The Algorand Foundation has released a quantum-resistant security roadmap, planning to make most key components of the public blockchain quantum-resistant by 2027. The first upgrades will begin in 2026, covering the account system, multi-signature wallets, and staking support, followed by upgrades to the underlying protocol components.

In 2026, I will first change my account and wallet.

According to Algorand's plan, quantum-resistant accounts, quantum-resistant multi-signature wallets, and related staking support will be launched first in 2026. This phase mainly focuses on the user side and frequently used functions, migrating account security and basic operations to the new cryptographic system first.

The next phase will expand the protection to more core parts of the protocol. The foundation states that the goal is to achieve "broad quantum resilience" by the end of 2027, meaning that not only will the wallet layer be upgraded, but the underlying network will also be able to adapt to the new security standards.

Migration is more than just changing your wallet

Algorand points out that switching an operational blockchain to quantum-resistant cryptography presents challenges not only for user wallets but also for the protocol infrastructure itself. On-chain accounts, signature methods, verification processes, and some core modules may all require gradual adjustments.

The foundation also mentioned that this work did not just begin recently. Its quantum-resistant research dates back to 2022, and the roadmap announced this time expands that work from local to the entire protocol level.

Ethereum and Solana are also preparing

Quantum security has become a long-term issue for several mainstream ecosystems. The Ethereum Foundation announced a dedicated quantum-resistant security initiative earlier this year, focusing on how wallets, applications, and validators can migrate. Solana developers have also proposed solutions, discussing how to drive users and networks to switch to quantum-resistant cryptographic systems in the event of escalating threats.

In the broader technology field, Google has reminded organizations to prepare for quantum-resistant cryptography migrations as early as possible, setting a goal of completing some infrastructure upgrades by 2029. The National Institute of Standards and Technology (NIST) is also advancing the standardization of quantum-resistant algorithms and setting a timetable for phasing out some older cryptographic systems.

Chris Peikert, Chief Science Officer of the Algorand Foundation, stated that migrating protocols to online environments typically takes several years, and as the latter half of this decade approaches, the probability of traditional cryptographic systems facing quantum attacks will increase significantly. Therefore, preparations need to begin well before the so-called "Q-Day," which refers to the hypothetical point in time when a quantum computer first gains the ability to break existing digital asset encryption systems.
