-party intermediaries since blockchain takes care of all the tasks. It results in a significant reduction of unnecessary spending and enables faster growth.  By allowing parties to transact directly with each other through a shared ledger, blockchain removes overhead costs associated with intermediaries that provide centralised verification, clearing, and record-keeping services. Transactions can settle faster without intermediaries, lowering fees. Smart contracts automate complex processes that previously required extensive manual work, legal expenses, and outsourcing costs. The decentralised blockchain structure also eliminates single points of failure risk that can lead to very high costs. Additionally, the ability to detect fraud earlier based on the transparency of blockchain systems reduces expenses related to reconciling bad data, audits, and potential reputational damage. The streamlined processes and redundancy blockchain drives cost savings through automation, shared infrastructure, improved security, lower counterparty risk, and enhanced operational efficiency. The cost benefits ultimately accelerate growth by freeing up resources that can be invested in core business priorities.

Top Blockchain Developer Skills  As you must’ve noticed, blockchain developers have many responsibilities. To handle those responsibilities well, they need to possess a few skills as well. There are certain blockchain developer skills one need to develop and master in order to become a successful. Here are the primary blockchain developer skills you should have to face and manage blockchain development.  Cryptography Cryptography is the study of protocols that prevent unwanted parties from accessing your data. There are many essential concepts in cryptography you should be familiar with as you’ll need them during blockchain development. For example, public-key cryptography is a crucial topic of blockchain. It forms the basis for the transactions we make through cryptocurrencies. To make transactions of cryptocurrencies, you’ll need to have a wallet and the key to that wallet. That key proves your ownership of the wallet, that’s why it’s essential. Save transactions of cryptocurrencies take place through encryption and decryption of public and private keys.  Another essential concept of Cryptography is cryptographic hashing. Hashing refers to producing an output of a specific length from an input of any length. The hash function could have information with 20 characters or 200 characters, but its output would only be of the length you’ve chosen.  Certainly, cryptography is vital for the proper workings of blockchain technology. You should learn about it and its various aspects, including the topics we’ve discussed here. With its knowledge, you’ll be able to keep your blockchain data safe.  In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses upGrad’s Exclusive Software and Tech Webinar for you – SAAS Business – What is So Different? document.createElement('video'); https://cdn.upgrad.com/blog/mausmi-ambastha.mp4   Smart Contracts Since the day Ethereum entered the market, smart contracts have become a popular term in the blockchain industry. Almost every blockchain solution wants to use smart contracts for their benefit. So you can see how powerful this technology is.  Smart contracts let two parties exchange goods or services without needing an intermediary. You can compare smart contracts with a vending machine. You put in the payment, choose the product you want, get the product along with the remaining change. There isn’t a third party involved in this transaction as it’s just you and the vending machine.  Smart contracts finish only when the involved parties fulfill both of their conditions. It’s so effective because blockchain is decentralized. This means hundreds of users monitor your smart contract, and because they work on an IF-Then basis, there’s a possibility of error.  You can use smart contracts in many areas of different industries, such as law, construction, and many others. It can remove the middlemen from contracts and help in saving money and resources.  To become a blockchain developer, you should make yourself familiar with smart contracts. It is one of the essential blockchain developer skills. Multiple languages specifically focus on smart contract development, such as Chaincode and Viper.  Data Structures You’ll need to have extensive knowledge of data structures to become a blockchain developer. That’s because blockchain developers work with various data structures regularly as they have to build networks and implement them.  The entire blockchain network is made up of data structures, as even a block is a type of data structure. A block clusters transactions for the public ledger because so it is a container data structure, whereas the public ledger is the blockchain.  A block also contains a header, and the former is around 10,000x larger than the latter. As you can see, data structures are the fundamental concept of blockchain. You’ll need to master this topic to understand blockchain technology effectively.  Learning about data structures will ensure that you know the basics of blockchain. Having a strong foundation helps you in understanding the advanced concepts more quickly. We’ve already mentioned cryptography; you’ll be using both of these technologies to build reliable, useful, and secure solutions.  Also read, Blockchain career and its future growth  Blockchain Architecture To become a blockchain developer, you should be familiar with blockchain architecture. You should know what a ledger means in blockchain, what is consensus, and how smart contracts work.  Blockchain architecture has three kinds; they are: Consortium architecture The consortium architecture isn’t wholly decentralized. Here, the members of a group have full authority. In these cases, the group is made up of multiple organizations. The Energy Web Foundation is a stellar example of such blockchain architecture types. Consortium blockchains operate under the control of a group of predetermined organisations or entities rather than being fully decentralised. Participants must be granted admission to join the network. This architecture keeps the decision-making power in the hands of a select group while still taking advantage of blockchain’s benefits. It maintains privacy and allows for efficient transactions between the known group of participants, unlike public blockchains where anonymity prevails. Consortium blockchains are well suited to specific use cases like cross-border payments between a fixed group of banks or supply chain tracking between business partners. By limiting decentralised control to a curated set of verified nodes, consortium blockchains can balance the decentralisation of public networks with the centralisation of private networks. Private architecture In a private blockchain architecture, only a few people are part of the system. It’s a popular application within organizations. Sawtooth and Fabric are famous examples of such architecture. Another essential quality of such architecture is that they are not decentralized. Private blockchains operate within a single organisation where network participation and consensus are controlled by one entity. They differ from public blockchains, which have open, permissionless networks. The central authority restricts user access and mining/validation abilities. Private blockchains provide organisations with the benefits of blockchain technology, like immutability and cryptographic security, while retaining greater control over network rules. They are well-suited for regulated environments or use cases involving sensitive data. Private crypto wallet development can execute transactions faster without needing distributed consensus since a central authority approves all blockchain updates. However, they are less resistant to tampering or manipulation since their decentralised nature provides robust protection on public blockchains. Private blockchains allow centralised entities to reap blockchain advantages in a closed ecosystem with trade offs around full decentralisation. Public architecture Public architecture is the most decentralized type of blockchain architecture. Here, you can become a part of the network by mining or by making transactions. The most famous example of public blockchain architecture is Bitcoin, which you must’ve heard of by now.  You should read the whitepaper of bitcoin on blockchain to become familiar with this topic. It requires a little effort, but be sure that it’s worth it because you’ll get familiar with all the fundamentals and the advanced concepts altogether.  Read our Popular Articles related to Software Development Why Learn to Code?

