Ethereum Foundation’s Kohaku proposes cheaper post-quantum account protection on Ethereum
The opt-in proposal uses SPHINCS+ to lower post-quantum signature verification costs to about $0.07 per account as a near-term step while Ethereum works on longer-term quantum-risk defenses.

Summary
Ethereum Foundation researcher Kohaku has proposed an opt-in post-quantum account protection approach for Ethereum that would use SPHINCS+ to reduce post-quantum signature verification costs to about $0.07. The proposal is presented as a near-term, lower-cost measure rather than a final solution, as Ethereum continues pursuing longer-horizon protections against potential future quantum computing threats.
Terms & Concepts
- SPHINCS+: A post-quantum digital signature scheme.
- post-quantum account protection: Security measures for accounts designed to resist future quantum-computing attacks.
- opt-in: Optional participation chosen by users.
