语言学中有个叫“萨丕尔—沃尔夫假说”的理论，又被称作“语言相对论”，其提出的假设大致可以总结为：一个人母语的语法以及词语等方面的构成，可以影响其思维方式。
比如说“浅蓝”和“深蓝”这两个词，在汉语和英语中它们都是给“蓝”添加后缀而构成的。但在俄语，这两词的拼写完全不同，拉丁转写分别是“goluboy（浅蓝）”和“siniy（深蓝）”，在实验也证明了，在辨别深浅度不同的蓝色中，俄语母语者比英语母语者有更高的成功率
奥威尔的“Newspeak”或许也是这个理论的一个体现：如果一个概念在你的语言中根本不存在，你又怎么可能知道这个概念？

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.”
