Crypto Industry Prepares for Quantum Threats with New Signatures

As concerns about quantum computing's potential to break current cryptographic systems rise, blockchain platforms Solana and NEAR are advancing their preparations. Solana has begun testing the Falcon signature scheme, a quantum-resistant digital signature tool, which is designed to be activated without significant performance impact. NEAR's research team emphasizes the risk of ownership disputes arising from quantum-enabled attacks, planning to launch a testnet solution with FIPS-204 signatures by Q2 2026. The National Institute of Standards and Technology (NIST) has urged organizations to migrate to quantum-resistant algorithms to prevent future vulnerabilities. While quantum computers capable of breaking encryption do not yet exist, the industry is shifting from theoretical discussions to practical preparations, addressing risks like “harvest now, decrypt later.”

Key Points: • Solana and NEAR are testing quantum-resistant signature schemes to secure their networks. • NIST recommends immediate migration to post-quantum cryptographic standards to mitigate future risks. • Quantum attacks could lead to ownership disputes over stolen assets, complicating recovery efforts.
