Benefits of Blockchain Technology and Related Examples
Published On : July 22, 2022 Category(s) : Blockchain
You’ve certainly heard the term ‘blockchain technology’ in the last several years, most likely about cryptocurrencies like Bitcoin. Blockchain appears to be a cliché, but only theoretically, as there is no significant meaning that a layperson can grasp. Blockchain is being used by Fortune 500 firms, government agencies, and charitable organizations to enhance old procedures and new business models. The usefulness of blockchain arises from its capacity to transfer data quickly and securely among entities without requiring anyone institution to bear responsibility for data security or transaction facilitation.
What is Blockchain and Why it is Hyped?
Blockchains, also known as Distributed Ledger Technologies (DLTs), make any digital asset’s history unalterable and transparent using cryptographic hashing and decentralization. To understand blockchain technology, you can use a Google Doc as an example. When we generate a document and share it with a group of individuals, we distribute it rather than copying or transferring it. This results in a decentralized distribution network where everyone has simultaneous access to the document. No one is locked out while waiting for changes from another party, and all changes to the document are logged in real-time, making them entirely transparent. Blockchain is a particularly promising and revolutionary technology because it reduces risk, eliminates fraud, and provides scalable transparency for many applications.
What is the Function of Blockchain?
Blocks, nodes, and miners are the three main components of the blockchain. Each block contains three fundamental elements:
The block’s data
A nonce is a 32-bit integer. When a block is constructed, the nonce is generated at random, and the block header hash is created. The hash is a 256-bit integer that is coupled with the nonce. It needs to begin with many zeros (i.e., be extremely small). A nonce creates the cryptographic hash when the first block in a chain is formed. Unless the block is mined, its data is considered signed and will always be linked to the nonce and hash.
Miners
Adding new blocks to a chain is done by miners using a technique called mining. Every block in a blockchain has its unique nonce and hash, but it also refers to the preceding block’s hash, making mining a block difficult, especially on big chains. Miners utilize specialized software to solve the exceedingly difficult arithmetic issue of generating an acceptable hash with a nonce. Miners are considered to have discovered the “golden nonce” when this occurs, and their block is added to the chain. In the event of any changes to a block later on in the chain, it is necessary to re-mine not only the affected block but also all the subsequent blocks in the chain. The miner is compensated monetarily when the block is successfully mined and acknowledged by all the nodes in the network.
Nodes
Decentralization is one of the essential principles in blockchain technology. A single computer or entity cannot own the chain. Instead, the nodes connecting to the chain form a distributed ledger. Any type of electronic equipment that saves copies of the blockchain and keeps the network running is called a node. Every node has its copy of the blockchain, and for the chain to be updated, trusted, and confirmed, the network must algorithmically approve every freshly mined block. Every action in the ledger can be easily reviewed and examined since blockchains are transparent. A unique alphanumeric identification number is assigned to each participant and used to track their transactions. The blockchain maintains integrity and builds confidence among users by combining public data with a system of checks and balances.

Blockchain Examples
Bitcoin and Ethereum are well-known blockchain examples. Anyone may connect to the blockchain and transact on it. All you’ll need is a computer, special mining software to connect to the blockchain, an internet connection, and a connection to a mining pool. You’ll pool your computer power with other miners to boost your odds of validating a block.
Wallets for the Blockchain
As the name indicates, Blockchain digital wallets allow users to keep their valuables on a blockchain. Wallets are pieces of blockchain-based software that may be downloaded independently or utilized as browser extensions, plugins, or hardware. Some wallets enable you to store several cryptocurrencies, while others only allow you to keep the asset for a single blockchain. Bitcoin.com and MyEtherWallet are two examples of wallets. Simply download the wallets, sign up, and receive a wallet address to which you may transmit and keep your digital assets. Offline transaction signing is possible with hardware wallets like Ledger.
Crypto-currencies on the Blockchain
Cryptocurrency is a digital asset and money that uses encryption to allow users on the blockchain network to own, store, trade, and exchange value safely. A central body does not control Bitcoin, Ethereum, and over 5000 other crypto tokens and currencies, unlike government-printed dollars, Euros, and Yuan.
Blockchain DAO
The most advanced smart contract is the Decentralized Autonomous Organization. It’s a computer-programmed organization that functions on the blockchain distributed network. Shareholders control the regulations, and the organization is unaffected by the central government. Members of the organization can freely and easily exchange value and develop and agree on rules. Including gadgets connecting with people, people communicating with people, and devices communicating with devices might be difficult.

The advantages of blockchain technology
Indeed, whether employing a public blockchain network or opting for private or permissioned blockchain-based applications, blockchain, and its properties may benefit enterprises. The top blockchain advantages, according to experts, are:
Enhanced privacy and security
Another major advantage of blockchain technology is its security. The increased security provided by blockchain is due to the way the technology operates: With end-to-end encryption, blockchain generates an incorruptible record of transactions, preventing fraud and illegal activity. Furthermore, blockchain data is distributed throughout a network of computers, making it nearly hard to attack (unlike conventional computer systems that store data together in servers). In addition, by anonymizing data and requiring permissions to limit access, blockchain can better handle privacy concerns than traditional computer systems.
Savings
The nature of blockchain can help businesses save money. Transaction processing becomes more efficient. It also simplifies reporting and auditing procedures while reducing manual duties like data aggregation and amendment. According to experts, the capacity of blockchain to streamline clearing and settlement translates directly into process cost reductions. More broadly, blockchain enables organizations to save money by removing the middlemen — suppliers and third-party providers — who have historically handled the work that blockchain can do.
Speed
Blockchain can conduct transactions substantially quicker than traditional methods since it eliminates middlemen and replaces remaining human procedures in transactions. In some circumstances, a transaction can be completed in seconds or less using blockchain technology. However, the speed with which a blockchain-based system can execute transactions is determined by several parameters, including the size of each data block and network traffic. However, experts have decided that when it comes to speed, blockchain outperforms conventional procedures and technology. Walmart utilized blockchain to track the origins of sliced mangoes in seconds, which took seven days before.
Transparency and traceability
Walmart’s usage of blockchain is about more than simply speed; it’s also about being able to track the origins of those mangoes and other items. This enables businesses like Walmart to better manage inventories, respond to issues or concerns, and verify the histories of their products. If a farm had to recall its product due to contamination, a retailer utilizing blockchain might identify and remove that farm’s produce while leaving the rest for sale. Experts say blockchain may assist monitor the origins of several things, including pharmaceuticals to ensure they’re genuine rather than counterfeit and organic foods to ensure they’re truly organic.
Innovation
Leaders from several sectors are experimenting with and deploying blockchain-based technologies to solve intractable issues and improve long-standing inefficient procedures. As an example of innovation, Field referenced the use of blockchain to authenticate the information on job candidates’ resumes. According to studies, a significant number of people fabricate their resumes, leaving hiring managers with the time-consuming duty of manually checking the material. However, pilot initiatives that allow participating colleges to publish data about their graduates and degrees conferred on the blockchain, which can subsequently be accessible by approved hiring managers, help solve both issues: getting to the truth and getting to the truth swiftly and efficiently.
Conclusion
Blockchain is being used in practically every aspect of business, including cryptocurrency, supply chain and logistics, intellectual property management, food safety, healthcare data management, fundraising and investment through security token offerings, and notary services. A corporation can choose to work on a public, private, or hybrid blockchain, then create its unique blockchain from scratch, tweak an existing application, or simply create an App or smart contract and begin moving its services to the blockchain one by one.
