The Layer-1 blockchain Algorand has presented a plan to secure its network against the risks posed by quantum computers by the end of 2027. The first measures are scheduled to begin in the third quarter of 2026.
“The question is no longer whether the transition to quantum-safe cryptography will happen. The question is whether organizations will be prepared for it,” the Algorand Foundation wrote in its recently published roadmap.
Algorand has been preparing since 2022
According to the Foundation, Algorand has been working on the issue for several years. Back in 2022, the network introduced so-called State Proofs based on the Falcon signature scheme. This technology is intended to enable quantum-resistant proof of the blockchain’s state.
Algorand is now planning the next step. In the future, native Falcon-1024 accounts are expected to be introduced. They will offer the same functions as regular wallets but use cryptography specifically designed for the era of quantum computers. Support is planned for AlgoKit, developer SDKs, and the Pera wallet.
The Foundation is also evaluating additional signature schemes such as ML-DSA. In the long term, users should be able to choose between different security models.
Hybrid approach for greater security
Algorand currently considers a complete switch to new methods premature. The Foundation points out that quantum-resistant cryptography has not yet undergone the same level of real-world testing as established systems.
Therefore, the project is relying on hybrid accounts. These combine traditional elliptic-curve cryptography with the Falcon scheme, aiming to reduce risks on both sides.
“We are not marching blindly forward,” the roadmap states. Instead, the project is working on a “cryptographically agile” network with multiple layers of protection.
In addition to accounts, other protocol components are also on the agenda. These include the VRF random function, which plays a central role in the consensus mechanism, as well as validator signatures. For both areas, Algorand plans to develop quantum-resistant alternatives by 2027.
Conclusion:
Algorand’s roadmap shows a proactive approach to quantum computing risks by combining Falcon signatures, hybrid accounts, and future support for alternative schemes such as ML-DSA. The gradual rollout may help the network strengthen long-term security without abandoning proven cryptographic systems too quickly.
