Key highlights:
- The Algorand Foundation has unveiled plans for a quantum-safe security upgrade.
- The initial phase will begin in the third quarter of 2026, with the upgrade expected to be completed by 2027.
- Ethereum, Solana, Ripple, Stellar, and other major platforms have also unveiled similar plans.
As the crypto industry grows increasingly cautious about the future risks posed by quantum computers, more blockchains are embracing security measures. The latest to join the trend is the Algorand Foundation, which unveiled a roadmap to make its infrastructure quantum-resistant by 2027.
Notably, the Algorand ecosystem is planning a major security upgrade involving accounts, wallets, custody solutions, and the core network. While the first phase will begin in the third quarter of 2026, the upgrade is expected to be completed by next year.
Algorand rolls out multi-phase quantum-resistant plan
The Algorand Foundation has rolled out a detailed roadmap as part of its plan to make the infrastructure quantum-resistant by 2027. The security upgrade will take place in multiple stages, with the first phase beginning by 2026 Q3.
Quantum computers won’t wait for the industry to catch up.
Algorand began preparing in 2022, and Falcon post-quantum signatures are already live on Mainnet.

The earlier phase includes the launch of post-quantum accounts, support for quantum-safe multisignature wallets, and staking from upgraded accounts. In the following stages, the team plans to strengthen deeper parts of the blockchain. This will further secure the entire network against potential quantum computing risks.
Despite the security upgrade, Algorand confirmed that the network will not completely abandon the existing cryptography. Instead, the ecosystem is embracing a hybrid approach that combines traditional encryption with newer quantum-resistant protections. This will help users to protect themselves from quantum computers, while also remaining safe from current cybersecurity threats.
Strengthening the core network security system
Algorand’s quantum-resistant upgrade targets the core network security system. One of the main focuses is the system’s Verifiable Random Function (VRF). As VRF plays a key role in maintaining the security and decentralization of the network, the team intends to keep it quantum-safe. Chief Scientific Officer Chris Peikert and his team will lead this project, and the quantum-resistant VRF solution is expected by early 2027.
The platform is also testing Falcon-based cryptographic tools. This is to strengthen the consensus process that confirms and finalizes transactions. In addition, the team is also exploring Falcon-512 to reduce extra storage demands.
Fears of Q-Day drive blockchain industry’s security push
It is worth noting that the move comes amid growing concerns about “Q-Day.” It is a future point when quantum computers could become powerful enough to break the encryption systems. Today, all blockchains and digital networks are secured by these encryption systems. Since 2022, Algorand has been preparing to strengthen its security system.
Bruno Martins, Chief Technology Officer, Algorand Foundation, stated,
“Post-quantum security cannot be retrofitted after Q-Day. Every institution tokenizing or staking, every developer building, and every user transacting on Algorand needs to know their assets will remain secure should the quantum threat materialize. This roadmap gives them that assurance, starting with concrete deployments in 2026.”
Interestingly, Algorand’s move comes on the heels of similar initiatives by other major blockchain platforms. For example, Stellar has recently unveiled a plan to go quantum-resistant by 2027.
