But did you know? Your site is going to be down when there is server maintenance or if a load of the server gets high. What if with blockchain, your website doesn’t require a central server? With blockchain, you can split your website content into granules and distribute it all over the internet and then link them together using a blockchain registry. Web hosting can store all types of content. You can access the stored content anytime, anywhere. Your website will be inaccessible if the server crashes or fails. But you can take the help of blockchain technology projects to solve this issue. Blockchain technology can save effort, time, and money by allowing web designers to develop websites without depending on a centralized server. The blockchain vault helps you to reassemble all content you need. The non-dependence on a central server means that there will be no occurrences of the server failing or crashing. Disk Space Renting System  The idea here is to allow everybody on the planet to rent out their unused disk space which can be attached to a blockchain registry to create a massive worldwide cloud. The idea is similar to the peer-to-peer network, but with blockchain, it’s going to be completely decentralized. This idea can be implemented as a small project, but if applied globally, it can change the face of today’s cloud storage. This concept can also be extended to your compute power and memory provided you have an ultra-high-speed internet connection. In this project, Blockchain data structures strengthen network security by decreasing single-point-of-failure risk. So, it makes a database breach harder. Moreover, it avoids unauthorized access because every user in the Blockchain possesses their key. Loyalty Points Exchange System  With payback.in being an exception, most other brands and companies reward customers with their own loyalty points. This drawback in today’s system is a very unacceptable downside as the deserving customer cannot use his loyalty points with other companies or brands. Customers also cannot exchange or trade loyalty points with friends or family. With blockchain, you can implement a project that allows consumers to combine and transparently trade loyalty rewards.  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 The loyalty points’ data is maintained using blockchain.

Blockchain essentially is a distributed ledger that is updated in real time with each network participant making a transaction. This specific feature can be put to good use when it comes to the supply chain management. Logistics demand transparency and traceability. It is clear that customers want their meat or grains to be exactly as has been promised on the packaging. Incorporating blockchain into supply chain management can certainly be a step towards ensuring that. With the potential to almost eliminate fatal errors, and minimizing courier costs, blockchain can be viewed as the next big step in supply chain management. Some companies have gone ahead and taken this step, with Walmart partnering with IBM for a project in order to trace their products much faster than traditional methods.   Here are a few use cases of blockchain which are certain to revolutionize the supply chain sector in the near future: Seafood tracing and verification News about mislabelled and ‘not-fit-for-consumption’ seafood have been floating around since 2016. The seafood industry faces a lot of problems due to difficulty in tracking produce from ocean to plate. In the event of a disease breakout due to seafood consumption, with the current supply chain logistics, it becomes tough to track and single out the source of the malicious activities. With blockchain, however, it can become a completely different story. With projects such as the Pacific Tuna project, which aims at putting a label on every tuna that makes it from the ocean to the market, blockchain applications in seafood tracing and verification is something we all can get behind. Seafood is physically tagged and the data is then stored on the blockchain to enable easy access at any time and place. The food supply chain, in general, can benefit from blockchain uses, and seafood is a particular use case that is particularly problematic and could use the extra help.

According to reports, the global fraudulent drug industry is worth about USD 75-200 billion. The traditional blockchain applications in supply chain just cannot be relied upon to bring down those numbers. The opacity of the chain is what causes the problem, and with blockchain applications thrown into the mix, the problem can certainly be reduced. Tracing drugs from manufacturer to buyer, it can be identified exactly where the problem in the supply chain lies. This can help counter fraud and prevent deaths due to counterfeit drug consumption.

