斯坦福大学提出防弹技术:可缩减比特币区块大小,增加保密性

斯坦福大学发布了一份标题为《防弹技术:对保密交易等的简短证明》 的论文,提出了一种新零知识证明系统:防弹技术(Bulletproofs)。 该提案增强了链上隐私保护,并提出了一种新的、更快速、更紧凑的方式来验证增强隐私的保密交易(Confidential Transactions,CT)。 具体来说,防弹技术可以大大减少这类交易需要验证的区块大小。 此外,论文的作者 -由Dan Boneh 教授监督的 斯坦福大学应用密码学小组- 已经在设法实现防弹技术。
目前,所有的交易信息 – 比如钱包地址,特别是比特币的发送量 – 都可以在比特币区块链上看到。 这会侵犯所有用户的隐私。 例如,如果我们希望通过比特币网络支付工资,这意味着每笔工资都将可在区块链网络上看到。 这反过来可能意味着某人(如你的房东)可能会查看你赚了多少钱来尝试增加租金。
提高区块链的保密性就需要用到保密交易技术。 保密交易技术结合了一些加密技术,以便只有交易的发送者和接收者才知道交易金额。 这些加密技术可以让用户混淆他们正在交易的金额,同时仍然允许旁观者对混淆的金额进行计算:任何人都可以检查发送的比特币的总和是否大于收到的比特币的总和。
保密交易技术是通过零知识证明来实现的。零知识证明是在不需要向对方发送关于保密交易本身任何信息的情况下,向对方证明保密交易有效的技术。

其实目前各个高校也都陆续开了关于区块链技术的课程,这项技术也会让越来越多的人关注并接受吧

这种技术应用成熟的话货币革命也不远了,到时候应该国家发行了

现在需要研究保护量子攻击, 以后的算力会越来越大

这个是比特币的瓶颈,有很多人开始做了,但是真的推广来还是有一定的时间的,至少目前不会。
