据 U.Today 报道，比特币现金开发商 Jason Dreyzehner 宣布启动比特币现金主网重大升级，计划于 2025 年 5 月启动。
A major upgrade to the Bitcoin Cash mainnet has been activated at block 227,228 on the chipnet, incorporating two Bitcoin Cash Improvement Proposals (CHIPs).
比特币现金主网的重大升级已在芯片网络的第 227,228 号区块激活，其中包含两项比特币现金改进提案（CHIP）。
The Targeted Virtual Machine Limits CHIP optimizes Bitcoin Cash's denial-of-service defenses by increasing compute capabilities for real contracts by over 100 times while reducing worst-case node compute utilization by 50%. This adjustment simplifies contracts, streamlines contract audits, and bolsters overall security. The upgrade improves contract efficiency, making advanced use cases more feasible, such as post-quantum cryptography, stronger escrow and settlement strategies, zero-knowledge proofs, and homomorphic encryption. It also introduces new tooling and a cross-implementation benchmarking technique to consistently verify node performance.
目标虚拟机限制 CHIP 通过将真实合约的计算能力提高 100 倍以上，同时将最坏情况下的节点计算利用率降低 50%，优化了比特币现金的拒绝服务防御。此次调整简化了合同、简化了合同审核并增强了整体安全性。此次升级提高了合约效率，使高级用例更加可行，例如后量子密码学、更强大的托管和结算策略、零知识证明和同态加密。它还引入了新的工具和跨实施基准测试技术，以一致地验证节点性能。
The BigInt CHIP, also known as High-Precision Arithmetic for Bitcoin Cash, significantly reduces contract lengths by over tenfold, making previously theoretical applications immediately practical. This includes advanced automated market-making and exchange protocols, decentralized stablecoins, collateralized loan protocols, cross-chain and sidechain bridges, zero-knowledge proofs, post-quantum cryptography, and homomorphic encryption. The upgrade leverages Bitcoin Cash's scalable architecture to provide superior math capabilities, surpassing those of Ethereum, with "bare metal" performance, more byte-efficient, and cost-effective transactions. These enhancements are now accessible to Bitcoin Cash contracts on "layer one," ensuring censorship resistance and cross-contract compatibility without increasing compute requirements, allowing fully archiving Bitcoin Cash nodes to operate on low-cost consumer hardware.
BigInt CHIP，也称为比特币现金高精度算术，可将合约长度显着缩短十倍以上，使之前的理论应用立即变得实用。这包括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、后量子密码学和同态加密。此次升级利用比特币现金的可扩展架构来提供超越以太坊的卓越数学功能，并具有“裸机”性能、更高的字节效率和更具成本效益的交易。这些增强功能现在可供“第一层”上的比特币现金合约使用，确保审查阻力和跨合约兼容性，而无需增加计算要求，从而允许完全存档比特币现金节点在低成本消费硬件上运行。
Following the announcement, the price of Bitcoin Cash (BCH) showed a modest increase, rising 5% in the last 24 hours to $442, marking the second consecutive day of gains since November 15.
消息公布后，比特币现金（BCH）的价格小幅上涨，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。
