Mozilla基金会调查了上到宝马奔驰下到日产尼桑特斯拉的25个主流汽车品牌。发现对用户隐私的保护全灭，所有的品牌的车型都在采集非必要隐私数据，并且越是智能现代化，对用户的个人信息采集程度就越高：
随着车内传感器越来越多，他们能记录周边影像，录制车内声音，获取位置情报，你什么时候打开车门，甚至你的性别和取向，自然不会放过你连接手机后的通讯录乃至音乐列表。
而84%的品牌明言他们在和其他公司共享你的隐私，76%的品牌更是直说：老子不仅采集共享，还要贩卖你的个人情报。汽车行业成了所有行业里对隐私侵害最狠的一个，汽车则成了迫真的移动刺客居家间谍。

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
