need of centralized clearing house• Ripple’s distributed financial technology allows banks to directly transact
with other banks to settle transactions in real time• Ripple provides an alternative to today’s global payment infrastructure
WHAT IS RIPPLE?

CROSS BORDER PAYMENTS - TODAY
• Involves delays; generally takes around 2-4 days• Counterparty risks• Involves costs and fees; settlement costs are high• lengthy settlement times, and a poor customer experience• Less transparent
CROSS BORDER PAYMENTS FLOW - TODAY• Most banks relay transactions through a network of correspondents • More Cost• Cross-border payments have to be routed through a series of counterparties

RIPPLE – KEY COMPONENTS
Key components of Ripple
source : https://ripple.com/solutions/executive-summary-for-financial-institutions/
RIPPLE NETWORK
• A distributed system which does not require central operator• The Ripple network contains the Ripple Consensus Ledger (RCL)• RCL is a secure distributed ledger which uses Consensus process to
settle transactions• RCL holds the order book with bid/ask offers from payment initiators and
liquidity providers• Ripple Connect connects to the Ripple Consensus Ledger over WSS to
settle payments in near real-time on the RCL
RIPPLE STREAM
• An order book management system• Enables FX trading desks to facilitate FX markets on the RCL• RCL holds the order book with bid/ask offers from payment
initiators and liquidity providers• Enables cross currency payments using foreign exchange
RIPPLE CONNECT
• Component that processes international payments for banks• Communicates with the Ripple network to get the lowest currency
quotes• Provides secured Rest apis for communication• Connects to the receiving bank’s Ripple Connect to exchange KYC and
risk information, fees, payment details and expected time of funds delivery• Provides information about total costs of the transaction to sending bank
RIPPLE CONNECT INTEGRATION
• Payment processing involves 6 workflows• Rest Connect has exposed Restful services• The services are secure, reliable and highly available• Integration involves work flow development; all workflows are
serially executed• Except first two work flow are workflows are based on event pull
model
RIPPLE CONNECT INTEGRATION
• GetQuote Initial sender requests for a quote from sending institution Sender provides sender details, final receiver details, amount and currency to be received Ripple connect instance at sending institution provides sender FX rate for the payment; response also includes fees
o It involves communication with Ripple connect at receiving end o Querying Ripple networko Path finding algorithm
Payment object is in “quoted” state
• AcceptQuote Initial Sender gets the quote (previous step) Reviews quote and approves/rejects the quote Payment object is in “accepted” state
RIPPLE CONNECT INTEGRATION
• LockQuote (Receiver) Receiving institution polls its Ripple Connect instance for payments in an "accepted" state Receiving institute retrieves any additional information (such as PII) requested by the sending
institution Submits Lock Request Payment status is “locked”
• Submit Payment (Sender) Sender polls for payments which are in “locked” status Sender performs essential activities such as posting, compliance Sender executes submit payment request Payment status is in “In_Progress”
RIPPLE CONNECT INTEGRATION
• Submit Payment (Receiver) Receiver polls for payments which are in “In_Progress” status Receiver performs essential activities such as posting Sender executes submit payment request Payment status is in “Succeeded” Payment is complete from receiver side Payment is complete on ripple network
• Complete Payment (Sender) Sender polls for payments which are in “Succeeded” status Sender marks payment as complete End to end payment is complete
COMPLIANCE
The regulatory treatment of Ripple is dependent on several factors, such as: • The type client being serviced• Country and geographic region of operations • Volume and scope of activity• Other factors determined by financial institution or regulator
• Ripple has engaged with central banks and regulators globally to educate them on distributed networks• Ripple works with each financial institution to identify and meet all relevant regulatory requirements

SECURITY
In financial world, especially in payment security is at most important
Ripple provides highest level of security to ensure that payments data is secured in every manner
Ripple employs different methodologies at different levels to ensure highest level of security
SECURITY
• Cryptographic Security Financial transactions on Ripple are signed using industry-standard
cryptographic algorithms ECDSA and ED25519 Ripple servers use public/private key cryptography to validate
transactions Each submitted transaction is signed with a unique digital signature Ripple apis are accessed using secured access token based
mechanism

SECURITY
• Payment Data Separation Ripple provides a layer of separation and security between payment data and settlement Actual payment data is encrypted and shared only between the two institutions making
payments to each other
• Payment Data Separation Communication is over secure HTTPS using OAuth 2.0 Ripple Connect connects to the Ripple Consensus Ledger over WSS (Secure websockets) Ripple network leverages TLS to ensure communication is secure between all the nodes
on the network
