比特幣現金 (BCH) 啟動 2025 年 5 月關鍵升級，針對虛擬機器限制和 BigInt CHIP

比特幣現金開發者 Jason Dreyzehner 表示，2025 年 5 月對比特幣現金的關鍵升級現已在主網上啟動。

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

比特幣現金 (BCH) 開發人員 Jason Dreyzehner 宣布啟動比特幣現金主網上 2025 年 5 月的關鍵升級。

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 月對比特幣現金的升級現已在晶片網路的第 227,228 號區塊上啟動。

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.

此次升級包括兩項比特幣現金改進提案（CHIP），分別是「目標虛擬機限制 CHIP」和「BigInt CHIP：比特幣現金高精度算術」。

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

此次升級包括兩項比特幣現金改進提案（CHIP）：

Targeted Virtual Machine Limits CHIP

目標虛擬機器限制 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 重新定位了比特幣現金的拒絕服務保護，將真實合約的計算量大幅提高了 100 倍以上，同時將最壞情況下的節點計算利用率降低了 50%。透過降低開銷，重新定位的限制簡化了合約、簡化了合約審核並提高了整體安全性。

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.

此次升級提高了合約效率，使重要用例更加實用，例如後量子密碼學、更強大的託管和結算策略、零知識證明、同態加密以及其他對比特幣現金未來安全性和競爭力至關重要的創新。

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

最後，該版本透過引入新的工具和跨實施基準測試技術來持續驗證節點效能，從而增強了生態系統。

BigInt CHIP upgrade

BigInt晶片升級

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.

第二次升級，BigInt CHIP：比特幣現金的高精度演算法​​，將合約長度縮短了 10 倍以上，並使先前的理論用例立即變得實用。這包括更先進的自動化做市和交易協議、去中心化穩定幣、抵押貸款協議、跨鍊和側鏈橋、零知識證明、後量子密碼、同態加密等等。

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.

此次升級充分利用了比特幣現金本質上更具可擴展性的架構，提供超越以太坊的數學功能，例如「裸機」性能、更高的位元組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.

這些功能現在可用於「第一層」的比特幣現金合約，確保審查阻力和跨合約相容性，而無需增加運算要求，這意味著完全存檔的比特幣現金節點可以繼續在低成本消費硬體上運行。

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.

總體而言，這些增強功能旨在提高比特幣現金的功能。比特幣分叉比特幣現金（BCH）的價格對升級的訊息反應溫和。截至撰寫本文時，BCH 在過去 24 小時內上漲 5%，至 442 美元，這是自 11 月 15 日以來連續第二天上漲（假設今天收盤上漲）。
