今日加密貨幣動態
====================================

想知道今天加密貨幣界發生了什麼事嗎？以下是影響比特幣價格、區塊鏈、去中心化金融（DeFi）、非同質化代幣（NFT）、Web3 及加密貨幣監管的最新消息。

以太坊的Fusaka分叉在最後測試網上首次亮相
——————————————————————-

以太坊的下一次重大升級Fusaka於周二在區塊鏈的最後測試網Hoodi上正式啟用，為定於12月3日的主網上線鋪平了道路，這次升級預計將為網絡帶來多項可擴展性和安全性改善。

Fusaka將添加多個以太坊改進提案（EIPs），例如EIP-7594的Peer Data Availability Sampling（PeerDAS），使驗證者能夠在第二層網絡上讀取較小的數據片段，而不是完整的數據塊，從而提高節點效率。

此外，EIP-7825和EIP-7935也包含在此次更新中，旨在提高燃料上限並改善效率，因為以太坊準備解鎖平行執行，即同時處理多個智能合約。其他EIPs則專注於改善零知識滾動。

這次升級旨在提高以太坊的可擴展性，這是以太坊聯合創始人Vitalik Buterin所稱的“區塊鏈三難題”的三個方面之一，另外兩個方面是去中心化和安全性。

Polymarket計劃於11月在美國重新啟動交易：報導
————————————————

預測平台Polymarket據報導計劃在幾周內在美國重新啟動交易服務。

根據周二彭博社的一份報導，Polymarket計劃在11月底之前向美國居民推出有限的交易服務，重點將放在體育博彩上。

此次重新啟動的報導是在美國商品期貨交易委員會（CFTC）表示已向Polymarket收購的加密衍生品交易所和清算所發出“不採取行動信函”後約兩個月發出的。這一舉措為該公司“在美國上線”鋪平了道路，根據首席執行官Shayne Coplan的說法。

9月份的報導顯示，如果Polymarket重新開放美國市場，該公司的估值可能高達100億美元。到6月，該預測平台的估值約為10億美元，這是在一輪2億美元的融資後的結果。

截至周二，Polymarket的網站顯示有等候名單，並表示將“很快對美國交易者開放”。Cointelegraph已聯繫該公司以獲取評論，但在發稿時尚未收到回覆。

Circle推出Arc測試網，BlackRock、Goldman Sachs、Visa參與
——————————————————————————

全球第二大穩定幣發行商Circle推出了Arc的公共測試網，這是一個旨在將全球金融基礎設施上鏈的開放式第一層區塊鏈網絡。

Circle稱這一推出為“互聯網的經濟運營系統”，超過100家主要公司參與其中，包括銀行、資本市場和金融科技公司，如BlackRock、Goldman Sachs、Visa、Mastercard和State Street。

Circle首席執行官Jeremy Allaire表示：“隨著Arc的公共測試網的推出，我們看到領先公司、協議和項目開始構建和測試，展現出驚人的早期動力。”他補充道：“這些公司合起來接觸到數十億用戶，處理、交換和保管數以百萬億計的資產和支付。”

Arc旨在提供可預測的美元計費、亞秒級的最終性和可選的隱私控制，並直接與Circle的USDC穩定幣和支付系統集成。它旨在支持廣泛的金融應用，從貸款和資本市場到全球支付和外匯（FX）。

此次測試網的推出吸引了包括Apollo、BNY Mellon、洲際交易所和德意志銀行在內的主要機構參與，以及全球支付公司如Mastercard、FIS、Paysafe和Nuvei。

這些最新的發展顯示，加密貨幣和區塊鏈技術的生態系統正在快速演變，尤其是以太坊的升級和Circle的Arc測試網，無疑將對未來的金融科技產生深遠影響。隨著越來越多的傳統金融機構進入這一領域，未來的競爭將更加激烈，這也意味著需要更高的創新和合規性來應對不斷變化的市場需求。這些動態不僅影響投資者的決策，也可能改變整個金融體系的運作模式，值得持續關注。
