​加密貨幣的量子難題 (Crypto's Quantum Problem)

​Google 最新論文首次為破解 secp256k1(兩個網路共用的簽章曲線)的資源估算給出實際數字。我們將拆解:

• ​更新後的攻擊成本 論文提出的三種攻擊模型:on-spend、at-rest、on-setup

• ​為什麼 Bitcoin 與 Ethereum 的曝險方式截然不同。

• ​Bitcoin 的核心問題在於花費時的 mempool 時間窗口;Ethereum 則更偏結構性,橫跨帳戶、admin keys、staking,以及以 KZG 為基礎的 data availability。

​導讀人

​Ko-Wei Tseng (IOTA 亞洲生態系負責人) — Whitepaper Reading Club 元老級成員,從第一場就跟到現在。他同時是 NUS 量子物理博士,也曾參與《Mastering Monero》的中文翻譯。

​

​Session 形式

• ​開場 10 分鐘靜默閱讀

• ​討論優先,不設 panel

• ​歡迎帶問題來(技術深度沒問題)

• ​會後分享簡短筆記與重點整理

​

​XueDAO

​XueDAO 是台灣第一個由學生主導、專為學生開發者打造的社群。目標是成為學生的區塊鏈學習基地,讓世界看見 Taiwanese Students Can BUIDL。

​貢獻者團隊來自全球 12+ 所大學,長期舉辦共學日(co-learning day)、讀書會、hackathon 與產業講座,並在 ETH Taipei 期間籌辦 events。

​特別感謝 Fluidkey 亞太區負責人 Jennifer Hsu 帶來這場 session🙏

​

​📖 Whitepaper Reading Club（WPRC）

​一個聚集 1,000+ builders、engineers、researchers 的全球社群，橫跨 Singapore、Kuala Lumpur、San Francisco、Lagos、Bangkok、New York — 每月聚在一起，圓桌式硬啃最新的 blockchain 項目和研究論文（是真的一行一行一起讀 XD）！

​WPRC獨立於任何生態，會討論任何有意思的blockchain題目。三年來活動完全會員支持，主持了100個不同的閱讀會。

​我們把它從新加坡帶來台灣了。這次也特別邀請到 WPRC 的 host 親自飛來擔任 moderator 🔥

​Google new paper puts real numbers on resource estimate for breaking secp256k1 — the signature curve behind both networks. We will break down:

• ​The updated attack cost

• ​The paper’s three attack models — on-spend, at-rest, and on-setup

• ​Why Bitcoin and Ethereum are exposed in very different ways. Bitcoin’s key issue is the mempool window during spends; Ethereum’s is more structural, spanning accounts, admin keys, staking, and KZG-based data availability.
