Ethereum Proposes SPHINCS- for Cost-Effective Post-Quantum Security
Ethereum's SPHINCS- proposal offers a method to secure accounts against quantum threats for as low as $0.07 each. This initiative aims to mitigate risks associated with quantum computing while awaiting more comprehensive upgrades.

Ethereum is introducing the SPHINCS- proposal to enhance account security against quantum threats, allowing implementation at a cost of approximately $0.07 per account without necessitating a hard fork. Developed from the SPHINCS+ standard by the US National Institute of Standards and Technology, this approach reduces on-chain verification costs and serves as a temporary solution until future upgrades like leanSPHINCS are deployed.
Current estimates suggest that nearly 10% of Bitcoin's supply, or 1.92 million BTC, is vulnerable to quantum attacks, emphasizing the widespread urgency for quantum-resistant solutions. As quantum computing advances, Ethereum's core developers are targeting 2029 for comprehensive upgrades, but interim measures like SPHINCS- may help users enhance their account security sooner. The competitive landscape for post-quantum cryptography investment is also intensifying, with institutional players expressing concern over the risks of delays.
