睡狮会醒来吗？

这是最近比特币生态系统中一些深层玩家的感觉。

Some deep players in the Bitcoin ecosystem are feeling that the sleeping lion is about to wake up.

比特币生态系统中的一些深层玩家感到睡狮即将醒来。

A developer statement on May 6 showed that the next version of Bitcoin Core may abolish the 80-byte limit on OP_RETURN output. The statement said that the 80-byte limit on OP_RETURN is no longer suitable for current needs. First, it is easily bypassed, and some private mining accelerators do not enforce these restrictions at all; second, it will form a distorted incentive mechanism, and some projects will incentivize some private services in order to bypass the restrictions. At the same time, the statement said that abolishing the 80-byte limit on OP_RETURN has received widespread support.

5月6日的开发人员声明显示，下一个版本的比特币核心可能会废除OP_Return输出的80字节限制。声明说，OP_Return的80字节限制不再适合当前需求。首先，它很容易绕过，并且一些私人采矿加速器根本不执行这些限制。其次，它将形成扭曲的激励机制，某些项目将激励一些私人服务以绕过限制。同时，声明说，废除对OP_RETURN的80字节限制已得到广泛的支持。

Currently, the token deployment format OP-20 that breaks the 80-byte limit of OP_RETURN has appeared in the market. The over-the-counter transaction price of the token with the same name op_return is US$400 per piece (1,000 per piece), while the cost is only US$5-6 per piece.

目前，打破OP_RETURN的80字节限制的令牌部署格式OP-20出现在市场上。以相同名称的代币的非处方交易价格为OP_RETURN，每件400美元（每件1,000），而费用仅为每件5-6美元。

In this article, Odaily Planet Daily will briefly introduce what OP_RETURN is, what pros and cons the upgrade will have on the Bitcoin network after it is successfully upgraded, and what the prospects are for issuing OP-20 using this mechanism.

在本文中，Odaily Planet Daily将简要介绍OP_Return是什么是，在成功升级后，升级将在比特币网络上具有哪些优点和弊端，以及使用此机制发行OP-20的前景。

The debate surrounding OP_RETURN

围绕OP_Return的辩论

In the Bitcoin network, OP_RETURN is a script operation code (opcode) specifically used to carry arbitrary data in transactions. The data carried by OP_RETURN output will not be referenced by subsequent transactions and will not occupy the node's UTXO space.

在比特币网络中，OP_Return是专门用于携带交易中任意数据的脚本操作代码（OPCODE）。 OP_Return输出携带的数据将不会通过后续交易来引用，也不会占据节点的UTXO空间。

In the early days, Bitcoin nodes had to keep all unspent outputs (UTXO) permanently. Malicious or uncontrolled data writing would cause node storage pressure. Therefore, in 2013, the community proposed the idea of "lightweighting" data storage by adding an immediate invalidation script. Then in 2014, Bitcoin Core 0.9.0 officially included OP_RETURN output into the "standard output" type, and set the data limit to 40 bytes, which was gradually increased to 80 bytes later to balance data writing needs and network resource protection.

在早期，比特币节点必须永久保留所有未解决的输出（UTXO）。恶意或不受控制的数据编写会导致节点存储压力。因此，在2013年，社区通过添加即时无效脚本提出了“轻巧”数据存储的想法。然后，在2014年，比特币核心0.9.0正式纳入了“标准输出”类型中的OP_Return输出，并将数据限制设置为40个字节，该字节逐渐增加到80字节，以平衡数据写入需求和网络资源保护。

OP_RETURN restrictions no longer meet the needs of Bitcoin ecosystem development

OP_Return限制不再满足比特币生态系统开发的需求

Therefore, Bitcoin developers originally designed OP_RETURN to prevent nodes from over-expanding storage due to processing scripts containing large blocks of data, and used it as a "lightweight record of the blockchain" function. However, with the development of the Bitcoin ecosystem, various asset protocols, project parties, L2, and cross-chain bridges need to record more and more data on the chain, and the 80-byte limit of OP_RETURN has gradually become restrictive.

