What Is Blockchain: Where Is It Used?


Blockchain is a database system that is distributed and shared by the computer nodes. It stores data in an electronic form. This database system provides a secure record of the transaction. However, it varies from the typical database by a few differences.

One such key difference is its structure. It collects information in blocks and these blocks have storage capacities. When these blocks are closed and attached to each other, they form a chain-type structure known as the blockchain.

Features of Blockchain:

It is not new in the market. It’s been a while since this technology emerged and still, it is in the spotlight. It gained fame through bitcoin and it isn’t just a backup network for cryptocurrencies. It provides immutability, which means that something cannot be changed.

This feature ensures that the technology cannot alter and will remain the same. To further learn in-depth and master the skills, one can visit Blockchain Online Training. Here are some of the features of this database system due to which it has gained so much popularity.

  1. As every node has a copy of the digital ledger, it is transparent and cannot be corrupted.
  2. It is a decentralized technology and it is maintained by a group of nodes rather than a governing body.
  3. It provides multiple layers of security.
  4. Every block comes with a consensus that assists the network in making decisions.
  5. It transfers money faster and offers a quicker settlement.

Is Blockchain Secure:

Blockchain has gathered fame as powerful security for protecting the necessary information. In addition, it provides decentralized security and protection in every aspect. To begin with, this database stores every new block in chronological order. In other words, they come to the last of a blockchain.

None of the technology is ever immune to hacking, however, blockchain assures a better and stronger line of defense. Bitcoin and Ethereum are some of the largest and securest network examples. These database systems work by storing the data using complicated math and distinct software rules, therefore hacking becomes a challenge for the hackers.

Hash acts as a fingerprint. These hashes act like a link between the blockchain in such a way that each block consists of the previous block’s unique hash. So, in order to hack it, you have to calculate the hash not only for a single block but for all the blocks previous to it. This should be done faster than the system adds a new block. Therefore, this makes Blockchain hard to crack and tamperproof.

Career Options in Blockchain:

Blockchain provides tremendous job opportunities and is surely a good career option. A blockchain consultant is one of the highest-paying jobs in the world. Therefore, this database has emerged as an alternative technology worldwide and is demanded by all enterprises.
