The <a href="https://zycrypto.com/tag/xrp-ledger/" rel="noopener noreferrer nofollow">XRP Ledger</a> is preparing for a major security overhaul as quantum computing moves from a theoretical concern to a growing priority for the crypto industry. With <a href="https://zycrypto.com/tag/ripple/" rel="noopener noreferrer nofollow">Ripple</a> targeting 2028 for its post-quantum security transition, developers are now unveiling a proposed quantum-resistant upgrade that promises to protect users against future attacks without introducing additional transaction fees.
The development could mark a significant turning point for the network, raising questions about what exactly is changing, how the upgrade will work, and whether XRP holders will need to do anything before the looming security deadline.

The XRP community has a new development to watch as the XRP Ledger Foundation <a href="https://x.com/WhaleInsider/status/2120053674072285451" rel="noopener noreferrer nofollow">outlines</a> plans to strengthen the network against future quantum computing risks. The proposed upgrade would introduce quantum-resistant accounts, giving users an additional layer of protection against emerging cryptographic threats while keeping transaction costs unchanged.
Although the feature has yet to be implemented, the proposed upgrade would allow XRP Ledger users to register NIST-approved ML-DSA-44 quantum-resistant signing keys and deactivate their existing authentication keys. This would give accounts an additional layer of protection against potential quantum computing attacks, particularly those whose public keys have already been exposed on the network.
Importantly, users could adopt the enhanced security system without changing how they store, hold, or access their XRP. The concern stems from how transactions are authorized on the network. When users sign transactions through their cryptocurrency wallets, their public keys can become exposed, potentially creating an attack vector if sufficiently advanced quantum computers emerge.
Such technology could eventually undermine existing cryptographic protections, putting accounts with exposed public keys at risk. The XRP Ledger Foundation’s proposed solution is designed to address this vulnerability before quantum computing advances to the point where such attacks become practically achievable.
Beyond the additional protection, the proposal has another notable selling point: affordability. Users would not have to pay higher transaction fees to benefit from the enhanced security. In other words, XRP holders could strengthen their accounts against emerging quantum threats without incurring additional transaction costs, making the proposed upgrade particularly appealing to the community.

Although the upgrade has not yet gone live, the team has outlined its next steps, with a migration study planned for the first half of 2027. The research will explore how existing XRPL accounts can move to the new quantum-resistant security framework, including the transition process and what account holders would need to do to adopt the upgraded protection.
Developers are also addressing discrepancies in how the proposed system generates cryptographic keys across its Python, JavaScript, and server implementations, a necessary step toward ensuring consistent and reliable performance across the network.
As <a href="https://zycrypto.com/ripple-unleashes-bold-plan-to-make-xrp-fully-quantum-resistant-by-2028/" rel="noopener noreferrer nofollow">ZyCrypto previously reported</a>, Ripple has outlined a comprehensive four-phase roadmap to make the XRP Ledger, its decentralized Layer-1 blockchain, resistant to potential quantum computing attacks, with full quantum readiness targeted for 2028.