As medicines need to be at a certain cool temperature, it can be disastrous for shipments if, perhaps, the AC unit fails, and the driver is oblivious to the problem. With all medicine units on the blockchain, alerts could be issued whenever the temperature falls below a certain level or for other environmental conditions so that human intervention could fix the problem. Automotive supply chain It is predicted that blockchain applications in  supply chain are set to take over the entire automotive marketplace. Ownership, payments, financing, production, and tracking are all set to be blockchain-ed soon. Looking at the blockchain applications in supply chain part of things, one of the biggest problems with the automotive supply chain is the counterfeit parts industry. As with counterfeit drugs, fake automotive spare parts can also be tracked using similar logic and features of the blockchain. At every step of the way, companies can track the parts they produce and sell so that customers get what they want. Blockchain application helps in increasing the efficiency of the recall process as well. Since data about every car/vehicle produced is on the blockchain, it could be quickly identified when a shipped vehicle encounters a fault. This can be coded into a smart contract- with faulty parts triggering some clauses in the contracts, notifying the supplier to recall one or all units produced. Another example where blockchain has helped overhaul the automobile industry is the cloud-based AutoDX, short for Auto Exchange Data. It is designed with the assistance from IBM and can handle invoices, purchases, and even transport requests. At present, more than 60 firms employ this system and plans are afoot to overhaul the general system onto a one that works on an intelligent blockchain network. The reason for this is extremely clear – when automobile makers and component manufacturers are brought onto the blockchain, it brings a clear end-to-end supply chain visibility for everyone involved, which, in turn, improves the overall efficiency of the supply chain. Using the AutoDX platform, a purchase order from an automobile manufacturer is docked into its component marker’s system. The moment this is accepted, a sales order is automatically created without human intervention. AutoDX has successfully been able to shave off a large chunk (approximately 80%) of the vendor management, invoices, and supply chain management costs which accounted for 1%-5% of total costs.

Federal organizations have also shown support, including bodies such as the US Customs and Border Protection, and the Customs Administration of the Netherlands. The Maersk-IBM joint venture aims at commercializing- Paperless trade. The amount of paperwork involved in the supply chain is too much and unnecessary. The joint venture aims to eliminate the need of paper for contracts, agreements, and other documents, by digitization of all contracts, into smart contracts, perhaps. Shipping information pipeline. This enables everyone involved in supply chain management to seamlessly exchange information, as the chain is visible openly to anyone on the network. Transparency is what the supply chain needs, and that is what it’ll be getting. The project is aimed at providing value to every stakeholder in the supply chain, be it suppliers, retailers, producers or transporters. The project is still awaiting regulatory approval but is certainly a step in the right direction when it comes to blockchain applications in supply chain management. Master the Technology of the Future – Blockchain Blockchain-enabled Smart Contracts for Efficient Supply Chain Operations Blockchain technology has introduced the concept of smart contracts, self-executing contracts with predefined rules encoded directly onto the blockchain. In the supply chain sector, smart contracts have the potential to revolutionize operations by automating and streamlining various processes.

Applications of Blockchain in Healthcare Industry
6289
After taking the finance and business sector by storm, Blockchain applications in healthcare are now all set to radicalize the healthcare industry. Ever since its inception, there’s been a massive buzz around the concept of blockchain and after witnessing excellent results that blockchain technology has brought about for the Finance sector, healthcare giants cannot help but think of ways to incorporate applications of blockchain in healthcare. In fact, blockchain has already started penetrating the industry, and there are numerous Blockchain applications in healthcare to account for this statement. Learn Software Engineer Courses 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.  According to Statista,  applications of blockchain in healthcare would have been adopted by nearly 55% of companies by 2025. Then again, a BIS research report suggests that by the end of 2025, the net worth of blockchain in healthcare will reach $5.61 billion from $176.8 million (2018). Read more about how blockchain is transforming Indian industries. What is Blockchain and How Does it Work? At its core, blockchain is a decentralized system designed to record and preserve transaction data. It is an immutable, distributed ledger consisting of interconnected transaction blocks forming a peer-to-peer network. Blockchain leverages well-established cryptographic techniques to facilitate communication among network participants without requiring prior trust. Unlike traditional systems, there is no central authority governing the blockchain. Instead, all participants maintain and share transaction records. Interactions with the blockchain and healthcare are transparent to all parties, and any information addition necessitates network verification. This characteristic enables trustless collaboration between participants while creating an unchangeable audit trail of all transactions. While the chained blocks allow you to store different data types, the transaction is one of its common forms, including financial records and product inventories.  