The use of cryptography is commonplace in blockchain technology. This is used to ensure that transactions are carried out securely while protecting all information. Cryptography is a method of hiding and revealing (also known as encryption and decryption) information using numbers and mathematics. This means that the information can only be seen by the intended recipient and no one else. You can also get more info about blockchain through the internet.

This method takes unencrypted data and encrypts it with a mathematical algorithm. The use of encryption in blockchains serves two main purposes:
Blockchain technology uses basic encryption for data that is more secure and cannot be tampered with in the following ways:
Digital signature
In blockchain technology, public key cryptography makes digital signatures that ensure the integrity of the displayed data by combining the user's authorized key with the data they wish to sign using a mathematical algorithm.
Blockchain uses signatures to sign transactions. A signature is used to prove that a particular user has an entry that matches a specific hash.
Since the actual data itself is part of the digital signature, editing even the smallest aspect of the data will redraw the entire signature, rendering it incorrect and out of date. The use of digital signatures in blockchain technology can ensure that all data stored in it is true, accurate and unimpeded. Digital signatures provide consistency to the data stored on the blockchain.
