This repository contains the Computer Assignments from the "Crypto Currency" course at the University of Tehran in the Spring of 2024.

In this assignment, we used python cryptography library to encrypt and decrypt a message with symmetric and asymmetric encryption algorithms. We used AES and RSA algorithms for symmetric and asymmetric encryption, respectively. We also used the RSA algorithm for digital signature.

In this assignment, using python libraries we created some transactions in testnet of bitcoin. We used bitcoin script to create a simple transaction, a multi-signature transaction and a password protected transaction.

In the second part of the assignment, we created a local ethereum network using geth and mined some blocks.

My research project was about coded merkle tree. I had to read this paper and provide a report and a presentation about it which is available in the Research Project directory.