What is Blockchain technology?  Before we talk about the prerequisite for Blockchain, let us understand what blockchain is. Blockchain can be defined as a digital ledger of all the cryptocurrency transactions across all the peer-to-peer networks. This advanced database mechanism allows transparent information sharing within a business network. A Blockchain database is used for storing data in blocks that are linked together like a chain.  The data cannot be deleted or modified without consensus from the network as the data is chronologically consistent. This is because, Blockchain can be used to create an immutable or unaltered ledger for tracking payments, orders, accounts, and various other transactions.  This technology has a built-in mechanism that helps prevent unauthorized transaction entries and builds consistency in the transactions’ shared view.  Why is Blockchain important?  Since you are interested in studying Blockchain technology, you must be aware of why it is so important and popular in today’s world. There are many challenges when it comes to recording financial transactions. Blockchain technology helps mitigate any legal issues that may arise due to unsupervised transactions.  This technology is used for developing a tamper-proof, decentralized system for recording transactions. All transactions made using Blockchain need to be approved by both parties and it is automatically going to be reflected on both their ledgers.  If you are wondering who can learn Blockchain? Any individual who has a basic technical understanding can learn Blockchain.  What are the characteristics of Blockchain technology?  For anybody wondering ‘is blockchain easy to learn?’ the answer is yes, as long as you have a brief idea about the prerequisites listed below. The following are some of the key features of Blockchain technology:  Decentralization  In Blockchain, decentralization refers to transferring decision-making control from a centralized entity (organization, individual, or group) to a distributed network. Transparency is used by decentralized Blockchain networks to reduce the need for trust among members. These networks also discourage members from exerting control or authority over each other in ways that degrade the network functionality.  Consensus  For recording transactions, a Blockchain system establishes rules about member’s consent.new transactions can be recorded only when a majority of the members in the network are giving consent.  Immutability  Anything that cannot be altered or changed is known as immutability. No participant will be able to tamper with any transaction once it has been recorded in the shared ledger. If there is an error in any of the transaction records, you will have to add a new transaction to correct the mistake, and both these transactions will be visible to the network.  If you want to build a successful and fulfilling career in technology, Blockchain is perfect for you. There is a lot of scope for growth in the field along with a lucrative Blockchain developer salary per month.  Prerequisite Skills Required to be a Blockchain Developer Check out our Advanced Certification in Blockchain 1. Fundamental skill and Knowledge in Technical Field There are a few skills that one should learn to become a blockchain developer. An individual should have a good knowledge of Information technologies, Information security, and computer science. The basic understanding of an aspiring blockchain developer should be clear in distributed systems, networking, cryptography and data structures.

A good understanding of how peer to peer networks work is a must. It helps in creating a good foundation in the network of computers which can range from routing to topologies of the network. All the connected computers are used for processing in the Blockchain. Byzantine fault-tolerant consensus is an essential key feature in the security of the Blockchain that one should understand. Just a basic understanding of the working and the basic concept will be enough for a beginner to start. Check out our Advanced Certification in Cyber Security Distributed systems collect the data in a decentralised manner where the data is collected and distributed among the connected users. The distributed system allows the data to be shared across the networks that are concerned with the data. The major importance of a distributed system would be that it enhances the real-time update of the data, as the data is shared across nodes that has a copy of the blockchain. Our Learners also read: Career in Blockchain! Cryptography The foundation of Blockchain is cryptography and from where the name of the cryptocurrency originated. Hash functions and digital signatures are created by using the public-key cryptography in the Bitcoin blockchain. A good background in mathematics skills can also help in the field of Blockchain for a developer. Block Ciphers, Message Integrity, and Authenticated Encryption are few concepts that one should have a clear understanding. Payments are secured on e-commerce sites by Hash Function. Cryptography is a very important feature of blockchain technology. It helps the blockchain developer to protect the data from any unauthorized access. This is carried forward using two levels namely, the key-encryotion method and another one is hashing. The function of cryptography protects the data from potential hackers. Once the data enters the systems, it gets stored in a block and gets encrypted and all of these blocks get chained together to build a network.  In order to secure the data, cryptography uses an algorithm and key that protects the data from the attacker. The encryption practice is to transform the input (plaintext) into the output that is encrypted (ciphertext). The attacker should not be able to decipher the input (plaintext) for the data to remain protected.

