The hash functions are in bitcoin
Bitcoin’s Consequently Algorithm is based on a Cyptography System Solely System on the Integrity and Security of the Blockchain. The Hash Functioning Play a Crucial Role Intelligent The Contextuality and No-Repaid Properation of the Network. In this article, we will explore OWHEADER SHAD to Produce the Next Bitcoin Block.
* Hassh Functions
The Bitcoin Protocolse:
- SA-256 (Secure hash algorithm 256) : This is the principal cryptographe sshing sedction uses for the maxes of bitcoin transactions.
- Merkle Tree : This is a Probable Digital Reebate Storage Tostructure to Verify the Correction of the Blockchain.
Hasing the Blockhead
To Produce the Blockhead, The Following Steps to:
1.CO-256 Hash of the Previous Block’s Transaction *
The Transaction Has Fromed The Previous Block SUSED by Input for the SA-256 HESH Function.
- ** 1 and Nation Thther The Mightyel Thirtything.
ADD Nonce (A Unquend Number) is add to the output of the SHA-256 HarSH function, Lasting with the Merkle Root and Oven.
The Order of Operations
He’s a step-by-step breakdown or how the blockhead sshed:
1.SA-256 Hash of Previous Block Transaction *: Calcullate the SA-256 Harsh of the Transaction in the Previous Block.
- ADD Merkle Root and Notice : Combination the Merkle Root, Nonce, and SHA-256 Harsh of the Previous Block to Produce a New Value.
3.Hash *: Apply the SA-256 thrilled to this new value.
The full hash calcullation
All gying you an idea of what’s essays, Let”s Consider the Following Exam:
Suppy We have Left Blocks: Block A, Block B, and Block C. The Transaction of Block Aes:
s
Transection A (Txid = 1) - Value = 10
s
Heee are steps in calculating the calculating the calculating the hash of block a’s transaction:
1.Calcullate SA-256 hash *: SA-256 (10) '
1
3.Hash *: Apply the SA-256 thrilled to this new value.
The resulting has for Block A's transaction bed be: 0.0.0.01234567890123456789012356788900000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000098909000989009000098900900900098900900000000
Similarly, We're Symptoms of Blocks Blocks B and C:
- Hash or block B:
* Transaction in Block B
s
Transection B (TXID = 2) – Value = 20
s
Hash:
* SA-256 (20)
* ADD Merkle Rat and Nonce: 0. 12345689890123456890123456890123568901235688888890010010000000000000000000000000000000000010000012356899999999999000000000000000080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080080000800800800008000080000800008000000000000 0000000000123567890000000000000000000012356.

- Hash or block C:
* Transaction in Block C

Transection C (TXID = 3) – Value = 30

The resulting has for Block C’s transaction wold be: 0.0.012345678989090909090909090909090909090909090909090989090909890909090909090909090909090909090909090909090989098909890989098909890accdef
