1 月 14 日晚間，一筆交易金額高達(dá) 256 億 XRP，價(jià)值約 150 億美元，引發(fā)了加密貨幣行業(yè)的擔(dān)憂。

這筆交易占 XRP 流通總量（約 542.6 億）的近一半。

據(jù)稱(chēng)，這筆轉(zhuǎn)賬來(lái)自身份不明的錢(qián)包，并被發(fā)送到加密貨幣交易所 Bitfinex。

256億XRP被轉(zhuǎn)移是真的嗎？

Bitfinex 首席技術(shù)官 (CTO) Paolo Ardoino 表示，更多分析表明，這是一次濫用 XRP Ledger 的“部分支付”功能的不成功的嘗試。

這一現(xiàn)象的發(fā)現(xiàn)證實(shí)了這一點(diǎn)。

著名的區(qū)塊鏈監(jiān)控工具 Whale Alert 是第一個(gè)讓這個(gè)問(wèn)題引起公眾注意的工具。

他們報(bào)道了X上發(fā)生的巨額交易。第一篇報(bào)道引起了市場(chǎng)的轟動(dòng)，人們擔(dān)心XRP賬本可能存在安全漏洞，這可能會(huì)對(duì)價(jià)格產(chǎn)生重大影響，但隨后被撤回市場(chǎng)上的 XRP。

鯨魚(yú)警報(bào)在承認(rèn)其報(bào)道不準(zhǔn)確后發(fā)表了澄清。

聲明稱(chēng)，“正確讀取 Ripple 節(jié)點(diǎn)響應(yīng)存在問(wèn)題，導(dǎo)致出現(xiàn)了一些錯(cuò)誤的帖子。”

“我們已經(jīng)解決了這個(gè)問(wèn)題。”

Tether 首席執(zhí)行官 Paolo Ardoino 提供了有關(guān)該問(wèn)題的進(jìn)一步信息。

他表示，“有人試圖通過(guò)‘部分支付漏洞’攻擊 Bitfinex?！庇捎?Bitfinex 以適當(dāng)?shù)姆绞教幚怼癲elivered_amount”數(shù)據(jù)字段，因此攻擊沒(méi)有成功。

此外，Ardoino 還關(guān)注了 xrpl.org 上的一篇文章，該文章提供了部分付款的全面解釋。

由于 XRP 賬本的這一功能，發(fā)送者能夠激活“部分付款”標(biāo)志，這會(huì)導(dǎo)致交付的金額低于“金額”字段中指定的金額。

利用此功能來(lái)欺騙網(wǎng)??關(guān)和交換的能力是使此漏洞成為可能的攻擊。

平臺(tái)應(yīng)使用“delivered_amount”元數(shù)據(jù)信息（與“金額”字段相反）來(lái)識(shí)別已傳輸?shù)膶?shí)際金額。

這是避免利用該類(lèi)別的最重要組成部分。

Only sixteen XRP were transmitted by the attacker in this specific instance, which is a striking contrast to the 25.6 billion XRP that was published. Due to the manner in which the Whale alarm systems process and report transactions, this rather little transaction resulted in an alarm being sent to the on-chain monitoring system.

Other exchanges were also attempted by the attacker.

In addition, the data from the blockchain showed that other big bitcoin exchanges had also attempted to engage in similar activities but were unsuccessful. The cryptocurrency exchange Binance was subjected to an attempt to transfer 58.9 billion XRP, while Bitstamp was the target of a transfer of 26,200,000 XRP. These transactions, including the one that was directed at Bitfinex, were a part of the exploiter's plan, and they did not result in the transfer of substantial amounts of bitcoin.

At the time of this publication, the market price of XRP shown resistance in the face of these episodes, successfully maintaining its stability at $0.58. Despite this, the bears of XRP shown their perseverance once again with the weekly close that occurred yesterday. At $0.59, the price reached a closing point that was lower than the crucial barrier representing the 0.5 Fibonacci retracement level. Nevertheless, the bulls were successful in defending the exponential moving average (EMA) that is considered to be 200 days.
