Ethereum

A comprehensive guide to crypto tokens: what they are, real-life analogies, how they differ from cryptocurrencies, fungible vs. non-fungible tokens (NFTs), various token types (utility, security, governance), token creation with Solidity, ERC standards (ERC20, ERC721), ICOs, and interoperability challenges.

Explore the fundamental differences between UTXO-based (like Bitcoin) and Account-based (like Ethereum) blockchain models, how they track user balances, prevent double-spending or replay attacks, and their respective pros and cons.
