Ripple is a technology that acts as both a cryptocurrency and a digital payment network for financial transactions. The fee to conduct transactions on Ripple is also minimal, with the minimum transaction cost required for a standard transaction set at 0.00001 XRP, compared to the large fees charged by banks for conducting cross-border payments. Ripple transactions use less energy than bitcoin, are confirmed in seconds, and cost very little, whereas bitcoin transactions use more energy, take longer to confirm, and include higher transaction costs. Ripple's main process is a payment settlement asset exchange and remittance system, similar to the SWIFT system for international money and security transfers, which is used by banks and financial middlemen dealing across currencies. XRP is used in its products to facilitate quick conversion between different currencies To understand how the system works, consider a money transfer structure where the two parties on either end of the transaction use their preferred middlemen to receive the money.
What Is Ripple?
Ripple is a technology that acts as both a cryptocurrency and a digital payment network for financial transactions. It was first released in 2012; it was co-founded by Chris Larsen and Jed McCaleb. Ripple's main process is a payment settlement asset exchange and remittance system, similar to the SWIFT system for international money and security transfers, which is used by banks and financial middlemen dealing across currencies.
The token used for the cryptocurrency is premined and utilizes the ticker symbol XRP. Ripple is the name of the company and the network, and XRP is the cryptocurrency token. The purpose of XRP is to serve as an intermediate mechanism of exchange between two currencies or networks — as a sort of temporary settlement layer denomination.
Ripple operates on an open-source and peer-to-peer decentralized platform that allows for a seamless transfer of money in any form, whether it's dollars, Yen, euros, or cryptocurrencies, like litecoin or bitcoin. Ripple is a global payments network and counts major banks and financial services amongst its customers. XRP is used in its products to facilitate quick conversion between different currencies
Ripple as a Digital Hawala Network
To understand how the system works, consider a money transfer structure where the two parties on either end of the transaction use their preferred middlemen to receive the money. In effect, Ripple functions as a digital hawala service. Hawala is an informal method of transferring money, usually across borders, without any physical money actually moving.
Say that Lawrence needs to send $100 to David, who lives in a different city. Lawrence provides the funds to be sent to David to his local agent, Kate. Lawrence also provides the funds a secret password that David is required to answer correctly to receive the funds in his city. Kate alerts David’s agent, Rose, of the transaction details — recipient, funds to be reimbursed, and the password. If David gives Rose the right password, Rose gives him $100.
However, the money comes from Rose’s account, which means that Kate owes Rose $100 (which will be settled at a later date). Rose can either record a journal of all Kate’s debt, which Kate would pay on an agreed day, or make counter transactions that would balance the debt. For example, if Rose was also Martin’s agent and Martin needed to transfer $100 to Itios whose agent is Kate, this would balance out the $100 owed to Rose, since Itios will be paid from Kate’s account.
Although the Ripple network is a little more complex than this example, it demonstrates the basics of how the Ripple system works. From the example above, one can see that trust is required to initiate a transaction — trust between Lawrence and Kate, Kate and Rose, and David and Rose.
Ripple uses a medium, known as Gateway, as the link in the trust chain between two parties wanting to make a transaction. Gateway acts as the credit intermediary that receives and sends currencies to public addresses over the Ripple network. Anyone or any business can register and open a gateway, which authorizes the registrant to act as the middleman for exchanging currencies, maintaining liquidity, and transferring payments on the network.
Ripple's Digital Currency XRP
The digital currency, XRP, acts as a bridge currency to other currencies. It does not discriminate between any fiat/cryptocurrency, which makes it easy for any currency to be exchanged for another. Each currency on the ecosystem has its own gateway e.g. CADBluzelle, BTCbitstamp, and USDsnapswap. If David wanted bitcoins as payment for the services rendered to Lawrence, Lawrence does not necessarily have to be in possession of any bitcoins. He can send the payment to his gateway in Canadian dollars (CAD), and David can receive bitcoins from his gateway. One gateway is not needed to initiate a complete transaction; multiple gateways can be used, forming a chain of trust rippling across the users.
Holding balances with a gateway exposes the user to counterparty risk, a risk that is also present in the traditional banking system. If the gateway does not honor its liability, the user could lose the value of their money held at that gateway. Users that don’t trust a gateway can, therefore, transact with a trusted gateway that in turn deals with the "untrusted" gateway. This way the IOU will be transacted through the trusted, or creditworthy-certified, gateway. Counterparty risk does not apply to bitcoins (and most altcoins) since a user’s bitcoin is not another user’s IOU or liability.
How Ripple Works
The Ripple network does not run with a proof-of-work (PoW) system like bitcoin or a proof-of-stake (PoS) system like Nxt. Instead, transactions rely on a consensus protocol in order to validate account balances and transactions on the system. The consensus works to improve the integrity of the system by preventing double-spending.
A Ripple user that initiates a transaction with multiple gateways, but attempts to send the same $100 to the gateway systems, will have all but the first transaction deleted. Individual distributed nodes decide by consensus which transaction was made first. The confirmations are instant and take roughly five seconds. Since there’s no central authority that decides who can set up a node and confirm transactions, the Ripple platform is described as decentralized.
Ripple keeps track of all IOUs in a given currency for any user or gateway. IOU credits and transaction flows that occur between Ripple wallets are publicly available on the Ripple consensus ledger. But even though financial transaction history is publicly recorded and made available on a blockchain, the data is not linked to the ID or account of any individual or business. However, the public record of all dealings (i.e. the blockchain) makes the information susceptible to de-anonymization measures.
The Ripple payment system is mainly intended to be used by banks, although individual investors may speculate on the price of XRP.
Ripple improves on some of the drawbacks attributed to traditional banks. Transactions are settled within seconds on the Ripple network (even though the platform handles millions of transactions frequently). This is unlike banks which could take days or weeks to complete a wire transfer. The fee to conduct transactions on Ripple is also minimal, with the minimum transaction cost required for a standard transaction set at 0.00001 XRP, compared to the large fees charged by banks for conducting cross-border payments.
As of August 2021, one XRP is worth around $1.13, and Ripple was the sixth-largest cryptocurrency with a market cap of over $52 billion.
