Block Structures & Transactions sit at the very heart of how blockchains actually work. Every blockchain is built from blocks, and every block is built from transactions—small, precise records that move value, trigger smart contracts, and permanently update shared state. Understanding this layer reveals how decentralized systems stay organized, verifiable, and resistant to tampering. This category explores how transactions are formed, validated, grouped, and finalized inside blocks. You’ll learn how inputs and outputs define ownership, how fees influence transaction priority, and how block headers tie cryptography, timestamps, and consensus together. From mempools and gas limits to Merkle trees and block finality, these structures quietly coordinate millions of actions without a central authority. Whether you’re tracing a single transaction from wallet to confirmation or examining how blocks link into an immutable chain, Block Structures & Transactions helps you see blockchain not as magic—but as elegant engineering. Welcome to the layer where activity becomes history.
