Sui research has introduced a cryptographic framework that can offer protection against quantum computing threats without requiring hard forks, address changes or important updates.
Cryptographer Kostas Chalkias wrote in a post on Monday X that the recent research paper that he was co-author of Sui-Research ‘a big breakthrough in the quantum transition of’ some ‘block chains’. He explained that although the new approach applies to sui, solana, near, cosmos and other networks, this would not apply to Ethereum and Bitcoin.
“As far as I know, this is the first backward compatible quantum-safe upgrade path for blockchain portfolios to prevent future forks or freezing accounts,” said Chalkias.
Dan Dadybayo, a researcher at unstoppable wallet, said Cointelegraph that this article is “one of the most important cryptographic breakthroughs that we have seen in recent years.” He explained that quantum-proof wallet upgrades makes possible without changes in addresses, sign up or require a hard fork.
A hard fork is a permanent change in the protocol of a blockchain that is not backward compatible, which means that nodes that run the old software, blocks that have been made under the new rules cannot validate.
Hard forks have the potential to be controversial and result in two separate networks if they are not fully taken over by network managers. Remarkable examples are Bitcoin (BTC) and Bitcoin Cash (BCH), as well as Ether (ETH) and Ethereum Classic (etc.).

The threatening quantum threat
While Chalkias said he has doubts: “We are everywhere near Quantum Supremacy who can break cryptography soon,” the threat is recognized by many experts.
As quantum computers are increasingly able to break the cryptography that supports block chains, developers look for solutions with growing urgency.
In the case of Bitcoin, there are also increasingly heated community discussions. During an interview in mid -April with Cointelegraph, early Cypherpunk Adam suggested back by Satoshi Nakamoto in Bitcoin’s white paper, which can reveal the pressure of the quantum computing or the pseudonym of the blockchain lives.
Back explained that Quantum Computing could make the Bitcoin of Satoshi Nakamoto vulnerable to be stolen, so that he forced it to move it to a new address to prevent him from losing access to his coins. The Bitcoin community can also be forced to decide whether they freeze addresses that are vulnerable to a quantum computer attack when those attacks become practical. Chalkias Added:
“As soon as quantum computers arrive, millions of portfolios, including Satoshis, can be removed immediately. If your public key is visible, it will eventually burst.”

How this innovation changes the comparison
Most solutions for the threat of the quantum computing include changing keys for newly based on cryptography after the quantum and a deep redevelopment of the software on which it is based on. Instead, it would be possible with the newly proposed solution to perform quantum-proof wallet upgrades without changing addresses, signing or requiring a hard fork.
The breakthrough focuses on chains that use the Edwards curve digital signature algorithm or eddsa.
Dadybayo said that “This is possible because it is based on Eddsa [Edwards-curve digital signature algorithm] Necklaces such as sui, solana and almost distracting private keys that distract deterministically to a seed that can be used in zero knowledge tickets to authorize a safe transition, even for sleeping accounts. “Zero-knowledge certificates enable users to prove that they know the seed from which their keys are derived without revealing the key.
Tomer Ashur, scientific director at Cryptography 3MI Labs, told Cointelegraph that this approach “makes it possible to hide certain data that a quantum opponent would need to attack the schedule.” He added:
“Instead of replacing Eddsa, this approach is to strengthen the algorithm against quantum attacks.”
The chain can accept this zero knowledge-resistant as an authorization to accept a public key after quantum as the new key to the network. This would prevent the need for new account IDs (the old Eddsa-public key would still be used), re-signing old transactions or a hard fork.
The most important thing is that sleeping accounts are treated. In other words, if Bitcoin Eddsa signatures were to use from the start, there would be no heated discussions about whether the Bitcoin of Satoshi Nakamoto would be frozen in the future.
Robert Roose, founder of Cardano Interoperability Protocol Myth, admitted that – if the newspaper is correct – this is an important development. “Reserve on the IF,” he added.
