使用比特币核心客户端确认大多数块的有效性。

难怪在比特币核心上工作的开发人员本身对比特币有一定影响。

The validity of most blocks is confirmed using the Bitcoin Core client. No wonder developers working on Bitcoin Core have some influence on Bitcoin per se. Lately, they have been pushing to remove limits on arbitrary data from blocks (non-monetary data, such as text messages, pictures, and more). Despite the backlash from the Bitcoin community, the Bitcoin Core developers pushed for implementation, arguing with their peers. Citrea is named as the implementation’s stakeholder.

使用比特币核心客户端确认大多数块的有效性。难怪在比特币核心上工作的开发人员本身对比特币有一定影响。最近，他们一直在努力删除块中的任意数据（非货币数据，例如文本消息，图片等）的限制。尽管比特币社区的强烈反对，但比特币核心开发人员还是与同龄人争论实施。 Citrea被称为实施的利益相关者。

What exactly Bitcoin Core is going to change?

到底要改变比特币核心？

Bitcoin Core will remove OP_RETURN in the next version, scheduled for release in October. OP_RETURN is a script Bitcoin Core devs added to Bitcoin in 2014. It aimed to limit the arbitrary data (Bible verses, images, etc) in each block and separate it from more crucial information associated with BTC transactions so that the network would ignore this data while working with monetary data.

比特币核心将在下一版本中删除OP_Return，该版本计划于10月发布。 OP_Return是2014年添加到比特币中的脚本比特币核心开发人员。它的目的是限制每个块中的任意数据（圣经经文，图像等），并将其与与BTC交易相关的更多关键信息分开，以便网络在与货币数据一起工作时忽略此数据。

There can be only 83 bytes of space per block intended for arbitrary data recorded in unspendible TX outputs. It’s worth noting that Bitcoin Core developers have encouraged bitcoiners not to use the Bitcoin blockchain for recording arbitrary data, as there are better options that would not pile extra pressure on the Bitcoin network. The OP_RETRUN segment in the Bitcoin Core 0.9.0 release description reads:

每个块中只能有83个字节的空间，用于记录在不承担的TX输出中的任意数据。值得注意的是，比特币核心开发人员鼓励比特币不使用比特币区块链记录任意数据，因为有更好的选项不会在比特币网络上施加额外的压力。比特币核心中的OP_RETRUN段0.9.0发行说明读取：

“[OP_RETURN] is not an endorsement of storing data in the blockchain. The OP_RETURN change creates a provably-prunable output, to avoid data storage schemes – some of which were already deployed – that were storing arbitrary data such as images as forever-unspendable TX outputs, bloating bitcoin’s UTXO database.

“ [op_return]不是对区块链中存储数据的认可。op_return变更会产生可证明的可靠的输出，以避免数据存储方案（其中一些已经部署） - 它们是存储任意数据的，例如将图像（例如永远无用的TX Eutputs），Bloating Bitation utcoin的UTXO DATABASE。

Storing arbitrary data in the blockchain is still a bad idea; it is less costly and far more efficient to store non-currency data elsewhere.”

将任意数据存储在区块链中仍然是一个坏主意。将非货币数据存储在其他地方的成本较低，效率更高。”

However, 11 years later, Bitcoin Core developers decided to remove the 83-byte limit, allowing users to set their own limits manually. By default, there will be no limitations at all. It may fuel the use of the Bitcoin blockchain for backing various media content, etc. It’s worth noting that even with an 83-byte limit, Bitcoin has always been used for arbitrary data transactions. The limit is thought to keep Bitcoin safe from overloading and spam.

但是，11年后，比特币核心开发人员决定删除83字节的限制，使用户可以手动设置自己的限制。默认情况下，根本没有限制。它可能会助长比特币区块链来支持各种媒体内容等。值得注意的是，即使有83个字节的限制，比特币也一直用于任意数据交易。限制被认为可以使比特币免受超负荷和垃圾邮件的影响。

The changes were implemented despite much criticism from the community. The way Bitcoin Core was pushing the change stirred controversy that reached people not engaged in the tech backrooms of Bitcoin.

尽管社区受到了很多批评，但这些变化还是实施了。比特币核心（Bitcoin Core）推动了变化引起的争议，这使人们无法参与比特币的技术背面。

Conflicting reasoning for the change

改变的推理矛盾

In a statement released on June 6, Bitcoin Core cited censorship resistance as the reason for the change. But developer Peter Todd, who created a pull request calling for the removal of OP_RETURN, highlighted a different reason. He called the data recorded in unspendable TX outputs a harmful burden for developers and highlighted that removing the limit altogether is more efficient:

在6月6日发布的一份声明中，比特币核心将抵抗审查制度作为改变的原因。但是开发人员彼得·托德（Peter Todd）创建了一个要求删除OP_RETURN的拉请请求，他强调了另一个原因。他称未负载TX输出记录的数据对开发人员负担有害负担，并强调完全删除极限更有效：

“As was discussed in the mailing list discussion, entities are using unspendable outputs in lieu of OP_Return outputs. Precisely because of the size limit. This increases the UTXO set size unnecessarily, a harmful effect of having the arbitrary OP_Return output limitations […]

“正如邮件列表讨论中所讨论的那样，实体正在使用不可投入的输出代替OP_Return输出。正是由于尺寸限制。这不必要地增加了UTXO设置的尺寸，这是具有任意OP_Return Op_Return输出限制的有害效果[…]

There’s no reason why Bitcoin Core should be forced to take on the maintenance burden of maintaining arbitrary limits that we believe are ineffective, and even harmful.”

没有理由应该强迫比特币核心承担维护我们认为无效甚至有害的任意限制的维护负担。”

One of the problems with this case is the issue of centralization. The Knots software is one of the preferred alternatives to Bitcoin Core, but its influence on the network is way lower. As Peter Todd puts it in one of his messages, “We … know that Knots isn’t going to be effective at preventing transactions from being mined even if it gets, say, 50% of nodes and 25% of hash power. You need Bitcoin Core on board to have any chance of success.”

这种情况的问题之一是集中化问题。结软软件是比特币核心的首选替代方案之一，但其对网络的影响较低。正如彼得·托德（Peter Todd）在他的一条信息中所说的那样：“我们……知道结，即使有50％的节点和25％的哈希功率。

At the same time, the Bitcoin Core statement reads, “While we recognize that this view isn’t held universally by all users and developers, it is our sincere belief that it is in the best interest of Bitcoin and its users, and we hope our users agree.” This portion of the statement somewhat conflicts with the second paragraph, which states, “Bitcoin Core contributors are not in a position to mandate [certain policies].”

同时，比特币核心声明说：“尽管我们认识到这种观点并非所有用户和开发人员普遍持有，但我们真诚地相信它符合比特币及其用户的最大利益，我们希望我们的用户同意。”该声明的这一部分与第二段有些冲突，其中指出：“比特币核心的贡献者无法执行[某些政策]。”

An Ocean Mining executive using the Bitcoin Mechanic handle assumes that Citrea could back the proposal. Citrea is the company that raised $14 million to add layer 2 functionality to Bitcoin blockchain in 2024. However, Jameson Lopps of Citrea dismissed these claims.

使用比特币机械手柄的海洋采矿高管假设柠檬色可以支持该提议。 Citrea是一家筹集了1400万美元以在2024年向比特币区块链增加2层功能的公司。但是，Citrea的Jameson Lopps驳回了这些索赔。

The more I look into it the worse if gets.Again this isn't a technical debate. It's just bad actors pushing malicious changes into Bitcoin lying about the effects they will have.Citrea *need* your mempool to tolerate their junk, and Core are determined to help them with that by…

我对它的研究越多，如果得到的话，这不是技术辩论。这只是不好的演员，将恶意变化推向比特币的谎言。
