Blocks = Pages
Each block contains a list of transactions. Once full, it is sealed and added to the chain.
Chain = Binding
Each block is cryptographically linked to the previous one, creating an unbreakable sequence.
Distributed
Everyone has a copy. No single master copy to attack. Updates sync across the entire network.
Gas Fees
Crypto pays validators for processing transactions. Economic incentives keep the network honest.
This module explains the core technology behind Web3. We'll break down what a blockchain is, how it works, and the important role cryptocurrencies play in making these decentralized networks function.
