比特币现金开发者 Jason Dreyzehner 表示，2025 年 5 月对比特币现金的关键升级现已在主网上激活。

Bitcoin Cash (BCH) developer Jason Dreyzehner has announced the activation of the critical May 2025 upgrade on the Bitcoin Cash mainnet.

比特币现金 (BCH) 开发商 Jason Dreyzehner 宣布激活比特币现金主网上 2025 年 5 月的关键升级。

In a tweet, Dreyzehner shared that the May 2025 upgrade to Bitcoin Cash is now active on chipnet at block 227,228.

Dreyzehner 在推文中表示，2025 年 5 月对比特币现金的升级现已在芯片网络的第 227,228 号区块上激活。

This upgrade includes two Bitcoin Cash Improvement Proposals (CHIPs) which are Targeted Virtual Machine Limits CHIP and BigInt CHIP: High-Precision Arithmetic for Bitcoin Cash.

此次升级包括两项比特币现金改进提案（CHIP），分别是“目标虚拟机限制 CHIP”和“BigInt CHIP：比特币现金高精度算术”。

The May 2025 upgrade to Bitcoin Cash is now active on chipnet at block 227,228! 🎉 (0000000000b8dc4625844fa367b12317645fac7c9afbc5fb8def4025a6822c86)

2025 年 5 月对比特币现金的升级现已在芯片网络的区块 227,228 上激活！ 🎉（0000000000b8dc4625844fa367b12317645fac7c9afbc5fb8def4025a6822c86）

此次升级包括两项比特币现金改进提案（CHIP）：

Targeted Virtual Machine Limits CHIP

目标虚拟机限制 CHIP

The VM Limits CHIP retargets Bitcoin Cash's denial-of-service protection, dramatically increasing compute for real contracts by more than 100 times while reducing worst-case node compute utilization by 50%. By lowering overhead, retargeted limits simplify contracts, streamline contract audits and increase overall security.

VM Limits CHIP 重新定位了比特币现金的拒绝服务保护，将真实合约的计算量大幅提高了 100 倍以上，同时将最坏情况下的节点计算利用率降低了 50%。通过降低开销，重新定位的限制简化了合同、简化了合同审核并提高了整体安全性。

This upgrade improves contract efficiency, making important use cases more practical, such as post-quantum cryptography, stronger escrow and settlement strategies, zero-knowledge proofs, homomorphic encryption and other critical innovations for Bitcoin Cash's future security and competitiveness.

此次升级提高了合约效率，使重要用例更加实用，例如后量子密码学、更强大的托管和结算策略、零知识证明、同态加密以及其他对比特币现金未来安全性和竞争力至关重要的创新。

Finally, this release enhances the ecosystem by introducing new tooling and a cross-implementation benchmarking technique for continuously verifying node performance.

最后，该版本通过引入新的工具和跨实施基准测试技术来持续验证节点性能，从而增强了生态系统。

BigInt CHIP upgrade

BigInt芯片升级

The second upgrade, BigInt CHIP: High-Precision Arithmetic for Bitcoin Cash, offers over 10x reductions in contract lengths and makes previously theoretical use cases immediately practical. This includes more advanced automated market-making and exchange protocols, decentralized stablecoins, collateralized loan protocols, cross-chain and sidechain bridges, zero-knowledge proofs, post-quantum cryptography, homomorphic encryption and more.

第二次升级，BigInt CHIP：比特币现金的高精度算法，将合约长度缩短了 10 倍以上，并使之前的理论用例立即变得实用。这包括更先进的自动化做市和交易协议、去中心化稳定币、抵押贷款协议、跨链和侧链桥、零知识证明、后量子密码学、同态加密等等。

This upgrade fully utilizes Bitcoin Cash's fundamentally more scalable architecture to provide math capabilities that surpass those of Ethereum such as "bare metal" performance, more byte-efficient and cheaper transactions.

此次升级充分利用了比特币现金本质上更具可扩展性的架构，提供超越以太坊的数学功能，例如“裸机”性能、更高的字节效率和更便宜的交易。

These capabilities are now available to Bitcoin Cash contracts on "layer one," ensuring censorship resistance and cross-contract compatibility without increasing compute requirements, which implies that fully archiving Bitcoin Cash nodes can continue to operate on low-cost consumer hardware.

这些功能现在可用于“第一层”的比特币现金合约，确保审查阻力和跨合约兼容性，而无需增加计算要求，这意味着完全存档的比特币现金节点可以继续在低成本消费硬件上运行。

Overall, these enhancements aim to improve Bitcoin Cash capabilities. The price of the Bitcoin fork Bitcoin Cash (BCH) responded modestly to the news of the upgrade. At the time of writing, BCH has risen 5% in the last 24 hours to $442, marking the second straight day of gains since Nov. 15, assuming today closes in the green.

总体而言，这些增强功能旨在提高比特币现金的功能。比特币分叉比特币现金（BCH）的价格对升级的消息反应温和。截至撰写本文时，BCH 在过去 24 小时内上涨 5%，至 442 美元，这是自 11 月 15 日以来连续第二天上涨（假设今天收盘上涨）。
