On December 16, 2025, the Solana Foundation announced a collaboration with Project Eleven, a post-quantum security firm, to test quantum-resistant digital signatures on a dedicated Solana testnet, per Cointelegraph and PRNewswire. This marks a concrete step toward protecting the network from future quantum computing threats, with end-to-end quantum-resistant transactions proven practical and scalable using current technology. Matt Sorg, Solana Foundation’s VP of Technology, stated the initiative ensures Solana remains secure “decades into the future,”
Project Eleven conducted a comprehensive quantum threat assessment covering wallets, validators, and core infrastructure, then deployed a functioning post-quantum signature system on the testnet. Results show quantum-resistant transactions maintain Solana’s high throughput without performance loss, despite post-quantum cryptography’s higher computational demands. This builds on Solana’s earlier Winternitz Vault (January 2025), an optional hash-based signature feature for user funds.
Following Solana, Aptos proposed AIP-137 on December 18, 2025, to add optional SLH-DSA (NIST-standardized FIPS 205) post-quantum signatures, per Cointelegraph and GitHub. If approved via governance, it enables quantum-resistant accounts without network migration, keeping Ed25519 as the default. Aptos Labs emphasizes conservative security with hash-based schemes.
Quantum computers could break elliptic curve cryptography (e.g., Ed25519) using Shor’s algorithm, risking wallet theft and forged transactions, per. Solana and Aptos lead with prototypes, while Ethereum and Bitcoin discuss but lag in implementation, per. NIST’s 2024 post-quantum standards (FIPS 203–205) guide these efforts, per. X sentiment praises Solana’s proactive approach, per @SolanaFndn posts.
Solana (SOL) trades at $184.50, with $8.6B DeFi TVL, poised for growth if quantum security boosts trust, per.

Diversify into BTC ($113,234) or ETH ($4,070) with stop-losses below $112,000 and $4,000, per TradingView. Follow @ProjectEleven on X for developments. Quantum resistance could drive $500B institutional inflows by 2030
