BSC公司确认巴氏分叉将于八月下旬发布

cryptonews.ruPublished on 2026-08-14Last updated on 2026-08-14

Abstract

BNB Chain确认将于2026年8月25日02:30(UTC)在主网激活名为Pasteur的硬分叉。节点运营商需在此之前将客户端升级至1.7.7版本,否则可能面临断网风险。 此次硬分叉整合了BEP-673元提案下的多项升级,包括BEP-682、BEP-695和BEP-675。 BEP-682旨在修复跨链桥验证系统中的重复签名漏洞,确保验证者签名在计数前去除重复项,提升安全性。BEP-695则针对质押与治理系统,确保验证者更换共识密钥后,旧密钥立即失效,并防止其通过密钥轮换规避惩罚。 BEP-675是一项提升网络吞吐量的优化。它允许区块提议者提交已预先执行完毕的“完整区块”,验证者只需进行共识验证和签名,而无需重新执行交易。测试网数据显示,此举将验证者执行交易时间从125毫秒大幅降至15毫秒,网络吞吐量(TPS)提升近88%,同时平均区块Gas使用量显著增加,但最终确定延迟保持不变。 BNB Chain的硬分叉系列均以科学家命名,Pasteur是继Fermi(于2026年1月将区块时间降至0.45秒)后的最新升级。节点运营商和开发者需遵循官方文档进行准备,对于希望利用BEP-675的开发者,可能需要运行全节点而非轻节点。

$BNB Chain宣布,将于2026年8月25日 02:30 UTC 在$BNB Smart Chain (BSC)主网激活其巴氏分叉。

文件指出,所有节点运营商必须在此时间之前将客户端升级至1.7.7版本,否则存在断网风险。

BNB Chain在8月14日发布的博客文章中确认了日期和客户端要求。

BNB Chain的提案是否整合在了一次通用升级中?

巴氏分叉 包含 在元提案BEP-673中。然而,它也将另外三项提案——BEP-682、BEP-695和BEP-675——整合到了一次协调激活中。

BEP-682和BEP-695专注于桥接、质押和治理的安全性方面的工作。BEP-675是一个旨在提高吞吐量的提案,其在技术上不需要硬分叉即可运行。

$BNB Chain为其硬分叉有意选择了命名。它们都以科学家命名,包括帕斯卡、麦克斯韦、费米和孟德尔。每个硬分叉都为区块链带来了渐进式的变化。

费米分叉于2026年1月推出,帮助将BSC网络出块时间缩短至0.45秒。自那以后,网络一直稳定在这一水平,并未进一步加速。

消除桥接中重复验证系统的漏洞

BEP-682标准旨在修订BSC系统中跨链转账的验证方法。

当资产跨链转入时,BSC不会直接信任源区块链的声明。相反,它会调用位于地址0x67的预编译合约,该合约会根据已知的验证者集合统计验证者签名。只有在获得绝大多数签名后,转账才会执行。

然而,这种方法存在缺陷,因为无法确认每个验证者只出现一次。

一个特别设计的验证者集合可以多次列出同一签名者,在每次出现时都计算其投票权,从而以少于规则要求的真实签名数量突破阈值。

BEP-682在计数前会移除重复项,确保冗余数据集不再能突破阈值。

如何确保过时的验证者密钥真正失效

BEP-695标准旨在消除质押和治理系统中的漏洞。当验证者进行计划内技术维护而更换其共识密钥时,假设废弃的密钥不再拥有任何权限。

然而,过去情况并非完全如此。现在,针对每个BNB Chain的链,此问题已有三项修正。第一,旧的、已更换的密钥将失去其验证者管理员权限,而不再保留它们。

第二项修正确保验证者无法再通过密钥轮换来规避即将发生的惩罚(slash)。同时,它也阻止了黑名单地址参与基于签名的治理投票。

无燃料消耗或区块时间限制的“更满”区块

目前,BSC中的区块会执行两次。首次执行时,区块构建者运行交易以验证区块的有效性,随后验证者在签名前会再次运行所有这些交易。

然而,这个动作再次花费450毫秒(ms),而验证者花费在执行第二次查询上的时间,正是区块打包者浪费的可以用来打包下一个区块的时间。

BEP-675标准允许构建者传递一个他们已经执行完毕的区块。

这一次,验证者根据共识规则验证其合规性、进行签名、传播数据,然后完成完整性检查。

测试网收集的数据显示,验证者执行交易所花费的时间从125毫秒减少到了15毫秒。此外,吞吐量增长了近88%——从每秒1237笔交易(TPS)增至2324笔交易/秒,同时燃料上限1亿和450毫秒的间隔保持不变。

区块的平均燃料使用量从4635万增至8415万。交易最终确认的延迟保持不变。然而,BNB Chain强调,这些是受控负载下的指标。网络仍需承受主网的负载压力,特别是在多个构建者竞争同一区块槽位时。

节点运营商在25日之前需要做什么?

节点运营商是那些需要为巴氏分叉项目做准备的人。BNB Chain提供了关于如何操作以避免启动错误的详细文档。

希望采用BEP-675算法的构建者可能需要付出额外努力,因为这意味着需要运行一个全节点而不是快速同步节点,因为现在构建者需要创建已完全执行的区块。传统的交易打包方案继续有效,只是打包时间更短了。

Bitcoin Price Drops to $62,470 as Sellers Retest $63,000 Support Level

Bitcoin's price fell below $63,000 for a second consecutive day on Friday, hitting an intraday low of $62,470. The cryptocurrency later recovered to trade just above $63,000, leaving it nearly flat for the past 24 hours and for August overall, with a weekly loss of 2.6%. The volatility triggered significant liquidations, with $26 million of leveraged long Bitcoin positions liquidated over 24 hours. Market sentiment was further dampened by data showing over $131 million in outflows from spot Bitcoin ETFs for a second straight day, signaling a potential pullback by institutional investors. Adding to the negative pressure, index provider MSCI has proposed new criteria for "non-operating companies" in its global indexes, which could lead to the exclusion of firms holding significant digital assets like Bitcoin on their balance sheets. Companies such as Strategy and Metaplanet could be affected, potentially forcing index-tracking funds to sell their shares. Strategy publicly criticized the proposal, arguing digital assets are legitimate assets and index providers should not dictate what companies can own. Public consultations on MSCI's proposal end September 30, with a final decision expected by October 16. If approved, exclusions could begin in November, potentially triggering sustained institutional selling and damaging a key bridge for Bitcoin adoption in the corporate sector.
