Backwards-compatible quantum fix found, but not for Bitcoin and Ethereum
Sui Research’s new quantum-safe wallet upgrade method offers a hard fork-free solution for EdDSA-based blockchains, but does not apply to Bitcoin or Ethereum.
Sui Research has introduced a cryptographic framework that could offer protection against quantum computing threats without requiring hard forks, address changes or key updates.
Cryptographer Kostas Chalkias wrote in a Monday X post that the recent research paper he co-authored with Sui Research constitutes “a major breakthrough in quantum transition of ‘some’ blockchains.” He explained that while the new approach would apply to Sui, Solana, Near, Cosmos and other networks, it would not apply to Ethereum and Bitcoin.
“As far as I know, this is the first backward-compatible quantum-safe upgrade path for blockchain wallets to avoid future forks or freezing accounts,” Chalkias said.
