Ethereum may be able to protect user accounts against future quantum computer attacks for as little as seven cents per transaction, according to the lead developer of Ethereum's Kohaku project, as reported by Cryptonews.net.
The proposal addresses one of the most discussed long-term threats to blockchain technology: the possibility that quantum computers, once powerful enough, could break the cryptographic protections that currently secure digital wallets. Today's encryption relies on mathematical problems that are practically unsolvable for classical computers — but advanced quantum machines could, in theory, crack them.
According to Cryptonews.net, the Kohaku lead's claim suggests that upgrading accounts to quantum-resistant cryptography would not require a costly or disruptive overhaul. At seven cents per transaction, the proposed solution would make quantum-proofing accessible to ordinary users rather than limiting protection to high-value institutional accounts.
Ethereum has been undergoing a series of technical upgrades aimed at improving scalability and security, and quantum resistance has become an increasingly active area of research across the broader cryptocurrency industry.
No timeline for implementation or specific technical mechanism was detailed in the available source material, and the claim remains a proposal rather than a finalized protocol change.
If the seven-cent figure holds up under scrutiny, it could signal that the blockchain industry is closer than many expected to a practical, affordable defense against one of the most significant emerging threats to digital asset security.
