在比特币社区中，激烈的辩论爆发了非财务数据是否应该在区块链上占有一席之地

关于非金融数据是否应该在区块链上占有一席之地，比特币社区中正在进行一场激烈的技术和哲学辩论。

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

关于非金融数据是否应该在区块链上占有一席之地，比特币社区中正在进行一场激烈的技术和哲学辩论。

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.

争端的中心是删除被称为OP_RETURN的比特币功能的尺寸限制的提议，有些担心会打开区块链更多非财务用途的大门。

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是比特币脚本语言中的操作代码，可让用户在交易中嵌入任意数据而无需转移任何硬币。目前，OP_RETURN可以消耗传统比特币块最大尺寸的80个字节，即1兆字节（1,048,576字节）。提出的更改将消除此限制，从而允许OP_Return数据在每个块中占用更多空间。

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.

尽管该提案引起了一些技术问题，但随着它成为更大的意识形态辩论的闪点，它后来引起了广泛的关注。比特币核心开发人员彼得·托德（Peter Todd）等最直言不讳的评论家提到了有关比特币身份的问题以及其核心开发人员所拥有的权力程度。

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.

纳卡本（Satoshi Nakamoto）的原始白皮书将比特币称为点对点电子现金系统，许多人认为，应积极劝阻区块链的任何其他用途。在这些批评家的主要问题中，如果删除了OP_Return的尺寸限制，则可能导致更多的“ Monkey Jpegs”（诸如Yuga Labs的无聊的Apes Yacht Club）的NFT被存储在比特币上。

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.

他们还指出了关于对比特币节点运算符和整个比特币网络可能意味着什么的几个实际问题。例如，他们担心它会增加节点操作员的带宽和存储要求，从而使运行完整的比特币节点更昂贵。

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.

比特币节点是连接到比特币网络并有助于执行协议规则的软件。节点操作员是共识的守门人，对于确保比特币安全，分散和耐心的耐心至关重要。特别是，他们捍卫比特币的规则，因为如果节点拒绝无效的块，则矿工将无法更改协议。

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.

那些反对提高OP_Return尺寸限制的人还警告说，它可能会增加对块空间的需求，增加交易费用并定价较小的金融交易。但是，托德在最近的辩论中说，这不太可能是因为涉及的经济激励措施。

Bitcoin Core and OP_RETURN

比特币核心和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.

比特币核心是比特币协议的参考实现 - 用于运行完整比特币节点的官方软件。它是由分散的开发人员和贡献者保持的原始版本，最广泛使用的比特币软件。

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，比特币核心开发人员最终决定软件中将包含哪些更改，并且通过扩展，将在整个网络中部署哪些代码修改。

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）解释说，使用op_return存储任意数据的贵四倍，是其他可用机制的贵四倍。该机制是隔离的见证人（Segwit），这是比特币在2015年至2017年之间进行的最后一次重大意识形态战的结果。

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.

在这一争端期间，一个营地主张将比特币的阻滞剂增加超过1MB，而比特币核心团队和其他人则反对这一变化。这最终导致了比特币的几个“硬叉”，即比特币现金和比特币Satoshi Vision，这增加了块大小。

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.

可以将硬叉视为无法保持向后兼容的变化，而软叉是向后兼容的。虽然“大型阻滞剂”硬分叉，但比特币核心通过软叉实现了Segwit，使块的尺寸最高为4MB。

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

比特币根据交易规模计算费用，在街区的证人部分中，数据有效地获得了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.”

托德说：“将您的猴子jpegs放入OP_Return数据上是不合理的。” “在某些情况下，由于某些方案需要其数据在输出空间中，这纯粹归结于某些情况下；它不能在证人空间中。”

Unspendable transaction outputs

不可投入的交易输出

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主要用于以可证明的无人驾驶方式将数据存储在比特币区块链上。由于它是不可投入的，因此OP_Return输出未存储在Untpent Transaction输出（UTXO）数据库中，这有助于减少比特币节点资源的使用情况。

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.

比特币使用基于UTXO的模型，而不是保持诸如银行帐户之类的余额。因此，您的“钱包平衡”是输入的值减去输出。每次交易都会消耗一个或多个UTXO作为输入，并创建新的UTXO输出。作为最佳实践，OP_Return输出的值为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）解释说，随着目前的影响，在输出空间中需要超过80个任意数据的协议正在创建无法添加到UTXO集合的不可投放的输出。

“Over time, this causes issues because your UTX

“随着时间的流逝，这会引起问题，因为您的UTX
