Algorand sets a deadline: full post-quantum network protection by the end of 2027
The Algorand Foundation has unveiled an ambitious roadmap aimed at achieving "broad quantum resilience" for the network by the end of 2027. The first key protocol updates are scheduled for the third quarter of 2026. This is not just a plan — it is a response to a real threat confirmed by recent Google Quantum AI research, which shows that future quantum computers will be able to break elliptic curve cryptography with far fewer resources than previously thought.
The Foundation Has Already Been Laid
It is important to note that Algorand is not starting from scratch. Preparations for the post-quantum era began back in 2022 with the introduction of State Proofs — compact ledger state certificates signed using the Falcon scheme every 256 rounds. In November 2025, the team conducted the first mainnet transaction authorized by Falcon signatures, using the LogicSig programmable authorization mechanism. This was an important technological demonstrator, but it required workarounds.
Plan for 2026-2027: From Hybrid Accounts to Quantum-Resistant Consensus
The real breakthrough will occur in the third quarter of 2026. Algorand will gain native support for post-quantum accounts. This means users will be able to create Falcon-1024 accounts directly from a standard 25-word seed phrase, without any technical workarounds. The network will maintain compatibility with Ed25519 but will add support for Falcon-512, ML-DSA, and other schemes. A key feature will be hybrid accounts, combining classical and post-quantum keys for a smooth transition.
By the end of 2026, the foundation will implement native multi-signature support for multiple cryptographic schemes and begin migrating its own treasury to post-quantum addresses. However, the most challenging task is consensus. Currently, committee member selection and message signing rely on VRF and Ed25519, which are vulnerable. The foundation plans to present a research paper on post-quantum VRF by early 2027, and a hybrid model using both Ed25519 and Falcon is being considered for consensus messages.
"Post-quantum security cannot be patched after Q-Day," rightly notes Algorand Foundation CTO Bruno Martins. And it is impossible to argue with that.
My analysis: Algorand's plan looks like one of the most well-developed and realistic in the industry. They are not just reacting to the threat but systematically restructuring the architecture, from accounts to consensus. However, it is worth remembering that the timelines and set of solutions are predictive in nature and may change as post-quantum cryptography standards evolve. Unlike BNB Chain, where experiments revealed a significant performance drop, Algorand appears to be betting on hybrid models to minimize speed trade-offs. This is the right, albeit more complex, path.
