Quantum-Resistant Cryptography: Solana and Aptos Lead Blockchain Security Transformation

In an era where quantum computer threats are no longer just a theory, the global blockchain ecosystem is undergoing a strategic shift toward long-term defense. Two major industry players—Solana and Aptos—have taken concrete steps to integrate post-quantum cryptography into their infrastructure. This move is not only about technological innovation but also about ensuring the sustainability of blockchain in the future when today’s protective technologies may no longer be sufficient.

Aptos Preparation: AIP-137 Proposal Paves the Way for New Signatures

The Aptos blockchain has taken the initiative by submitting a proposal called AIP-137, designed to launch the first post-quantum digital signature option on its network. This proposal awaits approval from token holders and will strengthen the use of SLH-DSA—a hash-based digital signature method that has become popular among researchers at the National Institute of Standards and Technology (NIST).

Aptos Labs’ decision to adopt stronger cryptography demonstrates a deep understanding of the evolution of security threats. The Ed25519 system, which currently manages transaction validation on Aptos, will remain the primary signature method. However, SLH-DSA will be available as an alternative account option, especially for users prioritizing post-quantum protection. The advantage of this approach is that it does not require a full network migration—users can choose their security level according to their needs.

Solana Foundation Partners with Project Eleven for Systemic Strengthening

Meanwhile, Solana has announced a strategic partnership with Project Eleven, a technology company specializing in post-quantum security for blockchain. Through an official announcement on X, the Solana Foundation emphasized that although quantum computers are not yet here, they are already preparing for that possibility.

This collaboration aims to evaluate Solana’s readiness to face potential quantum threats. As part of this effort, the Solana Foundation has designed a dedicated testnet using digital signatures developed to resist quantum attacks. The testnet is designed to ensure that quantum-resistant transactions can operate effectively at the network level without using technology that does not yet exist, without disrupting existing systems.

It is important to note that this initiative builds on Solana’s previous efforts to mitigate risks associated with quantum computing. In January of this year, the network successfully launched a preferred wallet feature known as Solana Winternitz Vault. This feature uses a hash-based signature system designed to protect user funds by creating a new cryptographic key for each transaction. Users have full freedom to decide whether to use it without changing the core protocol.

Leadership Perspective and Long-Term Vision

Matt Sorg, Vice President of Technology at Solana Foundation, expressed the organization’s commitment to maintaining blockchain security. According to him, their mission is to ensure Solana remains protected from now on, not waiting for quantum threats to materialize. Sorg also emphasized that the culture of innovation within the Solana ecosystem will continue to evolve through the launch of a second client and more advanced consensus mechanisms this year.

“Initiatives like Project Eleven are fundamental steps to strengthen network resilience and sustain Solana over time,” Sorg said, highlighting the importance of a proactive approach to future security threats.

Industry Momentum: Collective Response to Quantum Risks

Both initiatives reflect a growing industry awareness of the urgency of quantum-resistant cryptography. Industry analysts have noted that concerns about advances in quantum computing are increasing within the crypto sector. There is a consensus that progress in quantum technology could threaten the protection methods used by blockchains to secure transactions and validators.

With Project Eleven and Aptos leading this transformation, the global blockchain is positioning itself for a safer future. This collaborative and decentralized effort shows that the blockchain community is not only reacting to threats but also proactively building resilient infrastructure for the next generation of users.
