Question

In your own words Write a short report how the blockchain Hashes digests information. Go through the process on how the algorithm works

Answer 1

Blockchain Hash Function
A hash function takes an enter string (numbers, alphabets, media files) of any length and transforms it into a set period. The constant bit length can vary (like 32-bit or 64-bit or 128-bit or 256-bit) depending on the hash feature that is being used. The constant-length output is known as a hash. This hash is likewise the cryptographic byproduct of a hash set of rules. We can recognize it from the subsequent diagram.

Blockchain Hash Function
The hash set of rules has certain particular residences:
It produces a unique output (or hash). It is a one-way characteristic.
In the context of cryptocurrencies like Bitcoin, the blockchain uses this cryptographic hash function's properties in its consensus mechanism. A cryptographic hash is a digest or digital fingerprints of a certain amount of facts. In cryptographic hash capabilities, the transactions are taken as an enter and run thru a hashing algorithm which offers an output of a hard and fast size.
SHA-256
A Bitcoin's blockchain uses SHA-256 (Secure Hash Algorithm) hashing set of rules. In 2001, SHA-256 Hashing algorithm became developed with the aid of the National Security Agency (NSA) in the USA.
How does the hashing method works? For this hash characteristic, we're going to use a application developed by Anders Brownworth. This program can be found in the below link. Anders Brownworth Hash Program: https://anders.Com/blockchain/hash.Html Blockchain Hash Function If we type any character in the facts section, we will have a look at its corresponding cryptographic hash inside the hash section. For example: We have type in facts section: This is a top notch tutorial. It will generate the corresponding Hash: 759831720aa978c890b11f62ae49d2417f600f26aaa51b3291a8d21a4216582a Blockchain Hash Function
Now if we exchange the text: "This is a notable tutorial." To "this is a amazing tutorial." You will discover the corresponding Hash: 4bc35380792eb7884df411ade1fa5fc3e82ab2da76f76dc83e1baecf48d60018
In the above, you may see that we have changed simplest the first character case sentence from capital "T" to small "t" and it's going to trade the entire Hash value. Note: If we write the equal textual content again in a records section, it's going to constantly deliver the same output. It is due to the fact you are developing a message digest of that one's specific quantity of records. Since the Hash characteristic is a one-manner feature, there's no manner to get back entire textual content from the generated hash. This is special from traditional cryptographic capabilities like encryption where you could encrypt something the usage of the important thing and by using the usage of decryption, you can decrypt the message to its unique form.