Blockchains are different from databases as they are functional in storing data in blocks instead of tables. This will create an unalterable timeline that documents any transactions.  Blockchains exhibit a decentralized nature, facilitating easy sharing of data. Nevertheless, they can also be configured as private and centralized systems exclusively used by a single entity. Blockchains demonstrate a self-correcting mechanism. If data within one block is compromised or tampered with, the information in the other blocks within the chain cross-references each other, helping to detect and rectify the error. Security is a fundamental characteristic of blockchains. Once a block is created, any attempt to modify it requires the consensus of most blocks in the chain, necessitating changes to the cryptographic codes of adjacent blocks. How Blockchain Improves Electronic Health Record Systems? Electronic health records (EHRs) have emerged as a vital aspect of patient care, offering comprehensive, precise, and easily accessible medical treatment histories for everyone. Nevertheless, safeguarding the sensitive personal data housed within EHRs presents increasing challenges with the growing complexity of health information systems (HIS). Addressing these security concerns is where one can find the applications of blockchain in healthcare. Electronic health records (EHRs) capture patient health data in a digital format, generated and stored by multiple healthcare facilities. Typically, the healthcare provider responsible for creating the record maintains primary access. Individual EHRs often lack completeness and suffer from inconsistent management by the organizations that create and maintain them. Consequently, healthcare providers face fragmented views of a patient’s medical history. Achieving comprehensive and accessible healthcare histories through EHRs encounters additional obstacles like interoperability challenges between health information systems (HISs) and ensuring effective access control through authentication. Applications of blockchain in healthcare addresses these limitations by interlinking EHRs and distributing records ownership among all stakeholders. It incorporates various security and authentication features, offering a promising solution to these challenges. Why Blockchain for Healthcare? The healthcare sector generates vast amounts of critical data that often remains scattered and unorganized across various systems. The lack of proper and adequate infrastructure further aggravates this issue as a result of which healthcare providers (HCPs) are unable to access vital information at times of need. The absence of a centrally monitored and administered system makes healthcare data susceptible to breach and corruption. If data is stored within a particular physical machine, then anyone who has access to it can tweak the data and misuse it or even corrupt it. Check out upGrad’s Advanced Certification in DevOps  Blockchain applications, however, do not need a centrally administered system since the data will be stored within blocks of a distributed ledger, safeguarded through intricate cryptography. In a blockchain-based system, it’s not possible to manipulate and corrupt the data since the tweaked hashes will not match what’s fed into the system. In the healthcare scenario, applications of blockchain in healthcare are not only helping preserve and safeguard data integrity but are also helping pharma companies in regulating the drug supply chain, recruiting patients for clinical trials, facilitating interoperability with IoT devices, and much more. Blockchain technology in healthcare are not only helping preserve and safeguard data integrity but are also helping pharma companies in regulating the drug supply chain, recruiting patients for clinical trials, facilitating interoperability with IoT devices, and much more. Blockchain is decentralized, distributed, and immutable, and hence, it holds an immense potential to transform the healthcare sector by minimizing operational costs, eliminating corruption of data, optimizing healthcare processes, and promoting transparency.

Today, use of blockchain in healthcare is helping HCPs to maintain longitudinal patient records such as disease registries, lab test results, and health issues much more conveniently than before. Also, with blockchain, there is no fear of the data being duplicated or misused since the entire medical data of a patient is fed into a ledger along with the primary key. Using advanced and sophisticated APIs, blockchain and healthcare makes EHR interoperability and data storage smooth, seamless, and secure. Furthermore, since the blockchain system will be monitored and administered by authorized HCPs and individuals, data reconciliation would become more convenient and also cheaper. These things are not possible with conventional methods that still heavily rely on manual discretion and labour to store, organize, and track medical data. At present, the penetration of blockchain technology is still quite slow, and so are the Blockchain applications in healthcare. In 2017, IBM surveyed around 200 healthcare executives and only 16 % of the respondents agreed to adopt blockchain technology. The potential that Blockchain applications in healthcare holds for the healthcare sector can be realized only if healthcare organizations show a willingness to adopt this technology and assemble the requisite technical infrastructure for it. As of now, all we can say is although the change may be slow, blockchain and healthcare will surely will surely create a lasting impact on the healthcare industry in the future.

What is Ripple Blockchain? Everything You Need to Know in 2023
6881
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.

5978
How Today’s Large Scale Industries Leverage Blockchain to Scale Their Manufacturing Process As a foundation for distributed ledgers, blockchain is an innovative technology in the current era that is packed with a wide range of use cases. 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.

