比特幣核心的磁盤填充錯誤：終於被壓扁了嗎？

比特幣核心開發人員似乎終於消滅了自2020年以來一直困擾著完整節點操作員的討厭磁盤填充攻擊。

Bitcoin Core developers have been battling a persistent disk fill attack since 2020. The latest news suggests they may have finally squashed it! This blog post dives into the details of this long-standing issue and the potential fix.

自2020年以來，比特幣核心開發人員一直在與持續的磁盤填充攻擊作鬥爭。最新消息表明他們可能最終將其壓制！這篇博客文章介紹了這個長期存在的問題的細節和潛在的解決方案。

The Disk Fill Attack: A Nuisance for Full Nodes

磁盤填充攻擊：完整節點的滋擾

The disk fill attack is a real headache for those operating full Bitcoin nodes. Attackers exploit commands like LogPrintf to flood the node's hard drive with excessive, pointless data. For older nodes with spinning disks, this can be crippling, filling up their storage with garbage.

對於那些操作完整的比特幣節點的人來說，磁盤填充攻擊是一個真正的頭痛。攻擊者利用諸如logprintf之類的命令以過多，毫無意義的數據充斥節點的硬盤驅動器。對於帶有旋轉磁盤的較舊節點，這可能會癱瘓，並用垃圾裝滿他們的存儲空間。

Even flash storage isn't immune. The constant writing can degrade the disk and even cause the entire machine to crash. It's like being forced to write the same sentence over and over until your hand cramps up and falls off.

甚至閃存存儲也無法免疫。恆定的寫作會降解磁盤，甚至導致整個機器崩潰。這就像被迫一遍又一遍地寫下相同的句子，直到您的手痙攣並掉下來。

The Extermination Attempt: A Five-Year Saga

滅絕嘗試：一個五年的傳奇

Bitcoin Core Pull Request (PR) 32604, a revival of several earlier attempts, represents the culmination of five years of work. Senior Bitcoin Core developer Gloria Zhao merged bug patch 2d59977 into the master branch. The commit passed all checks with no negative acknowledgements from other developers.

比特幣核心拉的請求（PR）32604，復興了幾次嘗試，代表了五年工作的高潮。高級比特幣核心開發人員Gloria Zhao將Bug Patch 2D59977合併到主分支。該提交通過了所有支票，沒有其他開發人員的負面感謝。

Bitcoin Core Version 30: Expanding OP_RETURN

比特幣核心版本30：擴展OP_Return

In other news, Bitcoin Core's upcoming version 30 (slated for October 2025) will dramatically raise the OP_RETURN data limit—from 80 bytes to nearly 4 MB. This change permits developers to put more rich metadata on-chain. While proponents argue this enables more complex, data-driven Bitcoin applications, critics express concern that it could bloat the blockchain and negatively impact decentralization. It's a bit of a trade-off, but could open new doors for Bitcoin use.

在其他新聞中，比特幣Core即將推出的版本30（定於2025年10月）將大大提高OP_Return數據限制，從80個字節到近4 MB。這種變化使開發人員可以將更豐富的元數據放在鏈上。儘管支持者認為這可以使更複雜的數據驅動的比特幣應用程序，但批評家表示擔心它可能會膨脹區塊鏈並對分散性產生負面影響。這是一個權衡，但可以為使用比特幣打開新的門。

The Future: Hopeful, but Vigilant

未來：充滿希望的，但保持警惕

The hope is that with the next Bitcoin Core release, this patch will spread across the network and finally put an end to the disk fill attack. As a voluntary software package, full node operators need to manually upgrade to benefit from the fix.

希望是，隨著下一個比特幣核心版本，該補丁將遍布整個網絡，並最終結束磁盤填充攻擊。作為一個自願軟件包，全節點運算符需要手動升級以從修復程序中受益。

Currently, around 16% of node operators are running version 29.0. Adoption of the latest version is key to fully mitigating the attack. So, if you're running a full node, it might be time to consider an upgrade.

目前，約有16％的節點運營商正在運行29.0版。採用最新版本是完全緩解攻擊的關鍵。因此，如果您運行一個完整的節點，則可能是時候考慮升級了。

So, fingers crossed, this pesky bug is finally gone for good. But in the world of Bitcoin, you can never be too sure. Keep your nodes updated, and stay vigilant!

因此，手指交叉，這個討厭的蟲子終於永遠消失了。但是在比特幣的世界中，您永遠無法確定。保持您的節點更新，並保持警惕！