In the Blockchain, the data is stored in the form of blocks and not in the form of tables. Databases are replicated across the whole network, which is called distributed ledger. The integrity of data in the blocks is maintained by using cryptography. A blockchain developer should know how Data Structures work such as linked lists, graphs, hash maps, search trees and many more. The skill of building the data structure from scratch is also essential for the blockchain developer. Knowledge of programming languages like C++, C-Sharp, C, Scala, Java, Python is also required. An individual can learn all the necessary knowledge about algorithms and data structures from the repository on GitHub. The data structures facilitate the storage and access of data in a manner that is productive and efficient in its approach. The data structure is a broader term, it basically consists of organised data, data that has a relationship with each other, etc. The data structure can also be understood in terms of linked lists and stacks. As the name implies the linked lists consist of linear data stored that is connected. These nodes represent a sequence and each node has a sequence for the next code. Cryptonomic Understanding A good blockchain developer should have a good understanding of the fundamentals of Blockchain. Cryptonomic is a word that is a mix of Cryptocurrency and Economics. Cryptocurrencies are affected by the valuation of currency and many monetary policies. One can also learn about the game theory to be more explicit about the working of cryptocurrency in the market and its valuation. It will help one to understand how cryptocurrencies are kept in check without being monitored by any central bank. An individual should learn how the economic structure is working around the cryptocurrency. In order to learn blockchain knowledge of cryptonomics becomes very important. The concept of cryptonomics is a unique innovation as it removes third-party involvement while receiving the payment.  Thai brings more decentralization in the money management, fund management, or investment management systems as it removes the middlemen. 2. Smart Contracts The smart contracts are the programs which help in automating the transactions. It helps in increasing the capabilities of Blockchain without any need of middlemen or lawyers to settle the deal. The smarts contracts are made with specific conditions or in particular situations. When these particular situations or conditions are met, then the transaction will be automatically processed when required. Currently, Auditing and optimizing of smart contracts cannot be done by many developers. A developer should be very well aware of all possibilities of execution of a smart contract. He should be able to ensure that smart contracts are only executed when it is expected. Smart contracts bring more automation and transparency to the processes. It makes sure that once the pre-determined conditions are met it executes the actions. In a smart contract, the details are put in the form of a code and these codes are not arranged randomly rather there is a method or a sequence to this arrangement. So as and when these arrangements meet the requirements get fulfilled and the contract gets executed. Just like any traditional contract, there is a feature of deadline in these digital contracts as well. The smart contract enhances the security, transparency, and accuracy of blockchain technology. The feature is advantageous and allows record-keeping, reduction of middlemen, reduction of fraudulent transactions, and many more.

There are various platforms for a blockchain developer to build a DApp. Here are some of the popular Decentralized Applications: Hyperledger The main goal of Hyperledger is to develop technologies in the cross-industry Blockchain using an open-source collaborative platform. It was created by the Linux Foundation in the year 2016. The aim was to increase collaboration between entities across the network. It uses a ledger-based technology framework and blockchain to carry out the needful tasks. Hyperledger is not to be confused with crytptocurrency,  blockchain, or an organization rather it facilitates the building of the ecosystem, environment, or infrastructure for a successful blockchain system, etc. There are various layers that hyperledger uses, such as- Consensus layer Communication layer Smart layer EOS EOS stands for Electro-Optical System. The main goal of the EOS blockchain is to support industrial-scale applications. It is a decentralized operating system that has more scalability and higher transaction speed such as Ethereum. EOS is a platform based on blockchain that facilitates to development, building, or running the business applications. EOS provides secure and authorized access between the DApps. EOS also allows business applications to build secure, authorized applications similar to web-based applications.  EOS.IO and EOS tokens are the other two elements of EOS. The EOS.IO software controls and manages the blockchain software. Whereas, the EOS tokens as the name suggests are the cryptocurrency of the EOS. EOS has certain features that make the work easier for the developer such as self-describing interfaces, interface development, etc. These features make the application development and management smoother. NEO Da Hongfei and Erik Zhang founded Antshares in 2014, which was renamed NEO in 2017. NEO is not limited to one language, unlike Ethereum. A beginner can use Various programming languages such as Java and C# can be used to build DApps on NEO. It will work as a platform for digital businesses in the future. NEO is used to fully digitise the assets available on a platform to achieve the goal of a smart economy. In order for this to happen, smart contracts play a big role in the process. A digital asset is a term that holds a broader perspective. It is not only used for the digital assets buts also for the physical assets that have been tokenized on the blockchain during transfer. NEO supports transparency and security for digital assets. The assets enjoy protection validated by the digital identity and protection given to them. It has two tokens and NEO gas is used to pay for the transactions happening on the blockchain. Ethereum In 2015, Vitalik Buterin created Ethereum, which is currently the most popular platform for development. The Ethereum is fueled by the cryptocurrency called Ether. The language used in the Ethereum is called Solidity. Solidity is a smart-contract oriented language. Robustness is similar to a programming language like JavaScript and C++. Ethereum is used to create digital and secure technology. It has tokens that can be used on the blockchain technology platform. It allows the functions to be decentralised that are secure to be used. It is one of the reasons why Ethereum is used by blockchain developers. The platform of Ethereum has a native cryptocurrency that is ETH or ether. Ethereum is a blockchain technology-powered platform where ether is the currency of Ethereum. Also read, Blockchain career and its future growth  4.

