Blockchain Network Structure Explained: Full Nodes, Light Nodes, and the Role of Forks

Blockchain Network Structure Explained: Full Nodes, Light Nodes, and the Role of Forks

Explore the roles of full nodes (complete validation and storage) and light nodes (efficiency using block headers) in network structure. Learn how soft forks (backward-compatible) and hard forks (network fragmentation) introduce changes and resolve conflicts in a permissionless system.
