What is Blockchain: Features and Use Case

What is Blockchain?

Blockchain is a list of records called blocks that store data publicly and in chronological order. The information is encrypted using cryptography to ensure that the privacy of the user is not compromised and data cannot be altered.


Information on a Blockchain network is not controlled by a centralized authority, unlike modern financial institutions. The participants of the network maintain the data, and they hold the democratic authority to approve any transaction which can happen on a Blockchain network. Therefore, a typical Blockchain network is a public Blockchain.


As long as you have access to the network, you have access to the data within the Blockchain. If you are a participant in the Blockchain network, you will have the same copy of the ledger, which all other participants have. Even if one node or data on one particular participant's computer gets corrupted, the other participants will be alerted immediately, and they can rectify it as soon as possible.





Why Do Transactions Fail?


Imagine two people are making a money transaction. Now, assuming the sender has properly sent the money from his bank, there’s no chance the transaction will fail, right?


Several things can go wrong, including: 


  • Something could have gone wrong at the bank (such as a technical issue)
  • The sender’s account could have been hacked
  • The transfer limits of the day could have been exceeded
  • Debited from one account, never credited on the other side
  • Issues with data


However, none of these problems apply to cryptocurrencies. First, let’s have a look at what cryptocurrencies are.


What is a cryptocurrency?


A cryptocurrency is a form of digital currency that can be used to verify the transfer of assets, control the addition of new units, and secure financial transactions using cryptography.

One of the cryptocurrencies’ most important advantages over normal (fiat) currencies is that they are not controlled by any central authority. Without a central point of failure or a “vault,” the funds cannot be hacked or stolen.


As an analogy, think of the popular Microsoft Excel spreadsheet program. You can make changes to the data on your own that may differ from earlier versions of the spreadsheet that are shared with others. But if you make changes to a Google Sheets document, on the other hand, those changes also show up in every other shared copy. Similarly, the shared and distributed nature of cryptocurrencies keeps everyone on the same page.


Therefore, the transparency and distributed nature of blockchain technology are what make cryptocurrencies (at least those that use the blockchain) secure.

Smart contract in Blockchain

A technology that will change the way you trust through an automated contract management system. A smart contract is an agreement between two parties in the form of computer code. They run on the blockchain, so they are stored on a public database and cannot be changed. The transactions that happen in a smart contract processed by the blockchain means they can be sent automatically without a third party. In 1994, Nick Szabo (a cryptographer), came up with the idea of being able to record contracts in the form of computer code. This contract would be activated automatically when certain conditions are met. This idea could potentially remove the need for trusted third-party companies (such as banks). But why? The answer is simple — because you no longer need a trusted third party when you make a transaction. Instead, the contracts (or transactions) are self-executed on a trusted network that is completely controlled by computers. Cool idea, right? Szabo worked on this idea for many y...
