hello learners,
you already feel the hype of crypto,NFT and web 2.0 that can change the system of internet in near future but do you guys know the heart core technology behind these amazing application's .the answer is blockchain let understand some basics of blockchain through this article.

DEFINITION

let understand the definition in simple words . blockchain consist of two words block and chain.

block

blockchain is a database that collects the information and put it in into a block.

chain

after collecting the information in the form of block they make a chain.

blockchain is a database that collects the information and put in into a block and these blocks make chain that called a blockchain .

there is a quick question that hits your mind that "we already have DBMS and RDMS concept for database and have powerful language's like mysql ,nosql to store data in a database on a large scale then why we need a new database like blockchain.

DIFFERENCE BETWEEN BLOCKCHAIN DATABASE AND OTHER DATABASE

the key difference between the blockchain database are other database:

1. blockchain is a decentralized network while other database network are centralized .

2. blockchain distribute the data and save the data over 1000 computer over the network while other database are save the data on the server only.

3. In blockchain the transaction history is immutable while in other databases the transaction data can be alter by the company and the user.

FEATURES OF BLOCKCHAIN

1. IMMUTABLITY

   this is the key feature of the blockchain .Immutablity means the data in the blockchain cannot be alter or changed by the company or third ones the transaction is done .

2. DECENTRALIZED

   blockchain is decentralized means no particular goverment,group of peoples , organization own the blockchain there is only receiver and sender in the blockchain .

3. ADVANCE SECURITY

   blockchain network cannot be easily hack because it contain a lot of cryptography layers for the users to safety against hackers and other security issues.

4. FASTER SETTLEMENT

   In banking ,once you pay the account sometime the payment is not updated by the bank , sometime the server are not working and many other conditions that slow down the processes of the bank but the blockchain is fast in these scenario and settle the transaction in very fast and easy way.

REAL WORLD APPLICATIONS FOR BLOCKCHAIN

1. digital payment
2. protection of loyalty and copyright
3. unchangeable data backup
4. digital ID's
5. supply chain management
