- Sui Research develops a quantum-safe fix, excludes Bitcoin and Ethereum.
- Upgrade path avoids hard forks, address changes, key updates.
- Bitcoin and Ethereum remain exposed to quantum threats.
Sui Research has developed a backwards-compatible quantum-safe upgrade for blockchain wallets, announced by cryptographer Kostas Chalkias, benefiting some chains but not Bitcoin or Ethereum.
Bitcoin and Ethereum remain vulnerable to future quantum threats, lacking backward-compatible cryptographic solutions unlike other blockchains potentially adopting Sui’s approach.

Sui Research Develops Quantum-Safe Technology
Sui Research has announced a groundbreaking quantum-safe cryptographic upgrade that is backwards-compatible. This solution ensures blockchain wallets can resist future quantum threats without requiring hard forks or changes in addresses and keys, a significant step forward in blockchain security.
The solution, however, notably excludes Bitcoin and Ethereum, leaving these major cryptocurrencies vulnerable to quantum threats. Sui Research led this initiative, with Kostas Chalkias, a well-known cryptographer, playing a pivotal role in the research. The breakthrough applies to blockchains like Solana, Near, and Cosmos.
“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.” – Kostas Chalkias, Cryptographer, Sui Research
Exclusion of Bitcoin and Ethereum: A Security Concern
The exclusion of Bitcoin and Ethereum from this upgrade path raises concerns over their future security. As these leading cryptocurrencies remain exposed to quantum threats, the development may impact community confidence and lead to shifts in the blockchain market landscape.
Although there’s no direct financial impact reported from Sui Research’s announcement, the research highlights a potential vulnerability in Bitcoin and Ethereum. Long-term implications could include increased pressure on these networks to develop or adopt quantum-resistant strategies.
Challenges and Future Directions
Past protocol upgrades demonstrate the challenges in implementing cryptographic changes through hard forks. Without backwards compatibility, this has previously led to network splits, as seen with Bitcoin Cash and Ethereum Classic. Industry leaders are now prioritizing quantum resistance in their development roadmaps.
Technological advancements in quantum computing continue to prompt discussions around blockchain security. As threats evolve, the need for quantum-safe measures in cryptocurrencies becomes urgent. Bold innovations like the ones explored by Sui Research present a framework for future solutions.
