Ripple, formerly known as Ripple Labs, has officially streamlined its identity—signaling that its technology is no longer experimental but production-ready. This rebranding reflects a pivotal shift: Ripple’s solutions are now mature enough to be deployed at scale across financial institutions worldwide.
From its early days in 2012, Ripple stood out as one of the first well-funded innovators to explore practical applications of distributed ledger technology (DLT). Unlike Bitcoin, which relies on proof-of-work consensus, Ripple introduced its own consensus mechanism and native digital asset, XRP. Over time, the company has championed a vision known as the “Internet of Value”—a future where money flows as freely and instantly as data does today.
To make this vision a reality, Ripple has launched the Interledger Protocol (ILP), an open standard designed to bridge disparate ledgers, whether they’re blockchain-based or traditional centralized systems.

What Is the Interledger Protocol?
At its core, Interledger is not a ledger itself. It doesn’t maintain balances or achieve consensus. Instead, it functions as a cryptographic escrow layer that enables secure value transfer between different ledgers through intermediaries called connectors. These connectors act like financial routers, moving funds across systems without requiring trust.
One of ILP’s most powerful features is that it operates without a native token. This means each ledger retains its own unit of account—be it USD in a bank database, XRP on Ripple’s network, or points in a loyalty program. The protocol ensures interoperability without forcing adoption of a single currency or system.
As Stefan Thomas, Ripple’s CTO, explained:
“As long as your ledger supports Interledger, you can participate in a payment and someone will be able to provide liquidity. It can be PayPal, Alipay, bitcoin, bank ledgers or Skype—anywhere people hold balances, they have a ledger.”
This universal compatibility addresses a key limitation of current payment networks: the need for widespread adoption to be useful. With ILP, users don’t need everyone to switch to one system—they just need their own system to support the protocol.
Monica Long, Ripple’s VP of Marketing, emphasized that ILP is a true protocol:
“It creates ways for ledgers to interact. Bitcoin and Ripple are payment systems—they require everyone to adopt that system for users to interact.”
Two Modes for Different Trust Models
Interledger supports two primary modes of operation:
- Atomic Mode: Uses a group of trusted validators called notaries to confirm transactions. Ideal for enterprise environments where known entities manage risk.
- Universal Mode: Relies on economic incentives rather than trust. Untrusted institutions can serve as connectors because the protocol cryptographically guarantees fairness.
This dual approach makes ILP adaptable across various contexts—from tightly controlled banking networks to open, decentralized ecosystems.
For existing platforms like PayPal or traditional banks, integration is designed to be simple. According to Thomas:
“If you’re PayPal, all you would need to do is add a new payment to your API.”
Open-source reference implementations are set to be released soon, accelerating adoption and testing across real-world systems.
How Interledger Enhances Privacy and Liquidity
A major concern for financial institutions adopting public blockchains is data exposure. ILP solves this by enabling transfers between private versions of ledgers—keeping sensitive transaction data off public chains while still allowing cross-network settlement.
By using connectors, ILP allows banks to move funds securely without exposing internal operations. This maintains regulatory compliance and competitive advantage while unlocking new levels of efficiency.
Moreover, the protocol lowers barriers for potential liquidity providers. Connectors don’t need deep vetting since the escrow mechanism ensures funds are only released upon verified delivery. This opens the door for digital currency exchanges and fintech startups to become part of the global payments infrastructure.
Thomas noted:
“In order to lower the barrier, the first thing you have to do is ensure the connector doesn’t have to be trusted. They can provide liquidity without being that well-vetted.”
He compared ILP’s role to Blockstream’s sidechains, which extend Bitcoin’s functionality by linking alternative blockchains to the main chain. However, while sidechains focus on building new ledgers, ILP focuses on connecting them—regardless of type.
“Interledger is a complement to sidechains,” Thomas said. “Sidechains are about how you create these ledgers; ILP is about putting them together.”

Inspired by Web Standards: The W3C Connection
Although not formally affiliated with the World Wide Web Consortium (W3C), Ripple developed ILP with strong influence from its participation in the W3C’s Web Payments Interest Group. Founded by Tim Berners-Lee, W3C brings together industry leaders to build open standards for the internet—including digital payments.
Ripple has been involved since 2013, advocating for open, frictionless payment standards. Today, ILP is being refined within a dedicated W3C community group focused on interledger technologies.
Participants include representatives from:
- The National Association of Convenience Stores
- The Federal Reserve Bank of Minneapolis
- Eris Ltd
The goal? To position ILP as a foundational standard for web payments—just like HTTP or TCP/IP.
Thomas highlighted how scalability lessons from the web apply directly to finance:
“When you bring costs down, volumes increase dramatically. The key to scalability is not relying on one global system.”
This concept enables horizontal scalability—distributing transaction load across multiple ledgers instead of overloading a single network. Just as the internet scaled through decentralized routing, so too can global finance.
Real-World Applications and Market Validation
ILP isn’t just theoretical—it’s already shaping new products. Ripple recently unveiled two enterprise solutions powered by Interledger:
- Cross-Currency Settlement: Streamlines foreign exchange by reducing reliance on nostro/vostro accounts and correspondent banks.
- FX Market Making: Enables automated liquidity provisioning across currencies using XRP as a bridge asset.
These tools allow banks to offer faster, cheaper international transfers with better transparency for end customers.
Long explained:
“Today, a bank can send payment instructions—but there’s no way for the recipient to send information back. The sender can’t give accurate pricing or confirmation.”
With Ripple’s solutions, institutions gain real-time visibility into settlement status and exchange rates—especially valuable when privacy constraints are relaxed for compliance or audit purposes.
Currently, 30 banks are actively testing Ripple’s technology, with more announcements expected soon. While competitors like R3 focus on interbank settlements, Ripple differentiates itself by targeting cross-border payments—a market ripe for disruption.
Long sees this momentum as validation of Ripple’s long-term strategy:
“Blockchains are a part of that, but it’s about moving away from centralized systems.”
Frequently Asked Questions (FAQ)
Q: What problem does Interledger solve?
A: Interledger enables seamless money transfers between different financial systems—whether blockchains or traditional databases—without requiring trust or shared infrastructure.
Q: Does Interledger use XRP?
A: No, ILP itself doesn’t require any specific currency. However, Ripple promotes XRP as an efficient bridge asset within its ecosystem for cross-currency transactions.
Q: Can individuals use Interledger today?
A: Currently, ILP is focused on enterprise and institutional use. Consumer applications may emerge as adoption grows among banks and payment providers.
Q: How does Interledger ensure security?
A: Through cryptographic escrow mechanisms that guarantee funds are only released when conditions are met—eliminating counterparty risk even with untrusted connectors.
Q: Is Interledger open source?
A: Yes, reference implementations are open source and available for developers and institutions to integrate and test.
Q: How is ILP different from SWIFT?
A: Unlike SWIFT, which relies on pre-funded accounts and slow messaging protocols, ILP enables near-instant settlement across systems with minimal overhead and no need for intermediaries.
