XRP ledger goal: Achieve comprehensive anti-quantum capabilities by 2028, leading Ethereum

XRPL developer goal: Achieve full quantum resistance by 2028

The development team of XRP Ledger (XRPL) plans to achieve full resistance to quantum computing threats by 2028 through hybrid cryptography, native key rotation, emergency protection mechanisms, and extensive network audits. According to XRPL Foundation contributor Vet, the development team is expected to make significant progress and launch an initial hybrid deployment plan in 2027. Vet is also the operator of an XRPL verification node in the decentralized unique node list (UNL).

This timetable will allow XRPL to complete the transformation of full quantum-resistant one year ahead of the planned transition in Ethereum, which aims to be achieved by December 2029. However, both networks are being laid out in advance because no one currently can accurately predict when quantum computers will pose a substantial threat to existing encryption systems.

Native key rotation reduces operational risk

XRPL developers plan to make "native key rotation" an important part of their broader security strategy. This feature allows users to update their encryption keys while retaining existing r addresses. Therefore, hosting providers and individual holders do not need to transfer XRP to newly created wallets during the transition period. This design is expected to reduce errors, confusion and security risks in the operation of exchanges, payment companies and institutional custody platforms.

Hybrid security deployment ensures transition stability

In response to the sudden progress that quantum computing may bring, developers are preparing an Incident Response Service system called the "Quantum-Day protocol." This mechanism can isolate vulnerable accounts and place them in a protected state without shutting down the entire ledger.

In addition, the development team has begun testing post-quantum algorithms under actual network conditions. During the hybrid deployment phase of the new plan, the new security protocols will run in parallel with existing encryption systems. This parallel structure helps developers assess performance, identify technical weaknesses, and introduce stronger protections without affecting regular transactions. Testing will also focus on the impact of the new signature mechanism on verification nodes, applications, wallets, and other critical network infrastructure.

Compared with Algorand highlights industry competition

At the same time, Algorand has provided quantum security protection for some accounts by using the Falcon-1024 signature algorithm. But Vet cautioned that Algorand's current architecture should not be described as fully quantum-resistant. Most regular Algorand operations still rely on the Ed25519 signature, which may pose a risk of being cracked in the face of quantum computers. Under its current implementation, consensus systems also lack complete post-quantum protection.

Vet pointed out that Algorand expects to further integrate its network in 2027. Therefore, the core of this competition is comprehensive network protection, rather than security hardening for specific accounts or transaction types. In contrast, Ripple's strategy involves the "Project Eleven" initiative and extensive security assessments covering every layer of XRPL. Auditors will conduct a detailed review of verification nodes, cryptographic signatures, network infrastructure, account security and transaction processing before the final upgrade.

The development team plans to run both traditional signatures and post-quantum resistance signatures during the testing phase in 2027. This approach should provide compatibility guarantees as wallets, exchanges and infrastructure providers update their systems. If testing and auditing meet the required security standards, XRPL plans to complete the main network upgrade in 2028, allowing for the transition. The roadmap establishes long-term cryptographic protection as a core priority for network technology development.
