-# Mina zkApp: O1js Ecdh Secp256k1
+# ECDH secp256k1 - o1js
+
+## Overview
+This project provides an implementation of the Elliptic Curve Diffie-Hellman (ECDH) key exchange protocol using the secp256k1 curve, built on top of the o1js library. ECDH allows two parties to securely exchange cryptographic keys over a public channel.
+
+## What is ECDH?
+Elliptic Curve Diffie-Hellman (ECDH) is a key exchange mechanism based on elliptic curve cryptography (ECC). It allows two parties, each with a public and private key pair, to establish a shared secret over an insecure channel. This shared secret can then be used to securely encrypt further communication.
+
+The secp256k1 curve is a widely-used elliptic curve, particularly in blockchain and cryptocurrency applications such as Bitcoin & Ethereum.
+
+There are interesting use cases such as:
