Building on your existing knowledge, this section takes you deep into the internal workings of Rippled, the core server software of the XRP Ledger.

‍

You’ll gain a complete understanding of how the protocol operates from transaction processing and consensus to peer-to-peer communication and how these components work together to maintain a fast, secure, and decentralized network.

You’ll explore the modular design of Rippled, examining how each layer contributes to the network’s functionality.

‍

The Application layer orchestrates all major components, while the Transactor framework handles different transaction types.

‍

The consensus engine coordinates with validators to agree on the ledger state, and the overlay network ensures efficient peer-to-peer communication and transaction propagation across the decentralized ecosystem.

‍

Hands-on exercises will guide you through the complete path of a payment transaction — from submission to validation, consensus, and final inclusion in a closed ledger.

‍

You’ll also learn how to use debugging tools, interpret log output, and navigate the Rippled codebase effectively.

‍

This practical understanding forms the foundation for anyone aiming to contribute to the protocol, implement custom amendments, or build advanced applications on top of the XRP Ledger.
