Ethereum Foundation’s privacy initiative Kohaku declares that post‑quantum account protection can be rolled out today at a cost of $0.07 per account, eliminating the need for a hard fork.
Implementation Details
The $0.07 figure represents the deployment expense for each Ethereum account when using the proposed solution. Initial security review was conducted with the auditing firm Fable, and additional audits are slated for the coming weeks. Kohaku’s lead, Nico, highlighted that the design includes formal verification to satisfy rigorous crypto standards.
Security Context and Future Plans
Quantum computers threaten the ECDSA signature scheme that currently secures Ethereum and Bitcoin accounts, prompting urgent calls for post‑quantum safeguards. Researchers are evaluating SPHINCS+ as a viable stateless signature method for the Ethereum Virtual Machine. As the crypto market watches, investors anticipate that early adoption of quantum‑resistant technology could influence Ethereum’s price stability and broader blockchain confidence.
