XRP Ledger (XRPL) developers have joined the global technology race, officially aiming to make the ledger fully quantum-resistant by 2028. According to Vet, an XRPL Foundation contributor and validator on the decentralized Unique Node List (dUNL), major progress and the launch of a hybrid deployment of new security protocols are expected as early as 2027.

The announced timeline puts XRP Ledger ahead in the industry-wide race: the network plans to complete the transition one year earlier than its key competitor, Ethereum, whose equivalent roadmap extends through 2029.

Experts point to three key architectural features as XRPL's main technological advantage in this migration:
- Native key rotation: XRPL's architecture will allow cryptographic keys to be updated while fully preserving existing r-addresses. This eliminates the risk of panic and confusion among custodians. On most other blockchains, the transition to post-quantum standards will require users to manually transfer their assets to new wallets.
- The "Quantum-Day" emergency response protocol: In the event of an unexpected technological breakthrough by quantum computer developers, XRP Ledger and RippleX developers have introduced a contingency plan. It will allow vulnerable accounts to be instantly isolated and moved into a secure mode without shutting down the ledger itself.
- Active cryptography testing: Developers have already begun practical testing of quantum-resistant algorithms. The new security protocols will be deployed through a hybrid approach, operating alongside the existing system and allowing security to be scaled without disrupting the network.
How XRPL is challenging Algorand and preparing for a network audit
Against this backdrop, the crypto community has renewed its debate over technological leadership with Algorand, which has reported the launch of quantum-secured accounts based on Falcon-1024 signatures. Vet urged the community not to overstate this achievement, noting that Algorand's architecture is currently only partially protected.
Quantum secure accounts is just one part, Algorand is not fully quantum ready either. Lots of Ed25519 use on the network.
That's why Project 11 is looking into Validators and other parts of the XRP Ledger as well to assess where we need to work on.
According to him, the network still relies heavily on the vulnerable Ed25519 standard for most everyday operations, while the full integration of quantum protection, including the consensus mechanism, will not be completed before 2027.

Meanwhile, Ripple's comprehensive strategy and the Project Eleven initiatives involve a complete security audit of every layer of XRP Ledger, from validators to network infrastructure.
The comprehensive plan includes a testing phase, the hybrid use of old and new signatures in parallel in 2027, and the final mainnet upgrade in 2028.
