Sui Research's study marks a significant step in developing a cryptographic system capable of protecting blockchains from quantum computer threats. This system avoids complex changes such as hard forks or key replacements.
Breakthrough in Quantum Security for Blockchains
Cryptographer Kostas Chalkias stated in his post that the paper he prepared with Sui Research represents "a significant breakthrough" in protecting blockchains from quantum threats. According to him, this system applies to blockchains such as Sui, Solana, Near, and Cosmos but is not applicable to Ethereum and Bitcoin.
"As far as I know, this is the first backward-compatible upgrade path for wallets that provides quantum safety without the need for new hard forks or address changes," said Chalkias.
Quantum Threat to Blockchains
The existing threats posed by quantum computers are pushing blockchain developers to seek security solutions. Chalkias expressed doubt that "we're anywhere near quantum supremacy that can break cryptography soon," yet many experts are genuinely concerned about this threat. Discussions are even ongoing about whether quantum threats could impact the anonymity of Bitcoin's creator, Satoshi Nakamoto.
How the New Protection System Works
The proposed study focuses on using the Edwards-curve Digital Signature Algorithm (EdDSA) and zero-knowledge proofs to perform wallet upgrades without changing addresses or requiring hard forks. This allows for protection of both active and dormant accounts from quantum computer attacks. This approach offers the possibility of securing existing keys without the risk of exposure.
The new protection system developed by Sui Research represents an important step toward ensuring blockchain security against quantum technology threats. This research opens new horizons for further development of cryptographic systems capable of effectively countering future threats.
