Re: Understanding the Blockchain nasscom The Official Community of Indian IT Industry


This virtual is open to everyone and anybody can invest in Bitcoin. Even though the concept of blockchain was first introduced as a research project in 1991, it became famous only after Satoshi Nakamoto published the Bitcoin ‘whitepaper’ in 2008. And the creation of cryptocurrencies, decentralized finance , and smart contracts has skyrocketed as a fundamental pillar of blockchain technology. In simple terms, a blockchain is a digital ledger or a tracking sheet that stores the list of transactions across multiple computers in a network. Now, you might ask how it is different from the bank’s ledger or track sheet?


Issuance of these certificates can be regulated and automated with the help of blockchain networks by enhancing the user’s security confidentially. It helps in reducing large-scale data breaches and prevents cyber threats. Non-fungible tokens are another great example of modern Blockchain applications. These are digitally generated and verified tokens that are usually used in transactions among users in the form of digital currencies.

Nodes on the network compete to solve complex mathematical problems to add the next block to the chain. The first node to solve the problem is rewarded with a certain amount of cryptocurrency, which incentivizes miners to participate in the network. A blockchain network consists of nodes, which are computers connected to the network. Each node has a copy of the entire blockchain ledger, which is constantly updated as new transactions are added to the network. In almost all instances, a company’s daily focus is on delivering product to its customers.

The second floor of the house is Layer 2, which has certain benefits but is not essential for a blockchain to function. At Layer 1, each blockchain can operate independently of every other chain. At Layer 1, the decentralization, open-source, and immutability of a blockchain begin to manifest themselves completely. Just write the bank account number and sign in the application form to authorise your bank to make payment in case of allotment.

Smart contracts are computer codes and are executed by checking some predefined conditions. After the Smart contracts have evolved, many applications of blockchain technology also evolved like decentralized web applications, Android, and PC applications. Let us now understand how Walmart uses Blockchain technology to provide better services to its users. Walmart was facing problems in delivering quality products to its customers. They were facing high return rates and large amounts of refunds due to their product’s bad quality. They were unable to determine the point of failure in their supply chain which started from farm, storage, transportation, processing and all the way to the distribution center.

Creating visibility across the end-to-end supply chain requires a platform where all independent actors participate and download/upload the specific information that they control. The source for the information that enables collaboration and integration for the extended supply chain is the blockchain. But, for a company, its interaction with the blockchain will be limited to “writing to” or “retrieving from” the platform. At the point where information is required by/from other actors in the supply chain, the organization may be required to interact with a blockchain. The year 2023 is seeing the trend of enterprise operations that are relying on blockchain technology.

Blockchain Technology can be used in multiple use cases in the healthcare industry. It is used to store and maintain confidential health information and track patients’ progress and treatment details. The process of solving these complex mathematical problems is called “Proof of Work”. Blockchain can simply be defined as a collection of records linked with each other, strongly resistant to alteration and protected using Cryptography.

The larger the transaction data size, the longer and more energy it will take for miners to validate the data. Just like you need a bank account to trade stocks, it all starts with setting up a bank account and verifying your details. After verifying the account, the user can add a number of payment methods including credit and debit cards. Once you have successfully created your account, you can conveniently buy and store your cryptocurrency on the platform and conduct instant transfers. The cryptocurrency is an attractive and potentially profitable investment which provides a feasible method of issuing and tracking ownership of each unit. Bitcoin is the ownership of an entity which can be transferred to others at will.

So, for a company in some industries the blockchain represents a powerful tool. The blockchain provides visibility, at a specific moment in time, to an action that occurred in its extended supply chain . For the average company access to that « moment in time » information is only important when there is a unique event that demands historical and extended supply chain information. The blockchain is a powerful tool to capture incredible amounts of data.

The current blockchain networks cannot process large amounts of transactions quickly. This is because blockchain networks are decentralized, and each node needs to process and verify each transaction. Instead of having a single, centralized authority managing all transactions, the blockchain distributes this workload across a network of computers.

A system with so many capabilities will also have some weaknesses and that is why Blockchain application testing is important to remove them and make it more reliable. Hyperledger is an open-source tool that can be used to model and test a blockchain network with a help of some minimal tools like Docker and a browser. It helps in developing blockchain applications with the help of a modelling language, a UI , a Command-line Interface. It allows performing automated system tests, interactive testing, and automated unit testing. Cloud computing is another massively evolving domain of Computer Science. In cloud computing, billions of data are stored in servers by cloud providers.

Moreover, any hacker will not be able to alter the date in the blockchain because each user has a copy of the ledger and the date in the blocks are encrypted by complex algorithms. In early 2017, the United Nations world food program started a humanitarian aid mission. The project intends to use blockchain technology and send beneficiaries money, food, and all types of transactions registered on a blockchain to ensure greater transparency and security. There is lots of press focused on the blockchain and its capabilities. Much of the reporting is very informative, but the way it is presented is often bordering on “hype”. It is important for management to understand the position the blockchain provides as a tool and its potential positive impact on daily operations.

