使用比特幣核心客戶端確認大多數塊的有效性。

難怪在比特幣核心上工作的開發人員本身對比特幣有一定影響。

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.

使用比特幣核心客戶端確認大多數塊的有效性。難怪在比特幣核心上工作的開發人員本身對比特幣有一定影響。最近，他們一直在努力刪除塊中的任意數據（非貨幣數據，例如文本消息，圖片等）的限制。儘管比特幣社區的強烈反對，但比特幣核心開發人員還是與同齡人爭論實施。 Citrea被稱為實施的利益相關者。

What exactly Bitcoin Core is going to change?

到底要改變比特幣核心？

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.

比特幣核心將在下一版本中刪除OP_Return，該版本計劃於10月發布。 OP_Return是2014年添加到比特幣中的腳本比特幣核心開發人員。它的目的是限制每個塊中的任意數據（聖經經文，圖像等），並將其與與BTC交易相關的更多關鍵信息分開，以便網絡在與貨幣數據一起工作時忽略此數據。

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:

每個塊中只能有83個字節的空間，用於記錄在不承擔的TX輸出中的任意數據。值得注意的是，比特幣核心開發人員鼓勵比特幣不使用比特幣區塊鏈記錄任意數據，因為有更好的選項不會在比特幣網絡上施加額外的壓力。比特幣核心中的OP_RETRUN段0.9.0發行說明讀取：

“[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]不是對區塊鏈中存儲數據的認可。op_return變更會產生可證明的可靠的輸出，以避免數據存儲方案（其中一些已經部署） - 它們是存儲任意數據的，例如將圖像（例如永遠無用的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.”

將任意數據存儲在區塊鏈中仍然是一個壞主意。將非貨幣數據存儲在其他地方的成本較低，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年後，比特幣核心開發人員決定刪除83字節的限制，使用戶可以手動設置自己的限制。默認情況下，根本沒有限制。它可能會助長比特幣區塊鏈來支持各種媒體內容等。值得注意的是，即使有83個字節的限制，比特幣也一直用於任意數據交易。限制被認為可以使比特幣免受超負荷和垃圾郵件的影響。

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.

儘管社區受到了很多批評，但這些變化還是實施了。比特幣核心（Bitcoin Core）推動了變化引起的爭議，這使人們無法參與比特幣的技術背面。

Conflicting reasoning for the change

改變的推理矛盾

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日發布的一份聲明中，比特幣核心將抵抗審查制度作為改變的原因。但是開發人員彼得·托德（Peter Todd）創建了一個要求刪除OP_RETURN的拉請請求，他強調了另一個原因。他稱未負載TX輸出記錄的數據對開發人員負擔有害負擔，並強調完全刪除極限更有效：

“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 […]

“正如郵件列表討論中所討論的那樣，實體正在使用不可投入的輸出代替OP_Return輸出。正是由於尺寸限制。這不必要地增加了UTXO設置的尺寸，這是具有任意OP_Return Op_Return輸出限制的有害效果[…]

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.”

沒有理由應該強迫比特幣核心承擔維護我們認為無效甚至有害的任意限制的維護負擔。 ”

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.”

這種情況的問題之一是集中化問題。結軟軟件是比特幣核心的首選替代方案之一，但其對網絡的影響較低。正如彼得·托德（Peter Todd）在他的一條信息中所說的那樣：“我們……知道結，即使有50％的節點和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].”

同時，比特幣核心聲明說：“儘管我們認識到這種觀點並非所有用戶和開發人員普遍持有，但我們真誠地相信它符合比特幣及其用戶的最大利益，我們希望我們的用戶同意。”該聲明的這一部分與第二段有些衝突，其中指出：“比特幣核心的貢獻者無法執行[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.

使用比特幣機械手柄的海洋採礦高管假設檸檬色可以支持該提議。 Citrea是一家籌集了1400萬美元以在2024年向比特幣區塊鏈增加2層功能的公司。但是，Citrea的Jameson Lopps駁回了這些索賠。

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…

我對它的研究越多，如果得到的話，這不是技術辯論。這只是不好的演員，將惡意變化推向比特幣的謊言。
