+# Proof of Work Script
+
+This bash script implements a Proof of Work (PoW) algorithm using the Argon2 hashing function. It is designed to solve a mining challenge based on given parameters, making it suitable for educational purposes or testing PoW implementations.

+
+## Features
+
+- Checks for required utilities (`argon2`, `xxd`, `bc`).
+- Accepts a challenge code as input, either via command line or prompt.
+- Iteratively generates and hashes candidate passwords until a valid solution is found.
+- Displays the solution once it meets the required difficulty.
+
+## Requirements
+
+Ensure the following utilities are installed on your system:
+
+- `argon2`: A secure hashing algorithm for password hashing.
+- `xxd`: A tool for creating a hex dump from a binary file and vice versa.
+- `bc`: An arbitrary precision calculator language.
+
+You can install these utilities on Debian/Ubuntu-based systems with:
+
+```bash
+sudo apt-get install argon2 xxd bc
+```
+```bash
+git clone https://github.com/TiredFromTelehack/proof-of-work.git
+cd proof-of-work
+```
+```bash
+chmod +x proof_of_work.sh
+```
+```bash
+./proof_of_work.sh "262144:1:SALTe7e590c2f902:1500"
+```