因此，比特币开发人员最初设计的op_return是为了防止节点过度扩展存储，这是由于包含大量数据块的处理脚本，并将其用作“区块链的轻量级记录”功能。但是，随着比特币生态系统的开发，各种资产协议，项目各方，L2和跨链桥需要记录越来越多的链条数据，并且OP_Return的80字节限制逐渐限制了。

In order to meet project needs, various project parties have to bypass this limitation through various operations, including providing high rewards to miners, etc. Therefore, Greg Sanders, a core contributor of Bitcoin Core, released a statement on GitHub, proposing to remove the 80-byte limit in the next version of Bitcoin Core and allow OP_RETURN outputs of any number and length.

为了满足项目需求，各个项目各方必须通过各种操作绕过这一限制，包括向矿工提供高奖励。因此，比特币核心的核心贡献者格雷格·桑德斯（Greg Sanders）在Github上发布了一份声明，该声明提议在下一个版本的Bitcoin Core中删除80字节限制，并允许BitcoIn Core和任何数量和长度的OP_RET_RET_RET_RET_RETING。

He believes that the removal of the 80-byte limit will bring at least two tangible benefits:

他认为，删除80字节限制将至少带来两个切实的好处：

1) It can effectively reduce the occurrence of "high-reward transactions" and "low-count transactions" in the Bitcoin blockchain. The essence of these transactions is to use a small number of transactions to carry a large amount of data, thereby putting pressure on the nodes and the network.

1）它可以有效地减少比特币区块链中“高回报交易”和“低计算交易”的发生。这些交易的本质是使用少量交易来携带大量数据，从而对节点和网络施加压力。

2) It can promote the development of new use cases and applications in the Bitcoin ecosystem. For example, the BRC-20 standard, which is currently popular, is limited by the 80-byte payload to create a maximum of 400 tokens per transaction. After removing the 80-byte limit, the standard can be fully utilized, and more complex and diverse use cases can be supported.

2）它可以促进比特币生态系统中新用例和应用的开发。例如，当前流行的BRC-20标准受到80字节有效载荷的限制，每笔交易最多可创建400个令牌。删除80字节限制后，可以完全利用标准，并且可以支持更复杂和多样化的用例。

Opposition remains strong

反对仍然强大

But in fact, Bitcoin Core has not yet officially announced the specific date of the next upgrade. At the same time, there are still many objections under the GitHub where the upgrade was announced.

但是实际上，比特币核心尚未正式宣布下一次升级的特定日期。同时，在GitHub下仍然有许多反对意见，宣布了升级。

Community member wizkid057 said that this is far more than a small technical change, but a fundamental change to the nature of the entire Bitcoin network. The Bitcoin network will become an arbitrary data storage system instead of developing as a decentralized currency. At the same time, it will also make more data-intensive protocols (such as inscriptions, NFTs) and "junk" data more prevalent.

社区成员Wizkid057说，这远远超过了一个小的技术变化，而是整个比特币网络本质的根本变化。比特币网络将成为任意数据存储系统，而不是作为分散货币发展。同时，它还将更普遍地制作更多数据密集型协议（例如铭文，NFTS）和“垃圾”数据。

Upgrade not yet completed, coin issuance first

升级尚未完成，硬币发行第一

However, although the next version of Bitcoin Core to abolish the 80-byte upper limit of OP_RETURN has not yet been finalized, a token deployment standard OP-20 that breaks this limit has been quietly launched, and the first token of the protocol, op_return, is suspected to have been minted. The current over-the-counter transaction price is US$

但是，尽管取消OP_RETURN的80字节上限的下一个版本的比特币核心尚未完成，但打破此限制的令牌部署标准OP-20已悄悄地启动，并且该协议的第一个标记，OP_Return，涉嫌已被弄脏。当前的非处方交易价格为US $
