Mining our own Block

Overview

This repo depicts 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. Our goal is to successfully mine a block by including only the valid transactions, following the specific requirements outlined below.

Objective

Our primary objective is to write a script that processes a series of transactions, validates them, and then mines them into a block. The output of script should be a file named output.txt that follows a specific format.

Requirements

Input

• We have a folder named mempool containing several JSON files. Each file represents a transaction that includes all necessary information for validation.
• Among these transactions, some are invalid. The script should be able to discern valid transactions from invalid ones.

Output

The script must generate an output file named output.txt with the following structure:

• 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.

Execution

• We create a file named run.sh that contains the command to execute the script. This file should ideally contain a single command like python main.py or node index.js.
• The script should autonomously perform all tasks when run.sh is executed, without requiring any manual intervention.
