Algorand puts an end to the quantum race: full network protection by 2027
Quantum computing is ceasing to be a futuristic threat and is becoming a matter of the next few years. Recognizing this, the Algorand Foundation has presented an ambitious yet clearly structured plan for the complete migration of its blockchain to quantum-resistant cryptography. The key goal is to ensure absolute network protection against attacks using quantum computers by the end of 2027.
Why is this critically important? The main enemy of modern cryptography is Shor's algorithm. A sufficiently powerful quantum computer could compute a private key from a public one in minutes, making millions of wallets operating on elliptic curves vulnerable. Recent research by Google has shown that such an attack would require about 1,200 logical qubits — a figure that no longer seems unattainable. Algorand is not waiting for the threat to become reality; it is acting proactively.
What has been done and what is planned
The foundation was laid back in 2022 with the introduction of State Proofs technology — "snapshots" of the network state resistant to quantum attacks. Since then, the network has processed over 140,000 such transactions. The protection is based on the Falcon signature scheme — one of the new post-quantum standards, notable for its compact signature size, which is critical for saving bandwidth.
The next stage is the implementation of native Falcon-1024 accounts. Support is already being prepared by Pera Wallet and developer tools. Such an account can be created using a familiar 25-word mnemonic phrase. However, the key innovation will be hybrid accounts, combining a classic elliptic curve signature and the new Falcon signature. This will provide double protection: against both traditional and quantum attacks, acting as insurance in case vulnerabilities are found in the new methods.
The most challenging tasks are the modernization of the consensus mechanism and the Verifiable Random Function (VRF), which determines who validates blocks. Both currently rely on classical cryptography. The foundation's scientific director, Professor Chris Peikert, plans to present research on quantum-resistant VRF as early as the beginning of 2027. By the end of 2026, Algorand will also add multi-signatures, staking support from secured accounts, and a more compact Falcon-512 variant.
Analyst's opinion: Algorand demonstrates a level of foresight rare for the industry. While many projects ignore the problem, hoping for the best, Algorand is investing resources in protection that will become the standard in 5-10 years. This is not just a technical update — it is a strategic move that could make Algorand one of the most secure and reliable blockchains in the post-quantum era.
