Blockchain is the technology that covers digital currency (like Bitcoin, Litecoin, Ethereum, and others). This technology allows digital information to be distributed and decentralized, but can’t be manipulated. That means each piece of data can only have one owner but many holders of the same data.
Blockchain is a block is a record of new transactions. When a block is completed, it’s added to the chain. So, Blockchain is a way to save data and make it immutable. That sounds great, but the big question, of course, is: how does that work? The work is quite complex, you can check Wikipedia for this.
Need for Blockchain:
- Blockchain will enhance the reach of a businesses
- It will ensure swift transactions
- Blockchain highly restricts fraud
- Blockchain is reliable and transparent
- Immutability
- It is Cost-effective
The distributed ledger technology used in blockchain offers multiple benefits to businesses that make a difference when implementing a solution that requires a high degree of trust for business transactions.
Blockchain cannot process transactions faster because it doesn’t use a centralized infrastructure and also because it uses 256-bit encryption. The distributed nature of blockchain provides a huge level of trust. The unchangeable property of blockchain and its public availability among its users, whether in a public ledger or a private one, provides transparency. Any user of the system can query transactions on a real-time basis.
In short, by adopting Blockchain people across the world can say goodbye to the middleman, and dependence on banks, legal agencies, and hackers.
Uses of Blockchain Technology:
- Payments: Cross-Border Payments
- Blockchain Internet-of-Things (IoT)

Future of Blockchain:
The future of finance could be dominated by blockchain technologies. The future of security is in the blockchain because the current methods of keeping the data are not reliable enough. Blockchain is the revolutionary tech of the future, for future security aspirants, it will be the best for them to understand the working of blockchain. Some Sector that is affected by Blockchain:
- Financial Services: It is an area that seems to be affected much as the blockchain gives secure payment facilities for a particular transaction, as it removes third-person dependency.
- Real-estate: Real estate transactions are expensive and lots of paperwork is to be required. Blockchain finds its potential to remove the middleman, making the process, more transparent and securable.
- Legal Fields: Blockchain uses smart contracts to validate the ownership of the documents, as well as to authenticate and secure the criminal justice system.
