Is Solana Quantum Safe in 2026?

SOL's High-Speed Chain vs Quantum Computing

⚠️ Quick Verdict: NOT Quantum Safe

  • ❌ Uses Ed25519 signatures - broken by Shor's algorithm
  • ❌ All wallets and programs use quantum-vulnerable keys
  • ❌ Validator keys exposed on-chain
  • ⚠️ High throughput = more exposed public keys

Solana's Quantum Vulnerabilities

Solana uses Ed25519 (EdDSA) exclusively for all signatures:

  • Wallet transaction signatures
  • Program (smart contract) authority
  • Validator block signatures
  • Vote transactions

All of these are vulnerable to Shor's algorithm.

High Throughput = High Exposure

Solana's 65,000+ TPS means millions of signatures expose public keys daily. This creates a massive attack surface for future quantum computers.
