Ethereum is developing quantum-resistant accounts with minimal costs - Cryptocurrency news today

Ethereum is actively developing technologies to ensure network security in the face of future quantum threats. The lead researcher of the Kohaku project introduced a method that allows for the creation of quantum-resistant accounts with minimal operational costs — about 7 cents per signature.

What are quantum-resistant signatures and why are they needed for Ethereum?

Quantum computers have the potential to break most modern cryptographic algorithms, including those used in blockchains. Ethereum, as one of the largest smart contract platforms, understands the risks of future attacks. Therefore, developers are seeking solutions that can preserve user security even in a post-quantum world.

One such approach is the use of the SPHINCS- algorithm, which is a post-quantum cryptographic protocol for creating digital signatures. SPHINCS- offers higher cryptographic resilience against quantum attacks but has been considered too costly for practical blockchain applications due to high gas costs.

Innovations of the Kohaku project

The lead researcher of Kohaku proposed an optimized implementation of the SPHINCS- algorithm for Ethereum. It significantly reduces the costs of signature verification in the network, bringing the cost down to 7 cents per transaction, which is a very competitive figure for post-quantum solutions.

This approach does not require an immediate overhaul of the entire infrastructure but allows for gradual integration of quantum-resistant signatures into existing accounts and smart contracts. As a result, Ethereum users will be able to protect their assets without substantial additional expenses.

Potential challenges and next steps

While the optimization of SPHINCS- greatly reduces costs, the algorithm still has a larger signature size and complexity compared to traditional methods. Ethereum developers continue working on long-term solutions that can fully integrate quantum resilience into the network without compromising speed and cost.

Implementing quantum-resistant technologies will be an important step in ensuring Ethereum’s resilience for years to come, especially considering the global trends in quantum computing development.
