比特幣核心30更新將大大增加op_return函數的數據限制

即將在10月發布的即將發布的比特幣核心30更新將大大提高OP_Return功能的數據限制 - 一種特殊的操作代碼，允許用戶將任意數據嵌入比特幣交易中。

The upcoming Bitcoin Core v30 release, anticipated for October, will introduce a substantial increase in the data limit for the OP_RETURN function. This special operational code allows users to embed arbitrary data in Bitcoin transactions, with the current constraint set at 80 bytes.

即將推出的Bitcoin Core V30版本預計將於10月份引入OP_Return功能的數據限制。該特殊操作代碼允許用戶將任意數據嵌入比特幣交易中，當前約束設置為80個字節。

The integration of this change is part of the broader v30 release, which is currently undergoing testing on the testnet ahead of the mainnet launch in the fall.

此更改的集成是更廣泛的V30版本的一部分，該版本目前正在Mainnet發布之前在測試網上進行測試。

According to developers, the default OP_RETURN data limit will be adjusted from 80 bytes to approximately 4MB, aligning with Bitcoin's existing block size limits.

根據開發人員的說法，默認的OP_Return數據限制將從80個字節調整為大約4MB，與比特幣的現有塊大小限制對齊。

The modification aims to address issues encountered with data storage techniques and the unspent transaction output set, which becomes densely packed with outputs smaller than 80 bytes.

該修改旨在解決數據存儲技術遇到的問題和未實用的交易輸出集，該集合的輸出密集地包裝有小於80字節的輸出。

As reported by Bitcoin developer Aben Ryley on GitHub, the data limit for OP_RETURN can be set at startup, with a default value of 4,194,209 (2^22 + 1) bytes.

正如比特幣開發人員Aben Ryley在GitHub上報導的那樣，可以在啟動時設置OP_Return的數據限制，默認值為4,194,209（2^22 + 1）字節。

This startup setting will also determine the data limit for P2SH programs.

此啟動設置還將確定P2SH程序的數據限制。

The minimum unspent transaction output size will be set to 55 bytes, and the minimum input size will be set to 137 bytes.

最小無需交易輸出大小將設置為55個字節，最小輸入大小將設置為137字節。

The developers explained that the unspent transaction output set becomes densely packed with outputs smaller than 80 bytes, leading to issues with data structures and storage techniques used by testers.

開發人員解釋說，無需交易輸出集集變得密集，其輸出小於80字節，從而導致了測試人員使用的數據結構和存儲技術的問題。

Moreover, lower unspent transaction output sizes can be problematic for testers using low-memory devices.

此外，對於使用低內存設備的測試儀，較低的未固定交易輸出大小可能是有問題的。

The OP_RETURN data limit can be adjusted at startup, with a maximum limit of 2^32 - 1.

可以在啟動時調整OP_Return數據限制，最大限制為2^32-1。

The startup setting will also determine the data limit for P2SH programs.

啟動設置還將確定P2SH程序的數據限制。

The v30 release will bring several new features to Bitcoin, including the introduction of a new P2TR (Pay to Relayer Trust) output type and updates to the coinbase transaction.

V30版本將為比特幣帶來幾個新功能，包括引入新的P2TR（付費接收機信任）輸出類型和Coinbase Transaction的更新。

It will also set the stage for the development of the next Bitcoin Core release, v31, which is expected to focus on privacy-enhancing technologies.output: The upcoming Bitcoin Core v30 release, anticipated for October, will introduce a substantial increase in the data limit for the OP_RETURN function.