What is Ripple Blockchain? Everything You Need to Know in 2024

Ripple is a popular name in the tech industry. And Ripple blockchain has created a lot of buzzes. We all know how blockchain is transforming the industry as we know it. But what is Ripple a blockchain technology? What is it, and how does it work? In this article, we’ll answer these questions. You’ll also find out why it’s such a popular solution. So, without further ado, let’s get started.  Check out our free courses to get an edge over the competition   What is Ripple? Ripple is a for-profit platform and cryptocurrency. It’s a product of Ripple Labs and is gaining popularity because of its innovative method of performing currency exchange and payment settlements. The cryptocurrency of Ripple is XRP. And this platform has over a hundred organizations as its customers all over the globe.  They use Ripple because it provides them with hassle-free and fast transactions. Ripple’s cryptocurrency, XRP, has a valuation of more than $90 billion. This valuation makes it the third most valuable cryptocurrency according to market cap. It’s right next to Bitcoin. XRP is not for consumer use, but you can buy it. It’s not exactly a currency but more of a token.  Ripple has RippleNet, a network of payment facilitators. These are primarily banks and finance companies that use Ripple for conducting transactions smoothly all across the globe.  Check out upGrad’s Advanced Certification in DevOps Learn Software Development Courses online from the World’s top Universities. Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript How does Ripple Work? Ripple is not decentralized like other conventional blockchain networks. A strong network of validating servers and a ledger secure this system. The internal ledger of Ripple guarantees customer transactions. The parent company, Ripple Labs, handles the release of coins.  But the best thing about Ripple is, its transactions aren’t limited to its cryptocurrency, XRP. You can transfer any commodity, including gold, through Ripple as long as you’re able to find a facilitator who can make its transactions. Here’s a simple explanation of how Ripple blockchain works: Check out upGrad’s Full Stack Development Bootcamp (JS/MERN)  During ancient times, when there were no banks, people used to make transfers through payment agents. Suppose you wanted to send some money to your cousin who lives in another city. First, you’d notify him that you’re sending money and give him a password for withdrawing it. Then, you’d contact a payment agent and give him the money along with the password.  The agent will take the money. He will then take it to another agent and tell him to give it to the person who can provide the password. This way, your cash can easily reach the hands of your friend.  This system works when all the agents trust each other. Ripple uses banks and finance companies as their agents. Its algorithm finds a trusted path for conducting such transactions and ensures that everything goes smoothly. On Ripple, these agents are called ‘gateways.’ In theory, you can send anything such a car, goats, or gold through this system as long as you can find a gateway that could provide this commodity to the other party.  Ripple’s ledger ensures that all the IOUs between its various agents get resolved in real-time. And its efficient system enables fast procession of transactions.  Let’s take a look at XRP tokens, which are vital for conducting transactions in Ripple.  Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses What are XRP Tokens? XRP is the cryptocurrency of Ripple. It’s a token that represents the transfer of value in the Ripple network. So, in conventional settings, companies use US dollars (or the local currency, such as INR) as the common currency for overseas transactions and transactions that occur between two places of different currencies.  The currency exchange costs a lot of time and fees. Due to this, such bank transfers can take up to 3 days to complete the process. This is where XRP comes in.  Ripple uses XRP as the common currency for performing currency exchange, which reduces the time and fees you’d have to spend. With the help of XRP, Ripple can conduct currency exchanges within seconds instead of taking 2-3 days.  This way, you get to save a lot of time. Regarding the procession fee, Ripple charges only $0.00001 for one transaction. That’s not a typo; it’s the actual fee.  The fee could’ve been zero, but Ripple has kept it to avoid scams and DDOS attacks.  Many banks and financial institutions have started XRP to facilitate their overseas transactions. The Commonwealth Bank of Australia, Santander, Fidor Bank, and 61 Japanese banks stated that they are either trying or using the Ripple network.  Difference between XRP and Bitcoin You might have some confusion between XRP and bitcoin, so let’s address them. First, XRP is limited to Ripple, whereas bitcoin is an independent cryptocurrency. Also, new coins get generated for participants who provide computational power to the chief blockchain network, in bitcoin. On the other hand, Ripple has created all the XRP coins (100 billion), and they release coins according to demand and supply. So, you can say that Ripple is a bank, too, as it handles the supply and demand of its currency.  Recently, Ripple has added a new feature in its network. They use smart contracts to release 1 billion of the XRP tokens they hold each month for funding business-related operations, selling to investors, and incentivizing customers.   Real-World Applications of Ripple Blockchain Ripple blockchain is significantly impacting the financial world, presenting real-world applications that are transforming cross-border payments and remittances. One of its primary and practical uses lies in its ability to serve as a global payment solution. Unlike traditional international transactions that can take days and involve high fees, Ripple’s blockchain ensures swift settlement and reduces transaction costs substantially.  Financial institutions are increasingly adopting Ripple’s blockchain for cross-border remittances. By utilizing its native digital asset XRP, these institutions can efficiently bridge different currencies, eliminating the need for multiple intermediaries and resulting in faster and more cost-effective transactions. Security and transparency are also strong points of Ripple’s blockchain. Its decentralized and immutable nature ensures data integrity and protects against fraud and cyber threats, fostering trust among transaction parties.  Beyond payments and remittances, Ripple’s blockchain is being explored for other practical use cases, including trade finance and supply chain management. Streamlining the tracking and verification of goods and payments enhances efficiency and reduces delays and disputes in the supply chain. Ripple’s blockchain technology is revolutionizing cross-border transactions with enhanced security and efficiency. It promises a more secure and efficient financial future as financial institutions adopt it for remittances and explore its potential in trade finance and supply chain management.

