What is Blockchain?
A “blockchain” is basically a technique to store information or to store data in a decentralized manner. A centralized authority does not have access to control the complete set of data and information in a decentralized system. Bitcoin and any other cryptocurrencies do not control by any central authority or agencies as they are all decentralized.
Blockchain is the technology behind Bitcoin’s decentralization. The information is stored in different ways on blockchain technology. Similarly, the information on a blockchain is organized in the form of blocks. Each block consists of three primary components. The block is entered to store any data or information as per the user wishes to start with.
Second, each block has its own unique fingerprint, referred to as a hash. This is a way that a block is different from other blocks. Each brick has a unique fingerprint. Finally, each of these blocks saves the fingerprint of the previous block. A blockchain is a digital ledger.
What about Privacy?
In fact, the information stored in the blockchain is not only secure but also private. Since every machine in the network has its own private key and public address, this is possible.
For example, consider giving them your email address and password. You input your email ID and password to log into your email account, and only you get access to it.
Blockchain may be about the same technology. When you share your email address with others, though, you’re sharing your public address rather than your private key. This public address, on the other hand, is a random collection of numbers and digits.
What do Miners Get?
There has to be some sort of incentive. So there are benefits. This reward is in the form of Bitcoins in the case of the Bitcoin Blockchain.
Every machine receives some bitcoin which is linked to the bitcoin network and mining process. Any computer that falsely verifies something is also punished. There is also a monetary penalty. As a result, the entire decentralized network is based on reward and punishment.
BlockChain: Real-Life Implementation
We’ll look at some additional examples of how the real world is using blockchain. The fact that it has already been utilized for elections will be the most stunning and exciting fact. Sierra Leone is a country in Africa. Blockchain technology was in use for voting during the election.
Many experts argue that employing Blockchain technology for elections and voting is inappropriate. According to experts, the disadvantages outweigh the benefits. The chances of hacking are increasing day by day.
Although it is tough to hack the blockchain, it may not be as difficult to hack individual phones. Attacks can also be carried out when the network is turned down. As a result, this is not a simple answer, but rather a topic for discussion.
However, there are certainly other industries where blockchain is unquestionably beneficial. And it’s already being used in that location. As in the healthcare industry, medical data can be stored on the blockchain.
As a result, the patient’s medical data in a database is not in a central record. A doctor can’t see them unless he or she has a valid reason. Patients will be able to relax in a more private environment. In addition, the data will be more accessible.
The Future of Blockchain
The same applications you use today, whether it’s social media, censorship or copyright issues, video upload, streaming platforms, or any other platform you can think of, will all have to use Blockchains in the next 10-15 years because users today trust and belief in companies that are transparent with their work, not those that hide from the public eye and modify their processes.
As a result, some feel that blockchains have the potential to alter the world. Like how the Internet altered the course of history, we can no longer envisage a world without the internet. People also believe that it will be difficult to imagine living without blockchain technology in the near future.
