What Is the XRP Ledger?
The XRP Ledger (XRPL) is an open-source, decentralized blockchain that has been running continuously since 2012. It is one of the most mature and reliable blockchains in existence, with zero downtime in over a decade of operation.
How XRPL Works
Unlike Bitcoin (which uses Proof-of-Work mining), the XRP Ledger uses a consensus protocol called the Federated Byzantine Agreement (FBA). A network of validators — operated by universities, businesses, and individuals worldwide — agree on the state of the ledger every 3–5 seconds.
No single entity controls the XRPL. Validators run independently and must reach consensus to advance the ledger.

Transaction Finality on XRPL
One of XRPL's most important features is immediate transaction finality. Once a transaction is validated (3–5 seconds), it is mathematically final. There is no risk of a 'chain reorganization' that could reverse a confirmed transaction, as can happen on Bitcoin or Ethereum with long confirmation waiting periods.