Ryan Fugger started RipplePaay.com in 2005. It was a precursor to different blockchain currencies and gave secure online payment facilities to communities. But it didn’t get much traction. In 2001, Chris Larsen and Jared McCaleb approached Ryan.  They converted RipplePay into a digital transfer system. In the new order, community consensus verified transactions instead of miners, making it quite different from bitcoin.  They started working on the Ripple Transaction Protocol in 2012. This protocol could facilitate fast transactions and direct transfers in fiat currencies. To give the system better liquidity, they started the creation of a new value token too, which is XRP.  Many banks had started using this system by 2014 as it was an excellent solution for settling remittances. It evolved from a simple transaction platform to a cost-effective solution. Ripple has been able to grow continuously since then and has over 100 clients in its network. It’s a for-profit organization and has received investments from any Angel investors.  Key Milestones in Ripple’s Development Significant milestones have marked Ripple’s development since its inception. In 2012, the company introduced the XRP Ledger and its native digital asset XRP, laying the groundwork for its innovative technology. As the years progressed, Ripple made strategic partnerships with major financial institutions like American Express and Santander in 2014, enhancing its credibility in the financial world.  The turning point came in 2017 when RippleNet, its payment network, garnered attention from prominent banks and payment service providers, gaining widespread recognition and adoption. Ripple expanded global partnerships, continuing its growth, solidifying its position as a leading blockchain solution for cross-border payments and remittances. A clear vision and a remarkable history of achievements drive Ripple’s journey.  Their unwavering determination fuels a mission to revolutionize global transactions and push the boundaries of innovation in the financial sector. Notably, Ripple’s innovative solutions have garnered the trust and recognition of major industry players. As they continue reshaping the global payment landscape, Ripple is a testament to the power of determination and innovation. Is there a Ripple Blockchain? (What is RPCA?) The relation between Ripple and blockchain technology is unique. That’s because Ripple isn’t necessarily a blockchain solution. It has a cryptocurrency, but that doesn’t use blockchain, that’s why it can be a little confusing for some people.  As it doesn’t use blockchain, you might ask, ‘How does Ripple verify its transactions?’ Because without verification, Ripple wouldn’t be able to work at all. For this purpose, Ripple uses RPCA, which is an acronym for the Ripple Protocol Consensus Algorithm.  The word consensus refers to the ‘agreement’ section of Ripple. In Ripple, you need all the nodes of the system to agree with a process if you want to perform it. Suppose there’s a group of scholars who make all the vital decisions for the country if they want to go to war with someone they put it to vote and proceed with it only if they all agree. If one of them isn’t in agreement, they won’t make the decision. They’ll work it out with each other.  Security and Privacy Considerations in Ripple Blockchain Security and privacy are crucial aspects of the Ripple blockchain stock, prioritizing the protection of users’ transactions and data in the dynamic digital landscape. Ripple employs a robust consensus algorithm, the XRP Ledger, which relies on a unique agreement process among validators. This decentralized approach enhances security, making it highly resilient to malicious attacks and ensuring the integrity of transactions. Moreover, advanced cryptographic techniques safeguard sensitive information, preserving user anonymity and transaction confidentiality.  While the Ripple ledger is public, it ensures privacy by not disclosing users’ details, like names or addresses, during transactions. This pseudonymous approach shields user identities from public exposure, bolstering privacy protection. To further strengthen security, Ripple’s Interledger Protocol (ILP) enables secure cross-ledger transactions through encrypted communication between ledgers, mitigating the risk of unauthorized access to sensitive data.  Ripple’s commitment to compliance and regulatory standards provides a secure environment for financial institutions and users, facilitating transactions confidently while adhering to legal requirements. In conclusion, Ripple takes a human-centric approach to prioritize security and privacy, fostering trust and confidence in the digital financial ecosystem. Uses of Ripple There are plenty of applications of Ripple. The most prominent ones are the following: You can perform currency exchange without paying a high fee. As we mentioned earlier, the common mediation currency is the US dollar. It costs a high commission fee and takes a lot of time to convert one currency into USD, then from USD into another. Ripple uses XPR for this purpose. You get to save a lot of time in performing international transactions. Generally, these transactions take 2-3 business days. But with the help of Ripple, you can complete this process within a few seconds. Yes, the average time of processing transactions in Ripple is 4 seconds. You also have the option of creating your own currency. As we stated before, you aren’t limited to one currency. You can use other commodities for conducting transactions as well.  Read our Popular Articles related to Software Development Why Learn to Code? How Learn to Code? How to Install Specific Version of NPM Package? Types of Inheritance in C++ What Should You Know? Limitations of Ripple Everything has its flaws, and Ripple is no exception. It has some limitations, as well: It’s not decentralized like other blockchain solutions. People use cryptocurrencies because they are decentralized, but with Ripple, you have one organization controlling the supply and demand, making it similar to a bank. As of now, Ripple Labs own 61% of the total coins, making it a monopoly. Ripple is open-source, which makes it vulnerable to attacks. It’s highly unlikely but still something to consider. Summarizing Thoughts Ripple is one of the biggest names in the cryptocurrency industry. They have a huge market cap and are growing fast. Getting familiar with Ripple and its cryptocurrency, XRP, will surely help you if you’re interested in entering this sector.

