Gate News message, April 28 — Anza released a technical paper on protecting Solana from quantum computing threats, authored by Anza Chief Economist Max Resnick and Stanford applied cryptography Ph.D. Sam Kim. According to recent research by Google Quantum and Oratomic, the computational resources required to break 256-bit elliptic curve discrete logarithm problems (ECDLP-256) have decreased significantly, with quantum computers potentially posing a practical threat within five years at a 3-5% probability.
Solana’s current architecture relies on elliptic curve cryptography in four critical areas: account model (Ed25519 signatures), block propagation (Turbine/Rotor), consensus (Alpenglow BLS signatures), and signature verification in user-defined programs. All four components face vulnerability to quantum attacks.
To address the threat, Anza proposes a post-quantum migration strategy including adoption of NIST-standardized post-quantum signature schemes such as FALCON, implementation of address-preserving migration mechanisms based on zero-knowledge proofs of Ed25519 seeds, increased transaction sizes to accommodate larger signatures, and upgrades to the SVM, networking, and consensus layers.
