萊特幣開發團隊宣布發布萊特幣核心版本 0.21.4，該版本引入了重要的安全更新和功能改進。

The Litecoin development team announced the release of Litecoin Core version 0.21.4, which includes critical security updates and functional enhancements. This release aims to strengthen the Litecoin network and address several critical issues.

萊特幣開發團隊宣布發布萊特幣核心版本0.21.4，其中包括關鍵的安全更新和功能增強。此版本旨在加強萊特幣網絡並解決幾個關鍵問題。

Among the vulnerabilities fixed is CVE-2024-40202, which could allow remote attackers to carry out a DoS attack by inserting uncommitted transactions into the blocktxn message. This would trigger assertion errors and lead to the node exiting. The patch included in this release verifies that all transactions in the message correspond to the Merkle root of the block, ensuring transaction validity.

已修復的漏洞包括 CVE-2024-40202，該漏洞可能允許遠端攻擊者透過將未提交的交易插入到 blocktxn 訊息中來執行 DoS 攻擊。這將觸發斷言錯誤並導致節點退出。此版本中包含的補丁驗證訊息中的所有交易是否對應於區塊的 Merkle 根，從而確保交易的有效性。

Moreover, the update addresses a problem where a peer could delay the propagation of blocks by sending modified blocks, which could erase the download state of other peers and hinder the propagation process in the network. This improvement, backported from Bitcoin Core (dbfc748), reduces block propagation latency to enhance network throughput.

此外，該更新還解決了一個問題：對等點可能會透過發送修改後的區塊來延遲區塊的傳播，這可能會擦除其他對等點的下載狀態並阻礙網路中的傳播過程。這項改進是從 Bitcoin Core (dbfc748) 向後移植的，可減少區塊傳播延遲，從而提高網路吞吐量。

This version also includes a fix for a vulnerability in the miniupnp dependency, where a local attacker could cause an infinite loop and out-of-memory (oom) errors. The issue addressed in this release minimizes the occurrence of network disruptions due to memory depletion.

此版本還修復了 miniupnp 依賴項中的漏洞，本地攻擊者可能會在該漏洞中導致無限循環和記憶體不足 (oom) 錯誤。此版本中解決的問題最大限度地減少了由於記憶體耗盡而導致的網路中斷的發生。

Additionally, Litecoin Core v0.21.4 updates the -peerblockfilters and -blockfilterindex options to default to "off" when pruning is enabled. This change, along with other test-related improvements, enhances compatibility and reliability, particularly for pruned nodes.

此外，Litecoin Core v0.21.4 將 -peerblockfilters 和 -blockfilterindex 選項更新為啟用修剪時預設為「關閉」。這項變更以及其他與測試相關的改進增強了相容性和可靠性，特別是對於修剪的節點。

The Litecoin Core v0.21.4 release was made in collaboration with several authors and contributors, including Bitcoin Core developers David Burkett, Hector Chu, and Loshan. Users can download the new version of Litecoin here and are encouraged to report any bugs via the issue tracker on the Litecoin GitHub page.

Litecoin Core v0.21.4 版本是與多位作者和貢獻者合作發布的，其中包括 Bitcoin Core 開發人員 David Burkett、Hector Chu 和 Loshan。用戶可以在此處下載萊特幣的新版本，並鼓勵用戶透過萊特幣 GitHub 頁面上的問題追蹤器報告任何錯誤。

This security-focused release coincides with increasing prospects for Litecoin's institutional adoption. Canary Capital recently filed the first application for a Litecoin-based ETF with the U.S. Securities and Exchange Commission (SEC), paving the way for institutional investors to access Litecoin.

此次以安全為重點的發布恰逢萊特幣的機構採用前景日益樂觀。 Canary Capital 最近向美國證券交易委員會 (SEC) 提交了第一份基於萊特幣的 ETF 申請，為機構投資者投資萊特幣鋪平了道路。

The S-1 filing, made public on Oct. 15, marks a crucial first step, with the firm also needing to submit a 19b-4 form to gain the exchange's approval. The proposed ETF will hold Litecoin and calculate its net asset value daily.

10 月 15 日公開的 S-1 申請標誌著關鍵的第一步，該公司還需要提交 19b-4 表格以獲得交易所的批准。擬議的 ETF 將持有萊特幣並每日計算其資產淨值。

If approved, the spot LTC ETF would open the door for the approval of other cryptocurrency ETFs, with XRP being another candidate once the lawsuit between Ripple and the SEC is resolved.

如果獲得批准，現貨 LTC ETF 將為其他加密貨幣 ETF 的批准打開大門，一旦 Ripple 和 SEC 之間的訴訟得到解決，XRP 將成為另一個候選人。

Meanwhile, as these developments unfold, long-term investors continue to show interest in Litecoin. As reported previously by Crypto News Flash, Litecoin recently surpassed Ethereum in the longest average holding period, indicating that the currency continues to capture the attention of HODLers. At the time of writing, LTC is trading at $73.16, up 3.47% in the past day and 4.28% over the past week. It's worth noting that the coin has declined 42% from its all-time high of $412 registered three years ago.

同時，隨著這些事態的發展，長期投資者繼續對萊特幣表現出興趣。正如 Crypto News Flash 之前報導的那樣，萊特幣最近在最長平均持有期限上超過了以太坊，這表明該貨幣繼續吸引了 HODLers 的關注。截至撰寫本文時，LTC 的交易價格為 73.16 美元，過去一天上漲 3.47%，過去一週上漲 4.28%。值得注意的是，該代幣的價格較三年前創下的 412 美元歷史高點下跌了 42%。
