​A 3-day deep dive into xrpld, the software that runs the XRP Ledger, led by Denis Angell, CTO of the XRPL Foundation. This bootcamp is for developers who want to go beyond the application layer and work directly with our core codebase.

​Over three days, you'll move from ledger fundamentals to hands-on protocol engineering, covering state management and SHAMap architecture, the full transaction processing pipeline (transactors, fees, sequences), RPC architecture and how to build custom handlers, and storage backends and database operations. We'll close with amendments: how they're structured, and how they move through their lifecycle from proposal to activation.

​This bootcamp is hands-on throughout, with dedicated sessions building a State Ledger Entry and a custom RPC handler from scratch.

​This is a senior-level track intended either for C++ developers or for anyone eager to learn and contribute to the XRPL protocol.

​This is the perfect ramp-up to the XRP Ledger Hackathon Protocol Innovation track taking place the following weekend.

​Agenda

​Day 1 — State-management foundations · SHAMap architecture & hashing · Building a State Ledger Entry (hands-on)

​Day 2 — Transactor architecture · The transaction processing pipeline · State modification, fees & sequences · RPC architecture & request flow · Building a custom RPC handler

​Day 3 — Storage backends & database operations · Amendments overview & architecture · The amendment lifecycle

​Register now and stay tuned for prerequisites! Get your dev environment configured early so we can skip the onboarding and jump straight into building on day one.