Despite its initial speculations and concerns, industries are starting to adopt blockchain to leverage the technology’s transparency and underlying security. Companies that deal with finance, legal services, design; basically, any businesses that deal with a large volume of transactions on a day-to-day basis are gradually investing in blockchain technology. In this article, we’ll look at some of the instances of how today’s manufacturing firms use blockchain’s potential benefits to support their global supply chain network. Learn Software Engineering Courses online from the World’s top Universities. Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. Check out our free courses to get an edge over the competition. Early Stages of Adapting Blockchain Large-scale manufacturing and supply chain is one of the most complex processes to understand from an end-customer perspective. With over billions of new products being manufactured, processed, shipped, and delivered daily, there are a ton of intermediaries that come into the picture, such as retailers, distributors, logistics providers, storage facilities, and so on. In such an ecosystem, keeping track of crucial changes and the order journey becomes tedious and lacks transparency from a supplier/manufacturer’s point-of-view. In early 2008, when blockchain was introduced to the world as an underlying security layer for bitcoin transactions, many industry-leading manufactures and businesses witnessed the endless opportunities this technology could deliver. Check out upGrad’s Full Stack Development Bootcamp (JS/MERN) With that in mind, companies adopted blockchain in different levels of their manufacturing process to keep track of each and every change and provide a layer of transparency to upper management & customers.  Explore Our Software Development Free Courses Fundamentals of Cloud Computing JavaScript Basics from the scratch Data Structures and Algorithms Blockchain Technology React for Beginners Core Java Basics Java Node.js for Beginners Advanced JavaScript Must Read: Blockchain Vs. Data Science: What You Need to Know Blockchain in Manufacturing – Use Cases The following real-time examples should give you a broader understanding of how large-scale industries use blockchain in manufacturing and its different stages. Check out upGrad’s Java Bootcamp.   1. Maintaining Assets in a Large Scale Industry  For example, consider an aircraft manufacturing firm (such as Boeing) that delivers industry-leading aircraft for commercial buyers (i.e., Indigo Airlines). A manufacturing company such a complex and crucial product needs to maintain several technical manuals used by the buyers, technicians for any repairs, operations, and plenty of other intermediaries. Such technical documentation needs to be regularly updated with detailed version history and information regarding who makes the changes and who access them. Not to mention, in most countries, certain aspects of aircraft manufacturing are government regulated, which could also mean that documentations are only accessible to restricted members of the manufacturer and buyer.  2. Document Version Tracking  Infosys is one of the Indian technology services providers who understood these challenges faced by their clients and adapted to blockchain in solving the transparency and trust issues for some of the world’s leading manufacturers. In the previously-stated example, blockchain can come in handy for maintaining several versions of technical publications. Since the blockchain framework is a block-based distributed and indestructible network, even the smallest changes in a document can be tracked and made available to restricted users. The subscribers of that blockchain (i.e., the buyers) can access the relevant information and the documents via predefined tokens, thus securing the framework’s contents from the rest of the population.  When bitcoin was introduced, technology enthusiasts thought blockchain was just a new logic that provided an additional security layer to bitcoin payment transactions. In an article published by the Harvard Business Review in 2017, they mentioned that tech companies such as IBM very soon realized the advent of a wide range of use cases presented by this unique technology. Soon, companies started to experiment blockchain in manufacturing and different aspects of services, such as version control, Internet of Things (IoT), money laundering, and fraud detection in banking & finance, sharing critical information as medical data to patients, and so on.  In-Demand Software Development Skills JavaScript Courses Core Java Courses Data Structures Courses Node.js Courses SQL Courses Full stack development Courses NFT Courses DevOps Courses Big Data Courses React.js Courses Cyber Security Courses Cloud Computing Courses Database Design Courses Python Courses Cryptocurrency Courses Quality Assurance and Warranty Management Blockchain-based solutions can revolutionize quality assurance and warranty management processes in manufacturing. By recording product information, including quality inspections, maintenance records, and warranty details, on an immutable blockchain, manufacturers can streamline warranty claims, reduce fraud, and ensure compliance. Consumers can verify the authenticity of products and access relevant information, enhancing their trust in the manufacturer’s commitment to quality. Factors enabling a company to leverage Blockchain in Manufacturing One common instance that is often overlooked in small-scale or startup manufacturers is how much the various parties that deal with making moving & delivering a product heavily