Quantum Computing Confronted? Teams Algorand (ALGO) has just achieved the world’s first secure transaction attacks of quantum computers to its main network. This was done with the help of signatures of FALCON of the selected standard NIST (US National Institute of Standards and Technology). Let’s try to explain this one cryptographic progress in plain language.
Le Journal du Coin brings you this promotional article in collaboration with Algorand.
Key points of this article:
- Algorand completed its first quantum-resistant blockchain transaction.
- FALCON signatures chosen by NIST offer the post-quantum security needed for the future of blockchains.
November 3, 2025 crypto project team Algorand explained in a press release what they did the first “post-quantum” transaction i.e rack to quantum computers.
This real transaction, visible on the Algorand public blockchain, shows that it is already possible to protect digital assets from future threats from quantum supercomputers without disrupting the day-to-day operations of this decentralized network.
Since the 1990s, researchers such as Peter Shore, demonstrated that quantum computers could one day break modern encryption systems, based on complex mathematics such as factoring large numbers. This applies to common tools such as RSA or elliptic curves used to sign transactions.
Because the risk is almost no longer theoretical: experts, in particular Vitalik Buterin (co-founder of Ethereum), evaluate the chances of having a powerful quantum computer until 2030 (less than 5 years!) 20% .
Finding a cure before harm is possible: FALCON signatures Blockchain networks are particularly vulnerable because it all depends on digital signatures to confirm transactions and consensus. Therefore, a quantum computer can ” forge blocks, steal funds or rewrite transaction history “, as stated in the press release.
Systems like Algorand, designed for decades of service, should provide this technological shift to remain reliable. This is where they come to the rescue FALCON signatures . selected NIST in 2022, they offer a level of security equivalent to current standards (such as AES-128), but resistant to quantum attacks .
Based on mathematics lattice-based signatures, these digital signatures are resistant to algorithms such as Shor. Their main advantage ? They compact and quickly checked which makes them perfect for blockchains where validator nodes need to quickly process thousands of transactions without wasting resources.
In Algorand, these signatures integrate seamlessly by means of convenient tools for developers and users. For example, you can create a secure account, top up and send money using FALCON signatures, and all without changing the basic rules of the network . Advantages the obvious ones: accounts and transaction histories stable to quantum attacks, without increase network load.
In summary, this progress transforms post-quantum cryptography to tangible reality . It not only protects current users but and prepares the blockchain ecosystem to a future where quantum computers will become commonplace. In the long run, this paves the way for interchain transactions protected by this reliable FALCON signature standard.