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. Integrating blockchain with IoT, AI, and ML in manufacturing means using smart sensors to collect data, storing that data securely on a blockchain, and then letting smart algorithms analyze the data to find ways to improve operations. This combination helps manufacturers make better decisions, optimize the process of production, and ensure that everything runs smoothly. Overall, the integration of blockchain with emerging technologies presents exciting opportunities for the manufacturing industry. It empowers manufacturers with valuable insights, efficient processes, and increased productivity, ultimately leading to better products and happier customers. Collaborative Manufacturing Networks Blockchain in manufacturing industry enables the creation of decentralized, collaborative manufacturing networks. Manufacturers, suppliers, and service providers can securely share data, including designs, specifications, and production schedules, on a blockchain.

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!

This becomes a digital proof and certificate of ownership. The animals are given a unique and secure digital identity that is linked to genealogical and medical data. Together, the Blockchain and AI-powered Facial Recognition allows for easy and quick tracking of lost pets.  Different Types of Blockchain & Their Uses At present, CogniPet is developing an app to help users arrange animal photos in an organized manner. This will facilitate the fast and speedy tracing of lost pets by allowing the system to browse through the database for the images of missing pets. Users will also be able to store and organize vital information (breed, location, time-stamp, etc.) about animals/pets on the Blockchain network. The data will be safe, thanks to cryptographic keys.  4. Odem  ODEM stands for On-Demand Education Marketplace. It is a Blockchain-based educational marketplace that can be used in both academic and enterprise applications. ODEM cuts out the middleman from the equation – it directly connects candidates, educational institutions, and employers to “make education and employment more affordable, accessible, verifiable and transferable.”  ODEM offers a decentralized file storage system to let instructors/students access the Ethereum Blockchain for maintaining academic records. In ODEM, educators/educational institutes and students can store credentials in the form of Ethereum smart contracts. These smart contracts will also validate the courses taken by individual students.  Once a student has completed his/her training, they can share the stored credentials with prospective employers. This helps potential employers to verify qualifications quickly. ODEM’s Skills Wizard feature helps students create a career profile for the perusal of potential employers. As for transactions in this domain, ODEM has a proprietary ERC-20 cryptocurrency token – ODE – to pay for tokenized transactions. 5. Cinemadrom  According to its official website, Cinemadrom is an “International Blockchain Network of Independent Filmmakers.” It is a platform that leverages Blockchain tech to finance, produce, and distribute film projects. Cinemadrom aims to transform the face of global cinema through its two core areas of application:  Cinema Industry – It is a perfect platform for online movies, film agencies, social networks, film markets, film studios, and film distribution agencies. Crypto industry– It supports mining, cryptocurrency, insurance, multicurrency, investments, and wallet.  With Cinemadrom, filmmakers and cinematographers can raise funds for their movie projects and also use it to distribute their finished projects. Since this is an exclusive channel for the film industry, filmmakers can get better exposure for their craft, thereby boosting the sales. They can use the platform to enter the international film industry and market. Also, as movie makers make more profits, distribution companies can increase their distribution fees. Furthermore, Cinemadrom also lets movie makers and advertisers create portfolios of target audiences based on economic, religious, intellectual, social, and geographic factors. This helps in the creation of a loyal viewer and fan base. Types of Blockchain Projects  There are five types of blockchain projects for final year students to try: ‘Fear of Missing Out’ Blockchain Projects FOMO ideas are entirely centralised since they are usually handled by an individual corporation for application internally or with a relatively small number of collaborators. They normally occur when an organisation wants to be considered creative but still hasn’t completely analysed how the blockchain would benefit the organisation or the possibility that it is the most suitable technology. Opportunistic Solutions These blockchain solutions address any existing issue, especially record-keeping-related challenges. They consistently add quality to the company irrespective of whether they are applied at work or not for some time. The possibility of eventually losing authority over data and agreements is the only disadvantage of this project type. Trojan Horse Solutions A reputable brand supports these projects. They usually have solid technological roots. They typically deal with well-known, costly and extensive challenges within a particular field. They require users to share necessary data and give up certain authority to allow the sole blockchain holder to cash in from a concentrated market. Evolutionary Solutions The evolutionary archetype of blockchain solutions is built to