In this article, we are going to build a simple Ethereum wallet from scratch using Python. In part 1, we will use some cryptography and try to interact with the blockchain. We will generate a key pair compatible with the public key and encrypt the private key using a password. The cryptographic standard used by Bitcoin is based on Elliplic Curve Cryptography. An Ethereum wallet is simply a specific set of cryptographic keys together with methods to send and receive tokens using these keys. The wallet should at least be able to generate and store public and private keys. We start by loading some of them into Python:
