比特币核心的磁盘填充错误：终于被压扁了吗？

比特币核心开发人员似乎终于消灭了自2020年以来一直困扰着完整节点操作员的讨厌磁盘填充攻击。

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年以来，比特币核心开发人员一直在与持续的磁盘填充攻击作斗争。最新消息表明他们可能最终将其压制！这篇博客文章介绍了这个长期存在的问题的细节和潜在的解决方案。

The Disk Fill Attack: A Nuisance for Full Nodes

磁盘填充攻击：完整节点的滋扰

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.

对于那些操作完整的比特币节点的人来说，磁盘填充攻击是一个真正的头痛。攻击者利用诸如logprintf之类的命令以过多，毫无意义的数据充斥节点的硬盘驱动器。对于带有旋转磁盘的较旧节点，这可能会瘫痪，并用垃圾装满他们的存储空间。

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.

甚至闪存存储也无法免疫。恒定的写作会降解磁盘，甚至导致整个机器崩溃。这就像被迫一遍又一遍地写下相同的句子，直到您的手痉挛并掉下来。

The Extermination Attempt: A Five-Year Saga

灭绝尝试：一个五年的传奇

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.

比特币核心拉的请求（PR）32604，复兴了几次尝试，代表了五年工作的高潮。高级比特币核心开发人员Gloria Zhao将Bug Patch 2D59977合并到主分支。该提交通过了所有支票，没有其他开发人员的负面感谢。

Bitcoin Core Version 30: Expanding OP_RETURN

比特币核心版本30：扩展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.

在其他新闻中，比特币Core即将推出的版本30（定于2025年10月）将大大提高OP_Return数据限制，从80个字节到近4 MB。这种变化使开发人员可以将更丰富的元数据放在链上。尽管支持者认为这可以使更复杂的数据驱动的比特币应用程序，但批评家表示担心它可能会膨胀区块链并对分散性产生负面影响。这是一个权衡，但可以为使用比特币打开新的门。

The Future: Hopeful, but Vigilant

未来：充满希望的，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，随着下一个比特币核心版本，该补丁将遍布整个网络，并最终结束磁盘填充攻击。作为一个自愿软件包，全节点运算符需要手动升级以从修复程序中受益。

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，约有16％的节点运营商正在运行29.0版。采用最新版本是完全缓解攻击的关键。因此，如果您运行一个完整的节点，则可能是时候考虑升级了。

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，这个讨厌的虫子终于永远消失了。但是在比特币的世界中，您永远无法确定。保持您的节点更新，并保持警惕！
