Sui Research introduced a framework for cryptography that offers protection from quantum computing threats, without the need to change addresses or keys.
In a letter published on Monday, Kostas Chalkias explains that he is a cryptographer. post The recent research paper The book he wrote with Sui Research is a “a major breakthrough in quantum transition of ‘some’ blockchains.” He clarified that Ethereum and Bitcoin would still be subject to the old approach, which would only apply to Sui Solana Near 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,” Chalkias said.
Dan Dadybayo is a researcher with Unstoppable Wallet. He told Cointelegraph this was a paper that would be of interest to the public. “is one of the most important cryptographic breakthroughs we’ve seen in recent years.” He explains that it is possible quantum-safe wallet upgrades Without requiring any changes in addresses, signatures or other a hard fork.
Hard forks are permanent changes to the blockchain protocol. They’re not compatible with older software, so nodes that run the old version of the program can’t verify blocks.
If network administrators do not adopt hard forks fully, they can be controversial and lead to two different networks. Notable examples include Bitcoin (BTCThe Bitcoin Cash (BCHEther is a cryptocurrency (ETHEthereum Classic () is a cryptocurrency that was launched in 2009.ETC).

A looming threat to quantum technology
Chalkias doubted “we’re anywhere near quantum supremacy that can break cryptography soon,” Experts are aware of the real threat.
As quantum computing becomes more capable of destroying the cryptography underpinning blockchains, developers seek solutions urgently.
Bitcoin has also seen an increase in heated debates within its community. In an interview conducted by Cointelegraph in mid-April, Adam Back, the early cryptopunk cited in Satoshi’s Bitcoin whitepaper, said that quantum computing could reveal information. whether the blockchain’s pseudonymous creator is alive.
Back said that the quantum computer could render Satoshi’s Bitcoin vulnerable to theft, forcing Satoshi to transfer it to another address in order to keep his coins. Bitcoin users may also have to decide if they want to lock down addresses vulnerable to quantum attacks when these become feasible. Chalkias added:
“Once quantum computers arrive, millions of wallets, including Satoshi’s, could be drained instantly. If your public key is visible, it will eventually be cracked.”

This innovation has changed the equation
Many solutions are being proposed to counteract the quantum threat. These include changing the keys of existing wallets with new ones that use post-quantum cryptography, and overhauling the entire software platform on which it is built. The newly proposed solution would allow for quantum-safe upgrades to wallets without requiring any hard forks, address changes, or signature rework.
This breakthrough is centered on chains using the Edwards Curve Digital Signature Algorithm (EdDSA).
Dadybayo stated that “this is possible because EdDSA-based [Edwards-curve digital signature algorithm] chains like Sui, Solana and Near derive private keys deterministically from a seed which can be used in zero-knowledge proofs to authorize a secure transition, even for dormant accounts.” The zero-knowledge proof allows users to demonstrate that they are aware of the seeds from which the keys were derived, without having to reveal the key.
Tomer Ashur of 3MI Labs’ cryptography research department told Cointelegraph this is the right approach. “allows to hide certain data that a quantum adversary would need for attacking the scheme.” “He added”
“Rather than replacing EdDSA, what this approach does is to fortify the algorithm against quantum attacks. “
This zero-knowledge-proof can be accepted by the chain as authorization for a new post-quantum key to become the network key. It would be possible to avoid new account IDs, resigning old transactions and a hard-fork by using the old EdDSA Public Key.
Dormant accounts will be covered. If Bitcoin is used, then the account will be covered. EdDSA signatures There would not be heated debates about whether Satoshi Nakamoto’s Bitcoin will be frozen at some point in the future.
Robert Roose, founder of Cardano interoperability protocol Mynth, admitted that — if the paper is correct — this is a major development. “Caveat on the if,” He added.