develop over time and utilise tokens with decentralised management. Blockchain technology makes it possible to stop inflated prices and restrict the involvement of unauthorised users on the site. Each ticket is tokenized, associates the buyer’s data to their purchase, and archives it. Blockchain-Native Solutions These solutions are developed by start-ups or larger groups of well-established businesses that seek to undermine the current ecosystem or build a fresh set of possibilities. Such a blockchain project might not initially have a decentralised and tokenized management, but it will eventually offer to evolve in that path. Why are Blockchain Projects Important? Blockchain projects are not only interesting but also quite important for developers. Some of the importance of these projects are as follows: The Structure is Decentralised  Blockchain projects are decentralised, which means a single central organisation or person does not control them. This implies that anybody and all individuals have access to blockchain projects. Blockchain Projects are Immutable Decentralised blockchain projects have the additional benefit of being immutable, which means that once data has been added to the blockchain system, it cannot be modified or deleted without authorisation to access it. Authorised Control of Data  Blockchain projects that give individuals ownership over their share will be important in the coming years. Users can decide how the information they provide is employed and who has authority over it by modifying the conditions on their end when they are given the opportunity to monitor it. Tokenization  Tokenization plays an important role in blockchain projects with source code since it lets you exercise control without needing actual ownership of a tangible thing or resource. Additionally, it enables partial ownership, which makes operations like crowdfunding much simpler than before the tokenization process. Wrapping Up These are only five among the many, many, fantastic Blockchain projects that are taking shape as we speak. Such pioneering Blockchain projects go to show that the technology indeed has tremendous potential and capabilities that are yet to be uncovered.  There is a rise in careers in blockchain technology and blockchain has tremendously changed the very face of the technology industry forever.  If you’re interested to become a blockchain developer and build smart contracts and chaincodes, checkout IIIT-B & upGrad’s Advanced certificate program in blockchain technology.

Blockchain Tutorial for Beginners: Learn Blockchain Basic Concepts
6626
Blockchain has become one of the most sought-after skills in the tech sector. According to a 2018 PwC survey on 600 executives belong to 15 different regions, around 84% of the respondents said they were using blockchain in some way. (Source) Even in India, the demand for blockchain professionals is increasing rapidly as both government and private organizations look for ways to use this robust technology. All of this buzz can make you wonder, “What is Blockchain?”  To help you find the answer to this question, we have prepared the following blockchain tutorial for beginners. It covers all the necessary aspects of blockchain so you can get familiar with this technology and pursue a career in blockchain.  Nevertheless, it is a very detailed blockchain tutorial so we recommend bookmarking this page. You can keep it as a reference to come back to it later.  Check out our free courses to get an edge over the competition. Learn Software Development Training online from the World’s top Universities. Earn Executive PG Programs, Advanced Certificate Programs or Masters Programs to fast-track your career. We’ll start our blockchain tutorial for beginners by explaining blockchain first:  What is Blockchain?  The term “blockchain” is made up of two words “block” and “chain”. We can define blockchain as a chain of blocks containing information. Blockchain timestamps digital documents so it is impossible to tamper with them or change their date. The primary goal of blockchain is to solve the problem of keeping double records without requiring a central server. A blockchain is a constantly growing ledger that securely and permanently records all transactions in a chronological and immutable manner. Let’s Break it: Ledger: It refers to a continually growing file. Permanent: Once a transaction is added to the blockchain, it becomes a permanent entry in the ledger. Secure: Blockchain utilises advanced cryptography to ensure that information remains secure within the blockchain. Chronological: Transactions occur in sequential order, with each new transaction following the previous one. Immutable: As transactions are added to the blockchain, the ledger becomes unalterable. A blockchain is composed of interconnected blocks that store transactional information. Each block records recent transactions and, upon completion, becomes part of the unmodifiable blockchain database. The process continues as new blocks are generated. Also blockchain technology tutorial is essential to understand the intricacies of this innovative technology in the real world. Check out upGrad’s Full Stack Development Bootcamp (JS/MERN) It is an incorruptible digital ledger of transactions that you can program to record nearly everything of value. The simple version of a blockchain is a chain of blocks holding records of transactions taking place in the network.  Note that the “block” in the blockchain is digital information while “chain” is a public database. In a blockchain, the blocks are spread across multiple systems and not just stored in one place.  