Sui Research Proposes Quantum-Safe Wallet Upgrade Method Potentially Benefiting EdDSA Chains Like Solana

Key Points

1. The upgrade uses zero-knowledge proofs to authorize secure key transitions, maintaining backward compatibility without requiring hard forks.

2. It is applicable to EdDSA-based blockchains like Sui, Solana, Near, and Cosmos, but not to Bitcoin or Ethereum, which use different cryptographic schemes.

3. Quantum computing poses a significant threat to current encryption methods, potentially breaking them, which makes this upgrade crucial for blockchain security.

4. Blockchain communities, especially Bitcoin's, are actively discussing quantum threats, including vulnerabilities of early wallets and potential freezing of compromised addresses.

5. The method is praised for being the first backward-compatible quantum-safe solution, ensuring broad applicability and security for EdDSA-based networks.
