在比特幣社區中，激烈的辯論爆發了非財務數據是否應該在區塊鏈上佔有一席之地

關於非金融數據是否應該在區塊鏈上佔有一席之地，比特幣社區中正在進行一場激烈的技術和哲學辯論。

A heated technical and philosophical debate is unfolding within the Bitcoin community over whether non-financial data should have a place on the blockchain.

關於非金融數據是否應該在區塊鏈上佔有一席之地，比特幣社區中正在進行一場激烈的技術和哲學辯論。

At the centre of the dispute is a proposal to remove the size limit on a Bitcoin feature known as OP_RETURN, which some fear would open the door to more non-financial uses of the blockchain.

爭端的中心是刪除被稱為OP_RETURN的比特幣功能的尺寸限制的提議，有些擔心會打開區塊鏈更多非財務用途的大門。

OP_RETURN is an operation code in the Bitcoin scripting language that lets users embed arbitrary data in a transaction without transferring any coins. Currently, an OP_RETURN can consume 80 bytes of the maximum size of a traditional Bitcoin block, which is 1 megabyte (1,048,576 bytes). The proposed change would remove this limit, allowing OP_RETURN data to consume more space in each block.

OP_RETURN是比特幣腳本語言中的操作代碼，可讓用戶在交易中嵌入任意數據而無需轉移任何硬幣。目前，OP_RETURN可以消耗傳統比特幣塊最大尺寸的80個字節，即1兆字節（1,048,576字節）。提出的更改將消除此限制，從而允許OP_Return數據在每個塊中佔用更多空間。

While the proposal has raised some technical concerns, it later gained broader attention as it became a flashpoint in a larger ideological debate. The most outspoken critics, such as Bitcoin Core developer Peter Todd, invoked questions about Bitcoin’s identity and the degree of power its core developers hold.

儘管該提案引起了一些技術問題，但隨著它成為更大的意識形態辯論的閃點，它後來引起了廣泛的關注。比特幣核心開發人員彼得·托德（Peter Todd）等最直言不諱的評論家提到了有關比特幣身份的問題以及其核心開發人員所擁有的權力程度。

Satoshi Nakamoto’s original whitepaper referred to Bitcoin as a peer-to-peer electronic cash system, and many believe any other uses of the blockchain should be actively discouraged. Among those critics’ main concerns is that if the size limit on OP_RETURN is removed, it might lead to more "monkey jpegs" — a reference to NFTs like Yuga Labs’ Bored Apes Yacht Club — being stored on Bitcoin.

納卡本（Satoshi Nakamoto）的原始白皮書將比特幣稱為點對點電子現金系統，許多人認為，應積極勸阻區塊鏈的任何其他用途。在這些批評家的主要問題中，如果刪除了OP_Return的尺寸限制，則可能導致更多的“ Monkey Jpegs”（諸如Yuga Labs的無聊的Apes Yacht Club）的NFT被存儲在比特幣上。

They also pointed out several practical concerns about what uncapping OP_RETURN might mean for Bitcoin node operators and the Bitcoin network as a whole. For instance, they fear that it will increase the bandwidth and storage requirements for node operators, making it more expensive to run a full Bitcoin node.

他們還指出了關於對比特幣節點運算符和整個比特幣網絡可能意味著什麼的幾個實際問題。例如，他們擔心它會增加節點操作員的帶寬和存儲要求，從而使運行完整的比特幣節點更昂貴。

A Bitcoin node is software that connects to the Bitcoin network and helps enforce the rules of the protocol. Node operators are the gatekeepers of consensus and are vital in keeping Bitcoin secure, decentralised, and censorship-resistant. In particular, they defend Bitcoin’s rules as miners can’t change the protocol if nodes reject invalid blocks.

比特幣節點是連接到比特幣網絡並有助於執行協議規則的軟件。節點操作員是共識的守門人，對於確保比特幣安全，分散和耐心的耐心至關重要。特別是，他們捍衛比特幣的規則，因為如果節點拒絕無效的塊，則礦工將無法更改協議。

Those against raising the size limit of OP_RETURN also warned that it could increase demand for block space, driving up transaction fees and pricing out smaller financial transactions. However, Todd said during a recent debate that this is unlikely because of the financial incentives involved.

