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, a cryptographer from Greece wrote: 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 told Cointelegraph, a research at Unstoppable Wallet that this paper “is one of the most important cryptographic breakthroughs we’ve seen in recent years.” It was explained to him that he is able. quantum-safe wallet upgrades Without requiring any changes in addresses, signatures or other alterations 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, also known as EtherETHEthereum Classic (ETC).

Quantum threat is looming
Chalkias doubted “we’re anywhere near quantum supremacy that can break cryptography soon,” Experts are aware of the real threat.
Developers have a growing need for solutions to the problem of quantum computers being able to crack cryptography used in blockchains.
Bitcoin has also seen an increase in heated debates within its community. During an April interview with Cointelegraph Adam Back, cited in Satoshi’s Bitcoin whitepaper, as a cypherpunk, claimed that the pressure of quantum computing may reveal 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.”

The new equation that this invention introduces
Many solutions are being proposed to counteract the quantum threat. These include changing to keys based post-quantum cryptography, and overhauling the software on which the network runs. With the new solution it is possible to upgrade a wallet without having to change addresses or require a fork.
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 from 3MI Labs in the cryptography department, said to Cointelegraph, that this method is effective. “allows to hide certain data that a quantum adversary would need for attacking the scheme.” Then 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. The old EdDSA key could still be used, and there would not need to be any new IDs for accounts.
Dormant accounts will be covered. 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 added.
