Crypto ETF news: Ethereum Can Quantum-Proof Accounts for $0.07: Ethereum Researcher. This update explains what changed, why it matters for institutional adoption, market flows, and investor sentiment, and what the crypto market should watch next.
Institutional And ETF Update
Ethereum could begin adding post-quantum protections to accounts for as little as $0.07, without waiting for a hard fork, according to the Ethereum Foundation’s Kohaku project lead Nicolas Consigny.In a Saturday X post, Consigny shared a paper proposing a cheaper way for Ethereum users to protect their accounts against future quantum-computing threats. The approach adapts SPHINCS+, a post-quantum signature standard developed by the US National Institute of Standards and Technology, to work more efficiently on Ethereum. Dubbed “SPHINCS-,” the proposal aims to reduce onchain verification costs without requiring a protocol change or precompile. Consigny described SPHINCS- as a bridge toward a future post-quantum signature system dubbed “leanSPHINCS,” which aims to further reduce verification costs through aggregation.The proposal seeks to address the long-term risk of a quantum threat to Ethereum’s Elliptic Curve Digital Signature Algorithm with a cost-efficient solution that may be deployed before a dedicated hard fork is developed.Signature scheme SPHINCs variant security degradation and onchain verification costs.

He derived the private key from a public key paired to it, using a variant of Shor’s algorithm, a quantum computing technique that theoretically poses a threat to the type of cryptography used by Bitcoin.According to Glassnode, about 1.92 million Bitcoin, representing nearly 10% of the total supply, are considered “structurally unsafe” in a future quantum attack scenario. Another 4.12 million BTC, or 20.6% of the supply, are classified as “operationally unsafe” due to key or address management practices.Source: GlassnodeThe analytics company estimates that the remaining 69.8% of the supply, or 13.99 million Bitcoin, remains unexposed to a quantum computing threat, broadly in line with Ark Invest’s March estimate that 65% of the supply was safe.
