Why is Ripple focusing on quantum security for the XRP Ledger?

Ripple partnered with Project Eleven because future quantum computers could eventually break the cryptographic systems protecting blockchains today. Ripple said it wants the XRP Ledger to be prepared before quantum threats become practical.

What is the main quantum computing risk for blockchains?

Quantum computers could potentially break current public-key cryptography systems used to secure wallets, signatures and blockchain transactions. If that happens, attackers may theoretically gain the ability to forge transactions or compromise wallet security.

Which cryptocurrencies could be vulnerable to quantum attacks?

Project Eleven said major blockchain networks including Bitcoin, Ethereum, Solana and XRP all rely on cryptographic systems that could eventually face quantum-related vulnerabilities.

What will Ripple and Project Eleven actually build together?

The partnership includes security audits of the XRP Ledger’s validator, custody, networking and wallet systems. The companies also plan to develop hybrid quantum-resistant signature systems and a prototype quantum-secure custodial wallet.

What are hybrid quantum-resistant signatures?

Hybrid signature systems combine existing cryptography with newer quantum-resistant algorithms. This approach allows blockchains to gradually transition toward post-quantum security without immediately replacing current infrastructure.

Why is Ripple treating quantum computing as an urgent issue now?

J. Ayo Akinyele said the threat is no longer purely theoretical because governments and technology firms are already preparing post-quantum security standards. Ripple wants production-ready solutions before large-scale quantum computers become viable.

What advantages does the XRP Ledger already have for future upgrades?

Ripple said the XRP Ledger already supports features such as validator coordination and key rotation, which could make security upgrades easier to implement. These infrastructure features may help accelerate a transition toward post-quantum cryptography.

Why are governments preparing for post-quantum security now?

The US government plans to phase out vulnerable encryption standards in federal systems by 2035. Technology companies including Google and Cloudflare are also preparing transitions toward quantum-resistant security standards later this decade.

Ripple expands quantum security push for XRP Ledger

Ripple has partnered with Project Eleven to strengthen the security of the XRP Ledger against future quantum computing threats.

Project Eleven said the collaboration will focus on auditing the XRP Ledger’s validator, custody, wallet and networking systems while developing quantum-resistant infrastructure and hybrid cryptographic signature systems.

The company warned that sufficiently powerful quantum computers could eventually break the cryptographic systems currently protecting major blockchain networks including Bitcoin, Ethereum, Solana and XRP.

“Every major blockchain is exposed to the same cryptographic vulnerability,”

Said Alex Pruden.

Project Eleven said the partnership aims to produce working code, performance testing and production-ready security tools, including a quantum-secure custodial wallet prototype for institutional infrastructure.

J. Ayo Akinyele said the quantum threat was no longer purely theoretical and argued the XRP Ledger already benefits from infrastructure features such as key rotation and validator coordination that could help accelerate future upgrades.

The move comes as governments and technology companies accelerate post-quantum security planning, with the US government aiming to phase out vulnerable encryption standards across federal systems by 2035 while firms including Google and Cloudflare target transitions toward post-quantum cryptography later this decade.

Project Eleven, founded in 2024, previously raised $20 million in funding led by Castle Island Ventures and is also developing quantum-risk monitoring tools and secure wallet infrastructure for digital assets.

At the time of reporting, XRP price was $1.35.
