【首都机场启用人脸识别安检 效率大幅提升】在北京，具备人脸识别功能的智能旅客安检系统亮相首都机场2号航站楼。旅客过检时，系统将对其进行身份识别和身份信息绑定，对常规行李物品，能在1分钟之内完成安全识别和处置，效率大幅提升。Passengers used to have to pass two manual ID checks to verify their boarding pass and ID, and have a photo taken at the second. This has since been replaced by the facial recognition. At the belongings security screening, passengers need to put their belongings in baskets, look at the camera facing them, and place the baskets on the conveyor. The system can process passenger information in less than a minute. The intelligent security system can process 266 passengers in one hour, 100 passengers more than before.

议题：比特币脚本2.0和加强支付通道

在比特币出现的头两年，中本聪对比特币脚本做了很多紧急修复。例如，比特币的脚本中删除了OP_VER和OP_VERIF，因为中本聪发现这些函数使得比特币软件的每次升级都成为一次硬分叉。
现在，通过SegWit（BIP141），区块中有一个见证的部分，允许引入一个新的脚本系统而不改变非见证区块脚本的大小。
目前有一些脚本正在研究中，它们旨在提升比特币交易的安全性，以及为比特币增加新的功能。这些新的脚本也会增强像闪电网络这样的第二层服务。
