Ethereum can quantum-proof accounts for just 7 cents, says Kohaku lead

Ethereum Foundation researcher Nicolas Consigny proposed an interim post-quantum signature system that could protect Ethereum accounts for about 7 cents without requiring a hard fork.

The proposal, called SPHINCS-, aims to reduce the cost of post-quantum signature verification on Ethereum while the network works toward a longer-term solution. Currently, quantum computers could theoretically break Ethereum's existing elliptic curve cryptography, but practical quantum attacks remain years away. Consigny's approach uses hash-based signatures that are resistant to quantum attacks, and the estimated cost of 7 cents per transaction makes it economically viable for everyday use.

For cryptocurrency traders, this development is significant because it addresses a long-standing existential risk for blockchain networks. The ability to quantum-proof accounts cheaply could boost confidence in Ethereum's long-term security, potentially supporting its value proposition as a store of value and platform for decentralized applications. Traders can monitor Ethereum's price action and network upgrades on NowPrice's live crypto dashboard to stay informed.

Looking ahead, the Ethereum community will need to evaluate the SPHINCS- proposal and decide whether to implement it as a temporary measure. The broader crypto industry is also watching for advancements in quantum computing and how other networks like Bitcoin plan to address similar vulnerabilities. Any concrete steps toward quantum resistance could become a key narrative for Ethereum in the coming years.