那些反對提高OP_Return尺寸限制的人還警告說，它可能會增加對塊空間的需求，增加交易費用並定價較小的金融交易。但是，托德在最近的辯論中說，這不太可能是因為涉及的經濟激勵措施。

Bitcoin Core and OP_RETURN

比特幣核心和op_return

Bitcoin Core is the reference implementation of the Bitcoin protocol — the official software used to run a full Bitcoin node. It’s the original and most widely used version of Bitcoin software, maintained by a decentralised group of developers and contributors.

比特幣核心是比特幣協議的參考實現 - 用於運行完整比特幣節點的官方軟件。它是由分散的開發人員和貢獻者保持的原始版本，最廣泛使用的比特幣軟件。

As such, the Bitcoin Core developers ultimately decide what changes will be included in the software and, by extension, which code modifications will be deployed across the network.

因此，比特幣核心開發人員最終決定軟件中將包含哪些更改，並且通過擴展，將在整個網絡中部署哪些代碼修改。

Todd explained that using OP_RETURN to store arbitrary data is about four times more expensive than another available mechanism. That mechanism is segregated witness (SegWit), the result of Bitcoin’s last major ideological battle, which took place between 2015 and 2017.

托德（Todd）解釋說，使用op_return存儲任意數據的貴四倍，是其他可用機制的貴四倍。該機制是隔離的見證人（Segwit），這是比特幣在2015年至2017年之間進行的最後一次重大意識形態戰的結果。

During that dispute, one camp advocated for increasing Bitcoin’s blocksize beyond 1MB, while the Bitcoin Core team and others argued against the change. This ultimately led to several "hard forks" of Bitcoin, namely Bitcoin Cash and Bitcoin Satoshi Vision, which increased the block size.

在這一爭端期間，一個營地主張將比特幣的阻滯劑增加超過1MB，而比特幣核心團隊和其他人則反對這一變化。這最終導致了比特幣的幾個“硬叉”，即比特幣現金和比特幣Satoshi Vision，這增加了塊大小。

Hard forks can be thought of as changes that do not maintain backwards compatibility, whereas soft forks are backwards-compatible. While the “big blockers” hard forked, Bitcoin Core implemented SegWit through a soft fork, allowing blocks to be up to 4MB in size.

可以將硬叉視為無法保持向後兼容的變化，而軟叉是向後兼容的。雖然“大型阻滯劑”硬分叉，但比特幣核心通過軟叉實現了Segwit，使塊的尺寸最高為4MB。

Bitcoin calculates fees based on the transaction size, with data in the witness portion of a block effectively getting a 75% discount.

比特幣根據交易規模計算費用，在街區的證人部分中，數據有效地獲得了75％的折扣。

“It’s not economically rational to put your monkey jpegs in OP_RETURN data,” Todd said. “This purely comes down to, in certain cases, for technical reasons, certain protocols need their data to be in output space; it can’t be in witness space.”

托德說：“將您的猴子jpegs放入OP_Return數據上是不合理的。” “在某些情況下，由於某些方案需要其數據在輸出空間中，這純粹歸結於某些情況下；它不能在證人空間中。”

Unspendable transaction outputs

不可投入的交易輸出

OP_RETURN is primarily used to store data on the Bitcoin blockchain in a provably unspendable way. Because it’s unspendable, OP_RETURN outputs are not stored in the Unspent Transaction Output (UTXO) database, which helps reduce Bitcoin node resource usage.

OP_RETURN主要用於以可證明的無人駕駛方式將數據存儲在比特幣區塊鏈上。由於它是不可投入的，因此OP_Return輸出未存儲在Untpent Transaction輸出（UTXO）數據庫中，這有助於減少比特幣節點資源的使用情況。

Bitcoin uses a UTXO-based model rather than keeping balances like a bank account. Therefore, your “wallet balance” is the value of the inputs minus the outputs. Every transaction consumes one or more UTXOs as inputs and creates new UTXO outputs. As a best practice, OP_RETURN outputs are given a value of 0 BTC.

比特幣使用基於UTXO的模型，而不是保持諸如銀行帳戶之類的餘額。因此，您的“錢包平衡”是輸入的值減去輸出。每次交易都會消耗一個或多個UTXO作為輸入，並創建新的UTXO輸出。作為最佳實踐，OP_Return輸出的值為0 BTC。

Todd explained that as things currently stand, protocols requiring more than 80 bytes of arbitrary data in output space are creating unspendable outputs that get added to the UTXO set.

托德（Todd）解釋說，隨著目前的影響，在輸出空間中需要超過80個任意數據的協議正在創建無法添加到UTXO集合的不可投放的輸出。
