Solana Foundation said the network has a researched path to migrate toward post quantum cryptography if quantum computing becomes a credible threat to blockchain security.
A new report on Solana’s quantum readiness is here, from @anza_xyz and @jump_firedancer.
TLDR: Quantum is still years away, and if and when it materializes, the work to migrate Solana is well-researched, understood, and ready to deploy as described below. pic.twitter.com/eNYgJeV2mx

The foundation said no immediate change is needed, but the ecosystem has already studied how to protect wallets and preserve network performance.
The plan centers on Falcon, a post quantum digital signature scheme identified independently by Anza and Firedancer, two major Solana validator client developers. Both teams have built initial Falcon implementations, reflecting alignment around compact signatures designed for high throughput blockchain use.
Solana Foundation also pointed to Blueshift’s Winternitz Vault, a quantum resistant lamports vault that uses Winternitz one time signatures and has been available in the ecosystem for over two years. The project’s GitHub describes the vault as using WOTS and truncated Keccak256 hashing to protect against quantum related threats.
The roadmap calls for continued research into Falcon and alternatives, adoption of a post quantum scheme for new wallets if the threat becomes credible, and migration of existing wallets to the selected standard. Solana Foundation said the transition is expected to be manageable and not meaningfully affect network performance.
