After establishing Solana’s post-quantum migration roadmap, the core development team has selected the Falcon signature scheme

According to an April 27 article on the Solana Foundation’s official blog, after independent research, the core development teams Anza and Firedancer have both selected Falcon as the network’s post-quantum digital signature scheme. The two teams have each published initial implementation versions on GitHub. The Solana Foundation also simultaneously released a post-quantum migration roadmap consisting of three phases, stating that the migration is not expected to cause significant impact.

Background on Falcon selection: NIST recognition and independent consensus from both teams

According to the Solana Foundation’s official blog, Solana currently uses the Ed25519 elliptic curve signature scheme to authorize transactions, which faces the risk of attacks via the Shor algorithm in environments with sufficiently powerful quantum computers.

Both core development teams, Anza and Firedancer, conducted independent research and reached the conclusion that Solana should adopt the Falcon post-quantum scheme. They have published initial implementation versions on GitHub. Falcon is designed based on lattice cryptography and has been selected for NIST’s post-quantum cryptography standards. Its computational efficiency meets the encryption overhead limits of Solana’s high-throughput network architecture.

In the official blog, the Solana Foundation cites: “The overall adjustments around Falcon reflect extensive research into Solana’s quantum resilience. We have a clear and thoroughly researched plan that we can initiate when the time is right. The migration work is controllable, the transition can be completed quickly, and it is not expected to significantly affect network performance.”

Solana post-quantum three-step migration roadmap

According to the plan published by the Solana Foundation’s official blog, the post-quantum migration will be carried out in three stages:

First stage: Researchers continue to evaluate Falcon and other alternative schemes

Second stage: New wallets adopt the post-quantum signature scheme first

Third stage: Existing wallets complete migration to the post-quantum standard

At the ecosystem level, Blueshift’s Winternitz Vault has been live and operating for more than two years. In a research paper published by Google Quantum AI in 2026, Winternitz Vault is listed as a “benchmark example of industry-leading work in the post-quantum era.”

Blockchain post-quantum progress: Algorand mainnet deployment and TRON plans

According to publicly available information, in November 2025, the Algorand Foundation protocol team completed the first post-quantum transaction on the Algorand mainnet, deploying the Falcon signature scheme directly on the mainnet.

TRON founder Justin Sun announced that TRON plans to enable an anti-quantum network on the mainnet in Q3 2026.

Frequently Asked Questions

Why did Solana choose Falcon instead of other post-quantum schemes?

According to the Solana Foundation’s official blog, Falcon has been selected for NIST post-quantum cryptography standards, and its design based on lattice cryptography offers high computational efficiency, meeting Solana’s encryption overhead limits for a high-throughput network. After independent research, both core development teams, Anza and Firedancer, reached the same conclusion, further confirming Falcon’s technical suitability.

How many phases are included in the Solana post-quantum migration plan?

According to the roadmap published by the Solana Foundation, the migration is carried out in three phases: continuous evaluation of alternative schemes, new wallets adopting the post-quantum scheme, and existing wallets completing migration to the new standard. In the official blog, the foundation stated that the migration is not expected to have a significant impact on network performance.

Which blockchain networks have already advanced with post-quantum deployments or announced related plans?

According to publicly available information, Algorand completed its first post-quantum transaction on the mainnet in November 2025 (using the Falcon scheme); Solana has published initial Falcon implementations and established a three-step migration roadmap; TRON founder Justin Sun announced plans to enable a mainnet anti-quantum network in Q3 2026.
