Ripple 2028 Plan: Ripple Makes XRP Ledger Quantum-Ready

Early Threats Recovery Plan

The first phase focuses on recovery actions in case of the failure of classical cryptography. Engineers will introduce a comprehensive migration trajectory, which will require users to transfer funds to quantum-secure accounts. Moreover, the strategy will guarantee that user assets are not exposed in case of a transition event caused by compromised keys. Ripple engineers are exploring zero-knowledge proof systems that prove ownership of existing accounts without disclosing any private keys. As a result, the network will be able to promote safe migrations and safeguard sensitive information. The XRP Ledger already has building blocks that facilitate this approach such as seed-based key generation.

The second step is concerned with testing the algorithms suggested by the National Institute of Standards and Technology. In addition to in-house testing, Ripple has collaborated with Project Eleven to build hybrid signing systems that fuse existing and post-quantum techniques. The next stage will involve developers starting to incorporate new signature systems with the existing elliptic curve techniques. Additionally, developer networks will begin to be tested to enable applications to be modified. Ripple will also analyse encryption tools that uphold privacy and compliance to tokenized assets.

The final stage involves a full transition toward post-quantum cryptography within the XRP Ledger ecosystem. Ripple therefore intends to implement protocol changes that will facilitate the adoption of new signature systems on a large scale. This move will transition the network from testing into full deployment in line with the stated timeline. The XRP Ledger already includes features to enable long-term resilience against quantum risks. Notably, key rotation enables users to refresh private keys without changing accounts, and deterministic generation of keys enables security upgrades to be controlled. These functionalities will provide a foundation for future upgrades as quantum technology advances.

Coinbase's x402 launches AI agents app store for payments

Coinbase-backed x402 has unveiled Agentic.market, a dedicated marketplace aimed at increasing the usefulness of AI agents by aggregating thousands of apps and services that agents can access without any API keys. The rollout positions the platform as a central hub for agents to discover, evaluate, and deploy capabilities across a standardized payments layer. Coinbase product lead Nick Prince described Agentic.market in a video posted on X as a storefront for discovering, comparing, and using x402 services. The marketplace is designed to give both humans and their AI agents access to a wide range of tools—from data feeds to consumer apps—without the friction of managing API credentials. A storefront for discovering, comparing, and using x402 services. Thousands of services. Zero API keys. Powered by x402. Prince added that the market offers a web interface for humans to browse and assess services, alongside a programming layer that lets AI agents autonomously search, filter, and integra...

Top Cryptocurrencies to Watch: BTC, ETH, BNB, XRP, Solana, Dogecoin & More

Market Analysis and Price Predictions for Key Cryptocurrencies Recent market dynamics reveal a cautious sentiment across the cryptocurrency landscape, with Bitcoin struggling to maintain levels above $90,000 and many major altcoins facing downward pressure. Indicators point toward reduced participation from both institutional and retail investors, raising concerns about a potential consolidation phase after notable gains earlier in the year. Bitcoin has fallen below $87,000, reflecting waning demand at higher price points. Institutional fund flows into BTC and ETH ETFs have turned negative, indicating a period of subdued market activity. Active addresses and Binance deposit/withdrawal activities are at annual lows, suggesting market indecision. Most leading altcoins are approaching support levels, with some poised for potential breakdowns. Tickers mentioned: Bitcoin, Ethereum, Binance Coin, XRP, Solana, Dogecoin, Cardano, Bitcoin Cash, Chainlink, Hyperliquid Sentiment: Neutral to Sli...

Analyst: Bitcoin can reclaim $100K without a new narrative

Bitcoin has stalled below the $100,000 threshold, marking a run of almost five months without a breakout above that level. As of the latest market close, BTC hovered around $78,250 after a February nadir of about $60,000, underscoring a slow, grinding recovery amid broader market dynamics. In parallel, tech markets—especially AI-focused equities—have captured the spotlight, with investors rotating capital away from crypto in search of different risk-reward profiles. Nvidia (NVDA), the leading AI stock by market cap, has gained about 5.08% since the start of the year, while Bitcoin has faced a roughly 10% dip over the same period, illustrating a diverging performance within risk assets. MN Trading Capital founder Michael van de Poppe suggested that Bitcoin may not require a fresh narrative to push back above $100,000. In a post on X, he asked what narrative would drive BTC to the milestone and concluded that “price moves upwards, and the narrative will create itself.” He continued that ...
