Key notes
- Project Eleven assessed the impacts of quantum computing on Solana’s infrastructure, validators, wallets, and cryptographic assumptions.
- It demonstrated that quantum-resistant transactions are already feasible on a large scale.
- Bitcoin advocates such as Michael Saylor also argue that Bitcoin can scale through upgrades and remain protected against quantum threats.
As the crypto community increasingly discusses the potential threats of quantum computing to blockchain technology, the Solana Foundation

took a first step to address these concerns.
The team is currently developing quantum-resistant blockchain security and has begun deploying post-quantum digital signatures on a Solana testnet.
Solana prepares for the post-quantum world
By testing post-quantum cryptography, Solana aims to evaluate protections against potential future threats to existing signature schemes.
With this, the Layer-1 blockchain joins the ranks of Ethereum

by first addressing the risks associated with quantum computing.
So far, the Solana blockchain has demonstrated strong performance in handling DDoS attacks this week.
The deployment to the Solana testnet shows early preparation as the industry prepares to bring long-term security to blockchain technology.
Quantum computers aren’t here yet, but the Solana Foundation is preparing for the possibility.
To this end, we consulted with Project Eleven to assess our quantum readiness.
We are pleased to announce a first step, the deployment of post-quantum signatures on a Solana testnet.

Earlier this year, in September 2025, Solana co-founder Anatoly Yakovenko warned that advances in quantum computing could eventually pose risks to Bitcoin.

existing cryptographic framework.
He estimates the likelihood of such a scenario occurring over the next five years is around 50%. Yakovenko stressed that the industry should take proactive measures to mitigate risks.
The Solana Foundation’s latest initiative comes as Project Eleven has conducted a comprehensive quantum risk assessment.
The Project Eleven review focuses on how future developments in quantum computing could affect Solana’s core infrastructure. It includes user wallets, validator security, and the network’s long-term cryptographic assumptions.
As part of this commitment, Project Eleven has also implemented a working post-quantum signature system on a Solana testnet.
It showed that quantum-resistant end-to-end transactions are already feasible and scalable with current technology.
Michael Saylor denies quantum threats to Bitcoin
Discussions about quantum threats to the Bitcoin blockchain have gained momentum again. Strategy chairman Michael Saylor denied any such risks.
Bitcoin’s Quantum Leap: Quantum computing won’t break Bitcoin, it will harden it. The network upgrades, active coins migrate, lost coins remain frozen. Security increases. Supply is decreasing. Bitcoin is getting stronger.
-Michael Saylor (@saylor) December 16, 2025
Last month in November, Adam Back, the creator of Hashcash and one of the key figures behind the design of Bitcoin’s proof of work, said that Bitcoin would not face significant quantum computing risk over the next 20 to 40 years.
He said post-quantum cryptographic methods already exist and could be integrated into Bitcoin long before quantum computers become powerful enough to pose a real threat.
Probably not for another 20-40 years, if that. And there are quantum secure signatures, standardized by NIST SLH-DSA last year. Bitcoin can add up over time as evaluation continues and be quantum ready, long before cryptographically relevant quantum computers arrive.