depend on transparency. For instance, as explained earlier in the article, a manufacturing and supply chain process deals with a lot of intermediaries, such as suppliers, packers, and movers, etc. Consider a product certificate, determining the state of quality check done at each hub has gone missing in transit. This might not be a critical issue for that logistics service; however, on a larger scale, the manufacturer and supplier loses credibility in the process. Additionally, there are several negative consequences, especially in the manufacturing industry, such as environmental impact, unethical manufacturing practices that compel transparency between the manufacturer, the customer, and everyone involved in between. An unfortunate example is the 1996 Nike child labour scandal that exposed the company’s unethical practice of employing children in Pakistan’s manufacturing soccer balls. The businesses and customers who depend on these manufacturers should be provided with transparency to understand that the product they use daily is not made by endangering another human being.  Read: Blockchain Project Ideas & Topics Blockchain enabling Manufacturers to gain their customer’s trust There are some areas where blockchain in manufacturing can be of great help in gaining customer’s trust. For example, verifying the integrity claim (such as FSSAI) by manufacturers is often considered an expensive process in large-scale industries and requires proper scrutiny. Companies are manufacturing food products that go through various rounds of quality and integrity check and use blockchain to maintain an identical copy of each node (changes) in the framework. This enables product inspection and auditing in real-time, hence decreasing the time and cost consumed. Such a level of transparency makes network activities and other operations highly visible to the relevant authorities, thus automatically establishing trust.  Asset tracking is one of the other important entities in any manufacturing process. Keeping track of the moving products and their associated components, such as the product’s paperwork can become a tedious nightmare if there is no proper tracking mechanism in place. Manufacturers are starting to use blockchain to keep track of their precious goods and also to avoid shipping illegal or stolen goods as part of their production. Leveraging this technology, the company has created an indestructible sense of ownership as and when the product is made and moved out of the manufacturing warehouse.  Explore our Popular Software Engineering Courses Master of Science in Computer Science from LJMU & IIITB Caltech CTME Cybersecurity Certificate Program Full Stack Development Bootcamp PG Program in Blockchain Executive PG Program in Full Stack Development View All our Courses Below Software Engineering Courses Enhanced Supply Chain Visibility and Traceability Blockchain’s distributed ledger technology enables manufacturers to achieve end-to-end visibility and traceability throughout the supply chain. By recording every transaction and interaction on an immutable blockchain, manufacturers can securely track the movement of raw materials, components, and finished products. This enhanced visibility facilitates proactive quality control, reduces the risk of counterfeit products, and helps identify bottlenecks for improved efficiency. Smart Contracts for Streamlined Operations Smart contracts, self-executing agreements based on predefined conditions, offer significant potential for streamlining manufacturing operations. These contracts can automate processes such as procurement, order fulfillment, and payment settlements, reducing manual errors and enhancing operational efficiency. Manufacturers can leverage smart contracts to establish trust and execute transparent transactions with suppliers, distributors, and customers, resulting in cost savings and accelerated time-to-market.

Manufacturers can leverage smart contracts to establish trust and execute transparent transactions with suppliers, distributors, and customers, resulting in cost savings and accelerated time-to-market. Use of Blockchain in Maintaining Financial Assets Financial entities are another area in manufacturing that requires the lion’s share of manpower and effort. Companies that produce heavy machinery like automobiles, power grids tend to repair their production equipment more often. Since the machines are basically running 24×7, they are susceptible to wear and tear and need to be replaced or repaired for uninterrupted quality production. For instance, in early 2018, Tesla bought millions of dollars worth of AI-based robotic arms for the sole purpose of fast-tracking the electric car manufacturing process and making it available for the end-consumer as soon as possible. Tracking these purchases and investments is a major challenge. Even though companies tend to have a strong finance team that oversees those spendings, it is important to maintain those records. This is an area where blockchain in manufacturing comes into the picture and can be handy in maintaining blocks of information regarding each purchase, accessible by the top management and auditors for industry regulation. Read about: How blockchain changing finance industry Integration with Emerging Technologies By continuously monitoring the performance of machines through IoT sensors, the data can be analyzed by AI and ML algorithms to detect patterns indicating potential malfunctions or breakdowns. This proactive approach allows manufacturers to schedule maintenance activities in advance, minimizing unplanned downtime and maximizing productivity.

