One XRP Ledger user has proposed a hybrid post quantum testing for 2027 as well as a mainnet switchover in 2028. Neither date was confirmed by the XRPL roadmap.
The following is a summary of the information that you will find on this page.
- One XRPL Foundation member has set a target for 2028 to transition from the mainnet and 2027 to hybrid testing.
- Currently there’s no official XRPL roadmap to confirm the 2028 deadline proposed by contributors.
- XRPL supports Ed25519 and secp256k1 signatures.
- RegularKey allows XRPL users to maintain their public address while changing signing keys.
- Justin Drake, a researcher at Ethereum, believes that the three cryptographic layers of Ethereum will be post-quantum safe by 2029.
Vet, a XRP Ledger Foundation member and validator for the decentralized Unique Node List (DUNL), presented the dates. Sept. 9 post on X. This contributor described a testing phase that would be followed by a system hybrid in which both conventional signatures and quantum-resistant ones could operate simultaneously.
According to the proposed timeline, XRPL would receive a quantum upgrade one-year before 2029 as discussed by Ethereum researcher Justin Drake. No date is a guarantee of network activation. The Ethereum schedule is based on a technical presentation by a researcher, whereas XRPL dates are not included in any official amendments, specifications, validator votes or roadmaps.
XRP Ledger’s target of 2028 remains a proposal for contributors
Vet said developers expect major progress in 2027 before a possible mainnet transition during 2028. This work includes testing new post-quantum cryptography and signatures alongside XRPL’s current cryptography.
The Public Materials official XRP Ledger website Do not identify 2028 currently as an approved date. As of Sept. 10, XRPL has not yet published an amendment proposal, technical specification, or implementation calendar.
It is left to the contributors’ expectation that they will be able to report dates. XRPL modifications are normally subject to public testing, development and voting on amendments before they can be activated. A posting on X does not activate the protocol code nor commit validators participating to a deployment schedule.
Vet called a proposed emergency system a “Quantum-Day” response. In the description of the vulnerability, the accounts were isolated and put into a state protected without having to stop the ledger. The public XRPL documents reviewed in this report do not include an amendment with that name.
At this time, no technical specifications explain its activation requirements, account restrictions, or recovery process. Until these developers release those details, it is still an attributed idea and not a XRPL confirmed feature.
The key rotation that is in place does not allow for quantum migration
The XRP Ledger recognizes both algorithms. Secp256k1, which is based on Elliptic Curve Digital Signature Algorithm and Ed25519 uses Edwards-curve Digital Signature Algorithm. The ledger recognizes both. cryptographic key documentation.
XRPL documentation admits that a quantum computing device with Shor’s algorithm capable of performing at a high enough level could pose a threat to its current signature systems. On the same page, it is stated that developers may introduce a new signing algorithm in case quantum computers become practical. The page does not specify a post-quantum implementation date or a specific algorithm.
RegularKey is a built-in mechanism that allows an account to assign a new signing key, without having to change its public address. The account’s RegularKey can be replaced or removed by submitting a transaction authorized, according to XRPL. key-management tutorial.
RegularKey rotation does not equal complete quantum protection. A XRPL-account retains a key derived directly from the original credentials. The protocol allows users to disable this key, but not replace. The migration process would have to include master keys, transactions verification, validater operations, and multisignature list.
Vet suggested that users and administrators would be less disturbed if existing r’addresses were preserved. Documentation confirms the fact that a RegularKey is assigned and leaves account addresses unchanged. The same mechanism is not sufficient to provide network-wide transition post-quantum.
Ethereum’s 2020 date includes three different technical layers
Compare Ethereum with Justin Drake’s published quantum plan. Drake identifies three areas that require new cryptography. These are BLS signatures when in consensus, KZG data commitments and ECDSA signed accounts.
“My completion date for Ethereum being fully post-quantum secure is 2029,” Drake. Drake said that the year was his anticipated completion date, and not an activation approved by Ethereum governance.
Ethereum has different algorithmic components and protocols than XRPL. The comparison of calendars does not reveal which network is more advanced in terms of engineering, security testing and review. A technical benchmark is not cited as a common measure of readiness by either project.
Drake has placed his own personal estimate. “Q-Day,” Quantum computers will be able to break public key cryptography in 2032. The researchers have yet to establish a date that can be verified for such a device. The hardware progress, the error correction capabilities and resources needed to hack a blockchain key are still uncertain.
A quantum upgrade to XRPL would need validator support
Before a change in protocol can be implemented, XRPL validaters must continuously support the amendment above the threshold. For the network to amend its protocol, it requires that more than 80% of trusted validators support an amendment for at least two weeks.
Recent upgrades have shown how activation can be delayed. As crypto.news reported, XRPL’s corrected BatchV1_1 amendment received 24 votes from 35 dUNL validators On Sept. 8, As its support of 68.57% was still below the activation level, the countdown to two weeks could not start.
Developers would need to first publish the code, and then define which signature scheme is supported. Testing will need to include a review of transaction size, speed of verification, performance and compatibility between hardware and wallets, as well as account recovery procedures. Validators would then be able to decide whether or not the change is enabled.
The public profile of the contributor does not identify an algorithm. Candidates have different operating costs. Larger signatures and public keys can increase storage, processing and bandwidth needs, while errors in implementation can undermine a cryptographic system that is otherwise secure.
Standardized algorithms allow for multiple paths.
In 2024, the U.S. National Institute of Standards and Technology will publish its first post-quantum standard. These include ML-KEM, which stands for key establishment. ML-DSA for digital signatures SLH – DSA as a signature standard based on hashing
XRPL will require a digital signature method, as users would sign transactions while validators check authorization. The selection of a standard algorithm will still require engineering specific to the network, independent audits, and compatibility tests.
Project Eleven maintains a post-quantum cryptography registry It covers Falcon-related schemes, such as MLDSA. SLHDSA. and FNDSA. This website is open to the public. post-quantum audits and testing tools. But no public announcement examined for this report confirms a XRPL or a security audit.
