ESP32 Blockchain Communication with Microservices

This repository contains an advanced project focused on using ESP32 microcontrollers and implementing blockchain technology to enable secure communication between microservices. The project integrates embedded system programming, blockchain encryption, and C++ tutorials, making it a comprehensive resource for developers interested in IoT, blockchain, and C++ programming.

Project Overview

This project aims to:

1. ESP32 Microcontroller Integration: Use ESP32 microcontrollers for communication between IoT devices, establishing a decentralized network.
2. Blockchain Implementation: Implement blockchain to ensure secure communication between microservices and devices, using encryption for authenticity and integrity.
3. C++ Practice and Training: Provide C++ examples and practice tasks, covering essential programming concepts useful for embedded systems development.

Content

The project is organized into the following sections:

1. Blockchain Communication Setup:

   • Public and Private Key Encryption: Using RSA for public and private key encryption to secure data transmission (outn.cpp, private_key.pem, public_key.pem).
   • Signature Verification: Demonstrating how to sign and verify messages in the blockchain setup (sig.cpp, sig2.cpp).

2. ESP32 Microcontroller Modules:

   • Basic Setup and Configuration: Setup files for the ESP32 microcontroller and g++ compiler configuration (T1, T1.cpp).
   • Microservices Communication: Implementing decentralized communication across multiple ESP32 nodes, allowing them to exchange data securely.

3. C++ Tutorials and Practice:

   • Basic C++ Concepts: Introduction to essential C++ topics, with practice files such as helloworld.cpp and other basic examples (hw.cpp).
   • Advanced C++ Techniques: Covering advanced C++ programming tasks, including function forwarding and lambda expressions (T3_FX.cpp, T4_FX2.cpp, T5_forwardFX.cpp).
