睡獅會醒來嗎？

這是最近比特幣生態系統中一些深層玩家的感覺。

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

比特幣生態系統中的一些深層玩家感到睡獅即將醒來。

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日的開發人員聲明顯示，下一個版本的比特幣核心可能會廢除OP_Return輸出的80字節限制。聲明說，OP_Return的80字節限制不再適合當前需求。首先，它很容易繞過，並且一些私人採礦加速器根本不執行這些限制。其次，它將形成扭曲的激勵機制，某些項目將激勵一些私人服務以繞過限制。同時，聲明說，廢除對OP_RETURN的80字節限制已得到廣泛的支持。

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字節限制的令牌部署格式OP-20出現在市場上。以相同名稱的代幣的非處方交易價格為OP_RETURN，每件400美元（每件1,000），而費用僅為每件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將簡要介紹OP_Return是什麼是，在成功升級後，升級將在比特幣網絡上具有哪些優點和弊端，以及使用此機制發行OP-20的前景。

The debate surrounding OP_RETURN

圍繞OP_Return的辯論

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.

在比特幣網絡中，OP_Return是專門用於攜帶交易中任意數據的腳本操作代碼（OPCODE）。 OP_Return輸出攜帶的數據將不會通過後續交易來引用，也不會佔據節點的UTXO空間。

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，比特幣節點必須永久保留所有未解決的輸出（UTXO）。惡意或不受控制的數據編寫會導致節點存儲壓力。因此，在2013年，社區通過添加即時無效腳本提出了“輕巧”數據存儲的想法。然後，在2014年，比特幣核心0.9.0正式納入了“標準輸出”類型中的OP_Return輸出，並將數據限制設置為40個字節，該字節逐漸增加到80字節，以平衡數據寫入需求和網絡資源保護。

OP_RETURN restrictions no longer meet the needs of Bitcoin ecosystem development

OP_Return限制不再滿足比特幣生態系統開發的需求

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，比特幣開發人員最初設計的op_return是為了防止節點過度擴展存儲，這是由於包含大量數據塊的處理腳本，並將其用作“區塊鏈的輕量級記錄”功能。但是，隨著比特幣生態系統的開發，各種資產協議，項目各方，L2和跨鏈橋需要記錄越來越多的鏈條數據，並且OP_Return的80字節限制逐漸限制了。

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.

為了滿足項目需求，各個項目各方必須通過各種操作繞過這一限制，包括向礦工提供高獎勵。因此，比特幣核心的核心貢獻者格雷格·桑德斯（Greg Sanders）在Github上發布了一份聲明，該聲明提議在下一個版本的Bitcoin Core中刪除80字節限制，並允許BitcoIn Core和任何數量和長度的OP_RET_RET_RET_RET_RETING。

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

他認為，刪除80字節限制將至少帶來兩個切實的好處：

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）它可以有效地減少比特幣區塊鏈中“高回報交易”和“低計算交易”的發生。這些交易的本質是使用少量交易來攜帶大量數據，從而對節點和網絡施加壓力。

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）它可以促進比特幣生態系統中新用例和應用的開發。例如，當前流行的BRC-20標準受到80字節有效載荷的限制，每筆交易最多可創建400個令牌。刪除80字節限制後，可以完全利用標準，並且可以支持更複雜和多樣化的用例。

Opposition remains strong

反對仍然強大

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.

但是實際上，比特幣核心尚未正式宣布下一次升級的特定日期。同時，在GitHub下仍然有許多反對意見，宣布了升級。

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.

社區成員Wizkid057說，這遠遠超過了一個小的技術變化，而是整個比特幣網絡本質的根本變化。比特幣網絡將成為任意數據存儲系統，而不是作為分散貨幣發展。同時，它還將更普遍地製作更多數據密集型協議（例如銘文，NFTS）和“垃圾”數據。

Upgrade not yet completed, coin issuance first

升級尚未完成，硬幣發行第一

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，儘管取消OP_RETURN的80字節上限的下一個版本的比特幣核心尚未完成，但打破此限制的令牌部署標準OP-20已悄悄地啟動，並且該協議的第一個標記，OP_Return，涉嫌已被弄髒。當前的非處方交易價格為US $
