Ripple is laying the groundwork for a post-quantum future with a comprehensive roadmap to upgrade the XRP Ledger (XRPL) against emerging cryptographic threats. The initiative comes as advances in quantum computing raise concerns about the long-term security of blockchain systems.

Recent developments from Google Quantum AI have intensified discussions around how quantum machines could eventually break widely used cryptographic standards. While such risks are not immediate, Ripple argues that preparation must begin now—especially for systems designed to store long-term value.

Why Quantum Risk Matters for Blockchain

Modern blockchains rely on cryptographic algorithms to secure wallets, validate transactions and protect user funds. However, sufficiently advanced quantum computers could theoretically break these systems, exposing private keys and compromising assets.

A growing concern is the so-called “harvest now, decrypt later” strategy, where attackers collect encrypted blockchain data today with the intention of decrypting it once quantum capabilities mature. This creates a delayed but serious risk for long-lived assets.

For XRPL, the issue is particularly relevant because public keys are revealed during transactions. Over time, this exposure could make accounts vulnerable in a post-quantum environment if no migration path exists.

XRPL’s Built-In Advantages

Ripple emphasizes that XRPL is not starting from scratch. The network already includes features that make future upgrades more feasible compared to other blockchains like Ethereum.

One key advantage is native key rotation, which allows users to update their cryptographic keys without changing account addresses. This enables gradual migration away from potentially vulnerable keys. Additionally, XRPL supports seed-based key generation, allowing deterministic creation of new keys.

While these features are not quantum-resistant on their own, they provide a strong foundation for transitioning to new cryptographic standards without disrupting users.

A Four-Phase Roadmap to 2028

Ripple’s strategy is structured as a multi-phase roadmap aimed at achieving full post-quantum readiness by 2028.

The first phase focuses on “Q-Day” preparedness, a contingency plan for a scenario where current cryptography is suddenly broken. This includes mechanisms to securely migrate funds to quantum-resistant accounts, potentially using advanced techniques like zero-knowledge proofs.

The second phase, underway in 2026, involves testing quantum-resistant algorithms recommended by global standards bodies such as the National Institute of Standards and Technology. This includes evaluating their impact on performance, storage, and network efficiency.

In the third phase, Ripple plans to introduce hybrid systems where traditional and quantum-resistant cryptography run in parallel. This allows developers to test new systems without disrupting the existing network.

The final phase targets full implementation, with XRPL transitioning to native post-quantum cryptography across the ecosystem by 2028.

Collaboration and Industry Efforts

Ripple is working with partners like Project Eleven to accelerate development. This includes validator-level testing, custody solutions, and real-world simulations of quantum-resistant systems.

The company is also exploring broader cryptographic innovations, including quantum-safe zero-knowledge proofs and encryption methods that could enhance privacy and compliance features on XRPL.

Preparing for a Quantum Future

Ripple’s roadmap highlights a growing recognition across the crypto industry: quantum computing is no longer a distant possibility but a credible future risk.

By starting early, Ripple aims to ensure that XRPL remains secure, scalable, and reliable even as the underlying technological landscape evolves. The approach balances innovation with caution, focusing on gradual migration rather than disruptive overhauls.

If successful, the initiative could position XRPL as one of the first major blockchain networks ready for the quantum era—well before the threat becomes urgent.

Coinbase is expanding its push into artificial intelligence with the launch of Agentic.market, a new marketplace built on its x402 payments protocol that allows AI agents to discover and use digital services autonomously.

The platform aims to solve a growing problem in the AI ecosystem: fragmentation. While AI agents are increasingly capable of executing tasks and even making payments, finding compatible services has largely relied on manual discovery and informal networks.

Building an App Store for AI Agents

Agentic.market is designed as a centralized hub where both humans and AI agents can browse, compare and access services that integrate with the x402 protocol. According to Coinbase product lead Nick Prince, the goal is to provide access to thousands of services without requiring traditional API keys.

The marketplace includes integrations with platforms such as CoinGecko, Google Flights and X, enabling AI agents to perform a wide range of tasks, from retrieving data to booking travel or interacting with online communities.

Beyond a user-facing interface, the platform also includes a programmable layer that allows AI agents to autonomously search for services, integrate new capabilities and execute tasks in real time without human intervention.

