The Algorand Foundation has unveiled a quantum-resistant roadmap, aiming to equip the majority of critical components on this public blockchain with quantum resistance by 2027. The first upgrades, beginning in 2026, will cover the account system, multisig wallets, and staking support, followed by enhancements to underlying protocol components.
In 2026, update your account and wallet first.
As planned by Algorand, quantum-resistant accounts, quantum-resistant multisig wallets, and associated staking support will be launched in 2026. This phase primarily focuses on user-facing features and common functionalities, migrating account security and basic operations to the new cryptographic system.
In subsequent phases, the protection scope will be expanded to cover more core components of the protocol. The foundation aims to achieve “broad quantum resistance” by the end of 2027, meaning not only will the wallet layer be upgraded, but the underlying network will also adapt to new security standards.
Migration involves more than just changing wallets.
Algorand notes that transitioning a live blockchain to quantum-resistant cryptography presents challenges not only in user wallets but also in the protocol infrastructure itself. On-chain accounts, signing methods, verification processes, and certain core modules may all require gradual adjustments.
The foundation also noted that this work did not begin recently; its quantum-resistant research dates back to 2022, and the newly announced roadmap expands prior efforts from a localized scope to the entire protocol level.
Ethereum and Solana are also preparing.
Quantum security has become a long-term priority across multiple major ecosystems. Earlier this year, the Ethereum Foundation announced a dedicated quantum-resistant security initiative, focusing on how wallets, applications, and validators can migrate. Solana developers have also proposed related solutions, discussing how to transition users and the network to quantum-resistant cryptography as threats increase.
In the broader technology field, Google has advised organizations to begin preparing for quantum-resistant cryptography migration early, with a goal of completing part of their infrastructure upgrades by 2029. The U.S. National Institute of Standards and Technology (NIST) is also advancing the standardization of quantum-resistant algorithms and establishing timelines for phasing out legacy cryptographic systems.
Chris Peikert, Chief Scientific Officer of the Algorand Foundation, stated that protocol migrations online typically take years, and as the latter half of this decade approaches, the probability of traditional cryptographic systems facing quantum attacks will rise significantly. Therefore, preparations must begin well before the so-called “Q-Day”—the hypothetical point at which quantum computers first gain the capability to break existing cryptographic systems for digital assets.
