Mine your first block

Overview

the simulation of mining process of a block, which includes validating and including transactions from a given set of transactions. The repository contains a folder mempool which contains JSON files. These files represent individual transactions, some of which may be invalid. we select some of the transaction to the mempool where successfully mine a block by including only the valid transactions,

Objective

The output of your script should be a file named output.txt that follows a specific format. where the ouptut.txt contain the data which one block have like blockhash and target difficulty and the list of transaction , merkle root .

Requirements

Input

Each in mempool file represents a transaction that includes all necessary information for validation.

  • Among these transactions, some are invalid. from this list of mempool you have to select some of the trnsaction which you think you have to mine

Output

output file named is with the structure like

  • First line: The block header.
  • Second line: The serialized coinbase transaction.
  • Following lines: The transaction IDs (txids) of the transactions mined in the block, in order. The first txid should be that of the coinbase transaction

Difficulty Target

The difficulty target is 0000ffff00000000000000000000000000000000000000000000000000000000. This is the value that the block hash must be less than for the block to be successfully mined.

This part is when you have to run minning algorithim from the terminal .

Execution

  • A run.sh file is Create that contains the command to execute your script. This file contain a single command which run the all the needed file to run the mining alogrithim without anyother manulally interaction .

WHAT I DONT DO :

  • Do Not Use Bitcoin Libraries for Transaction Validation: You must not use any Bitcoin-specific libraries or frameworks that automate transaction validation processes. The intent of this challenge is for you to understand and implement the validation logic manually.

  • Permissible Libraries: The use of standard cryptographic libraries, such as secp256k1 for elliptic curve cryptography, and standard hashing libraries (e.g., for SHA-256) is allowed and encouraged. These libraries are essential for implementing the cryptographic underpinnings of bitcoin without reinventing the wheel.

  • Implement the Mining Algorithm : To implement the mining algorithm on my own. in which creating a way to correctly form a block header, calculate the hash, and meet the challenge of finding a hash below a certain target.
