The XRP Ledger

The XRP Ledger is a decentralized cryptographic ledger powered by a network of peer-to-peer servers. 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. Its creators gifted 80 billion XRP to a company, now called Ripple, to develop the XRP Ledger and its ecosystem. Ripple uses XRP to help build the Internet of Value, ushering in a world in which money moves as fast and efficiently as information does today.

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 is written primarily in C++ and runs on a variety of platforms.

Key Features of the XRP Ledger

  • Finite XRP Supply: When the XRP Ledger began, 100 billion XRP were created, and no more XRP will ever be created. The available supply of XRP decreases slowly over time as small amounts are destroyed to pay transaction costs.
  • Interledger Protocol. This toolbox of advanced features comes with safety features like a process for amending the network and separate checks against invariant constraints.
  • On-Ledger Decentralized Exchange: In addition to all the features that make XRP useful on its own, the XRP Ledger also has a fully-functional accounting system for tracking and trading obligations denominated in any way users want, and an exchange built into the protocol. The XRP Ledger can settle long, cross-currency payment paths and exchanges of multiple currencies in atomic transactions, bridging gaps of trust with XRP.
