The origins of XRP and Ripple trace back to Ripplepay, a peer-to-peer payment network created in 2004 by Ryan Fugger. Fugger aimed to build a payments service that would create a network of interconnected individuals and strangers who could extend credit and exchange debt through the people they knew in the network. McCaleb and Larsen were developing their own digital currency project around the same time and contacted Fugger, who subsequently entrusted the project to them.
Created in 2014, XRP is the native asset of the XRP ledger, developed by San Francisco startup Ripple. Ripple aims to use blockchain technology and XRP to improve cross-border payments.
Ripple’s products include xCurrent (a software that banks can use for cross-border payments), xRapid (for financial institutions to manage liquidity costs) and xVia (a user interface to make xCurrent and xRapid easier to use). XRP is used on xRapid to provide liquidity in cross-border payments that involve illiquid trading pairs.
Ripple created 100 billion XRP tokens at the project’s inception, and, as of 2018, the company held approximately 60 percent of these tokens.
In 2015, the Financial Crimes Enforcement Network (FinCen) fined Ripple and its subsidiary, XRP II, $700,000 for failing to register as a money services business (MSB) before selling XRP, in addition to failing to implement appropriate anti-money laundering procedures. Ripple eventually agreed to pay a $450,000 fine and to settle potential criminal charges resulting from the investigation.
In 2018, several lawsuits were filed against Ripple that alleged that XRP should have been classified as a security because the company used the sale of the tokens to fund the Ripple ecosystem. These lawsuits were filed due to investors losing money after XRP’s price drop.

Launch & issuance
1 billion XRP tokens were created at the launch of the project in 2012. In 2017, Ripple placed 55 percent of XRP’s total supply (55 billion XRP) into an escrow account, which would be able to sell 1 billion tokens a month for 55 months to investors.
At the end of each selling period, Ripple will return the unsold tokens to the escrow for distribution beyond the 55 months. The company has not historically sold 1 billion XRP per month, but approximately 300 million per month, according to data gathered from 2016 to 2018.
Network Design & Security Model
Ripple developed their own blockchain technology, the XRP ledger, to facilitate cross-border payments between various banking systems in the world. The ledger is a decentralized network of peer-to-peer servers that helps power all relevant operations. The native token to this ledger, XRP, is intended to act as a bridge between currencies around the world.
The XRP ledger uses the Ripple Consensus Algorithm, which differs from bitcoin’s proof-of-work and ethereum’s proof-of-stake mechanisms. This algorithm enables participants – trusted nodes – to have an overlapping set of trusted validators that all have to agree on which transactions happen in what order.
Once all validators agree, a new block (called “ledger version”) is created. Once validated, the block’s content cannot be changed. This allows for all servers in the network to store a complete history of the ledger state.
Monetary Policy & Crypto-Economics
The total supply of XRP is 100 billion tokens, all of which were created in 2012. The available supply will decrease over time as the network destroys the tokens to pay for transaction costs.
At time of issuance, founders Chris Larsen, Jed McCaleb and Arthur Britto retained 20 billion XRP for themselves as compensation for starting the company.
In 2017, Ripple placed 55 percent of XRP’s total supply (55 billion XRP) into an escrow account, with the account selling 1 billion tokens a month for 55 month to users. At the end of each sale period, ripple will return the unsold tokens to the escrow for distribution beyond the 55 months.
According to Ripple’s XRP documentation, the ledger settles payments in under 5 seconds and can handle over 1,500 transactions per second. The minimum transaction fee is 0.00001 XRP, and tokens are destroyed as an anti-spam feature.
Additionally, transactions that destroy more XRP can move to the front of the transaction queue when there is a high volume of transactions being processed. All transactions are done on ledger.
