Bitcoin Core 27.0 Release Enhances Bitcoin Network Security and Functionality

Bitcoin Core 27.0 发布增强了比特币网络安全性和功能

March 2, 2023: Bitcoin Core, the foundation software for running the Bitcoin network, has introduced a comprehensive suite of enhancements and updates with the official launch of version 27.0. This upgrade signifies a commitment to bolstering the network's security, efficiency, and overall functionality, solidifying its role as a robust and decentralized digital currency ecosystem.

2023 年 3 月 2 日：运行比特币网络的基础软件 Bitcoin Core 推出了一整套增强功能和更新，并正式发布了 27.0 版本。此次升级标志着我们致力于增强网络的安全性、效率和整体功能，巩固其作为强大且去中心化的数字货币生态系统的作用。

Key Features and Changes

主要特点和变化

Deprecated Features and Future Replacements

已弃用的功能和未来的替代品

Bitcoin Core 27.0 deprecates the "libbitcoinconsensus" library, which has been an integral part of the network for almost a decade. The library's functionality will no longer receive updates beyond the Taproot protocol upgrade, marking a shift towards "libbitcoinkernel." This new library offers a robust API that directly interacts with the unspent transaction output (UTXO) set for transaction and block validation.

Bitcoin Core 27.0 弃用了“libbitcoinconsensus”库，该库近十年来一直是网络不可或缺的一部分。该库的功能将不再接收 Taproot 协议升级之外的更新，这标志着向“libbitcoinkernel”的转变。这个新库提供了一个强大的 API，可以直接与未花费的交易输出 (UTXO) 集进行交互，以进行交易和区块验证。

Enhanced Security Protocols

增强的安全协议

The update introduces a major upgrade to data handling by altering the format of the mempool.dat file, which stores unconfirmed transactions. The new format employs XOR encryption of transaction contents, safeguarding it from potential alterations by external software such as antivirus programs. For those requiring a downgrade, a fallback option to the old format is available.

该更新通过更改存储未确认交易的 mempool.dat 文件的格式，对数据处理进行了重大升级。新格式采用交易内容的 XOR 加密，保护其免受防病毒程序等外部软件的潜在更改。对于需要降级的用户，可以使用旧格式的后备选项。

Network and Peer-to-Peer Enhancements

网络和点对点增强

Bitcoin Core 27.0 rolls out the second version of BIP324 (BIP324 v2) transport layer by default, enhancing secure connection protocols across the network. This improvement underscores the importance of precise system time settings by node operators for maintaining consensus integrity, as network-adjusted time has been removed from the consensus code.

Bitcoin Core 27.0默认推出第二版BIP324（BIP324 v2）传输层，增强整个网络的安全连接协议。这一改进强调了节点运营商精确的系统时间设置对于维护共识完整性的重要性，因为网络调整时间已从共识代码中删除。

Mempool Policy Innovations

Mempool 政策创新

A pivotal change introduced in version 27.0 is the implementation of Topologically Restricted Until Confirmation (TRUC) transactions. This new policy, currently applicable only on test networks, aims to improve the incentive structure surrounding transaction replacements and fee-bumping reliability by imposing constraints on the spending of unconfirmed outputs.

27.0 版本中引入的一个关键变化是拓扑限制直至确认 (TRUC) 事务的实现。这项新政策目前仅适用于测试网络，旨在通过对未经确认的输出的支出施加限制来改善围绕交易替代和费用上涨可靠性的激励结构。

RPC and External Signing Updates

RPC 和外部签名更新

Adjustments have been made to the "addnode" RPC to align with the new "-v2transport" default setting. Support for external signing on Windows systems has been temporarily suspended due to dependencies on an outdated library, but plans are underway to re-enable it once an alternative solution is integrated.

对“addnode”RPC 进行了调整，以与新的“-v2transport”默认设置保持一致。由于依赖于过时的库，Windows 系统上对外部签名的支持已暂时暂停，但我们正在计划在集成替代解决方案后重新启用它。

Development and Wallet Optimization

开发和钱包优化

The development process for Bitcoin Core now requires a C++20 capable compiler, reflecting the project's commitment to adopting modern programming standards. Wallet enhancements include the implementation of the CoinGrinder algorithm to optimize transaction cost-efficiency at higher fee rates and adjustments to the Branch and Bound algorithm to accommodate specific transaction fee strategies.

Bitcoin Core 的开发过程现在需要一个支持 C++20 的编译器，这反映了该项目对采用现代编程标准的承诺。钱包增强功能包括实施 CoinGrinder 算法以在更高的费率下优化交易成本效率，以及调整 Branch and Bound 算法以适应特定的交易费用策略。

Upgrade Instructions

升级说明

Users are advised to upgrade to Bitcoin Core 27.0 by shutting down any older versions running and installing the new release. The process varies slightly depending on the operating system but remains straightforward. Compatibility extends to systems with Linux Kernel 3.17+, macOS 11.0+, and Windows 7 or newer.

建议用户通过关闭任何运行的旧版本并安装新版本来升级到 Bitcoin Core 27.0。该过程根据操作系统的不同略有不同，但仍然很简单。兼容性扩展到采用 Linux Kernel 3.17+、macOS 11.0+ 和 Windows 7 或更高版本的系统。

Implications for the Bitcoin Network

对比特币网络的影响

The release of Bitcoin Core 27.0 is expected to significantly impact the operational dynamics of the Bitcoin network's underlying infrastructure. With enhancements focused on security, efficiency, and robust transaction handling, this version aims to reinforce the network's resilience against evolving threats and address scalability challenges. It underscores the ongoing commitment to maintaining Bitcoin's position as a secure and reliable digital currency for the global financial landscape.