Check out upGrad’s Java Bootcamp.   How Do Blocks Work? – Explaining the Blockchain Technology A block stores all the primary details about transactions including the time, date, transaction amount, etc. It also stores information about the participating entities of the transaction. For example, if you purchase a product from a vendor, the block would record your unique digital signature. Yes, it doesn’t store your name. In a blockchain, every user has a unique digital signature and the information about their transactions is recorded by using their unique signature, not their actual name.  The users of the blockchain aren’t the only ones who have unique qualities. Every block in a blockchain network has a unique code which makes it distinct and separate from the rest. This unique code is called a “hash”.  How much data a single block can store depends on the size of the transactions. One block is capable of hosting a few thousand transactions and the hash code ensure that every block in the blockchain is in sync with the others.   If there are too many blocks in the blockchain, the ledger size would increase accordingly. The large network of the ledger is the primary reason why a blockchain is so secure. Because it is decentralized, the failure of one block wouldn’t cause the entire network to fail, allowing the network to remain intact. Moreover, if the security of one block is compromised, it wouldn’t result in the breach of the entire blockchain.  Blockchain is a software protocol similar to SMTP for email. Nevertheless, you can’t run a blockchain without the internet.  What Constitutes a Blockchain Wallet? A blockchain wallet serves as a digital repository utilized for the storage, management, and interaction with cryptocurrencies. It empowers users to securely safeguard their private keys, which are indispensable for accessing and managing their digital assets on the blockchain. Blockchain wallets manifest in diverse forms, encompassing software wallets, hardware wallets, and online wallets, each affording distinct levels of security and convenience. A blockchain tutorial for beginners can provide valuable insights into the world of digital currencies and their management. Blockchain Use Cases Blockchain is a versatile and robust technology. Due to its unique nature, almost every industry can benefit from integrating it into its daily operations.  Potential Use Cases Blockchain is a relatively new technology and we can use it in many sectors. Following are some of the potential use cases of blockchain: Bookkeeping and Record-Keeping Every industry has to perform bookkeeping and store records. These records possess valuable information leaking of which can cause many issues for the corresponding business. Blockchain offers a highly secure way of bookkeeping and record-keeping, ensuring that unwanted parties and malicious people can’t access them.  Voting  To prevent voting fraud, governments can use blockchain technology for issuing voter IDs and recording votes. As we have discussed before, blockchain provides a highly secure solution for storing data and making changes to the data stored in the blockchain is very challenging. Blockchain can help in keeping the voting process transparent and quick.  Self-Driving Cars Apart from using AI and machine learning, self-driving cars would utilize blockchain technology to keep their data secure and safe from unwanted parties. In 2019, IBM filed a patent for a project that permits information management for self-driving cars through blockchain.  Robotics and IoT Through blockchain, you can create a decentralized network of drones and robots. It ensures that the failure of one drone wouldn’t affect the rest of the network.  Data Management in Healthcare Hospitals, nursing homes, and other medical institutes can use blockchain to store and manage data about their inventory, patients’ medical records, and the institution’s financial transactions.  Learn more about blockchain technology use cases. Existing Use Cases Here are some of the real-life examples of blockchain implementations: Blockchain in Dubai The smart Dubai office, in 2016, launched the blockchain strategy to connect entrepreneurs and developers with investors and venture capitalists. It aimed to enhance the development of Dubai and make it ‘world’s happiest city. They aim to make Dubai a fully blockchain-based city by 2020.  UN World Food Programme The UN World Food Programme had used blockchain technology in 2017 to help the rural areas of Pakistan’s Sindh region. They sent food, money, and other necessary material to the residents and used blockchain to record all the transactions. Blockchain ensured that all of its transactions remained transparent and secure.  Blockchain-based Startup Incent is a startup that allows businesses and content creators to grow their audience, reward them and monetize the content. It is Consumer retention as a service (CRaaS) solution where the system generates codes for the viewers of a specific creator. The viewers can redeem these codes and earn rewards, benefitting both the creator and the viewer. They use blockchain technology for their transactions.  Cryptocurrencies (Bitcoin, Ethereum, etc.) Our blockchain tutorial for beginners would be incomplete without mentioning the most popular application of blockchain technology, cryptocurrencies. Bitcoin, the most popular cryptocurrency right now, was the first application of blockchain and it offers many advantages to its users. Cryptocurrencies allow businesses to conduct transactions safely and more efficiently.  