The Solana Foundation has taken a concrete step towards quantum-resistant blockchain security by implementing post-quantum digital signatures on the Solana testnet.
The move comes amid growing concern that quantum computing threats may arrive faster than expected.

Solana begins quantum resistance upgrade with implementation of post-quantum test network
The Solana blockchain is the latest addition to the list of networks that remain wary of the threat of quantum computing. After Ethereum and Cardano, Solana is also introducing secure measures, publishing post-quantum signatures in the test network.
“Quantum computers have not arrived yet, but the Solana Foundation is preparing for this possibility. For this purpose, I consulted Project Eleven to assess quantum readiness. We are pleased to announce the first step, which is the publication of post-quantum signatures in the Solana testnet.” I wrote Fondazione Solana in publication.
The move comes after a comprehensive quantum risk assessment conducted by Project Eleven, a company specializing in post-quantum cryptography and migration strategies for digital assets.
The assessment examined how future quantum developments could impact Solana’s underlying infrastructure, validator security, user wallets, and long-term cryptographic assumptions.
As part of the interaction, Project Eleven also implemented a post-quantum signature system running on the Solana testnet. It shows that end-to-end quantum-resistant transactions are practical and scalable with current technology.
The results challenge the long-standing assumption that quantum-secure blockchain systems remain a distant theoretical concern.

“Our responsibility is to ensure that Solana remains safe not only today, but for decades to come.” As stated Excerpt in the official blog, quoted by Matt Sorg, Vice President of Technology at Solana Foundation.
Sorg noted that the shipping culture in the Solana ecosystem continues with the release of a second client and an evolving consensus mechanism this year.
Efforts like Project Eleven reflect the first concrete steps to strengthen the network and stay ahead of the curve. This ensures the long-term resistance of Solana.
Project Eleven CEO Alex Broden framed the Solana decision as an example of proactive risk management rather than reactive security planning.
“Solana didn’t expect quantum computers to become a big problem,” Broden said. “They invested first, asked the hard questions, and took practical steps today. The results show that post-quantum security in Solana is viable with current technology.”

How close is the quantum threat? Crypto executives disagree as times tighten
The announcement comes amid growing controversy over… How close is quantum computing? Classic cryptosystems used by blockchains like Bitcoin and Ethereum.
Recent research suggests that the schedule may be in congestion, with estimates that pose significant quantitative risks During the coming years Instead of decades.
Industry views remain divided. Cardano founder Charles Hoskinson had… Previously argued that quantum risks are exaggerated. The cryptocurrency executive suggests that significant threats will emerge only when military benchmarks are achieved, perhaps in the 2030s.
He also warned that quantum-resistant cryptography could significantly increase computing costs and reduce performance.
Other networks take a more urgent stance. He gave the Ethereum He publicly prioritized quantum security as part of his long-term roadmap. Co-founder Vitalik Buterin warns that Ethereum and Bitcoin could face crypto threats before the end of the decade if preparations are delayed.

Beyond Solana, the collaboration highlights a broader shift in the industry toward secure quantum infrastructure. Experts are increasingly warning that blockchains that rely solely on classic signature systems may eventually face risks, including:
- Stolen money
- Identity of fake auditors
- Deeper system-level encryption flaws
Project Eleven said it will continue to work with Solana and other players in the ecosystem. This situation comes as the networks assess:
- Migration routes
- Emerging standards, and
- Embrace post-quantum primitives.
The implementation of the Solana testnet indicates that the technical barriers to quantum resistance are already beginning to fall. This is despite the fact that large-scale quantum computers capable of breaking blockchain encryption have not yet appeared.
Whether quantum threats emerge in two years or ten years, the race to future-proof blockchain security is still on, and Solana has positioned itself among the first movers.