Blockchain-Based Voting System

For example, Bitcoin uses the SHA256 algorithm, Ethereum uses ETHASH. These types of transactions are taking place across the world and are added block by block. This is to inform that, many instances were reported by general public where fraudsters are cheating general public by misusing our brand name Motilal Oswal. The fraudsters are luring the general public to transfer them money by falsely committing attractive brokerage / investment schemes of share market and/or Mutual Funds and/or personal loan facilities. Though we have filed complaint with police for the safety of your money we request you to not fall prey to such fraudsters.

  • Is that it can also be used at voting platforms and to manage titles and deeds.
  • It helps in reducing large-scale data breaches and prevents cyber threats.
  • The larger the transaction data size, the longer and more energy it will take for miners to validate the data.
  • Populus has ethereum testing functionality, with the help of a specific set of features for the deployment of test contracts.
  • Using blockchain, smart contracts can allow customers and insurers to manage claims transparently and securely.

The Bitcoin Blockchain is a very simple database or ledger that comprises of Bitcoin transaction records. The beauty of the Blockchain technology is that the database is distributed across a P2P network and there is no central authority that regulates it. Thus it overcomes one of the principal concerns over existing currency creating structures which are too dependent on the decisions of a central bank. Therefore, all the network participants must agree on the validity of the transaction before entering into it.

Blockchain is active round the clock processing the transactions way more efficiently. Security – Blockchain technology is highly secure, with each transaction verified and recorded on multiple nodes on the network. Blockchains capture incredible amounts of detail about a product/SKU at a point and string that information together to form a linear presentation of the lifecycle of that product/SKU. But, they do not present a comprehensive picture of the aggregated position of the product/SKU to support inventory optimization across the supply chain network. For day-to-day supply chain operations the blockchain will have limited, if any, impact. In fact, I would go so far as to say that in many cases, organizations will find that it is a net cost and of limited benefit.

Battle of the Blockchain: Understanding XRP and its Potential Compared to Dogetti and Ethereum

The process involves converting legible information into an almost uncrackable code, to track purchases and transfers and that’s how the transactions are secured. The first cryptocurrency Bitcoin was created in 2009 and is still the best known digital currency. The potential of blockchain technology is immense, and its applications are only beginning to be explored. As the technology matures, more innovative use cases will emerge, and the potential of blockchain technology will be fully realized. Blockchain technology could become a cornerstone of our digital economy with the right investment and adoption. The blockchain comprises a series of blocks containing a timestamp and a link to the previous block.

It is better to explore and get an exact idea of these platforms before choosing an option. It is helpful in the verification and traceability of transactions that are multi-step. It can be useful to provide secure transactions, reduce compliance costs, and speed up the data transfer process. Every time a transaction is made all the n people write it in their books, and no person controls the overall representation of the transactions. This framework is based on Java and allows testers to interact with the real BTC network and test transactions.

Blockchain and the cryptocurrency

Transparency – Blockchain technology provides transparency, allowing users to see all transactions on the network. Healthcare – Blockchain technology can be used to securely store and share medical records, improving patient privacy and data security. Supply chain management – Blockchain can be used to track products throughout the supply chain, providing transparency and ensuring that products are genuine. When a user initiates a transaction on the blockchain, it is broadcasted to all nodes on the network. The nodes then verify the transaction to ensure that it is valid, which involves checking that the user has the required funds and that the transaction has not already been recorded on the blockchain. Different blockchains provide different functions and have their own advantages and drawbacks.

It can provide better transparency throughout the selling and buying process. With its immutable nature, blockchain is well suited to perform tasks such as real-time tracking of goods as they move and change hands throughout the supply chain. Since blockchain does not allow any third party to approve transactions automatically, the processing costs also come down. Cryptocurrencies using blockchain can be sent across the globe more quickly and cheaply, unlike the traditional banking systems.

  • They don’t add what c said on the consensus protocol, where voting is done on the basis of validity of transaction in the blockchain.
  • The job of miners is extremely complex and also very resource intensive.
  • Originally devised for the digital currency, Bitcoin, the tech community is now growing and they are appearing in a variety of commercial applications today.
  • The main goal is to implement a blockchain-based system that can make Dubai ‘the happiest city in the world’.
  • Read ahead to gain knowledge about blockchain technology and its basics.
  • You will also learn about oracles, smart contracts, and how to ensure the security of your blockchain.

The computational power required to solve the puzzle increases as more nodes join the network, making it difficult for any single node to control the network. A blockchain consensus mechanism is a process by which a distributed network of nodes agree on the validity of transactions and the order in which they are added to the blockchain. The consensus mechanism ensures that the network remains secure, transparent, and decentralized. There are several consensus mechanisms in use today, but two of the most commonly used ones are proof-of-work and proof-of-stake. In financial services like stock markets, it takes at least 2-3 business days to buy and sell stocks and convert the money to receive as liquid cash.

The only difference is that internet content is not entirely certified but all records on Blockchain have to go through a rigorous process of review. Apart from legal documentation and medical records maintenance, Blockchain was also used to create a crypto currency. What businesses are now focusing on is how Blockchain technology can be leveraged in a variety of different areas including the complex world of global financial markets. You have often heard about blockchain technologies and cryptocurrencies. Bitcoin is probably the first most visible application of blockchain and the first cryptocurrency to arrive. Having proved the feasibility of cryptographic-backed money supply, Bitcoin is the first alternative to fiat currencies.
