比特幣現金採用動態區塊大小限制以增強可擴展性和安全性

比特幣現金(BCH) 實施了自適應區塊大小限制演算法，解決了導致2017 年BCH/BTC 分裂的經濟漏洞。該演算法根據網路使用情況調整區塊大小限制，在不同使用水準下優化基礎設施成本。雖然比特幣預計即將發生減半事件，但 BCH 2024 年 5 月的升級預計將降低成本並增強網路安全性。

Bitcoin Cash Upgrades with Adaptive Blocksize Limit Algorithm

比特幣現金透過自適應區塊大小限制演算法進行升級

New York—Bitcoin Cash (BCH), the first hard fork of Bitcoin, has successfully implemented the CHIP-2023-04 Adaptive Blocksize Limit Algorithm on its chipnet blockchain, addressing an economic vulnerability that has persisted since 2010.

紐約——比特幣的第一個硬分叉比特幣現金(BCH) 已在其晶片網路區塊鏈上成功實施了CHIP-2023-04 自適應區塊大小限制演算法，解決了自2010 年以來一直存在的經濟漏洞。

Adaptive Blocksize Limit

自適應塊大小限制

This upgrade dynamically adjusts the block size limit of BCH, optimizing infrastructure costs during varying network usage levels. The algorithm automatically reduces the block size limit when network activity is low, conserving resources, and increases the limit during periods of rapid growth, accommodating increased demand.

此次升級動態調整 BCH 的區塊大小限制，在不同的網路使用水準下優化基礎設施成本。當網路活動較低時，此演算法會自動減少區塊大小限制，從而節省資源，並在網路活動快速增長期間增加限制，以滿足增加的需求。

Addressing Economic Vulnerability

解決經濟脆弱性

The 2010 vulnerability, which contributed to the 2017 BCH/BTC network split, stemmed from the use of a static block size limit. This limitation could result in excessive block sizes, driving up infrastructure costs and potentially compromising network security.

2010 年的漏洞源自於靜態區塊大小限制的使用，該漏洞導致了 2017 年 BCH/BTC 網路分裂。這種限制可能會導致區塊大小過大，從而增加基礎設施成本並可能損害網路安全。

Benefits of Adaptive Blocksize Limit

自適應塊大小限制的好處

The Adaptive Blocksize Limit Algorithm mitigates these vulnerabilities by:

自適應區塊大小限制演算法透過以下方式緩解這些漏洞：

• Reducing infrastructure costs during periods of low usage
• Enabling potential doubling of maximum block size annually during peak growth
• Thwarting attacks aimed at inflating participation costs

Comparison to Static Block Size

在低使用率期間降低基礎設施成本在高峰增長期間使最大區塊大小每年翻倍阻止旨在抬高參與成本的攻擊與靜態區塊大小的比較

Most Bitcoin-like networks, including Bitcoin (BTC), employ a fixed block size limit to prevent excessive block growth. However, this approach can lead to unpredictable transaction fees and confirmation times during periods of high network usage. Adaptive block size limits address these limitations by automatically adjusting the maximum block size over time.

大多數類似比特幣的網絡，包括比特幣（BTC），都採用固定的區塊大小限制來防止區塊過度成長。然而，這種方法可能會導致在網路使用率較高期間出現不可預測的交易費用和確認時間。自適應區塊大小限制透過隨著時間的推移自動調整最大區塊大小來解決這些限制。

Conservative and Responsive Algorithm

保守且響應式的演算法

The Bitcoin Cash algorithm is designed to be conservative and responsive to network activity. It gradually decreases the block size limit during periods of reduced usage and increases it during periods of rapid expansion, up to twice its current size annually.

比特幣現金演算法被設計為保守且對網路活動敏感。它在使用量減少期間逐漸減小塊大小限制，並在快速擴展期間增加區塊大小限制，每年達到目前大小的兩倍。

Market Reaction

市場反應

The Bitcoin Cash price has exhibited bullish momentum following the upgrade announcement. In the last 24 hours, BCH has surged by 14%, trading at $462.90 with a market capitalization of $9.1 billion. Trading volume has also increased significantly, currently at $826 million.

升級公告後，比特幣現金價格表現出看漲勢頭。過去24小時內，BCH飆升14%，交易價格為462.90美元，市值為91億美元。交易量也大幅增加，目前達到 8.26 億美元。

Upcoming Halving Event

即將到來的減半事件

Notably, Bitcoin Cash is set to undergo a halving event in 19 days, scheduled for April 4th. This adjustment will reduce the block reward from 6.25 BCH to 3.125 BCH, aligning with the halving event for Bitcoin, which is expected to occur 19 days later.

值得注意的是，比特幣現金將於 4 月 4 日經歷 19 天內的減半事件。此次調整將使區塊獎勵從 6.25 BCH 減少到 3.125 BCH，與預計 19 天後發生的比特幣減半事件一致。
