Hi all 👋, welcome back to the very new and exciting blog 🥳. Have you ever heard of Blockchain and wondered what it is? If so, you're in the right place! In this blog post, we'll explore Blockchain in simple terms and dive into the technology behind it. So let's get started quickly 🤩.
But first, let me ask you this: have you ever sent money to someone overseas or made an online payment for a product or service? If you have, then you've probably encountered some challenges, such as delays, high fees, or even fraud. Blockchain was created to solve these problems and bring about a more secure, transparent, and efficient way of conducting transactions.
In this blog post, we'll take a closer look at how Blockchain works and its various use cases. By the end of it, you'll have a clear understanding of what Blockchain is and how it can benefit you. So, if you're ready to learn more about this revolutionary technology, let's dive in!
Blockchain Usecase 1:
One use case for blockchain technology is in supply chain management. A supply chain is the network of businesses and organizations involved in creating and delivering a product or service to customers. Supply chains can be complex and involve multiple parties, making it difficult to keep track of the flow of goods and ensure that all participants are acting honestly.
Using a blockchain, supply chain participants can create a shared, tamper-proof ledger of transactions that documents the movement of goods throughout the supply chain. Each time a product changes hands, a new block is added to the blockchain, and all participants in the supply chain can see the update in real time.
This transparency can help to reduce the risk of fraud and ensure that all parties are held accountable for their actions. For example, if a product is found to be defective, the blockchain can be used to trace it back to its source and determine where in the supply chain the problem occurred.
Additionally, smart contracts can be used to automate certain aspects of the supply chain, such as payments and delivery schedules, further streamlining the process and reducing the need for intermediaries.
Overall, blockchain technology has the potential to revolutionize supply chain management by increasing transparency, reducing the risk of fraud, and improving efficiency.
Blockchain Usecase 2:
One use case for blockchain technology in finance is in the area of cross-border payments. Traditional cross-border payments can be slow, expensive, and prone to errors. Banks and other financial institutions must rely on intermediaries to facilitate these transactions, which can add complexity and cost to the process.
By using a blockchain, cross-border payments can be made faster, cheaper, and with fewer intermediaries. With a blockchain-based payment system, all parties involved in the transaction can have access to the same ledger, which is updated in real-time as the transaction progresses. This can help to reduce the risk of errors and fraud, as all parties can see the transaction details and verify the authenticity of the transaction.
Additionally, blockchain-based payment systems can operate 24/7, allowing transactions to be processed at any time and reducing the time it takes to settle payments. This can be particularly beneficial for businesses that need to make international payments quickly.
Overall, blockchain technology has the potential to streamline cross-border payments by reducing the need for intermediaries, increasing transparency, and improving speed and efficiency.
Key Note:
Now, we have seen two use cases from different domains, but one thing is common in this, we are storing transactions (Tx) in the ledger (it is a key component of Blockchain where tx are stored in block format) and this transaction is immutable which ensure the transparency and security of Tx in the blockchain.
To understand this thing in a better way let's look into a few technical details.
Blockchain is a network in which nodes connect with each other running in a single network. Node is a key component of blockchain and it is distributed in different geolocation it is not owned by a single entity each node will be owned by a different entity which ensures a decentralized system, This node is responsible for storing all long chains of blocks which are linked together with cryptography. One key point to note here is that all nodes will hold the same set of blocks which ensures security and traceability.
The hierarchy of the blockchain component is like this blockchain network -> nodes -> a number of blocks -> each block stores transaction details. -> Tx is generated by the user.
Example of a transaction - It is a set of records that has the details of activities, like “A sending 900$ to B”, “XYZ received item successfully at this date and time” and “ABC product has dispatched from Mumbai at this date and time”. These are simple examples of Transaction(Tx).
Block structure: block is the fundamental unit of the blockchain network which is connected with other blocks cryptographically. Each block contains # hash of the block, #hash of the previous Block hash, and Merkle root - all transaction is hashed in a single hash code that is nothing but Merkle root and Nonce - it is used to create a complexity of block generation process.
Now, it's good time to derive a definition.
A blockchain is a digital ledger of transactions that is decentralized and secure. It uses cryptography to validate and record transactions in a way that is resistant to modification or tampering. The ledger is maintained by a network of computers, or nodes, that work together to verify transactions and ensure the system's integrity. Each block in the chain contains a unique code, or hash, that links it to the previous block, creating an unbreakable chain of data. This makes blockchain an effective way to track and verify transactions without the need for intermediaries, like banks or governments.
