Blockchain is a specific type of database. It differs from a typical database in the way it stores information; blockchains store data in blocks that are then chained together. As new data comes in it is entered into a fresh block.
Each block contains its own digital fingerprint/signature called Hash, the hash of the previous block, a timestamp and the data of the transaction made, making it more secure towards any kind of data breach.

- Creating Blocks
- Generating Hashes
-
Blokchain is a distributed network of systems. Therefore, data breaches are very difficult to be carried out.
-
Since, Blockchain generated hashes of each block, therefore, it is very difficult to carry out malicious attacks with the data stored in them.
-
Data Tampering will change the hash of each block which will make the blockchain invalid (tampering involves the malicious modification of data by an unauthorised user. Data exists in two states; either in transit or stored. In both cases, data. could be intercepted and tampered)