Misconceptions About Blockchain (What Blockchain is Not) To understand blockchain, you must first distinguish between the truths and myths surrounding this technology. Here are some of the common misconceptions about blockchain, you should know: Myth: Blockchain is a Replacement of a Transaction Processing System  Reality: You can use blockchain to replace a transaction processing system only in particular scenarios. It is not a replacement for a full-fledged transaction processing system.  Myth: Blockchain is Necessary Even if There is No Business Network Reality: If a business network doesn’t exist, you don’t need to implement blockchain technology.  Myth: Blockchain is a Product  Reality: Blockchain is not a product you can buy. The utility in the blockchain is because of the various applications you can build on top of it.  Myth: Blockchain is All About Bitcoins Or Blockchain is Bitcoins  Reality: Although bitcoin is the first application of blockchain, blockchain is not all about bitcoins. Bitcoin is a cryptocurrency based on blockchain where bitcoin is the digital token and blockchain is the ledger. You can have a blockchain without bitcoins but you can’t have bitcoins without blockchain.  What are Blockchain Variants? In this section of our blockchain tutorial, we’ll cover the different variants of blockchain technology.  Public Blockchain The distributed ledgers in the public blockchain are visible to every user. Here, every user is capable of modifying and verifying the blocks present on the blockchain. Some prominent examples of public blockchain are Ethereum, Factom, and Bitcoin.  Private Blockchain A private blockchain network usually belongs to a particular organization. Here, only several particular people of the organization can modify the transaction blocks. Still, any person can view the blocks but they can’t modify them. You’ll need permission from the particular users to modify the blocks present in such a network. Blockchain and Multichain are two prominent examples of the private blockchain.  Consortium Blockchain In a consortium blockchain, only a group of people or organizations can add and verify transaction blocks. The ledger in such a network is open to only a specific group. It is highly secure and is used by organizations in only particular sectors. Examples of consortium blockchain are R3, Hyperledger 1.0, and Ripple.  Hybrid Blockchain A fusion of public and private blockchains that allows for flexibility in data sharing. It permits select transactions to be public while maintaining the confidentiality of others. Hybrid blockchains are well-suited for applications necessitating both transparency and data privacy. What are Blockchain Philosophies? There are philosophies in the blockchain: Permissioned Blockchain Permissionless Blockchain Following are the differences between these two philosophies: Permissioned Blockchain In a permissioned blockchain, you have an access control layer to allow only a particular group of people to perform some actions. Such configuration keeps the transactional activities of the network’s users in check. Permissioned blockchains are popular among large companies and enterprises due to their high level of security.  For example, an IT-services provider might implement a permissioned blockchain network to record the sensitive information of its clients. Even though some third-parties might be involved in the transaction processes of such information, they shouldn’t have access to the sensitive information present in those transactions. A permissioned blockchain would ensure that the third-parties can’t access such information.  Permissionless Blockchain As the name suggests, a permissionless blockchain is the opposite of a permissioned blockchain. Unlike permissioned blockchains where only a few people have access to the blockchain, anyone can access the blockchain in a permissionless blockchain. Bitcoin and Ethereum are two notable examples of permissionless blockchains. Here, Proof of Work mining (PoW) is necessary and the hashing power determines the trust-level. What is Proof of Work? That’s what we’ll discuss in the next section. Comparison of Blockchain and Databases Blockchain: Blockchain is a distributed ledger technology that uses blocks to store information. It is built on a decentralised network in which all users validate and verify transactions. Each block contains hashed data from the previous block, ensuring cryptographic security. Blockchain offers advantages such as time reduction, unchangeable transactions, reliability, security, and decentralization. Databases: Databases are centralized systems managed by administrators. They store and manage data with defined access rights. Databases are efficient, easily maintainable, and support data sharing among authorized users. They provide features like redundancy control, data backup and recovery, and multiple user interfaces. Blockchain vs. Database: Decentralization: Blockchain is decentralized, while databases are centralized. Permission: Blockchain is permissionless, while databases require permission for access. Speed: Blockchain is slower, while databases are faster. Record History: Blockchain maintains a history of records and ownership, whereas databases do not. Confidentiality: Blockchain offers full confidentiality, while databases may not be fully confidential. Operations: Blockchain supports only insert operations, while databases support create, read, update, and delete operations. Robustness: Blockchain is considered fully robust, while databases may not