The work addresses a possible future threat to Bitcoin. A sufficiently powerful quantum computer could use a wallet’s exposed public key to work out its private key and steal the coins. StarkWare’s method adds a form of protection based on hashes, which are expected to withstand that attack. It fits within Bitcoin’s existing rules, so trying it did not require the network to approve an upgrade.
As such, the method is an emergency option for moving eligible coins if the quantum threat arrives before Bitcoin adopts a broader fix. Using it widely would be expensive at $320 of computing per transaction — and a lower bill could make the option more practical.

The $66 figure remains an estimate drawn from a test of the computation. The improved code has not been shown preparing another transaction mined on Bitcoin.
Applying the speedups displayed on the contest site to its listed $320 cost breakdown yields about $83, according to CoinDesk calculations. The site says later record-setting runs go beyond those measurements, without showing which results bring its transaction estimate to $66.
Meanwhile, the method also has limits beyond cost. These transactions have to be sent directly to a miner because they do not travel through the network in the usual way, and they do not protect coins whose public keys are already exposed, which is the group a quantum attacker would reach first.
. Your task is to write a brand-new article using the core information from the source while completely reimagining its structure, phrasing, and presentation. Guidelines for Content Creation Tone & Style: Use a neutral, professional, and informative tone. Ensure the language is clear, concise, and engaging for a broad audience. Avoid subjective opinions or commentary—stick strictly to the facts. Content Requirements: Do not copy sentences verbatim; instead, paraphrase, restructure, and enhance the information while keeping all details intact. Present a fresh perspective while preserving the factual accuracy of the original content. Use concise, well-organized sections to improve readability. Ensure all data, statistics, and sources remain accurate without distortion. Quote & Attribution Rules (Strictly Enforced): Direct quotes must remain unchanged—never reword or modify a quote. All direct quotes must be accurately attributed to their original speaker. Correct Example: “Innovation is the key to growth,” said John Doe, CEO of TechCorp. If an interviewee clarifies a misconception (e.g., Fonda distancing herself from “No pain, no gain”), retain their exact wording to ensure accuracy. If the original article attributes information to a source, ensure that attribution is retained. Original: According to a report by Bloomberg, the industry is expected to grow 20% by 2026. Correct Rewrite: Bloomberg reports that the industry is projected to expand by 20% by 2026. Never misattribute or create false attributions. Formatting & Structure (HTML Required): Write the article in valid HTML format to ensure proper webpage display. Use headings for major sections and subheadings for key points where applicable. Keep paragraphs short and scannable to enhance online readability. Include bullet points or numbered lists where useful for breaking down complex information. SEO & Readability Guidelines: Follow SEO best practices: Use descriptive, keyword-rich headings that naturally fit the topic. Incorporate primary and secondary keywords strategically without overstuffing. Ensure a clean, semantic HTML structure that improves search engine indexing. Where relevant, include: Meta descriptions summarizing the article in under 160 characters. Alt text for any referenced images. Internal and external links where applicable (only if relevant to the article’s content). Hyperlinks & Source Retention: Retain only links that serve a clear purpose, such as: Product links that are relevant to the article. Source links for studies, reports, or direct quotes. Remove all unnecessary links, including: Newsletter sign-up links “Related Articles,” “Read More,” or “Suggested Content” links Unrelated promotional or self-referential links Do not replace removed links with generic text. Example of correct link formatting in HTML:

Additional Considerations: The article must be completely original and uniquely worded—it should not resemble the source in structure or phrasing. Ensure the final output is engaging, logically structured, and free of errors. Do not fabricate facts, misinterpret data, or introduce speculation. Fact-check when necessary to ensure all referenced information is up to date. Instructions for Execution: Analyze the source content and identify its core information and key takeaways. Reimagine the structure while ensuring factual integrity and a fresh perspective. Write a fully original article that adheres to all tone, SEO, and formatting guidelines.
