Quantum-resistant crypto wallets now possible without address changes

Sui Research has developed a quantum-safe wallet upgrade using zero-knowledge proofs, allowing enhanced security without changing wallet addresses or triggering hard forks.

Sui Research revealed a way for blockchain wallets to upgrade for quantum safety without a hard fork or address changes.

Sui Research revealed a way for blockchain wallets to upgrade for quantum safety without a hard fork or address changes. The approach, based on EdDSA cryptography, allows compatible networks like Solana, Sui and Near to transition securely with minimal disruption.

Cryptographer Kostas Chalkias described the breakthrough as the first backward-compatible path to quantum safety for wallets. The upgrade uses zero-knowledge proofs to verify private key control without exposing data, keeping original public keys and supporting dormant accounts.

While praised as one of the most important cryptographic advancements in recent years, the upgrade method does not apply to Bitcoin or Ethereum. These networks use different signature methods, which may need bigger changes to stay secure as quantum tech evolves.

Although quantum computers are not yet capable of breaking blockchain encryption, researchers and developers are racing to prepare. The risk of millions of wallets becoming vulnerable has triggered serious debate in the crypto community.