How the x402 Protocol Powers Payments

At the core of the system is the x402 protocol, launched by Coinbase in 2025. Named after the rarely used HTTP “402 Payment Required” status code, the protocol enables AI agents to make internet-native payments using stablecoins such as USD Coin.

Each AI agent on the platform is equipped with a wallet and a set of “skills,” which define how it interacts with different services. This allows agents not only to pay for services but also to offer services themselves, creating a two-sided marketplace powered by blockchain payments.

Coinbase says that hundreds of thousands of AI agents have already processed hundreds of millions of dollars in transaction volume using x402, highlighting early traction for the model.

Growing Industry Support for AI Payments

The launch comes amid increasing industry interest in combining AI with blockchain-based payments. Earlier this month, major technology firms including Google, Microsoft, and Amazon Web Services backed the formation of the x402 Foundation, which will oversee the protocol’s development.

Additional support has come from payments giants such as Visa and Mastercard, as well as crypto and fintech firms including Circle, Polygon Labs, and Solana Foundation.

This broad backing reflects a shared view that AI agents could soon become major economic actors, requiring efficient and programmable payment systems.

A Glimpse into the Future of Digital Commerce

Coinbase CEO Brian Armstrong has repeatedly emphasized that AI agents may soon outnumber humans in online transactions. Industry leaders like Jeremy Allaire have echoed this outlook, predicting billions of AI agents will transact on blockchain networks within a few years.

By launching Agentic.market, Coinbase is positioning itself at the intersection of these trends. If AI agents do become dominant participants in digital commerce, platforms like this could form the backbone of a new, machine-driven economy where software not only executes tasks, but also earns, spends and interacts independently.

Japan is taking another step toward integrating blockchain into traditional finance, as Japan Securities Clearing Corporation (JSCC) launches a new pilot to test the use of government bonds as digital collateral.

The initiative, conducted in partnership with Mizuho Financial Group, Nomura Holdings and Digital Asset, will explore how Japanese Government Bonds (JGBs) can be tokenized and utilized within blockchain-based financial infrastructure.

Testing Digital Collateral on the Canton Network

At the center of the project is the Canton Network, a privacy-enabled blockchain designed for institutional finance. The proof of concept will examine whether JGBs can be transferred, managed, and reused as collateral onchain while maintaining compliance with Japan’s legal framework.

A key focus of the trial is ensuring that digitized bonds retain their legal status under existing regulations, including the Book-Entry Transfer Act and the Financial Instruments and Exchange Act. This is critical for enabling blockchain-based systems to operate alongside established financial infrastructure.

The pilot will also test whether integrating legacy systems with blockchain technology can support real-time, 24/7 collateral management, something that traditional systems struggle to achieve due to operational constraints and settlement delays.

Bridging Traditional Finance and Blockchain

Japan’s move reflects a broader global trend toward modernizing financial markets through distributed ledger technology. Government bonds are among the most widely used forms of collateral in global finance, underpinning everything from derivatives trading to liquidity management.

By bringing JGBs onto blockchain rails, the project aims to unlock greater efficiency in how collateral is allocated and reused across institutions. This could reduce friction, lower costs, and improve capital efficiency for market participants.

The initiative has also received backing from Japan’s Financial Services Agency as part of its Payment Innovation Project, signaling regulatory support for experimentation in digital finance.

Building on Global Tokenization Efforts

The Canton Network has already been used in similar experiments involving tokenized government securities. In late 2025, a pilot demonstrated how tokenized US Treasuries could be reused as collateral in real time among major financial institutions.

That earlier trial included global players such as Bank of America and Société Générale, highlighting the growing interest in blockchain-based collateral systems across major markets.

Japan’s latest initiative extends this concept to one of the world’s largest sovereign debt markets. The outcome could influence how digital collateral frameworks are designed not only domestically but also in cross-border contexts.

Implications for the Future of Financial Markets

While the project remains in the experimental phase, it represents a significant step in the evolution of capital markets infrastructure. If successful, tokenized government bonds could enable faster settlement cycles, improved transparency, and more flexible use of collateral across global markets.

At this stage, no timeline has been set for commercial deployment. However, the findings from the pilot are expected to inform future discussions on integrating blockchain into Japan’s financial system.
