Jump Crypto, the team behind Firedancer, stated that Falcon uses the most compact signatures among NIST standards. This may help maintain high network throughput for Solana.
The two main validator clients in the Solana network have started testing a new signature solution called Falcon. It is designed to protect the network from future threats posed by quantum computers.
The Anza and Firedancer teams reported that the solution is intended for high-load networks. If necessary, it can be quickly enabled, for example, when quantum computers begin to break current cryptography.
«The transition does not seem complicated; it can be carried out fairly quickly without seriously affecting the network's operation.»
Concerns about quantum computers are growing. There is increasing discussion about how to protect private keys and wallets in the future.
The main task now is to implement such solutions without unnecessary load on the network and without loss of speed.

At Jump Crypto, which is behind Firedancer, it was stated that Falcon-512 was created with this in mind. According to them, it produces the most compact signatures among post-quantum standards selected by the U.S. National Institute of Standards and Technology.
The company also noted that verifying Falcon signatures does not require complex implementation, and the signing process itself is performed off-chain.
The Solana Ecosystem Prepares for Quantum Risks
At Anza and Firedancer they reported that they independently recognized the need to implement post-quantum solutions, after which they coordinated the development of Falcon.
Both validator clients have already added the first version of the solution to their repositories on GitHub. According to Anza, work on Falcon has been ongoing since at least January 27, 2026.
At the same time, Falcon is not the first solution of its kind in the Solana ecosystem. Back in January 2025, Blueshift introduced Winternitz Vault, which provides protection against quantum threats. However, this is an optional tool for users, not a protocol-level update.
Amid discussions about Falcon the topic of quantum risks has resurfaced. Researchers from Google and the California Institute of Technology believe that working quantum computers may appear earlier than previously predicted.
Moreover, they may need less computing power to break cryptography than previously thought.

At Google they went even further and stated that under certain conditions, quantum systems could break Bitcoin's protection in just a few minutes. In this case, there is a risk of an attack right at the moment of the transaction.
But not everyone shares this view. Blockstream CEO Adam Back believes that the real capabilities of quantum computers are greatly overestimated. According to him, for now, these are more laboratory developments than a technology capable of posing a threat in the coming years.
