Solana Runs Quantum-Resistant Signatures on Testnet, Taking a Major Step Toward Post-Quantum Security
Key Takeaways:
- Solana has successfully tested post-quantum digital signatures on a live testnet in collaboration with Project Eleven.
- The initiative includes a full quantum threat assessment covering wallets, validators, and core network cryptography.
- Results show that quantum-resistant transactions on Solana are already practical and scalable with today’s technology.
Solana has moved from theory to execution in addressing quantum risk. In a new collaboration, the network has tested quantum-resistant signatures on its testnet, signaling early but concrete progress toward long-term cryptographic security.

Solana Pushes Ahead on Post-Quantum Readiness
Solana Foundation has partnered with Project Eleven to prepare the Solana ecosystem for the future impact of quantum computing. The effort focuses on a problem many blockchains acknowledge but few have actively tested: how to secure digital assets once quantum machines become powerful enough to break today’s cryptography.
At the center of the collaboration is a working Solana testnet that uses post-quantum digital signatures. Unlike research papers or lab simulations, this prototype runs end to end, processing transactions secured by quantum-resistant primitives. The test shows that Solana can support stronger cryptography without breaking usability or network performance.
The work follows a broader industry concern that classical signature schemes, which secure most blockchains today, could eventually be compromised by quantum algorithms capable of deriving private keys from public data.
A Full Quantum Threat Assessment for the Network
Before deploying new cryptography, Project Eleven conducted a deep assessment of how quantum advances could affect Solana at every layer.
What the Risk Review Covered
The analysis examined several critical areas:
- User wallets and the long-term safety of public-key exposure
- Validator identity and the risk of signature forgery
- Core assumptions in Solana’s cryptographic design
- System-level threats, including long-range and delayed decryption attacks
One scenario highlighted by experts is often described as “harvest now, decrypt later.” In this model, attackers collect encrypted blockchain data today and wait until quantum hardware becomes capable of breaking it. For public blockchains with permanent data availability, this risk grows over time.
Project Eleven’s assessment did not just list threats. It outlined mitigation paths and migration options that Solana could adopt as quantum technology matures. This gives the ecosystem a practical roadmap rather than a vague warning.
Testnet Deployment Proves Feasibility at Scale
The greatest success in the partnership is that a live Solana test net has been implemented with the use of post-quantum signatures. The system accommodates real transaction flows that are secured by quantum-resistance cryptography as stated by Project Eleven.
This is important as post-quantum schemes are usually discouraged as being either too slow or too large to be run on high-performance blockchains. The testnet by Solana addresses that issue by demonstrating that more robust signatures do not have to obstruct high confirmation times and scale.
This makes Solana ahead of other major Layer-1 networks, in terms of practical experimentation. An example, Bitcoin and Ethereum, continue to use classical signature schemes and have not publicly shown post-quantum signatures production-style flows of transactions.

Project Eleven’s Role in Quantum Migration
Project Eleven operates at the intersection of advanced cryptography and real-world blockchain engineering. Beyond Solana, the company is developing post-quantum tooling, monitoring systems, and migration strategies for multiple digital asset platforms.
According to CEO Alex Pruden, Solana’s approach stands out because it did not wait for quantum computing to become an immediate crisis. Instead, the network invested early, asked difficult questions, and tested real solutions. The outcome shows that post-quantum security is not theoretical, it can be implemented with current technology.
