Algorand aims for quantum resistance across network by 2027

Transition planned for 2026

According to the roadmap, initial steps will begin in 2026. At this stage, post-quantum accounts, multi-signature wallets, and staking features will be introduced. Subsequent phases will focus on expanding protection to the core protocol components of the network.

“Migrating a live protocol takes years, and as we near the end of this decade, the likelihood of quantum attacks on legacy cryptographic methods increases significantly,” cautioned the Foundation’s Chief Scientist Chris Peikert.

Chris Peikert emphasized that transitioning to quantum-resistant standards is not a process that can be completed quickly. The Foundation described the plan as a continuation of initiatives launched in 2022, aiming to achieve network-wide quantum resilience by the close of 2027.

Growing industry response

Currently, most major blockchains rely on elliptic curve cryptography to protect wallets and transactions. While this method is considered secure today, there are concerns that it could be vulnerable to sufficiently advanced quantum computers. Although experts agree such quantum machines do not yet exist, government agencies, technology firms, and crypto projects are already developing long-term transition strategies.

Mini glossary: Post-quantum cryptography refers to next-generation encryption methods designed to withstand attacks by powerful quantum computers. NIST, the US National Institute of Standards and Technology, leads standardization efforts in this field.

Google has advised institutions to begin preparations for post-quantum cryptography and has already incorporated quantum-safe standards into parts of its infrastructure, aiming for completion by 2029. Meanwhile, NIST is standardizing post-quantum algorithms and establishing timelines to phase out outdated cryptographic systems.

Ethereum and Solana take similar action

Quantum readiness is quickly becoming a strategic issue across the crypto ecosystem. This year, the Ethereum Foundation initiated a dedicated post-quantum security effort, focusing on safe transitions for wallets, apps, and validators. Developers in Solana have also published proposals outlining how users and the network could migrate to quantum-resistant encryption if the threat becomes more pressing.

Algorand Foundation emphasized that blockchain networks should prepare well in advance of so-called “Q Day”—the hypothetical moment when a quantum computer can break the encryption securing digital assets.

The Foundation noted that upgrading a live blockchain to post-quantum cryptography will require changes not only to user wallets but also to core protocol components, making early preparation critical.

The Foundation’s timeline aims to complete the transition before NIST’s scheduled deprecation of some legacy cryptographic standards. The goal is to achieve this milestone three years ahead of the timeframe set by the US National Security Agency for securing national security systems.
