Ethereum Researcher Says Quantum-Proof Accounts Could Cost About 7 Cents
Ethereum’s Kohaku lead says a SPHINCS- proposal could make post-quantum signature verification cheap enough for account-level protection. The idea is presented as a lower-cost step while Ethereum works toward a longer-term quantum-resistance strategy.

Ethereum’s Kohaku lead says a SPHINCS- proposal could make post-quantum signature verification cheap enough for account-level protection. The idea is presented as a lower-cost step while Ethereum works toward a longer-term quantum-resistance strategy.
Why it matters
The work does not appear to be presented as Ethereum’s final answer to quantum risks. Instead, it is framed as an interim approach that could help accounts gain stronger protection while the ecosystem works toward a more comprehensive long-term solution.
An Ethereum researcher involved with Kohaku says Ethereum accounts could be made quantum-resistant for about 7 cents using a SPHINCS- proposal designed to lower post-quantum signature verification costs on the network.
The development matters because quantum resistance is a long-running security concern for public blockchains. If verification can be made inexpensive, Ethereum users and developers may have a more practical path to protecting accounts while broader protocol-level solutions continue to be explored.
The proposal focuses on SPHINCS-, a post-quantum signature approach, and its role in reducing the cost of verifying signatures on Ethereum. Lower verification costs are important because expensive cryptographic checks can limit whether a security upgrade is usable at scale.
The work does not appear to be presented as Ethereum’s final answer to quantum risks. Instead, it is framed as an interim approach that could help accounts gain stronger protection while the ecosystem works toward a more comprehensive long-term solution.
For now, the key takeaway is narrow but significant: Ethereum researchers are examining ways to make post-quantum account security cheaper and more practical, without treating the proposal as a complete replacement for future network-wide upgrades.
