Learning Ethereum

This repository is a collection of examples and useful smart contracts that I am building while learning about Ethereum and Solidity. The purpose is to document my journey, share knowledge, and provide references for myself and others interested in Ethereum development.

Overview

This repository includes / will include:

• Basic Solidity examples demonstrating key concepts.
• Useful smart contracts for learning and experimenting.
• Comments and explanations for clarity and understanding.
• Explanation on various topics inluding
  • EVM
  • STACK
  • MEMORY
  • STORAGE

Contracts

1. DynamicArraysInStorage.sol

Demonstrates how Solidity organizes storage for state variables, particularly dynamic arrays. Key features include:

• Adding elements to a dynamic array.
• Reading raw storage slots.
• Computing keccak256 hashes of storage slots for array indexing.

2. DynamicArraysInMemory.sol

Explores the memory layout and gas costs associated with dynamic arrays in Solidity. Key features include:

• Probing memory slots for dynamic arrays.
• Demonstrating memory expansion and its quadratic gas cost.
• An example function that intentionally causes a gas exhaustion error.
