比特币核心30更新将大大增加op_return函数的数据限制

即将在10月发布的即将发布的比特币核心30更新将大大提高OP_Return功能的数据限制 - 一种特殊的操作代码，允许用户将任意数据嵌入比特币交易中。

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.

即将推出的Bitcoin Core V30版本预计将于10月份引入OP_Return功能的数据限制。该特殊操作代码允许用户将任意数据嵌入比特币交易中，当前约束设置为80个字节。

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.

此更改的集成是更广泛的V30版本的一部分，该版本目前正在Mainnet发布之前在测试网上进行测试。

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.

根据开发人员的说法，默认的OP_Return数据限制将从80个字节调整为大约4MB，与比特币的现有块大小限制对齐。

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.

该修改旨在解决数据存储技术遇到的问题和未实用的交易输出集，该集合的输出密集地包装有小于80字节的输出。

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.

正如比特币开发人员Aben Ryley在GitHub上报道的那样，可以在启动时设置OP_Return的数据限制，默认值为4,194,209（2^22 + 1）字节。

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

此启动设置还将确定P2SH程序的数据限制。

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

最小无需交易输出大小将设置为55个字节，最小输入大小将设置为137字节。

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.

开发人员解释说，无需交易输出集集变得密集，其输出小于80字节，从而导致了测试人员使用的数据结构和存储技术的问题。

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

此外，对于使用低内存设备的测试仪，较低的未固定交易输出大小可能是有问题的。

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

可以在启动时调整OP_Return数据限制，最大限制为2^32-1。

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

启动设置还将确定P2SH程序的数据限制。

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版本将为比特币带来几个新功能，包括引入新的P2TR（付费接收机信任）输出类型和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.
