比特幣「0 美元」引爆平倉潮!Paradex 定價異常釀災、緊急「回滾」引爭議

区块客

基於 Starknet 的永續合約交易所 Paradex,周一發生技術故障,比特幣在平台上竟短暫出現「0 美元」的極端報價,隨即爆發排山倒海的自動平倉潮,迫使官方罕見宣布將區塊鏈「回滾(Rollback)」,引發幣圈熱議。 社群平台上陸續有用戶回報,事故發生當下,Paradex 介面顯示比特幣價格瞬間歸零,隨後又迅速恢復正常。然而,就在價格回彈之前,數以千計的倉位已被系統判定爆倉並強制平掉。 一位用戶發文指出:「我一開始以為只是介面顯示錯誤(UI bug),直到我在電腦上看到比特幣跌到 0 美元後又馬上拉回來,才發現事情不對勁。現在已經出現成千上萬筆清算。這對 Paradex 來說絕不是好消息。」

🩸🚨Okay, when I posted the screenshot, I thought it was a UI bug.

Then I saw on the computer that the price came back after going to $0.

Now there are thousands of liquidations.

This doesn’t look good for @paradex ☠️ https://t.co/m4YbnfHkgN pic.twitter.com/QbKd3U432s

面對災難性故障,Paradex 官方稍後在 Discord 宣布,已鎖定問題源自於資料庫遷移期間的錯誤。為了修正錯誤,團隊決定採取極為罕見、且具爭議的應對手段 ——「回滾」。 Paradex 工程總監 Clement Ho 表示,系統將回溯到維護開始前的最後一個正確區塊(區塊高度 1604710)。這意味著故障發生期間的所有交易、清算甚至充提,都將被「撤銷」,試圖將交易所還原至故障前的狀態。 雖然這能拯救被無端清算的用戶,但同時也抹平了這段期間正常的獲利交易,引發正反兩極的評價。 在區塊鏈世界中,「重寫歷史」向來被視為極端且不得已的手段,因為這違背了去中心化系統最核心的信念 ── 交易一旦完成並獲得確認,就應該具備最終性(Finality),不可被任意推翻。 正因如此,當多數公鏈或協議遭遇重大故障時,慣常做法並非回溯已完成的交易,而是選擇暫停運行、或透過針對性修補來阻斷風險擴散,將傷害控制在最小範圍內。相較之下,動用「回滾」機制,等同於承認既有防護機制已徹底失靈。
