Does XRP have a whitepaper?

XRP does not have a Bitcoin-style monetary manifesto in the same simple sense. The better source cluster is the Ripple consensus whitepaper and current XRP Ledger consensus documentation.

XRP Ledger consensus

XRP Ledger consensus is the process used to agree on transaction ordering and ledger state without proof-of-work mining.

Validators

Validators share proposals and validations. Their role is to help the network converge on the next ledger state.

Unique Node List

A Unique Node List, or UNL, is the set of validators a server listens to for consensus decisions.

Ledger close

Ledger close is the process of moving from candidate transactions to an agreed ledger version.

XRP vs Ripple vs XRP Ledger

XRP is the asset, XRP Ledger is the public blockchain network, and Ripple is a company associated with parts of the ecosystem and historical development.

How to read the sources

Read the 2014 Ripple consensus whitepaper as historical context, then compare it with current XRPL documentation and correction material.