How to Become a Blockchain Developer? In this post, that’s what we’re about to address! We’ll take you through a step-by-step journey of how to become a blockchain developer from scratch. Let’s begin! 1. Define and establish your goals. For a beginner, Blockchain is a complicated technology. While Blockchain and cryptocurrencies can bring you a lot of profit, first you must understand what you wish to accomplish with Blockchain tech. So, you must ask yourself the following questions and find answers to them: • Do you want to work for a Blockchain company, or do you want to be an entrepreneur and create your own Blockchain products/services? • Do you want to disrupt and dysfunctional industries through Blockchain? • Do you wish to transform governance through the decentralization aspect of Blockchain? • Do you want to be a Blockchain Developer who works on Blockchain software or do you want to build applications on top of Blockchain tech? If you work as a Blockchain Developer for a reputed company, you can earn extremely high salary packages. This is because there is a significant shortage of adequately skilled Blockchain Developers. However, if you are an independent entrepreneur developing Blockchain applications, you can raise a lot of money for your projects via funding. Answering these questions will help you understand what exactly you want out of your Blockchain career. 2. Choose one Blockchain network. It’s not necessary to master all the Blockchain networks inside-out – you can choose one and specialize in it. Bitcoin, Ethereum, and EOS are the most popular Blockchain networks out there. Bitcoin is undoubtedly the most stable and widely used Blockchain tech for processing valuable transactions, but then it can handle only simple transactions. On the contrary, Ethereum was designed to overcome the limitations of Bitcoin by running ‘smart contracts.’ Smart contracts can run any arbitrary computation, unlike Bitcoin. EOS too can run smart contracts. However, EOS is much more scalable than Ethereum, and unlike Ethereum, it allows for free transactions. While EOS may look like the best choice, remember that it is more scalable which leads to a centralization of sorts (contrary to the decentralization feature of Blockchain). Thus, the smart choice here is Ethereuem since it is highly programmable, supports Ethereum tokens, and is backed by an active community of talented developers.

Get familiar with Dapps. After choosing your focus of study (Blockchain network), you should get familiar with Decentralized Apps or Dapps. More than 2,000 applications built on Ethereum (for example, Marketplaces, Decentralized Exchanges, and Gambling Dapps) already exist. So, you can get a headstart there. To explore the different kinds of Dapps, you can check out Dapp list websites like StateOfTheDapps and DappRadar. Now, it’s time to decide what you want to build. Is it a gaming Dapp or a decentralized exchange or something unique? Once you figure this out, you should figure out how you wish to develop your Dapp. For developing a Dapp, you must learn how: • The Ethereum protocol works • To write smart contracts in Solidity • To assemble all the pieces in a Dapp Growing Demand for Software Engineers in Blockchain Technology 4. Get familiar with the different libraries and development tools. To successfully write smart contracts and develop Dapps, you must learn to use the following development tools: • Truffle – it is one of the most widely used frameworks for building Ethereum Dapps. Truffle is written in Nodejs and is backed by a strong community. • Web3 – it is a library that can communicate with Ethereum clients like Geth, Parity, etc. The advantage of Web3 is that it can dynamically create abstractions (objects) to represent a smart contract. • Solc – it is the compiler of the Solidity programming language and is written in C++. It comes with its distinct Github repo. • Remix – it is an online IDE for writing Solidity smart contracts. • Ganache – it is a local Ethereum Blockchain for developing Dapps. It allows you to run a command to trigger a local Ethereum node and get ten addresses pre-funded with Ether. • Metamask – it is an Ethereum wallet designed to act as a browser extension. Dapps uses Metamask while requesting a user to sign a transaction and sanction it.

Learn Solidity to write smart contracts. While smart contracts make up the foundation of Dapps, Solidity is the primary language choice for writing smart contracts. Solidity’s is a compiled and typed language with a syntax similar to that of Javascript. Smart contracts are nothing but small programs that can run autonomously once deployed on the Ethereum network. So, once you implement them, you don’t have to do anything else – the system runs them automatically, thereby giving the admin control to no individual. Most people resort to learning Solidity with CryptoZombies, a game designed to introduce and teach the fundamentals of Solidity by generating an army of Zombies in a smart contract. While this is an exciting way to learn Solidity, you should also be thorough with the official Solidity Documentation for it is the most comprehensive guide on Solidity. It is updated regularly and will teach you the basics of Solidity, including the primary variable types, the main control structures, and the overall structure of a smart contract. 6. Develop a Dapp. Once you’ve learned the nitty-gritty of Solidity, it is time to put your theoretical knowledge to test by building a Dapp. Smart contracts aren’t exactly user-friendly, and hence, the requirement of Dapps. Dapps allow users to interact with them seamlessly. Before building a Dapp, you must understand how it works. Let’s demonstrate this through a game – Cryptokitties, an Ethereum-based game that allows players to buy and trade kitties. When you visit the Cryptokitties website, you land on the main user-interface – the frontend part looks just like a standard web app, and the backend is deployed on private servers. Then begins the Blockchain layer with Metamask. The players use Metamask to transfer Ether to Cryptokitties. After this comes to the smart contract that stores all the game data. Since the smart contract is deployed on the Ethereum network, it is hosted by multiple machines simultaneously. This is precisely the design of a Dapp. First, there’s the frontend and backend. Then you have the browser extension (here, Metamask), and then finally, you have the smart contracts. To successfully develop a Dapp, you must ensure that these three layers can communicate with one another seamlessly. There are various articles, videos, and ebooks that teach you how to build a Dapp from scratch. EatTheBlocks Pro is an excellent resource for tutorials on Ethereuem and Solidity. The last step – prepare for Blockchain interviews. As you progress through these six steps, you’ll gain an in-depth understanding of Blockchain technology, Bitcoin and Ethereum, Solidity, smart contracts, and Dapps. And as a beginner in the field, that’s all you need to get started with – the rest you can learn as Blockchain advances. We hope this helps!
