Solana Begins Quantum Proofing Update as Blockchain Industry Strengthens Security Measures

Jakarta, Pintu News – The Solana Foundation has taken a concrete step towards quantum-resistant blockchain security, by implementing post-quantum digital signatures on the Solana (SOL) testnet.

The move comes amid growing concerns that the threat of quantum computing may come sooner than previously thought.

Solana Begins Quantum Resistant Update

The Solana blockchain is now the latest addition to the list of networks wary of quantum computing threats. Following Ethereum (ETH) and Cardano (ADA), Solana has also started implementing security measures, by placing post-quantum signatures on testnets.

“Quantum computers are not here yet, but the Solana Foundation is preparing for the possibility. To that end, we have consulted with Project Eleven to assess our readiness for quantum. We are pleased to announce the first step, which is the placement of post-quantum signatures on the Solana testnet,” the Solana Foundation wrote in a post.

The move follows a comprehensive quantum risk assessment conducted by Project Eleven, a company specializing in post-quantum cryptography and migration strategies for digital assets.

The assessment examines how future quantum advances may affect Solana’s core infrastructure, validator security, user wallets, and long-term cryptographic assumptions.

The Solana Ecosystem is Always Moving Forward

As part of the collaboration, Project Eleven also deployed a working post-quantum signature system on the Solana testnet. This demonstrates that end-to-end quantum-resistant transactions are already practical and scalable using existing technologies.

The results of this assessment challenge the long-held assumption that quantum-safe blockchain systems are still a theoretical concern far in the future.

“Our responsibility is to make sure Solana stays safe, not just today, but decades into the future,” reads a quote in the official blog, which quotes Matt Sorg, VP of Technology at the Solana Foundation.

Sorg emphasized that the Solana ecosystem’s culture of always moving forward will continue with the launch of a second client and advanced consensus mechanism this year.

Efforts such as Project Eleven reflect concrete first steps to strengthen the network and stay at the forefront, ensuring Solana’s long-term resilience.

Project Eleven CEO Alex Pruden called Solana’s decision an example of proactive risk management rather than reactive security planning.

“Solana didn’t wait for quantum computers to become a big deal,” says Pruden. “They invested early, asked the hard questions, and took steps that can be taken today. The results show that post-quantum security at Solana is feasible with today’s technology.”

How Close is the Quantum Threat?

This announcement comes amid a growing debate over how closely quantum computing threatens the classical cryptographic systems used by blockchains like Bitcoin (BTC) and Ethereum.

Recent research suggests that the timeline for quantum threats may be getting closer, with estimates placing significant quantum risks within the next few years rather than decades.

Industry views remain divided. Cardano founder Charles Hoskinson has previously argued that quantum risks are exaggerated. The crypto executive suggested that a meaningful threat would only emerge after the achievement of military benchmarks, which is likely to happen in the 2030s.

He also warned that quantum-resistant cryptography can significantly increase computational costs and reduce performance.

Other networks are taking a more urgent stance. Ethereum has publicly prioritized quantum security as part of its long-term roadmap. Founder Vitalik Buterin warned that both Ethereum and Bitcoin could face cryptographic threats before the end of the decade if preparations are delayed.

Solana aside, this collaboration highlights a broader shift in the industry towards quantum-safe infrastructure. Experts are increasingly warning that blockchains that rely solely on classic signature schemes could eventually face risks, including:

• Stolen funds
• Falsified validator identity
• Cryptographic failures at deeper system levels

Project Eleven stated that it will continue to work closely with Solana and other ecosystem stakeholders. This stance was taken while the network evaluated:

• Migration path
• Emerging standards, and
• Post-quantum primitive adoption.

The deployment of the Solana testnet shows that the technical barriers to quantum resilience are beginning to be overcome. This is despite the fact that large-scale quantum computers capable of breaking blockchain cryptography do not yet exist.

Whether quantum threats emerge in two years or ten, the race to protect future blockchain security is clearly on, and Solana has positioned itself among the early movers.
