The Solana Foundation has partnered with Project Eleven to test quantum-resistant transactions on a production-like testnet

Project Eleven conducted a full quantum threat assessment on Solana’s infrastructure, including user wallets, validator identities, and risks like “harvest now, decrypt later” attacks.

The team prototyped a functioning testnet with post-quantum signatures, showing no major performance trade-offs despite the higher computational demands of these algorithms.

The pilot demonstrates that end-to-end post-quantum digital signatures are practical and scalable for the network.

“Quantum computers aren’t here yet, but Solana Foundation is preparing for the possibility,” said the Solana Foundation in a post on X

Experts predict varied timelines for cryptographically relevant quantum computers capable of breaking elliptic curve signatures used by major blockchain networks today.

Ethereum co-founder Vitalik Buterin has warned elliptic curves could fail before 2028, while Blockstream CEO Adam Back doesn’t see risks materializing for another 40 years.
