Sui Research developed a cryptographic system that protects against threats posed by quantum computing without hard forks or address updates.
In a letter published on Monday, Kostas X post The recent research paper He co-authored with Sui Research “a major breakthrough in quantum transition of ‘some’ blockchains.” He said that the new method would be applied to Sui and Solana as well as Near, Cosmos, and other networks but not to Ethereum or 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.
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.” It was explained to him that the enables quantum-safe wallet upgrades It is possible to send a letter without changing the address, signing again or any other requirements. 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 (BTCBitcoin () and bitcoin Cash (BCHEther is a cryptocurrency (ETHEthereum Classic (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 breaking cryptography used to underpin blockchains, developers seek solutions urgently.
Bitcoin is also a subject of heated discussions within the community. In an April interview with Cointelegraph Adam Back, a cypherpunk who was cited as Satoshi in the Bitcoin White Paper, claimed that quantum computer pressure could reveal whether the blockchain’s pseudonymous creator is alive.
Back explained how quantum computing might make Satoshi’s Bitcoin vulnerable, causing him to have to change his address so as to not lose access to the 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.”

The new equation that this invention introduces
Many solutions are being proposed to counteract the threat of quantum computing. These include a change in keys from post-quantum to ones that use post-quantum cryptography, and an extensive rewrite of the code on which he network runs. 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. “
Chains can use this proof of zero knowledge as an authorisation to accept the new public key for a network. It would be possible to avoid new account IDs, resigning old transactions and a hard-fork by using the old EdDSA Public Key.
Dormant account coverage is important. If Bitcoin is used, then the account will be covered. EdDSA signatures From the beginning, Satoshi’s Bitcoin was not going to be frozen.
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 also added.
