#The World’s Fastest and Most Secure Payment System
|
||
|
||
**What is Ripple?**
|
||
|
||
Ripple is the open-source, distributed payment protocol that enables instant
|
||
payments with low fees, no chargebacks, and currency flexibility (for example
|
||
dollars, yen, euros, bitcoins, or even loyalty points). Businesses of any size
|
||
can easily build payment solutions such as banking or remittance apps, and
|
||
accelerate the movement of money. Ripple enables the world to move value the
|
||
way it moves information on the Internet.
|
||
|
||
|
||
|
||
**What is a Gateway?**
|
||
|
||
Ripple works with gateways: independent businesses which hold customer
|
||
deposits in various currencies such as U.S. dollars (USD) or Euros (EUR),
|
||
in exchange for providing cryptographically-signed issuances that users can
|
||
send and trade with one another in seconds on the Ripple network. Within the
|
||
protocol, exchanges between multiple currencies can occur atomically without
|
||
any central authority to monitor them. Later, customers can withdraw their
|
||
Ripple balances from the gateways that created those issuances.
|
||
|
||
**How do Ripple payments work?**
|
||
|
||
A sender specifies the amount and currency the recipient should receive and
|
||
Ripple automatically converts the sender’s available currencies using the
|
||
distributed order books integrated into the Ripple protocol. Independent third
|
||
parties acting as market makers provide liquidity in these order books.
|
||
|
||
Ripple uses a pathfinding algorithm that considers currency pairs when
|
||
converting from the source to the destination currency. This algorithm searches
|
||
for a series of currency swaps that gives the user the lowest cost. Since
|
||
anyone can participate as a market maker, market forces drive fees to the
|
||
lowest practical level.
|
||
|
||
**What can you do with Ripple?**
|
||
|
||
The protocol is entirely open-source and the network’s shared ledger is public
|
||
information, so no central authority prevents anyone from participating. Anyone
|
||
can become a market maker, create a wallet or a gateway, or monitor network
|
||
behavior. Competition drives down spreads and fees, making the network useful
|
||
to everyone.
|
||
|
||
|
||
###Key Protocol Features
|
||
1. XRP is Ripple’s native [cryptocurrency]
|
||
(http://en.wikipedia.org/wiki/Cryptocurrency) with a fixed supply that
|
||
decreases slowly over time, with no mining. XRP acts as a bridge currency, and
|
||
pays for transaction fees that protect the network against spam.
|
||
|
||
|
||
2. Pathfinding discovers cheap and efficient payment paths through multiple
|
||
[order books](https://www.ripplecharts.com) allowing anyone to [trade](https://www.rippletrade.com) anything. When two accounts aren’t linked by relationships of trust, the Ripple pathfinding engine considers intermediate links and order books to produce a set of possible paths the transaction can take. When the payment is processed, the liquidity along these paths is iteratively consumed in best-first order.
|
||
|
||
|
||
3. [Consensus](https://www.youtube.com/watch?v=pj1QVb1vlC0) confirms
|
||
transactions in an atomic fashion, without mining, ensuring efficient use of
|
||
resources.