be entirely robust. Disintermediation: Blockchain allows disintermediation, while databases do not. Writing Access: Anyone with proof of work can write on the blockchain, while databases restrict access to authorized entities. Recursion: Blockchain is not recursive, while databases allow repeating tasks on specific records. The choice between blockchain and databases is determined by the application’s particular requirements and the intended system features. If you want to learn more about blockchain, you may look at a thorough blockchain development tutorial to obtain a better knowledge of its ideas and implementation. Why is Blockchain so Secure? (PoW and Distributed P2P Network)  We already know that blockchain is a chain of blocks that contain transactional information. We also know that every block has a hash as its unique signature. However, hashes aren’t sufficient to keep the blockchain network secure.  Advanced computers can calculate hundreds of thousands of hashes within seconds and a hacker can modify a block without permission. Then, he or she can repeat the process to manipulate the rest of the blockchain.  However, blockchain has two solutions for tackling this problem and they are:  Proof of Work (PoW) Distributed P2P Network  Proof of Work Proof of Work is a computational problem that requires significant effort to solve. However, it takes very little time to verify the results of this problem in comparison to the time taken to solve it.  Thus, if a hacker wants to manipulate a blockchain, they will have to perform Proof of Work for one block, implement the modification and then redo the entire process for the succeeding blocks. Combined with hashing, Proof of Work makes blockchain a highly secure solution.  Distributed P2P Network  Every blockchain has a distributed peer-to-peer network. It doesn’t have a central authority to manage the chain, instead, it relies on the peer-to-peer network for this task.  When a user joins the blockchain network, they get a full copy of the blockchain and every computer in the network is called a node. When a new user creates a new block in the blockchain, it gets sent to all the users present on the network.  Now, every node (computer) must verify the block after which it can be added to the blockchain. All the nodes present in blockchain create a consensus about which blocs are valid and which aren’t. If a tampered block exists in the blockchain, then the nodes will reject the same. With the distributed P2P network, the hacker must now take control of more than 50% of the network after gaining access to a block and redoing the Proof of Work for every block to manipulate anything. Due to this, the blockchain becomes significantly secure.  How Do Blockchain Transactions Work? We have discussed that a blockchain stores transactional information, but how does a transaction take place in one? Here is how: A user would request a transaction related to the specific blockchain (cryptocurrency, records, contracts, etc.).  The requested transaction is sent to every node in the peer-to-peer network.  The nodes validate the transaction and the user’s status by using the required algorithms.  When the transaction is completed, a new block is added to the blockchain such that it is unalterable and permanent.  In conclusion, the steps of a blockchain transaction are: Request Broadcast Validation Addition This process is the same for any kind of blockchain no matter what application it’s used for. Whether you use the blockchain for a cryptocurrency or for keeping records, you’ll have to go through this exact process to add a new block into the blockchain. Learn more about how blockchain technology works. Why Do We use Blockchain? There are many advantages to using blockchain. Here are the most significant ones: Security With so many security provisions in place, blockchain is among the most secure technologies available to us. Tampering with it is nearly impossible.  Flexibility From healthcare to transport, you can use blockchain in any industry. All you need is a working knowledge of blockchain and the industry you want to implement it in.  Automation Most of the operations in a blockchain are done by software implementations. Such automation makes blockchain networks highly efficient.  Transparency Every change made in the blockchain is visible to all the users that have access to the same. This keeps things transparent and enhances the versatility of this technology.  Global Adaptation Organizations all across the globe are implementing or trying to implement blockchain in one way or another. It is a globally recognized and adopted technology and it’s gaining popularity.  Reliability Every interested party in a blockchain transaction is certified and verified. This removes the need for double records and makes the transaction process much more reliable.  Going Beyond the Blockchain Tutorial for Beginners Our blockchain tutorial for beginners covers the fundamentals of this topic. As you must have guessed by now, blockchain is a vast field with a lot of sub-sections and technicalities. Learning about all of them by yourself can be tricky.  The best way to learn blockchain is to get a blockchain course. With a course, you’ll be able to study from industry experts and learn in a step-by-step manner through the curriculum.  At upGrad, we offer the following two courses in blockchain technology: Executive PG Programme in Software Development- Specialisation in Blockchain Advanced certificate program in blockchain technology We offer both of these courses in partnership with IIIT-B.
