The XRP Ledger

The XRP Ledger is a decentralized cryptographic ledger powered by a network of peer-to-peer nodes. The XRP Ledger uses a novel Byzantine Fault Tolerant consensus algorithm to settle and record transactions in a secure distributed database without a central operator.

XRP

XRP is a public, counterparty-free asset native to the XRP Ledger, and is designed to bridge the many different currencies in use worldwide. XRP is traded on the open-market and is available for anyone to access. The XRP Ledger was created in 2012 with a finite supply of 100 billion units of XRP.

rippled

The server software that powers the XRP Ledger is called rippled and is available in this repository under the permissive ISC open-source license. The rippled server software is written primarily in C++ and runs on a variety of platforms. The rippled server software can run in several modes depending on its configuration.

If you are interested in running an API Server (including a Full History Server) or a Reporting Mode server, take a look at Clio. rippled Reporting Mode is expected to be replaced by Clio.
