隐私与后量子安全:成为加密资产标配的关键
Eli Ben-Sasson 认为,如果开发人员能够将隐私保护和后量子安全性做得既负担得起又易于使用,它们将成为加密货币领域的标准功能。
Zcash 联合创始人 Eli Ben-Sasson 指出,要实现这一目标,关键在于降低使用门槛。他在社交媒体 X 上发布的内容强调,这两项功能必须具备易用性且成本低廉。他的这一预测将普通用户的实际体验与技术层面加强区块链网络的工作紧密联系在一起。
隐私工具与后量子防御的挑战
隐私工具旨在限制他人从公共区块链的交易中获取信息;与此同时,后量子方法则致力于保护数字资产免受未来强大量子计算机的攻击。尽管这两个目标面临不同的挑战,但 Ben-Sasson 认为可用性对于两者都至关重要。如果增强保护措施需要复杂的账户变更或高昂的交易费用,人们可能在采用时会遇到困难。
此外,他还提出了一个关于现有网络向后量子安全过渡的问题:开发人员必须评估网络的密码学基础,并清晰说明用户在资金处理方面需要采取的任何步骤。
比特币测试揭示量子保护的现实障碍
StarkWare, co-founded by Ben-Sasson, reported in August on an anti-quantum transaction experiment on the Bitcoin main network. This experimental method runs without changing the Bitcoin consensus rules, providing researchers with a practical test of possible defense mechanisms.
However, StarkWare emphasized that the transaction did not make Bitcoin itself quantum secure. Its approach protects only specific outputs, while the entire network still relies on cryptographic systems that may face future risks. The company estimates that the method will cost hundreds of dollars. In addition, such unusual transactions need to be sent to miners through a direct path rather than through Bitcoin's regular mempool.
These limitations illustrate why work presentations do not automatically provide accessible options to everyday users. As a result, Ben-Sasson calls for cost reductions, which apply to the entire process from technical research to wider application.
Zcash prepares to achieve faster block generation through NU7 upgrade
Zcash developers are separately preparing for an NU7 network upgrade to speed up block production. They plan to activate the upgrade on the testnet on October 6 and target to activate it on the mainnet on November 5.
NU7 将把区块之间的目标间隔从 75 秒缩短至 25 秒。同时,它将禁用版本 4 的交易,并引入与网络可持续性机制相关的更改。开发人员计划于 10 月 20 日根据测试网的部署结果决定主网激活事宜。值得注意的是,NU7 并未引入 Ben-Sasson 更广泛预测中所描述的后量子保护功能。
Grayscale 对 Zcash ETF 实施三拆一分割
另一项与 Zcash 相关的发展涉及投资者而非网络技术。在其 8 月推出不到一个月后,Grayscale 已为其 Zcash ETF(代码:ZCSH)安排了三股换一股的股票分割。
根据向美国证券交易委员会(SEC)提交的文件,截至 9 月 28 日市场收盘时的在册股东,每持有一股将获得两股额外股份。Grayscale 计划在 9 月 29 日市场收盘后分发这些股份,预计将于 9 月 30 日开始进行除权交易。
此次调整将使每位持有者的持股数量增加两倍,并相应降低每股的价值。因此,股票分割本身不会增加投资者的持仓价值或基金的基础资产价值。
总结
Ben-Sasson 的预测、NU7 的时间表以及 ZCSH 的股票分割关注的是 Zcash 生态系统中的不同部分。他的核心观点依然是一个预测:隐私和量子保护必须变得经济实惠且易于管理,才能被用户广泛接受。
