Hash Functions -Chapter 4- Learning Basics of Blockchain [Beginners Guide]

in #bitcoin7 years ago

Hello everyone, Happy New Year to all of you! I wish you a lot of luck,health,wealth and prosperity in your life and for me too. lol! Today we are going to talk about Hash Functions and how hash function is the key component of blocks of Block Chain! So lets start!

Hash Funtions

We have learned about the role of miners but miner and whole block chain will remain incomplete with Cryptography or simply called as Hash Function. Hash can be defined as the digest outcome of any given data and when we bind this with a method then it becomes Hash Function. Hash function generates an alphanumeric outcome which may be of 32 characters ,act as a unique identification like we have identity cards. Every inputs has its own unique hash just like a fingerprint which can't be duplicated.

Why we use hash?

The most important thing to note about Hash Technology is the adaptability,uniqueness and speed! Hash can be calculated for Any Size of Data no matter how much of data is stored or inputed for calculation of hash. Hash cannot be Reversed.

Hash is One way function

Hash is one way function ,but how?
We use encrypting or decrypting technology. It means and encrypted data can be decrypted but in hash function,you can't reverse the hash or decrypt to see the input data. That is why it is called as one way function. Hash cannot be reversed instead every hash key has its own unique data on every computer. It means if hash key of Data "ABC" is "af34g" than it will remain same on every computer.

Hash is core but not everything!

Hash is core component but every block of bitcoin block chain is made up of three main components....

  1. Nonce
  2. Hash Value
  3. Block validation

It's New year... So just go outside and enjoy....

That's all in this post.... lets enjoy New year!
